You can use the Widget like slider tab indicator which is compatible with ViewPager in android.

Include the PagerSlidingTabStrip widget in your view. This should usually be placed adjacent to the ViewPager it represents.

<com.astuetz.viewpager.extensions.PagerSlidingTabStrip
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="48dip" />

In your onCreate method (or onCreateView for a fragment), bind the widget to the ViewPager.

 // Set the pager with an adapter
 ViewPager pager = (ViewPager) findViewById(R.id.pager);
 pager.setAdapter(new TestAdapter(getSupportFragmentManager()));
 // Bind the widget to the adapter
  PagerSlidingTabStrip tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
  tabs.setViewPager(pager);
