如下代码主要解决两个问题：
解决ViewPager嵌套垂直RecyclerView嵌套水平RecyclerView横向滑动到底后不滑动ViewPager
解决思路: 继承RecyclerView，重写dispatchTouchEvent，根据ACTION_MOVE的方向判断是否调用getParent().requestDisallowInterceptTouchEvent去阻止父view拦截点击事件
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
/*---解决垂ViewPager嵌套直RecyclerView嵌套水平RecyclerView横向滑动到底后不滑动ViewPager start ---*/
ViewParent parent =this;
while(!((parent = parent.getParent()) instanceof ViewPager));// 循环查找viewPager
parent.requestDisallowInterceptTouchEvent(true);
/*---解决垂ViewPager嵌套直RecyclerView嵌套水平RecyclerView横向滑动到底后不滑动ViewPager start ---*/
return super.dispatchTouchEvent(ev);
}
解决垂直RecyclerView嵌套水平RecyclerView横向滑动不流畅问题
解决思路：循环查找父亲View是否为ViewPager,如果是，则阻止父view拦截事件
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
/*--------解决垂直RecyclerView嵌套水平RecyclerView横向滑动不流畅问题 start --------*/
int x = (int) ev.getRawX();
int y = (int) ev.getRawY();
int dealtX = 0;
int dealtY = 0;
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
dealtX = 0;
dealtY = 0;
// 保证子View能够接收到Action_move事件
getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_MOVE:
dealtX += Math.abs(x - lastX);
dealtY += Math.abs(y - lastY);
// Log.i("dispatchTouchEvent", "dealtX:=" + dealtX);
// Log.i("dispatchTouchEvent", "dealtY:=" + dealtY);
// 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 (dealtX >= dealtY) {
getParent().requestDisallowInterceptTouchEvent(true);
} else {
getParent().requestDisallowInterceptTouchEvent(false);
}
lastX = x;
lastY = y;
break;
case MotionEvent.ACTION_CANCEL:
break;
case MotionEvent.ACTION_UP:
break;
}
/*--------解决垂直RecyclerView嵌套水平RecyclerView横向滑动不流畅问题 end --------*/
return super.dispatchTouchEvent(ev);
}
