Android DatePicker change to only Month and Year
As i recently stumbled across this problem myself, i tested multiple solutions from this post and similar questions on Stackoverflow.
Unfortunately i found no working solution especially for Android 5+
I ended up with implementing my own simple DialogFragment embedding two NumberPickers. This should be compatible with all versions from 3.0 and upwards.
Here is the code:
public class MonthYearPickerDialog extends DialogFragment {
private static final int MAX_YEAR = 2099;
private DatePickerDialog.OnDateSetListener listener;
public void setListener(DatePickerDialog.OnDateSetListener listener) {
this.listener = listener;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
Calendar cal = Calendar.getInstance();
View dialog = inflater.inflate(R.layout.date_picker_dialog, null);
final NumberPicker monthPicker = (NumberPicker) dialog.findViewById(R.id.picker_month);
final NumberPicker yearPicker = (NumberPicker) dialog.findViewById(R.id.picker_year);
monthPicker.setMinValue(0);
monthPicker.setMaxValue(11);
monthPicker.setValue(cal.get(Calendar.MONTH));
int year = cal.get(Calendar.YEAR);
yearPicker.setMinValue(year);
yearPicker.setMaxValue(MAX_YEAR);
yearPicker.setValue(year);
builder.setView(dialog)
// Add action buttons
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
listener.onDateSet(null, yearPicker.getValue(), monthPicker.getValue(), 0);
}
})
.setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
MonthYearPickerDialog.this.getDialog().cancel();
}
});
return builder.create();
}
}
And the layout
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:orientation="horizontal">
<NumberPicker
android:id="@+id/picker_month"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="20dp"
android:layout_marginRight="20dp">
</NumberPicker>
<NumberPicker
android:id="@+id/picker_year"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</NumberPicker>
</LinearLayout>
</LinearLayout>
To show the layout use:
MonthYearPickerDialog pd = new MonthYearPickerDialog();
pd.setListener(this);
pd.show(getFragmentManager(), "MonthYearPickerDialog");
I don't recommend using Reflection to do this kind of thing.
There is a simpler and more pretty way to do so:
((ViewGroup) datePickerDialog.getDatePicker()).findViewById(Resources.getSystem().getIdentifier("day", "id", "android")).setVisibility(View.GONE);
Be aware that .getDatePicker()
method from DatePickerDialog
works on API LEVEL >= 11
.
In addition it does not work on API LEVEL >= 21.
Try the following code. It will show a DatePicker
with only the year and month (without day)
private DatePickerDialog createDialogWithoutDateField() {
DatePickerDialog dpd = new DatePickerDialog(this, null, 2014, 1, 24);
try {
java.lang.reflect.Field[] datePickerDialogFields = dpd.getClass().getDeclaredFields();
for (java.lang.reflect.Field datePickerDialogField : datePickerDialogFields) {
if (datePickerDialogField.getName().equals("mDatePicker")) {
datePickerDialogField.setAccessible(true);
DatePicker datePicker = (DatePicker) datePickerDialogField.get(dpd);
java.lang.reflect.Field[] datePickerFields = datePickerDialogField.getType().getDeclaredFields();
for (java.lang.reflect.Field datePickerField : datePickerFields) {
Log.i("test", datePickerField.getName());
if ("mDaySpinner".equals(datePickerField.getName())) {
datePickerField.setAccessible(true);
Object dayPicker = datePickerField.get(datePicker);
((View) dayPicker).setVisibility(View.GONE);
}
}
}
}
}
catch (Exception ex) {
}
return dpd;
}
This method returns a date picker dialog. So , in your button's onClick
method add the following code to display your dialog.
createDialogWithoutDateField().show();
