Google Map with CollapsingToolbar ve NestedScrollView

Question

UBER gibi bir uygulama geliştiriyorum. Özel işaretleyicinin ilk kaydırılması harita üzerinde sorunsuz çalışıyordu. Bundan sonra, UBER gibi NestedScrollView ekledim. Ancak harita kaydırma hareketi AppBar Scrolling davranışıyla çakışıyor. Ne yapacağımı bilmiyorum, lütfen bana yardımcı olun.

buldum uzun aramadan sonra HomeFragment

googleMap.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() { 

      @Override 
      public void onCameraChange(CameraPosition arg0) { 
       // TODO Auto-generated method stub 
       if (!mMapIsTouched) { 
        // Show Outer layout 
        CommonMethods.getInstance().e("","User Is not touching MAP"); 
        googleMap.getUiSettings().setAllGesturesEnabled(true); 
       } 
       else{ 
        // Hide Outer Layout 
        CommonMethods.getInstance().e("", "User Is touching MAP"); 
        googleMap.getUiSettings().setAllGesturesEnabled(false);

      }

orada tasarım kütüphanesinde hata olduğunu ve bu bağlamda zaten reported

Onun sözü var

Bir AppBarLayout'taki kaydırılabilir kapsayıcılar hiç bir zaman resmi olarak destekli olmadı.

Bir sonraki sürümde, ihtiyacınız varsa sürüklemeyi devre dışı bırakmanıza olanak veren AppBarLayout.Behavior.DragCallback .

appbar düzen içeriğinde Bu DragCallback yöntem durdurma sürükleme etkisi ve NestedScrollView cazibe gibi çalışıyor.

AppBarLayout appBarLayout = (AppBarLayout) findViewById(R.id.appbar_layout); 
    CoordinatorLayout.LayoutParams params = 
      (CoordinatorLayout.LayoutParams) appBarLayout.getLayoutParams(); 
    AppBarLayout.Behavior behavior = new AppBarLayout.Behavior(); 
    behavior.setDragCallback(new AppBarLayout.Behavior.DragCallback() { 
     @Override 
     public boolean canDrag(AppBarLayout appBarLayout) { 
      return false; 
     } 
    });
