更改TimePickerDialog的主题以使用AppTheme

我TimePickerDialog使用developer.android.com中给出的以下代码实现了:

public static class TimePickerFragment extends DialogFragment
                        implements TimePickerDialog.OnTimeSetListener {

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current time as the default values for the picker
    final Calendar c = Calendar.getInstance();
    int hour = c.get(Calendar.HOUR_OF_DAY);
    int minute = c.get(Calendar.MINUTE);

    // Create a new instance of TimePickerDialog and return it
    return new TimePickerDialog(getActivity(), this, hour, minute,
            DateFormat.is24HourFormat(getActivity()));
}

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
    // Do something with the time chosen by the user
}

}

我得到一个像这样的对话框:

我想改变主题,TimePickerDialog以AppTheme扩展AppCompat主题.当我使用其他构造函数时,一些人说,主题有效,但是Dialog全屏.我用的代码是:

// Create a new instance of TimePickerDialog and return it
        return new TimePickerDialog(getActivity(), R.style.AppTheme, this, hour, minute,
                DateFormat.is24HourFormat(getActivity()));

我明白了:

我该怎么做？- 我希望Dialog保持不变,但只改变强调色.谢谢!

你必须使用Theme.AppCompat.Light.DialogasParent Theme

你需要定义Dialog主题styles.xml.

然后像这样使用它:

// Create a new instance of TimePickerDialog and return it
return new TimePickerDialog(getActivity(), R.style.DialogTheme, this, hour, minute,
DateFormat.is24HourFormat(getActivity()));

我希望它对你有所帮助.
