Styling titleDivider in Dialog

Question

I am wondering how it is possible to get rid of (or change color) titleDivider in Dialog. It is a blue line below dialog title shown on honeycomb+ devices.

Answer 1

Here is how I resolved that (thanks to http://joerg-richter.fuyosoft.com/?p=181 ):

MyDialogBuilder.class

public class MyDialogBuilder extends android.app.AlertDialog.Builder {

public MyDialogBuilder(Context context) {
    super(context);
}

@NonNull
@Override
public android.app.AlertDialog create() {
    final android.app.AlertDialog alertDialog = super.create();

    alertDialog.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            int titleDividerId = getContext().getResources()
                    .getIdentifier("titleDivider", "id", "android");

            View titleDivider = alertDialog.findViewById(titleDividerId);
            if (titleDivider != null) {
                titleDivider.setBackgroundColor(getContext().getResources()
                        .getColor(R.color.alert_dialog_divider));
            }
        }
    });

    return alertDialog;
}
}
