В моем приложении у меня есть вкладка, и я использую ActivityGroup для загрузки содержимого на каждую вкладку, как показано ниже.Android: DatePicker не работает внутри Activity
public class FirstGroup extends ActivityGroup {
// Keep this in a static variable to make it accessible for all the nesten activities, lets them manipulate the view
public static FirstGroup group;
// Need to keep track of the history if you want the back-button to work properly, don't use this if your activities requires a lot of memory.
private ArrayList<View> history;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.history = new ArrayList<View>();
group = this;
// Start the root activity withing the group and get its view
View view = getLocalActivityManager().startActivity("FlightsActivity", new
Intent(this,FlightsActivity.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP))
.getDecorView();
// Replace the view of this ActivityGroup
replaceView(view);
}
public void replaceView(View v) {
// Adds the old one to history
history.add(v);
// Changes this Groups View to the new View.
setContentView(v);
}
у меня есть изображение внутри класса FlightsActivity деятельности и на события OnClick образа мне нужна DatePicker быть displayed.I написал код, что и он работал хорошо, когда я был непосредственно указав FlightsActivity как содержание вкладки, а не загружая его через ActivityGroup.But теперь я получаю сообщение об ошибке

Ниже мой код для реализации DatePicker:
mPickDate = (ImageView) findViewById(R.id.pickDate);
mPickDate.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showDialog(DATE_DIALOG_ID);
}
});
@Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this,
mDateSetListener,
mYear, mMonth, mDay);
case DATE_DIALOG_ID_RETURN:
return new DatePickerDialog(this,
mDateSetListenerreturn,
mYear, mMonth, mDay);
}
return null;
}
// updates the date in the TextView
private void updateDisplay(TextView mDateDisplay) {
mDateDisplay.setText(
new StringBuilder()
// Month is 0 based so add 1
.append(mDay).append("-")
.append(mMonth + 1).append("-")
.append(mYear).append("")
);
}
private DatePickerDialog.OnDateSetListener mDateSetListener =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay(mDateDisplay);
}
};
private DatePickerDialog.OnDateSetListener mDateSetListenerreturn =
new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear = year;
mMonth = monthOfYear;
mDay = dayOfMonth;
updateDisplay(mDateDisplayreturn);
}
};
