Question

Projemde kitaplık lapism/SearchView (https://github.com/lapism/SearchView) kullanıyorum. Ama sadece Android 5.0 üzerinde çalışma zamanı özel aşağıdaki olsun:

Lütfen herkes nasıl bu sorunu çözmek için herhangi bir fikir mi?

Answer 1

Bu sorunu düzeltmek için, SearchView ve AppBarLayout içeriklerini içeren XML dosyanızı güncellemeniz gerekir. android:stateListAnimator="@null", aşağıda gösterildiği gibi AppBarLayout numaranıza ekleyin. Bu android:stateListAnimator="@null" nitelik stateListAnimator sadece API düzeyinde 21. kullanılır Ama kütüphanenin kaynak kodunu kontrol ettik ve onu ayarlamaya çalıştığında o SearchBehavior sınıfta çöküyor konusunda uyararak gösterir

<android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:stateListAnimator="@null"> 

mAppBarLayout.setStateListAnimator(null);

Bu konu android bileşenlerine daha ilişkilidir altında
