Date Picker within DialogFragment
suggest changexml of the Dialog:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<DatePicker
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/datePicker"
android:layout_gravity="center_horizontal"
android:calendarViewShown="false"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="ACCEPT"
android:id="@+id/buttonAccept" />
</LinearLayout>
Dialog Class:
public class ChooseDate extends DialogFragment implements View.OnClickListener {
private DatePicker datePicker;
private Button acceptButton;
private boolean isDateSetted = false;
private int year;
private int month;
private int day;
private DateListener listener;
public interface DateListener {
onDateSelected(int year, int month, int day);
}
public ChooseDate(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.dialog_year_picker, container);
getDialog().setTitle(getResources().getString("TITLE"));
datePicker = (DatePicker) rootView.findViewById(R.id.datePicker);
acceptButton = (Button) rootView.findViewById(R.id.buttonAccept);
acceptButton.setOnClickListener(this);
if (isDateSetted) {
datePicker.updateDate(year, month, day);
}
return rootView;
}
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.buttonAccept:
int year = datePicker.getYear();
int month = datePicker.getMonth() + 1; // months start in 0
int day = datePicker.getDayOfMonth();
listener.onDateSelected(year, month, day);
break;
}
this.dismiss();
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
listener = (DateListener) context;
}
public void setDate(int year, int month, int day) {
this.year = year;
this.month = month;
this.day = day;
this.isDateSetted = true;
}
}
Activity calling the dialog:
public class MainActivity extends AppCompatActivity implements ChooseDate.DateListener{
private int year;
private int month;
private int day;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
private void showDateDialog();
}
private void showDateDialog(){
ChooseDate pickDialog = new ChooseDate();
// We could set a date
// pickDialog.setDate(23, 10, 2016);
pickDialog.show(getFragmentManager(), "");
}
@Override
onDateSelected(int year, int month, int day){
this.day = day;
this.month = month;
this.year = year;
}
}
