[CymChad/BaseRecyclerViewAdapterHelper]Recyclerview嵌套Recyclerview的外层Recyclerview的item点击事件问题

adapter.setOnItemClickListener((adapter, view, position) -> { Log.i("TAG", "setOnItemClickListener"); });

使用上面代码时点击蓝色框不起作用，只有点击蓝色框外部，红色框里面时才有效果。

而我使用 recyclerView.addOnItemTouchListener(new OnItemClickListener() { @Override public void onSimpleItemClick(BaseQuickAdapter adapter, View view, int position) { LogUtils.i("TAG", "onSimpleItemClick"); } });时，点击中间蓝色框有效果，但是点击事件又执行了两次。怎么破？

1. 嵌套点击事件， 内部提供了一个setNestChild() 属性，在父层Adapter内设置子recyclerview的id ，可参考Demo里面的嵌套事件的点击写法

@AllenCoder
写了个democe测试嵌套Recyclerview

 @Override
    protected void convert(BaseViewHolder helper, String item) {
        RecyclerView mRecyclerView = helper.getView(R.id.item_list);
        SecondAdapter adapter = new SecondAdapter();
        GridLayoutManager gridLayoutManager = new GridLayoutManager(mContext, 3);
        gridLayoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
        mRecyclerView.setLayoutManager(gridLayoutManager);
        mRecyclerView.setAdapter(adapter);

        List<String> mListData = new ArrayList<>();
        for (int i = 0; i < 5; i++) {
            mListData.add("dd");
        }
        adapter.setNewData(mListData);

        helper.setNestView(R.id.item_list);

        adapter.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
                Toast.makeText(mContext,position+"嵌套",Toast.LENGTH_SHORT).show();
            }
        });
    }

点击红框空白部分没有响应

请问楼主最后怎么解决的。。

同问

在item里面的Recyclerview上门覆盖一层透明的View，然后监听这层覆盖view的点击事件即可解决.

给子recycleView设置onTouch事件，并且设置子recycleView的点击监听事件：

  recyclerView.setOnTouchListener(new ChildTouchListener(this));
  recyclerView.setOnClickListener(v -> {
                //do.........
   });

  private class ChildTouchListener implements View.OnTouchListener{

    private float downX;
    private float downY;
    private float touchSlop;
    private View view;

    ChildTouchListener(View view){
        this.view = view;
        touchSlop = ViewConfiguration.get(view.getContext()).getScaledTouchSlop();
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getActionMasked()){
            case MotionEvent.ACTION_DOWN:
                downX = event.getX();
                downY = event.getY();
                break;
            case MotionEvent.ACTION_UP:
                if (Math.abs(event.getY() - downY) < touchSlop && Math.abs(event.getX() - downX) < touchSlop){
                    view.performClick();
                }
                break;
        }
        return false;
    }
}

//内层recyclerView设置属性：让外层recyclerView能接收到点击事件 recyclerView.suppressLayout(true); 内层添加该属性，亲测有效

4.0 版本是不是没有这个属性了？

亲测无效
