如果對(duì)Android的事件分發(fā)不熟悉，可以看Android的事件分發(fā)

瀑布流

實(shí)現(xiàn)的功能：滑動(dòng)左邊的RecyclerView區(qū)域，左邊的RecyclerView滾動(dòng)；滑動(dòng)中間的RecyclerView上半部分區(qū)域，三個(gè)RecyclerView一起滾動(dòng)（聯(lián)動(dòng)），滑動(dòng)中間的RecyclerView下半部分區(qū)域，中間的RecyclerView滾動(dòng)；滑動(dòng)右邊的RecyclerView區(qū)域，右邊的RecyclerView滾動(dòng)

重寫onInterceptTouchEvent()方法，并返回true，攔截touch事件，在onTouchEvent()方法中，判斷touch事件的區(qū)域，如果滑動(dòng)的是左邊的RecyclerView區(qū)域，調(diào)用getChildAt(0).dispatchTouchEvent(event)將touch事件分發(fā)給左邊的RecyclerView；如果滑動(dòng)的是右邊的RecyclerView區(qū)域，將touch事件分發(fā)給右邊的RecyclerView；如果滑動(dòng)的是中間的RecyclerView上半部分區(qū)域，將touch事件分發(fā)給三個(gè)RecyclerView，從而實(shí)現(xiàn)三個(gè)RecyclerView的聯(lián)動(dòng)，如果滑動(dòng)的是中間的RecyclerView下半部分區(qū)域，則將touch事件分發(fā)給中間的RecyclerView
