PagerSlidingTabStrip, нет индикатора вообще

Question

Я использую https://github.com/astuetz/PagerSlidingTabStrip и viewpager.

Я добавил код, чтобы получить значки, работающие с селекторами, и теперь я не могу включить или увидеть индикатор , для атрибутов setIndicatorColor использовали атрибуты и методы xml и java, но, похоже, они не работают.

Answer 1

удалите pstsTabBackground.

<com.example.PagerSlidingTabStrip 
    android:id="@+id/tabs_strip" 
    android:layout_width="match_parent" 
    android:layout_height="48dip" 
    android:background="#ffffff" 
    app:pstsDividerColor="#00000000" 
    app:pstsIndicatorColor="#aa66cc" 
    app:pstsIndicatorHeight="5dp" 
    app:pstsTabPaddingLeftRight="20dp" 
    app:pstsTextAllCaps="false" 
    app:pstsUnderlineColor="#ffffff" />
