Question

我想创建一个自定义对话框，如下所示

enter image description here

我尝试了以下事项。

我创建了 AlertDialog.Builder 的子类，并使用了自定义标题和自定义内容视图并使用了该视图但结果与预期不符。
另一种尝试是继承 DialogFragment 并自定义onCreateDialog中的对话框，但结果不符合预期。
然后我尝试使用普通的 Dialog 类。结果并不像预期的那样。

在所有三种情况下，问题是当我忽略标题视图时对话框的大小不符合预期，当我使用标题视图时，结果是内容视图周围有一个粗边框（实际上看起来很糟糕）。现在我脑子里有两个问题......

我怎样才能做到这一点？由于我已经尝试了很多这样的事情，因此将更加赞赏直接的答案。
在Android应用中显示错误或提醒对话框的最佳方法是什么？

修改 Android Developer Documentation建议我们使用DialogFragments或Dialogs向用户显示错误/警报消息。但有一次他们说......

提示：如果需要自定义对话框，则可以将“活动”显示为对话框，而不是使用“对话框API”。只需创建一个活动，并将其主题设置为清单元素中的Theme.Holo.Dialog。

那是什么意思？使用Activity只是为了显示错误信息???

这里我创建了一个简单的Dialog，如：

Dialog Box

<强> custom_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold"/>


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_marginLeft="5dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="No"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

</LinearLayout>

您必须extends Dialog和implements OnClickListener

public class CustomDialogClass extends Dialog implements
    android.view.View.OnClickListener {

  public Activity c;
  public Dialog d;
  public Button yes, no;

  public CustomDialogClass(Activity a) {
    super(a);
    // TODO Auto-generated constructor stub
    this.c = a;
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.custom_dialog);
    yes = (Button) findViewById(R.id.btn_yes);
    no = (Button) findViewById(R.id.btn_no);
    yes.setOnClickListener(this);
    no.setOnClickListener(this);

  }

  @Override
  public void onClick(View v) {
    switch (v.getId()) {
    case R.id.btn_yes:
      c.finish();
      break;
    case R.id.btn_no:
      dismiss();
      break;
    default:
      break;
    }
    dismiss();
  }
}

如何拨打对话？

R.id.TXT_Exit:
CustomDialogClass cdd=new CustomDialogClass(Values.this);
cdd.show();

更新

很长一段时间后，我的一个朋友让我做了一个透明背景的弯曲形状对话框。所以，我在这里实现了它。

enter image description here

要制作曲线形状，您需要创建一个单独的curve_shap.XML，如下所示

<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#000000" />

    <stroke
        android:width="2dp"
        android:color="#ffffff" />

    <corners
        android:bottomLeftRadius="20dp"
        android:bottomRightRadius="20dp"
        android:topLeftRadius="20dp"
        android:topRightRadius="20dp" />

</shape>

现在，在主视图布局中添加此curve_shap.XML。就我而言，我使用了LinearLayout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="80dp"
        android:background="@drawable/curve_shap"
        android:orientation="vertical" >
...
</LinearLayout>

如何调用此方法？

CustomDialogClass cdd = new CustomDialogClass(MainActivity.this);
cdd.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
cdd.show();

我希望这适合你。

Answer 2

这是一个示例对话框，使用xml创建。

enter image description here

下一个代码xml只是一个例子，设计或视图在这里实现：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffffff">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="120dp"
    android:id="@+id/a"
    android:gravity="center"
    android:background="#DA5F6A"
    android:src="@drawable/dialog_cross"
    android:scaleType="fitCenter" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TEXTO"
    android:id="@+id/text_dialog"
    android:layout_below="@+id/a"
    android:layout_marginTop="20dp"
    android:layout_marginLeft="4dp"
    android:layout_marginRight="4dp"
    android:layout_marginBottom="20dp"
    android:textSize="18sp"
    android:textColor="#ff000000"
    android:layout_centerHorizontal="true"
    android:gravity="center_horizontal" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="30dp"
    android:text="OK"
    android:id="@+id/btn_dialog"
    android:gravity="center_vertical|center_horizontal"
    android:layout_below="@+id/text_dialog"
    android:layout_marginBottom="20dp"
    android:background="@drawable/btn_flat_red_selector"
    android:layout_centerHorizontal="true"
    android:textColor="#ffffffff" />

</RelativeLayout>

这行代码是drawable的资源：

android:src="@drawable/dialog_cross"
android:background="@drawable/btn_flat_red_selector"

你可以做一个类扩展Dialog，也是这样的：

public class ViewDialog {

    public void showDialog(Activity activity, String msg){
        final Dialog dialog = new Dialog(activity);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.dialog);

        TextView text = (TextView) dialog.findViewById(R.id.text_dialog);
        text.setText(msg);

        Button dialogButton = (Button) dialog.findViewById(R.id.btn_dialog);
        dialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

        dialog.show();

    }
}

最后是您的活动上的调用形式，例如：

ViewDialog alert = new ViewDialog();
alert.showDialog(getActivity(), "Error de conexión al servidor");

我希望它适合你。

Answer 3

另一种简单的方法。

步骤1）创建一个具有正确id的布局。

步骤2）在任何您想要的地方使用以下代码。

LayoutInflater factory = LayoutInflater.from(this);
final View deleteDialogView = factory.inflate(R.layout.mylayout, null);
final AlertDialog deleteDialog = new AlertDialog.Builder(this).create();
deleteDialog.setView(deleteDialogView);
deleteDialogView.findViewById(R.id.yes).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        //your business logic 
        deleteDialog.dismiss();
    }
});
deleteDialogView.findViewById(R.id.no).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        deleteDialog.dismiss();    
    }
});

deleteDialog.show();

Answer 4

在values -> style.xml

中添加以下主题

<style name="Theme_Dialog" parent="android:Theme.Light">
     <item name="android:windowNoTitle">true</item>
     <item name="android:windowBackground">@android:color/transparent</item>
</style>

在onCreateDialog方法中使用此主题，如下所示：

Dialog dialog = new Dialog(FlightBookActivity.this,R.style.Theme_Dialog);

在xml文件中定义包含标题栏的对话框布局，并将xml文件设置为：

dialog.setContentView(R.layout.your_dialog_layout);

Answer 5

简单首先创建一个类

#include <stdio.h>

int global = 5;

void foo(int *bar){
    *bar = 6;
    printf("bar = %d\nglobal = %d", *bar, global);
}

int main(){
    foo(&global);
    return 0;
}

然后创建custom_dialogbox_otp

 public class ViewDialog {

        public void showDialog(Activity activity, String msg){
            final Dialog dialog = new Dialog(activity);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(false);
            dialog.setContentView(R.layout.custom_dialogbox_otp);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

            TextView text = (TextView) dialog.findViewById(R.id.txt_file_path);
            text.setText(msg);

            Button dialogBtn_cancel = (Button) dialog.findViewById(R.id.btn_cancel);
            dialogBtn_cancel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
                    dialog.dismiss();
                }
            });

            Button dialogBtn_okay = (Button) dialog.findViewById(R.id.btn_okay);
            dialogBtn_okay.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Okay" ,Toast.LENGTH_SHORT).show();
                    dialog.cancel();
                }
            });

            dialog.show();
        }
    }

然后在你的drawable创建xml文件下面 for round_layout_white_otp.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="330dp"
    android:layout_height="160dp"

    android:orientation="vertical"
    android:padding="5dp"
    android:weightSum="100">

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/round_layout_otp"
        android:orientation="vertical"
        android:padding="7dp"
        android:weightSum="100">

        <LinearLayout
            android:layout_width="match_parent"

                    android:layout_height="50dp"
                    android:background="#DA5F6A"
                    android:gravity="center"
                    android:scaleType="fitCenter"
                    android:src="@mipmap/infoonetwo" />

            </LinearLayout>

            <LinearLayout
                android:layout_width="match_parent"

                dialog.dismiss();

            }
        });

    }

Answer 7

创建自定义对话框的最简单方法：

初始化并显示对话框：

 ViewDialog alertDialoge = new ViewDialog();
 alertDialoge.showDialog(getActivity(), "PUT DIALOG TITLE");

创建方法：

public class ViewDialog {

  public void showDialog(Activity activity, String msg) {

    final Dialog dialog = new Dialog(activity);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setCancelable(false);
    dialog.setContentView(R.layout.custom_dialoge_feedback);

    TextView text = (TextView) dialog.findViewById(R.id.text_dialog_feedback);
    text.setText(msg);

    Button okButton = (Button) dialog.findViewById(R.id.btn_dialog_feedback);
    Button cancleButton = (Button) dialog.findViewById(R.id.btn_dialog_cancle_feedback);
    final EditText edittext_tv = (EditText) dialog.findViewById(R.id.dialoge_alert_text_feedback);

    okButton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //Perfome Action
        }
    });
    cancleButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.dismiss();
        }
    });

    dialog.show();

    }
}

创建您想要或需要的布局XML。

Answer 8

您可以尝试使用这个简单的android dialog popup library来删除混乱的对话框代码。在您的活动中使用非常简单。之后，您可以在活动中显示此代码以显示对话框

Pop.on(this).with().title(R.string.title).layout(R.layout.custom_pop).show();

其中 R.layout.custom_pop 是您想要装饰对话框的自定义布局。

Answer 9

我发现这是显示自定义对话框的最简单方法。

您有布局your_layout.xml

public void showCustomDialog(final Context context) {
    Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = inflater.inflate(R.layout.your_layout, null, false);
    findByIds(view);  /*HERE YOU CAN FIND YOU IDS AND SET TEXTS OR BUTTONS*/
    ((Activity) context).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE | WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
    dialog.setContentView(view);
    final Window window = dialog.getWindow();
    window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    window.setBackgroundDrawableResource(R.color.colorTransparent);
    window.setGravity(Gravity.CENTER);
    dialog.show();
}

Answer 10

更改背景颜色和文字样式的最简单方法是为Android警报对话框制作自定义主题，如下所示： -

：将下面的代码放在styles.xml：

    <style name="AlertDialogCustom" parent="@android:style/Theme.Dialog">
    <item name="android:textColor">#999999</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
    <item name="android:typeface">monospace</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:textSize">@dimen/abc_text_size_medium_material</item>
    <item name="android:background">#80ff00ff</item>
</style>

：现在自定义事情已经完成，现在只适用于您的alertBuilder对象：

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this,R.style.AlertDialogCustom);

希望，这会对你有帮助！

Answer 11

创建自定义警报布局custom_aler_update.xml

然后复制到活动

        AlertDialog basic_reg;
    AlertDialog.Builder builder ;
    builder = new AlertDialog.Builder(ct, R.style.AppCompatAlertDialogStyle);
    LayoutInflater inflater = ((Activity) ct).getLayoutInflater();
    View v = inflater.inflate(R.layout.custom_aler_update, null);
    builder.setView(v);
    builder.setCancelable(false);
    builder.create();
    basic_reg = builder.show();

腼腆的风格

  <style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/primaryTextColor</item>
    <item name="android:background">@color/white</item>
</style>

Answer 13

创建警告对话框布局类似

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/btn"
        android:layout_width="match_parent"
        android:text="Custom Alert Dialog"
        android:layout_height="40dp">
    </Button>
</LinearLayout>

并在Activity类上添加以下代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    LayoutInflater inflate = LayoutInflater.from(this);
    alertView = inflate.inflate(R.layout.your_alert_layout, null);
    Button btn= (Button) alertView.findViewById(R.id.btn);

    showDialog();
  }

 public void showDialog(){
        Dialog alertDialog = new Dialog(RecognizeConceptsActivity.this);
        alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        alertDialog.setContentView(alertView);
        alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        alertDialog.show();
    }

Answer 14

它是Alert Dialog的一个类，因此您可以从任何活动调用该类来重用代码。

public class MessageOkFragmentDialog extends DialogFragment {
Typeface Lato;
String message = " ";
String title = " ";
int messageID = 0;

public MessageOkFragmentDialog(String message, String title) {
    this.message = message;
    this.title = title;
}


@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();

    View convertview = inflater.inflate(R.layout.dialog_message_ok_box, null);


    Constants.overrideFonts(getActivity(), convertview);
    Lato = Typeface
            .createFromAsset(getActivity().getAssets(), "font/Lato-Regular.ttf");


    TextView textmessage = (TextView) convertview
            .findViewById(R.id.textView_dialog);

    TextView textview_dialog_title = (TextView) convertview.findViewById(R.id.textview_dialog_title);

    textmessage.setTypeface(Lato);
    textview_dialog_title.setTypeface(Lato);



    textmessage.setText(message);
    textview_dialog_title.setText(title);



    Button button_ok = (Button) convertview
            .findViewById(R.id.button_dialog);
    button_ok.setTypeface(Lato);

    builder.setView(convertview);
    button_ok.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            dismiss();

        }
    });


    return builder.create();

}
}

同样的Xml文件是：

    <?xml version="1.0" encoding="utf-8"?>

Answer 15

Dialog Fragment是创建自定义Alert Dialog的最简单方法。按照上面的代码为对话框创建自定义视图，然后使用Dialog Fragment实现它。将以下代码添加到布局文件中：

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical">

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold" />


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"

我喜欢使用tcAron库。（在此处下载：https://github.com/triocoder/tcAron）

导入类：

导入com.triocoder.tcaron.tcaronlibrary.tcAronDialogs;
这样写：

tcAronDialogs.showFancyAlert（MainActivity.this，false，“ Text”，“ Close”，“ ic_hub_white”，0xFFF44336）;

Answer 17

Kotlin中的全屏自定义警报对话框类

创建XML文件，与创建活动相同

创建AlertDialog自定义类

class Your_Class(context:Context) : AlertDialog(context){

 init {
  requestWindowFeature(Window.FEATURE_NO_TITLE)
  setCancelable(false)
 }

 override fun onCreate(savedInstanceState: Bundle?) {
  super.onCreate(savedInstanceState)
  setContentView(R.layout.your_Layout)
  val window = this.window
  window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
                     WindowManager.LayoutParams.MATCH_PARENT)

  //continue custom code here
  //call dismiss() to close
 }
}

在活动中调用对话框

val dialog = Your_Class(this)
//can set some dialog options here
dialog.show()

注意**：如果您不想全屏显示活动，请删除以下几行

      val window = this.window
      window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
                         WindowManager.LayoutParams.MATCH_PARENT)

然后将XML文件中顶部布局的layout_width和layout_height编辑为wrap_content或固定DP值。

我一般不建议这样做，因为您可能希望您的应用程序适应多种屏幕尺寸，但是，如果将尺寸值保持足够小，就可以了

  public void showDialog(String title, String des, int icon) {

    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.custom_dialog);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    Button cancelBTN = dialog.findViewById(R.id.cancelBTN);
    Button acceptBTN = dialog.findViewById(R.id.acceptBtn);
    TextView tvTitle = dialog.findViewById(R.id.title);
    TextView tvDescription = dialog.findViewById(R.id.description);
    ImageView ivIcon = dialog.findViewById(R.id.icon);

    tvTitle.setText(title);
    tvDescription.setText(des);
    ivIcon.setImageResource(icon);

    cancelBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
        }
    });

    acceptBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

    dialog.show();
}

像这样打电话：

showDialog（“标题”，“消息”，R.drawable.warning）;

这是创建自定义对话框的非常简单的方法。

dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">
<!--  Put your layout content  -->
</LinearLayout>

MainActivity.java

ShowPopup(){
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.dialog, null);
android.app.AlertDialog.Builder alertDialogBuilder = new 
android.app.AlertDialog.Builder(this);
alertDialogBuilder.setView(promptsView);
alertDialogBuilder.setCancelable(true);
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}

只需调用此函数

 public void openPhotoDialog() {
    final Dialog dialog = new Dialog(this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.dialog_choose_photo);
    dialog.setCancelable(true);

    // Setting dialogview

    final Window window = dialog.getWindow();
    window.setLayout(AbsListView.LayoutParams.MATCH_PARENT, AbsListView.LayoutParams.WRAP_CONTENT);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    WindowManager.LayoutParams wlp = window.getAttributes();

    wlp.gravity = Gravity.BOTTOM;
    window.addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
    window.setDimAmount(0.5f);
    window.setAttributes(wlp);


    TextView txt_camera = dialog.findViewById(R.id.txt_camera);
    TextView txt_gallery = dialog.findViewById(R.id.txt_gallery);
    TextView txt_cancel_dialog = dialog.findViewById(R.id.txt_cancel_dialog);

    txt_camera.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            dialog.dismiss();
        }
    });
    txt_gallery.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            dialog.dismiss();
        }
    });
    txt_cancel_dialog.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            dialog.dismiss();
        }
    });

    dialog.show();

}

bg_dialog_smallround_white.xml可绘制资源

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/white" />

<corners
    android:radius="@dimen/_5sdp" />
