Question

我已通过DatePicker中的ImageView实施了Fragment。

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current date as the default date in the picker
    final Calendar c = Calendar.getInstance();
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);

    // Create a new instance of DatePickerDialog and return it
    return new DatePickerDialog(getActivity(), this, year, month, day);
}

// Called when the user presses "OK" on the DatePicker
@Override
public void onDateSet(android.widget.DatePicker datePicker, int i, int i1, int i2) {
    // Do something with the date chosen by the user
    String date = datePicker.getDayOfMonth() + "-" + datePicker.getMonth() + "-" + datePicker.getYear();       
}

我希望在我的调用Fragment中找到一个日期选择，调用DatePicker就像这样：

public class APD extends Fragment {

  [...]
   public void showDatePickerDialog() {
       DatePicker datePicker = new DatePicker();
       datePicker.show(getActivity().getSupportFragmentManager(), "datePicker");
   }

   calendar_image.setOnClickListener(new View.OnClickListener() {
           @Override
              public void onClick(View view) {
               showDatePickerDialog();
           }
       });
   [...]
}

如何实现？

您可以直接在片段上捕捉日期...请参阅此代码
