Question

在我的应用程序中，我创建的自定义对话框没有完整的高度，我无法更改和自定义。例如，请看这个屏幕截图：

enter image description here 我的代码：

final Dialog contacts_dialog = new Dialog(ActivityGroup.this, R.style.theme_sms_receive_dialog);
contacts_dialog.setContentView(R.layout.dialog_schedule_date_time);
contacts_dialog.setCancelable(true);
contacts_dialog.setCanceledOnTouchOutside(true);
contacts_dialog.show();

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layoutRoot"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@null"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/shape_header_dialog_background"
        android:orientation="horizontal"
        android:padding="4dp" >

        <TextView
            android:id="@+id/TextView21"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_marginRight="5dp"
            android:layout_weight="2"
            android:gravity="center_vertical|right"
            android:text="@string/choose_schedule_time_date"
            android:textColor="#ffffff"
            android:textSize="14sp"
            android:textStyle="bold" />

        <ImageView
            android:id="@+id/ImageView03"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_marginTop="0dp"
            android:background="@drawable/icon_scudule_time" />
    </LinearLayout>

</LinearLayout>

风格：

<style name="theme_sms_receive_dialog" parent="android:style/Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="numberPickerStyle">@style/NPWidget.Holo.Light.NumberPicker</item>
</style>

Answer 1

您需要获取当前窗口并将其设置为LayoutParams，如下所示：

Dialog d=new Dialog(mContext);
.........
.........
myDialog.show();
Window window = myDialog.getWindow();
window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

备选方案（如果上述解决方案无效）

如果上述代码效果不佳，您可以使用解决方法

styles.xml

<style name="mydialog"></style>

爪哇

Dialog d=new Dialog(mContext,R.style.mydialog);
.........
.........
myDialog.show();
Window window = myDialog.getWindow();
window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

Answer 2

这可以通过两种方式完成，第一种在style.xml中，第二种在代码中：

在style.xml中添加如下内容，更改值（目前为90％）以满足您的需求。

<style name="Theme_Dialog" parent="android:Theme.Holo.Dialog">
    <item name="android:windowMinWidthMajor">90%</item>
    <item name="android:windowMinWidthMinor">90%</item>
</style>

将setlayout添加到match_parent

 final Dialog contacts_dialog = new Dialog(ActivityGroup.this,
 R.style.theme_sms_receive_dialog);
 contacts_dialog.setContentView(R.layout.dialog_schedule_date_time);

getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT);

 contacts_dialog.setCancelable(true);
 contacts_dialog.setCanceledOnTouchOutside(true);
 contacts_dialog.show();

Answer 3

对于全角度对话框，您可以为对话框创建自定义样式。下面给出了全宽度对话框的代码：

<style name="Custom_Dialog" parent="ThemeOverlay.AppCompat.Light" >
    <item name="windowMinWidthMajor">100%</item>
    <item name="windowMinWidthMinor">65%</item>
</style>

要将此样式指定给对话框的构造函数，请在onCreate()后立即将其添加到setContentView()方法：

getWindow()
    .setLayout(
        ViewGroup.LayoutParams.FILL_PARENT,
        ViewGroup.LayoutParams.WRAP_CONTENT
    );

Answer 4

您不需要为此添加任何样式

  Dialog dialog = new Dialog(context);
  dialog.setContentView(R.layout.your_layout_here);
  dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
  dialog.show();

注意：使用空的style会浪费处理器内部的内存时间。而是直接使用dailog.getWindow().setLayout(width,height)。

Answer 5

如果有人想知道如何对使用DialogFragment显示的对话框执行此操作，则可以覆盖onCreateDialog以返回具有windowMinWidthMajor并且次要设置为90的自定义样式的对话框％

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new Dialog(getActivity(), R.style.WideDialog);
}

风格：

<style name="WideDialog" parent="Base.Theme.AppCompat.Dialog">
    <item name="android:windowMinWidthMajor">90%</item>
    <item name="android:windowMinWidthMinor">90%</item>
</style>

Answer 6

在我的情况下，自定义对话框的宽度在大小（宽度）上缩小，因为即使设置了width属性，对话框内的内容的宽度也会变小

android:layout_width="match_parent"

我只是将宽度固定为屏幕尺寸，现在根据我的要求进行操作

android:layout_width="320dp"

Answer 7

使用“相对布局”而不是“线性”布局来获得“自定义对话框”的完整宽度。

Answer 8

要打开对话框时添加代码

       final Dialog mBottomSheetDialog = new Dialog(getActivity(), R.style.MaterialDialogSheet);

        mBottomSheetDialog.setContentView(R.layout.dialog_mainscreen_filter); // your custom view.
        mBottomSheetDialog.setCancelable(true);
        mBottomSheetDialog.getWindow().setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        mBottomSheetDialog.getWindow().setGravity(Gravity.BOTTOM);
        mBottomSheetDialog.show();


        ImageView img_cross = mBottomSheetDialog.findViewById(R.id.img_cross);
        final ImageView img_new = mBottomSheetDialog.findViewById(R.id.img_new);
        final ImageView img_Used = mBottomSheetDialog.findViewById(R.id.img_Used);


        img_cross.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mBottomSheetDialog.dismiss();
            }
        });


        img_new.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                img_new.setImageResource(R.drawable.checkbox_tick);
                img_Used.setImageResource(R.drawable.checkbox_tick_gray);
            }
        });
        img_Used.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                img_Used.setImageResource(R.drawable.checkbox_tick);
                img_new.setImageResource(R.drawable.checkbox_tick_gray);
            }
        });

anim / popup_hide.xml

        <?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android">

Dialog dialog = new Dialog(BASE_CONTEXT, R.style.Theme_Dialog);  
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);  
dialog.setContentView(R.layout.your_layout);  
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);

Answer 10

@Override public void onStart() {
    super.onStart();
    Dialog dialog = getDialog();
    if (dialog != null) {
        dialog.getWindow()
                .setLayout((int) (getScreenWidth(getActivity()) * .9), (int)(getScreenHeight(getActivity()) * .6) );
    }
}

public static int getScreenWidth(Activity activity) {
    Point size = new Point();
    activity.getWindowManager().getDefaultDisplay().getSize(size);
    return size.x;
}

public static int getScreenHeight(Activity activity) {
    Point size = new Point();
    activity.getWindowManager().getDefaultDisplay().getSize(size);
    return size.y;
}

90％宽度和60％高度的例子

Answer 11

MyDialogFragment myDialogFragment = 
    new MyDialogFragment(activity,arraylist.get(position).getImage());
                                myDialogFragment.show();

Window window = myDialogFragment.getWindow();
        window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);

Answer 12

这可以视为设置布局宽度（例如1000dp）和高度换行内容的简单技巧就像：

const module: TestingModule = await Test.createTestingModule({
  providers: [{
   provide: OperationDocumentService,
   useValue: {
     findById: () => OperationDocumentMock,
   },
 }]
});

Answer 13

与其使用自定义对话框，不如使用活动类。在清单文件中，如下指定样式属性

android:theme="@style/AppThemeDialog"

并按如下所示添加AppThemeDialog

<style name="AppThemeDialog" parent="Theme.AppCompat">

<item name="colorBackgroundFloating">#ff424242</item> <item name="listPreferredItemPaddingLeft">0dp</item> <item name="android:windowIsFloating">true</item> <item name="listPreferredItemPaddingRight">0dp</item> </style>

Answer 14

使用UserDefaults使一切变得有趣。这是我的代码

filter(_:)

和结果

Answer 15

只需尝试将对话框布局包装在RelativeLayout中

Answer 16

您可以通过编程方式设置对话框的宽度和高度。

dialog = new Dialog(this);
dialog.setContentView(R.layout.dialog_create_subcategory);
dialog.getWindow().setLayout(width, height);

Android获得自定义Dialog的全宽
