ScrollView嵌套RecyclerView时滑动出现的卡顿解决方案

问题现象:

一个界面有多个RecyclerView或者其他超过一屏显示的一些内容时,就需要要上下滚动了,就会需要在外面嵌套一个ScrollView,但是滑动过程不是很顺畅,有卡顿的感觉。

解决方案:

禁止RecyclerView的滑动。

最简单便捷的方法就是
linearLayoutManager = new LinearLayoutManager(context) {
    @Override
    public boolean canScrollVertically() {
        return false;
    }
};

另外就是重写LayoutManager了,以Grid模式举例说明:

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();
    }
}
