DatePickerDialog,TimePickerDialog在某些机型上会连续返回两次结果

继承系统的dialog，重写onStop方法

class CustomTimePicker extends TimePickerDialog {
public CustomTimePicker(Context context,OnTimeSetListener callBack,int hourOfDay,int minute,boolean is24HourView) {
    super(context,callBack,hourOfDay,minute,is24HourView);
}

@Override
protected void onStop() {}
}

一样地，重写DatePickerDialog

class CustomDataPicker extends DatePickerDialog {
public CustomDataPicker(Context context,OnDateSetListener callBack,int year,int monthOfYear,int dayOfMonth) {
    super(context,year,monthOfYear,dayOfMonth);
}

@Override
protected void onStop() {}
}
