My application needed two spinners appearing vertically parellel like a datepicker with date and month. I was trying to access the datepicker class object spinner, hide the year column and access the two columns. Can anyone help me on this.Thanks in advance.

What I have tried:

Field f[] = dp.getClass().getDeclaredFields();
//Field f[] = dp.getClass().getDeclaredField("mYearPicker");

for (Field field : f) {
Toast.makeText(getApplicationContext(), field.getName(), Toast.LENGTH_SHORT).show();

if (field.getName().equals("mYearPicker") || field.getName().equals("mYearSpinner")) {
field.setAccessible(true);
((View) field.get(this)).setVisibility(View.GONE);
}
}

Even this didnt work hiding the year column
