Change button color in AlertDialog

Question

How can I change the color of the button(s) in an AlertDialog in Android?

Answer 1

if you are using DialogFragment ( android.app.DialogFragment ) then you can overwrite onStart method to get handle of all the buttons (Positive, Negative and Neutral).

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    View eventEditDialogView = View.inflate(this.getActivity(), R.layout.event_edit_dialog,
                                            null);

    builder.setTitle(getLocalizedString("edit_event"))
            .setView(eventEditDialogView)
            .setPositiveButton(getLocalizedString("all_events"), new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                }
            })
            .setNegativeButton(getLocalizedString("this_event"), new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                }
            })
    return builder.create();
}

 @Override
    public void onStart() {
        super.onStart();
    Button positive = ((AlertDialog) getDialog()).getButton(AlertDialog.BUTTON_POSITIVE);
    positive.setTextColor(Color.BLACK);
    positive.setBackgroundColor(getResources().getColor(R.color.GrayBGColor));
}

All the above solutions will work with AlertDialog or Dialog created on same activity or Fragment but not on DialogFragment created separately.
