android - NestedScrollView 内的回收站视图

Question

我在 NestedScrollView 中有一些水平可滚动的回收器视图。如何仅禁用回收器视图中的垂直滚动并将此垂直触摸传递给父 NestedScrollView？

Answer 1

我会说你设置了一个触摸监听器RecyclerView并检测它是水平滚动还是垂直滚动。true水平时返回，false垂直时返回。

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

参考 - View.OnTouchListener
