<ratingbar android:id="@+id/ratingindicator" style="?android:attr/ratingbarstylesmall" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/restaurantpicimagelinearviewid" android:layout_centerhorizontal="true" /> any ideas !
in onpostexecute():
ratingbar ratingbar = (ratingbar)findviewbyid(r.id.ratingindicator); ratingbar.setenabled(false); ratingbar.setmax(5); // assume 5 max rating ratingbar.setrating(integer.parseint(arraylist.get(mainactivity.rating)));
