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();
    }
}
