first of i'll assign id inner relativelayout:
<relativelayout android:layout_width="match_parent" android:layout_height="match_parent" android:id="@+id/container" > with can reference in code relativelayout, i'll add new field:
progressbar progressbar; relativelayout container; then onclick i'll hide container:
@override public void onclick(view view) { progressbar.setvisibility(view.visible); container.setvisibility(view.gone); ... and make visible when task done:
@override public void onresponse(string response) { try { jsonobject jsonobject = new jsonobject(response); boolean result = jsonobject.getboolean("register_result"); progressbar.setvisibility(view.gone); container.setvisibility(view.visible);... hope helps.
however, i'll not recommend user experience in app. there other mechanism notify user, check material design guidelines:

btw, tested code , works way mentioned you're expecting it. here's gist code, it's better if use snippets because renamed couple of variables:
