Nestedscrollview 및 Recyclerview가있는 ViewPager와 저크가있는 로딩

Question

ViewPager과 NestedScrollView 및 RecyclerView을 사용했습니다. 모든 것은 잘 작동하고 있습니다. 리사이클 러 뷰가 먼저로드 된 다음, 페이저를 저크 (부드럽게 보이지 않음)로 볼 수 있고 화면이 좋지 않게 보이는 화면을로드하는 동안 예상대로 작동합니다.

지금 당장 디자인 쪽에서보기 호출기 용 어댑터를 설정하지 않았습니다. 뷰 페이저 나 recyclerview가 아닌 ​​데이터를 채우지 않았습니다.

Answer 1

마지막으로 나 자신과 대답을 얻었다!

사용자 정의 NestedScrollView을 구현했으며이 두 가지 방법을 오버라이드하고 매력처럼 작동합니다!

@Override 
public void requestChildFocus(View child, View focused) { 
    Log.d(getClass().getSimpleName(), "Request focus"); 

} 

@Override 
protected boolean onRequestFocusInDescendants(int direction, Rect previouslyFocusedRect) { 
    Log.d(getClass().getSimpleName(), "Request focus descendants"); 
    //return super.onRequestFocusInDescendants(direction, previouslyFocusedRect); 
    return false; 
}
