如何改变DialogFragment的大小

Question

我在我的Android应用程序中有一个dialogFragment，其中包含一些视图，如下图所示：

我试图更改它的大小，但没有成功，在Java类中，我尝试这样做：

getDialog().getWindow().setLayout(800,800); getDialog().setTitle("请告诉我们");

如您所见，以上是代码。

 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;
}

但什么都没有改变。

这是布局文件：

您可以尝试在onResume()方法中设置对话框片段的宽度和高度，如下所示：

例如：

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