位置搜索ItemClick arraylist

如何解决位置搜索ItemClick arraylist

晚上好， 我正在创建一个关于我所在国家/地区的交通法规的应用程序，单击任何单元格时带有 RecyclerView 和 SearchView 的 Activity 为我带来了一个包含所选单元格信息的新意图，但是当搜索某个单词时，单击从位置 185 返回项目所需选项从位置 0 返回单元格信息，按照我的代码寻求帮助，是否不应该重置 onCLick 位置并进行新计数？ 我该如何解决这个问题？ 谢谢。

Item 185 after the research.

Information obtained from position 0 and not from 185.

AdapterEnquadramento.java

RecyclerItemClickListener

 private OnItemClickListener mListener;

        public boolean onSingleTapUp(MotionEvent e) {
            return true;
        }

        @Override
        public void onLongPress(MotionEvent e) {
            View child = recyclerView.findChildViewUnder(e.getX(),e.getY());
            if (child != null && mListener != null) {
                mListener.onLongItemClick(child,recyclerView.getChildAdapterPosition(child));
            }
        }
    });
}

@Override public boolean onInterceptTouchEvent(RecyclerView view,MotionEvent e) {
    View childView = view.findChildViewUnder(e.getX(),e.getY());
    if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
        mListener.onItemClick(childView,view.getChildAdapterPosition(childView));
        return true;
    }
    return false;
}

@Override public void onTouchEvent(RecyclerView view,MotionEvent motionEvent) { }

@Override
public void onRequestDisallowInterceptTouchEvent (boolean disallowIntercept){}

解决方法

我认为您不需要使用 onItemTouchListener 来处理 recyclerview 项目单击事件。 在您的适配器中，您可以直接在适配器中处理点击，如下所示：

float

请注意，我不测试此代码，但上述实现基于您在问题中的原始代码。请相应调整。
