Question

我正在使用产品的回收商视图。我想在回收商项目点击上显示产品描述。

我还在recyclerview行上放了一个按钮和复选框（收藏夹）。

现在我需要获得所有点击事件，这意味着我想要recyclelerview项目点击和子控件点击。

我的布局如下：

RecyclerView Touch事件

productRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
                @Override
                public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
                    final int action = e.getAction();
                    final int actionMasked = action & MotionEvent.ACTION_MASK;
                    if (actionMasked == MotionEvent.ACTION_DOWN) {
                        return false;
                    } else if (actionMasked == MotionEvent.ACTION_UP) {
                        HomeActivity.productclicked = (productDatas.get
                                (2));
                        HomeActivity.loadView(new SingleProductFragment(), "SingleProduct");
                        return false; //intercepted by the viewgroup and passed down to child
                    }
                    return false;

                }

                @Override
                public void onTouchEvent(RecyclerView rv, MotionEvent e) {

                }

                @Override
                public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

                }
            });

在适配器中添加到购物车按钮单击

viewHolder.cart_action.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    UserCart.addProductToCart(Integer.parseInt(view.getTag().toString()));
                    HomeActivity.increaseCartCount();
                }
            });

如果我没有在recyclerview上实现touchlistener，那么每个按钮都会起作用，否则它就无法工作。

基本上我想知道如何实施点击recyclelerview项目及其子项

有关我还在RecyclerView上使用Scroll Listener的信息。但我认为这对单击事件没有影响
