Refresh contents of dialog

Question

I need to update a custom dialog content whenever that dialog is ready to be drawin. I am not sure this could be refreshed directly or if I need to close it first and re-ins

Answer 1

Get the view that the Dialog is using and [post]invalidate it.

Instead of Dialog.setContentView(int);

Do something like:

public class MyDialog {
        View v = null;

        public Dialog show(Context context) {
            Dialog d = new Dialog(context);
            v = LayoutInflater.from(context).inflate(R.layout.resource, null);
            d.setContentView(v);
            return d.show();
        }

        public void update() {
            v.invalidate();
        }
}
