DateickerDialog,TimePickerDialog修改EditText后无法获取实际值

如果使用了android:theme="@android:style/Theme.Light.NoTitleBar"[code]样式的DateickerDialog，那么显示年月日的地方是EditText，是可以编辑的。

但是，在大多数手机上面，该EditText被修改后立即点击确定。那么获取到的年月日还是之前的年月日，我们没能够获取到EditText修改后的实际数据。我们可以巧妙地通过主动触发焦点的改变，来使得DatePicker的年月日改变，那么这样我们再获取到的DatePicker的年月日，就是修改后的年月日。

如下所示：

manifest.xml

application:

android:theme="@android:style/Theme.Light.NoTitleBar"

activity:

String TAG = getClass().getSimpleName();DatePickerDialog datePickerDialog;int year = 1990,month = 0,day = 1;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);datePickerDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {@Overridepublic void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {int realYear = year;int realMonthOfYear = monthOfYear;int realDayOfMonth = dayOfMonth;Calendar cal = Calendar.getInstance();try{datePickerDialog.getDatePicker().requestFocus();Log.d(TAG, "DatePickerDialog   " + datePickerDialog.getDatePicker().getCalendarView().getDate());Calendar calendar = Calendar.getInstance();calendar.setTime(new Date(datePickerDialog.getDatePicker().getCalendarView().getDate()));realYear = calendar.get(Calendar.YEAR);realMonthOfYear = calendar.get(Calendar.MONTH);realDayOfMonth = calendar.get(Calendar.DAY_OF_MONTH);Log.d(TAG,"year is :"+year+ "\tmonth is :"+month+"\tday is :"+day

			  +"\nrealYear is => "+realYear+"\trealMonth is =>"+realMonthOfYear+"\trealDayis =>"+realDayOfMonth);}catch (Exception e){Log.d(TAG,"DatePickerDialog   "+e.toString());}}},year,month,day);datePickerDialog.show();

｝

运行后直接把年的位置输入1994（不要通过点击+-号改变数字），点击确定。

（部分手机没有此问题，因此部分手机会在点击确定的时候把焦点跳到下一个EditText去！）

输出结果如下：04-04 14:50:24.969 8896-8896 D/MainActivity: DatePickerDialog   75740700047704-04 14:50:24.970 8896-8896 D/MainActivity: year is :1990	month is :0	day is :1ealYear is => 1994	realMonth is =>0	realDayis =>1

同理，TimePickerDialog也如此，需要把焦点改变。

但是TimePickerDialog并不能直接获取到TimePicker，那么我们可以通过反射的方式实现。

new TimePickerDialog.OnTimeSetListener() {@Overridepublic void onTimeSet(TimePicker view,int hourOfDay, int minute) {int realHourOfDay = hourOfDay;int realMinute = minute;Log.d(TAG,"======================>");try {Field mTimePicker = timePicker.getClass().getDeclaredField("mTimePicker");mTimePicker.setAccessible(true);TimePicker timePicker = (TimePicker) (mTimePicker.get(timePicker));timePicker.requestFocus();realHourOfDay = timePicker.getCurrentHour();realMinute = timePicker.getCurrentMinute();

Log.d(TAG, "hourOfDay =>"+hourOfDay+"\t"+"minute =>"+minute+

			"\nrealHourOfDay=>" + timePicker.getCurrentHour() + " realMinute=>" + timePicker.getCurrentMinute());} catch (Exception e) {Log.e(TAG,e.toString());}}}
