Android: Change custom AlertDialog background

Question

dialog layout xml:

Answer 1

I had the same problem, I managed to fix it using a custom dialog like this:

public class CustomDialog extends Dialog {
    public CustomDialog(Context context, View view) {
        super(context);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(view);
        getWindow().getDecorView().setBackgroundResource(android.R.color.transparent);
    }
}
