问题
As far as I know, there are components ViewPager and ActionBar can support "tab navigation" mode but they don't have intermediate tab indicator between the tabs, just only positioning below a tab TextView.
How the Google Play app implemented this feature: POSITIONING linked with transition ?
回答1:
You can achieve this by implementing android:actionBarTabStyle using ActionBarSherlock library.
Update:
I don't have idea exactly about this, but hope you know Android team has integrated the same pattern in I/O 2013 Android app and it will open sourced soon.
Update 2:
I just came across one library which can fulfill your requirement, check this: https://github.com/astuetz/PagerSlidingTabStrip
