[Abhishek-dev1602]

Please look at this issue and provide solution.The background is there but indicator gone.My code is
<me.relex.circleindicator.CircleIndicator2
android:id="@+id/recyclerViewIndicator"
android:layout_width="wrap_content"
android:layout_height="18dip"
app:ci_width="10dip"
app:ci_height="10dip"
android:layout_gravity="center"
app:ci_drawable_unselected="@drawable/gray_radius"
/>

This worked for me -

adapter.registerDataSetObserver(indicator.getDataSetObserver());
