如何改变DialogFragment大小

Question

我有我的一些观点的Android应用程序dialogFragment，你可以在下面的图片中看到：

我尝试没有成功改变它的大小，在Java类我试图做到这一点： getDialog().getWindow().setLayout(800,800); getDialog().setTitle("Please tell us");，你可以在下面的代码中看到：

public View onCreateView (LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

    Log.d(TAG, "onCreateView(LayoutInflaterm ViewGroup, Bundle) - Ini "); 

    View view = inflater.inflate(R.layout.dialog_box_layout, container, false); 

    ageSpinner = (Spinner) view.findViewById(R.id.age_spinner_dialog); 
    ageSpinner.setSelected(false); 
    ageSpinner.setAdapter(populateAgeSpinner()); 
    ageSpinner.setOnItemSelectedListener(this); 

    radioDialogMale = (RadioButton) view.findViewById(R.id.radioDialogM); 
    radioDialogMale.setSelected(false); 
    radioDialogMale.setOnClickListener(this); 
    radioDialogFemale = (RadioButton) view.findViewById(R.id.radioDialogF); 
    radioDialogFemale.setSelected(false); 
    radioDialogFemale.setOnClickListener(this); 


    okButton = (Button) view.findViewById(R.id.dialog_ok); 
    okButton.setOnClickListener(this); 

    getDialog().getWindow().setLayout(800,800); 
    getDialog().setTitle("Please tell us"); 

    communicator = (LoginActivity) getActivity(); 

    setCancelable(false); 

    Log.d(TAG, "onCreateView(LayoutInflaterm ViewGroup, Bundle) - Fi "); 

    return view; 
} 

，但没有任何变化。

这里的布局文件：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#000">

    </RadioGroup> 

    /> 

    <Button 
     android:layout_width="wrap_content" 
     android:layout_height="30dp" 
     android:id="@+id/dialog_ok" 
     android:background="@color/com_facebook_button_send_background_color" 
     android:textColor="#FFF" 
     android:text="OK" 
     android:layout_below="@+id/radioGroup" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="25dp" /> 

</RelativeLayout> 

帮助请！

Answer 1

您可以尝试从onResume（）方法设置对话框片段的宽度和高度。如下图所示：

public void onResume() 
{ 
    super.onResume(); 
    Window window = getDialog().getWindow(); 
    window.setLayout(width, height); 
    window.setGravity(Gravity.CENTER); 
    //TODO: 
}
