MyCustomDialogFragment总是 Package 它的内容，并且不像Alertdialog那样保持最小宽度。我如何设置宽度以作为标准Android对话框响应？
下面是我调用来显示对话框的函数：

private void displayDialogEdit(String title, String edit,
MyCustomEditDialog.MyCustomEditDialogListener listener, boolean onlyNumbers){
            MyCustomEditDialog dialog = MyCustomEditDialog.newInstance(title, edit, onlyNumbers);
            dialog.setInterface(listener);
            dialog.show(getSupportFragmentManager(), "edit");
        }

这是我的自定义对话框片段。

public class MyCustomEditDialog extends DialogFragment {

    private MyCustomEditDialog.MyCustomEditDialogListener mInterface;

    public static MyCustomEditDialog newInstance(String title, String editText, boolean onlyNumbers){
        MyCustomEditDialog dialog = new MyCustomEditDialog();
        Bundle args = new Bundle();
        args.putString("title", title);
        args.putString("edit", editText);
        args.putBoolean("numbers", onlyNumbers);
        dialog.setArguments(args);
        return dialog;
    }

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

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.fragment_edit_dialog, container);

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

//        Bundle args = getArguments();
//
//        boolean numbers = args.getBoolean("numbers");
//
//        TextView txt = (TextView)v.findViewById(R.id.title);
//        txt.setText(args.getString("title"));
//
//        final EditText edit = (EditText) v.findViewById(R.id.editText);
//        edit.setText(args.getString("edit"));
//
//        if (numbers) edit.setInputType(InputType.TYPE_CLASS_NUMBER);
//
//        Button btn = (Button)v.findViewById(R.id.save);
//
//        btn.setOnClickListener(new View.OnClickListener() {
//            @Override public void onClick(View view) {
//                if (mInterface!=null) mInterface.customDialogOnClick(edit.getText().toString());
//            }
//        });
//
//        setCancelable(true);

        return v;
    }

    public void setInterface(MyCustomEditDialog.MyCustomEditDialogListener listener){
        this.mInterface = listener;
    }

    public interface MyCustomEditDialogListener {
        void customDialogOnClick(String result);
    }

}

这是我的自定义对话框布局

<?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="wrap_content">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingStart="@dimen/activity_horizontal_margin"
        android:paddingEnd="@dimen/activity_horizontal_margin"
        android:gravity="center_horizontal"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:textColor="@color/blue_dark"
        android:textStyle="bold"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Medium Text"
        android:layout_marginBottom="10dp"
        android:id="@+id/title"
        android:layout_gravity="center_horizontal" />

    <EditText
        android:layout_marginStart="@dimen/activity_horizontal_margin"
        android:layout_marginEnd="@dimen/activity_horizontal_margin"
        android:layout_marginBottom="10dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/editText"
        android:inputType="text"
        />

    <Button
        style="@style/btnBasic.blue"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/save"
        android:id="@+id/save" />

</LinearLayout>
