I want a date picker to show only Month and Year. I've customized the Date Picker to do so i.e., to remove 'day' field from the picker,but in Android Lollipop Am getting picker with Day, Month and Year. Following is my piece of code. Please help me to know the problem. Thanks in advance.
try {
Field f[] = mDatePicker.getClass().getDeclaredFields();
for (Field field : f) {
if (field.getName().equals("mDaySpinner") || field.getName().equals("mDayPicker")) {
field.setAccessible(true);
Object dayPicker = new Object();
dayPicker = field.get(mDatePicker);
((View) dayPicker).setVisibility(View.GONE);
}
}
} catch (SecurityException e) {
} catch (IllegalArgumentException e) {
} catch (IllegalAccessException e) {
}
Using reflection to find and hide UI elements is not really a great practice. In your case, it stopped working in lollipop because the mDaySpinner
is now contained in an internal private static DatePickerSpinngerDelegate
class within the DatePicker
class.
I would recommend going through the view hierarchy to find and hide the day spinner element instead. I wrote the following code that works in lollipop:
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
int daySpinnerId = Resources.getSystem().getIdentifier("day", "id", "android");
if (daySpinnerId != 0) {
View daySpinner = datePicker.findViewById(daySpinnerId);
if (daySpinner != null) {
daySpinner.setVisibility(View.GONE);
}
}
}
