NestedScrollView中的Recycler視圖

Question

我在NestedScrollView中有幾個水平滾動的Recycler視圖。如何僅在回收站視圖中禁用垂直滾動並將此垂直滾動傳遞給父級NestedScrollView？

Answer 2

我說你設置的觸摸偵聽器RecyclerView，並檢測是否是水平或垂直滾動​​。水平時返回true，垂直時返回false。

RecyclerView rv = findViewById(R.id.recyclerView); 
rv.setOnTouchListener(new View.OnTouchListener { 
    public boolean onTouch(View v, MotionEvent event) { 
     // your logic here 
    } 
}); 

參考 - View.OnTouchListener
