TabLayout will get empty Tab after upgrade design library to 22.2.1

  Google introduces the design library for making material design easier. so we reimplement the tab component by TabLayout. it's work perfectly in 22.2.0. but we get problem after upgrade the version to 22.2.1. the tab doesn't show up anymore(issue track).

  it's work on some place, but some one isn't. we couldn't figure out what is the right way to handle this. so we decide to rollback the version to 22.2.0.
