How to change background color of the button in DatePickerDialog?

Question

In my fragment I create a DatepickerDialog. Now I want to change the background color of the buttons programmatically. How can I do that?

Answer 1

You can get the Button from Dialog and modify it attributes using getButton(). See the example below. Get the button after calling .show(), otherwise it will give a null.

final Calendar c = Calendar.getInstance();
        int mYear = c.get(Calendar.YEAR);
        int  mMonth = c.get(Calendar.MONTH);
        int mDay = c.get(Calendar.DAY_OF_MONTH);
        DatePickerDialog datePickerDialog = new DatePickerDialog(ConstarintsActivity.this,
                (view, year, monthOfYear, dayOfMonth) -> {
                }, mYear, mMonth, mDay);
        datePickerDialog.show();
        datePickerDialog.getButton(DatePickerDialog.BUTTON_NEGATIVE).setTextColor(Color.GREEN);
