我已经创建了一个自定义TimePicker对话框，但是当我更改字段时，对话框的标题也会发生变化。这种情况不会发生在我尝试过的每部手机上。
运行 Android 5.1.1 的 OnePlus One 和运行 android 6.1 <的 LG Nexus 5 的标题保持不变/ strong>即可。当我在运行 android 5 的三星Galaxy 5 上进行尝试时，它确实会发生变化。
知道是什么导致了这个吗？
我的自定义Timepicker类。
public class CustomTimePickerDialog extends TimePickerDialog {
private static int MINUTE_PICKER_INTERVAL = 60;
private final static int HOUR_PICKER_INTERVAL = 1;
private static int HOUR_PICKER_MIN;
private static int HOUR_PICKER_MAX;
private TimePicker timePicker;
private final OnTimeSetListener callback;
public CustomTimePickerDialog(Context context, OnTimeSetListener callBack,
int hourOfDay, int minute, boolean is24HourView, int hourPickerMin, int hourPickerMax, int timedistribution) {
super(context, TimePickerDialog.THEME_HOLO_LIGHT, callBack, hourOfDay, minute / MINUTE_PICKER_INTERVAL,
is24HourView);
this.callback = callBack;
HOUR_PICKER_MIN = hourPickerMin;
HOUR_PICKER_MAX = hourPickerMax;
MINUTE_PICKER_INTERVAL = timedistribution;
this.setTitle(context.getString(R.string.insert_time));
}
@Override
public void onClick(DialogInterface dialog, int which) {
if (callback != null && timePicker != null) {
timePicker.clearFocus();
callback.onTimeSet(timePicker, timePicker.getCurrentHour(),
timePicker.getCurrentMinute() * MINUTE_PICKER_INTERVAL);
}
}

dismiss();

if (which == DialogInterface.BUTTON_NEGATIVE) {
}
}
});
try {

NumberPicker mHourSpinner = (NumberPicker) timePicker.findViewById(fieldHour.getInt(null));
mHourSpinner.setMinValue(HOUR_PICKER_MIN);
mHourSpinner.setMaxValue((HOUR_PICKER_MAX / HOUR_PICKER_INTERVAL) - 1);
List<String> displayedValuesHour = new ArrayList<String>();

我的方法叫它。
