Question

我正在为我的应用程序构建一个自定义警报对话框我已编写代码及其工作但唯一的问题是它的大小不会根据我在对话框中的内容进行调整。下面是我的代码：

public class CustomDialogBoxActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button = (Button)findViewById(R.id.Button01main);

        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                final Dialog myDialog = new Dialog(CustomDialogBoxActivity.this);
                myDialog.setContentView(R.layout.dialog_sms_layout);
                myDialog.setTitle("Select any one");


                Button ok = (Button)myDialog.findViewById(R.id.buttonOK);
                final RadioGroup radioGrp = (RadioGroup)myDialog.findViewById(R.id.radioGroupSmsDialog);

                final CheckBox mob1 = (CheckBox)myDialog.findViewById(R.id.checkBoxMob1);
                final CheckBox mob2 = (CheckBox)myDialog.findViewById(R.id.checkBoxMob2);
                mob1.setText("9029691986");
                mob2.setText("99263911766");

                ok.setOnClickListener(this);

                ok.setOnClickListener(new OnClickListener() {

                    @Override
                    public void onClick(View v) {
                        // TODO Auto-generated method stub
                        if(mob1.isChecked() && mob2.isChecked()) {
                            if(radioGrp.getCheckedRadioButtonId() == R.id.radioSms) {
                                String[] phoneArray = {mob1.getText().toString(),mob2.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());
                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Message",phoneArray);

                            }else if(radioGrp.getCheckedRadioButtonId() == R.id.radioBusinessCard) {
                                String[] phoneArray = {mob1.getText().toString(),mob2.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());
                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Business Card",phoneArray);
                            }
                        }else if(mob1.isChecked() && !mob2.isChecked()) {
                            if(radioGrp.getCheckedRadioButtonId() == R.id.radioSms) {
                                String[] phoneArray = {mob1.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());                                
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Message",phoneArray);

                            }else if(radioGrp.getCheckedRadioButtonId() == R.id.radioBusinessCard) {
                                String[] phoneArray = {mob1.getText().toString()};

                                Log.v("MOB1",mob1.getText().toString());                                
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Business Card",phoneArray);
                            }

                        }else if(!mob1.isChecked() && mob2.isChecked()) {
                            if(radioGrp.getCheckedRadioButtonId() == R.id.radioSms) {
                                String[] phoneArray = {mob2.getText().toString()};

                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Message",phoneArray);

                            }else if(radioGrp.getCheckedRadioButtonId() == R.id.radioBusinessCard) {
                                String[] phoneArray = {mob2.getText().toString()};

                                Log.v("MOB2",mob2.getText().toString());
                                Log.v("Mobile No", ""+phoneArray.toString());
                                sendSms("SMS Business Card",phoneArray);
                            }

                        }else if(!mob1.isChecked() && !mob2.isChecked()) {
                            Toast.makeText(getApplicationContext(), "Select atleast one number", Toast.LENGTH_SHORT).show();
                        }                       
                    }
                });
                myDialog.show();
            }

        });
    }

    public void sendSms(String message,String[] phoneNumber) {

        Intent smsIntent = new Intent(Intent.ACTION_VIEW);
        smsIntent.setData(Uri.parse("sms:"));
        smsIntent.putExtra("sms_body", message);
        smsIntent.putExtra("address", phoneNumber);
        startActivity(smsIntent);       
    }
}

这是我点击按钮的output

这是我的main.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="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="This is my main activity, from here, I want to display a dialog, 
                        after the user clicked the button below this text." />

    <Button
        android:id="@+id/Button01main"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Show Dialog" />

</LinearLayout>

这是我的dialog_sms_layout

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

<RadioGroup
        android:id="@+id/radioGroupSmsDialog"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
         >

        <RadioButton
            android:id="@+id/radioSms"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:checked="true"
            android:text="SMS" />

        <RadioButton
            android:id="@+id/radioBusinessCard"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Card" />
    </RadioGroup>

<CheckBox
    android:id="@+id/checkBoxMob1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:text="Primary" />

<CheckBox
    android:id="@+id/checkBoxMob2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Secondary" />

<Button
    android:id="@+id/buttonOK"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:text="OK" />

</LinearLayout>

我想调整对话框大小请帮忙。提前谢谢

Answer 1

我不确定这是否适合您的情况，但如果您想将其设置为全宽或类似的东西，您需要获取活动的当前窗口并设置它的布局参数如下：

myDialog.show();
Window window = myDialog.getWindow();
window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);

修改

FILL_PARENT已弃用，请改用

window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

Answer 2

你只需要添加样式＆＃34; Theme_AppCompat_Light_Dialog_Alert＆＃34;这样的对话框：

Dialog dialog = new Dialog(context, R.style.Theme_AppCompat_Light_Dialog_Alert);

，您的对话框看起来像普通警报对话框

Answer 3

我通过使用此代码删除标题栏来解决此问题

    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

并在布局中的元素中添加填充以按对话框拉伸对话框。

    android:textColor="@android:color/white" />
   </LinearLayout>

Dialog class :- 

dialog = new Dialog(mContext);
dialog.setContentView(R.layout.dialog_feedback);
dialog.show();

Answer 5

使用Relative_Layout而不是Linear_layout获取“自定义对话框”的完整宽度。我不知道为什么，但是对我有用。

Answer 6

Okey，我找不到解决的办法，但我发现搁浅了：在根布局周围创建一个RelaytiveLayout包装，然后将重力设置为居中，如下所示：

<RelativeLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:gravity="center">
    
   <YourRootLayoutHere/>

</RelativeLayout

Answer 7

    private void showdialog() {
    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.activity_disclaimer);
    dialog.show();
    Window window = dialog.getWindow();
    window.setLayout(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
    Button dialogButton = (Button) dialog.findViewById(R.id.ok);
    dialogcb= (CheckBox) dialog.findViewById(R.id.checkBox);
    dialogButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            accepted = dialogcb.isChecked();
            SharedPreferences.Editor edit=prefs.edit();
            edit.putBoolean("show_again",!accepted);
            edit.commit();
            dialog.dismiss();
        }
    });

    dialog.show();
}
