如何在DatePickerDialog中删除多余的空间(在Android M&N上看到)？

我在DatePickerDialog的右侧看到了一个额外的空间,仅在Android M& N版.在基于L的构建中没有观察到它.这是截图：

有人遇到过这个问题吗？

这是DatePickerFragment的实现：

public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

    public static DatePickerFragment newInstance(int day, int month, int year)
    {
        DatePickerFragment frag = new DatePickerFragment();
        Bundle args = new Bundle();
        args.putInt("day", day);
        args.putInt("month", month);
        args.putInt("year", year);
        frag.setArguments(args);
        return frag;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        int year = getArguments().getInt("year");
        int month = getArguments().getInt("month");
        int day = getArguments().getInt("day");
        DatePickerDialog datePickerDialog =new DatePickerDialog(getActivity(), this, year, month, day);
        datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
        return datePickerDialog;
    }

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)
    {
        try
        {
            DatePickerDialogListener listener = (DatePickerDialogListener)getActivity();
            listener.onFinishDatePickDialog(year, monthOfYear + 1, dayOfMonth);
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }
    }

    // 1. Defines the listener interface with a method passing back data result.
    public interface DatePickerDialogListener {
        void onFinishDatePickDialog(int year, int monthOfYear, int dayOfMonth);
    }

}

这里是样式表,它有一个android的组件：datePickerDialogTheme

    <style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="android:windowContentTransitions">true</item>
        <item name="colorControlNormal">@color/colorAccent</item>
        <item name="colorControlActivated">@color/colorAccent</item>
        <item name="colorControlHighlight">@color/colorAccent</item>
        <item name="textColorError">@android:color/holo_red_dark</item>
        <item name="android:timePickerDialogTheme">@style/AlertDialogCustom</item>
        <item name="android:datePickerDialogTheme">@style/AlertDialogCustom</item>
        <item name="android:alertDialogTheme">@style/AlertDialogCustom</item>
    </style>

    <style name="AlertDialogCustom" parent="android:Theme.Material.Light.Dialog.Alert">
        <item name="android:colorPrimary">@color/colorPrimary</item>
        <item name="android:colorAccent">@color/colorAccent</item>
    </style>

注意：如果我不使用样式来修改颜色,则不会出现此问题.

解决方法:

不要使用Theme.AppCompat.Light.Dialog.Alert,只需使用Theme.AppCompat.Light.Dialog即可.当你看里面时,

< style name =“Base.ThemeOverlay.AppCompat.Dialog.Alert”>
  < item name =“android：windowMinWidthMajor”> @ diem / abc_dialog_min_width_major< / item>
< item name =“andorid：windowMinWidthMinor”> @ dimen / abc_dialog_min_width_minor< / item>
&LT /风格&GT

风格有额外的尺寸修改,结果是不受欢迎的.
