关于recycler遇到的问题_corecycler-master出错-优快云博客

本文介绍了两种方法来禁用或限制Android应用中的RecyclerView滑动：一是通过自定义LayoutManager禁止滑动；二是通过拦截触摸事件阻止滑动。同时讨论了如何在scrollView中嵌套RecyclerView时仅允许scrollView滑动的方法。

1.//设置recyclerView不能点击
myLayoutManager.setScrollEnabled(false);
class MyLayoutManager extends LinearLayoutManager {
    private boolean isScrollEnabled = true;
    public MyLayoutManager(Context context) {
        super(context);
    }
    public MyLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }
    public MyLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }
    public void setScrollEnabled(boolean flag) {
        this.isScrollEnabled = flag;
    }
    @Override
    public boolean canScrollVertically() {
        //isScrollEnabled：recyclerview是否支持滑动
        //super.canScrollVertically()：是否为竖直方向滚动
        return isScrollEnabled && super.canScrollVertically();
    }
}

2.//屏蔽滑动事件

public class BanScrollview extends ScrollView {
private int downX;
    private int downY;
    private int mTouchSlop;

    public BanScrollview(Context context) {
super(context);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

public BanScrollview(Context context, AttributeSet attrs) {
super(context, attrs);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

public BanScrollview(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
        mTouchSlop = ViewConfiguration.get(context).getScaledTouchSlop();
    }

@Override
    public boolean onInterceptTouchEvent(MotionEvent e) {
int action = e.getAction();
        switch (action) {
case MotionEvent.ACTION_DOWN:
downX = (int) e.getRawX();
                downY = (int) e.getRawY();
                break;
            case MotionEvent.ACTION_MOVE:
int moveY = (int) e.getRawY();
                if (Math.abs(moveY - downY) > mTouchSlop) {
return true;
                }
        }
return super.onInterceptTouchEvent(e);
    }
}

3.scrollView中嵌套recyclery时，当界面显示有recyclerView的数据，这时recycler会有自己的滑动效果，怎么实现滑动的是scrollview呢？我在尝试添加footview
最后我是在recycler中加了RelativeLayout
