Android ScrollView里嵌套RecyclerView时,在RecyclerView上滑动时出现卡顿(冲突)的现象
最近在项目中遇到一个现象,一个界面有一个RecyclerView(GridView型的),外面套了一层ScrollView,通过ScrollView上下滚动,但是在滑动的时候如果是在RecyclerView的内容上滑动,这时会出现滑动卡顿,而如果是在其他内容上滑动时就可以很顺畅的滑下去。
这是RecyclerView和ScrollView的滑动事件冲突引起的,解决办法就是禁止RecyclerView的滑动事件.
解决办法:
方法一:
inearLayoutManager = new LinearLayoutManager(context) { @Override public boolean canScrollVertically() { return false; } };
方法二:
重写LayoutManager或者GridLayoutManager
public class ScrollGridLayoutManager extends GridLayoutManager { private boolean isScrollEnabled = true; public ScrollGridLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { super(context, attrs, defStyleAttr, defStyleRes); } public ScrollGridLayoutManager(Context context, int spanCount) { super(context, spanCount); } public ScrollGridLayoutManager(Context context, int spanCount, int orientation, boolean reverseLayout) { super(context, spanCount, orientation, reverseLayout); } public void setScrollEnabled(boolean flag) { this.isScrollEnabled = flag; } @Override public boolean canScrollVertically() { //Similarly you can customize "canScrollHorizontally()" for managing horizontal scroll return isScrollEnabled && super.canScrollVertically(); } }
