Images for AlertDialog buttons

Question

Is it possible to add drawables to the positive, negative and neutral buttons of an AlertDialog? If yes, then how?

Answer 1

Since onPrepareDialog is deprecated, you can use the onShowListener instead.

Also you should set the Drawable bounds or it will be placed far left.

Output of Code below

public class MyDialog extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        final AlertDialog dialog = new AlertDialog.Builder(getActivity())
                .setTitle("My Dialog")
                .setNegativeButton("Cancel", new OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // TODO Auto-generated method stub
                    }
                }).setPositiveButton("Play", new OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // TODO Auto-generated method stub
                    }
                }).create();
        dialog.setOnShowListener(new OnShowListener() {

            @Override
            public void onShow(DialogInterface dialogInterface) {
                Button button = dialog.getButton(AlertDialog.BUTTON_POSITIVE);

                // if you do the following it will be left aligned, doesn't look
                // correct
                // button.setCompoundDrawablesWithIntrinsicBounds(android.R.drawable.ic_media_play,
                // 0, 0, 0);

                Drawable drawable = getActivity().getResources().getDrawable(
                        android.R.drawable.ic_media_play);

                // set the bounds to place the drawable a bit right
                drawable.setBounds((int) (drawable.getIntrinsicWidth() * 0.5),
                        0, (int) (drawable.getIntrinsicWidth() * 1.5),
                        drawable.getIntrinsicHeight());
                button.setCompoundDrawables(drawable, null, null, null);

                // could modify the placement more here if desired
                // button.setCompoundDrawablePadding();
            }
        });
        return dialog;
    }
}
