android - DialogFragment ~ 部分可见的对话框按钮

Question

我正在设计一个自定义对话框(使用 DialogFragment)，它会提示允许用户选择日期的日历 View 。显示对话框，但“确定”和“取消”仅部分可见。 Here is the screenshot for your reference.

这是我自定义的dialogfragment类

public class GetDateDialogFragment extends DialogFragment implements android.content.DialogInterface.OnClickListener {

@Override   
public Dialog onCreateDialog(Bundle savedInstanceState)
{
    LayoutInflater inflater = getActivity().getLayoutInflater();        
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    View calendarView = inflater.inflate(R.layout.activity_datepicker, null);
    calendarView.findViewById(R.id.btnOk).setVisibility(View.INVISIBLE);
    calendarView.findViewById(R.id.btnCancel).setVisibility(View.INVISIBLE);
    builder.setView(calendarView);      

    AlertDialog dialog = builder.setTitle(R.string.datetitle).setMessage("Please enter Date")
            .setPositiveButton("OK", this).setNegativeButton("Cancel", null).create();
    dialog.show();


    dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT, 600);       

    //position the buttons
    //Button positiveButton = dialog.getButton(DialogInterface.BUTTON_POSITIVE);
    //positiveButton.setY(positiveButton.getY()-100);

    //Button negativeButton = dialog.getButton(DialogInterface.BUTTON_NEGATIVE);
    //negativeButton.setY(negativeButton.getY()-100);

    return dialog;
}

请在下面找到布局 activity_datepicker.xml 的代码

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"
android:layout_height="250dp"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >

<CalendarView
    android:id="@+id/calendarView"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:scrollbarStyle="insideOverlay"
    android:scrollbars="vertical" />

<Button
    android:id="@+id/btnOk"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="false"
    android:layout_alignRight="@id/calendarView"
    android:text="@string/btnOk" />

<Button
    android:id="@+id/btnCancel"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@id/calendarView"
    android:layout_alignParentBottom="true"
    android:text="@string/btnCancel" />

尝试将 ok cacel 按钮的可见性设置为消失而不是不可见

LayoutInflater inflater = this.getLayoutInflater();
        AlertDialog.Builder builder = new AlertDialog.Builder(this);

        View calendarView = inflater
                .inflate(R.layout.activity_datepicker, null);
        calendarView.findViewById(R.id.btnOk).setVisibility(View.GONE);
        calendarView.findViewById(R.id.btnCancel).setVisibility(View.GONE);
        builder.setView(calendarView);

        AlertDialog dialog = builder.setTitle("dfd")
                .setMessage("Please enter Date").setPositiveButton("OK", null)
                .setNegativeButton("Cancel", null).create();
        dialog.show();

        dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT,
                LayoutParams.WRAP_CONTENT);
