ScrollView嵌套RecyclerView冲突解决

1. ScrollView滑动不到顶部：
用这两句解决：
android:focusable=“true”
android:focusableInTouchMode=“true”

2.禁止recyclerview滑动
重写LinearLayout的canScrollVertical

 recruitMainJobslist.setLayoutManager(new LinearLayoutManager(recruitMainActivity.this) {            @Override            public boolean canScrollVertically() {                return false;            }        });

3.显示不全

import android.content.Context;import android.os.Build;import android.util.AttributeSet;import android.view.MotionEvent;import androidx.core.widget.NestedScrollView;/** * 解决scrollview与viewPager滑动冲突,解决gridRecyclerView-scrollView显示不全 *  拦截父类Interceptor */public class SlideListenerNestScrollview extends NestedScrollView {    public SlideListenerNestScrollview(Context context) {        super(context);    }    public SlideListenerNestScrollview(Context context, AttributeSet attrs) {        super(context, attrs);    }    public SlideListenerNestScrollview(Context context, AttributeSet attrs, int defStyleAttr) {        super(context, attrs, defStyleAttr);    }    @Override    protected void onScrollChanged(int l, int t, int oldl, int oldt) {        super.onScrollChanged(l, t, oldl, oldt);        if (mScrollChangeListener != null) {            mScrollChangeListener.onScroll(this, l, t);        }    }    private ScrollChangeListener mScrollChangeListener;    public void setmScrollChangeListener(ScrollChangeListener listener) {        mScrollChangeListener = listener;    }    public interface ScrollChangeListener {        void onScroll(SlideListenerNestScrollview slideListenerScrollview, int dx, int dy);    }    @Override    public void computeScroll() {        super.computeScroll();    }    private float mDownPosX = 0;    private float mDownPosY = 0;    @Override    public boolean onInterceptTouchEvent(MotionEvent ev) {        final float x = ev.getX();        final float y = ev.getY();        final int action = ev.getAction();        switch (action) {            case MotionEvent.ACTION_DOWN:                mDownPosX = x;                mDownPosY = y;                break;            case MotionEvent.ACTION_MOVE:                final float deltaX = Math.abs(x - mDownPosX);                final float deltaY = Math.abs(y - mDownPosY);                // 这里是够拦截的判断依据是左右滑动，读者可根据自己的逻辑进行是否拦截                if (deltaX > deltaY) {                    return false;                }        }        return super.onInterceptTouchEvent(ev);    }}

具体为啥，没看

4.scrollview recyclerView 去掉阴影：

android:overScrollMode=“never”
