我正在尝试处理 Recycler View 中的触摸事件-:

class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {

        private ClickListener clickListener;
        private GestureDetector gestureDetector;

        public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final ClickListener clickListener){

            this.clickListener = clickListener;
            gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener(){
                @Override
                public boolean onSingleTapUp(MotionEvent e) {
                    return true;
                }

                @Override
                public void onLongPress(MotionEvent e) {
                   View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
                    if(child!=null && clickListener!=null)
                    {
                        clickListener.onLongClick(child, recyclerView.getChildPosition(child));
                        Log.i("TAG", "Radhe handling LongPress ");
                    }
                }
            });
        }

        @Override
        public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {

            View child = rv.findChildViewUnder(e.getX(), e.getY());
            if(child!=null && clickListener!=null && gestureDetector.onTouchEvent(e));
            {
                clickListener.onClick(child, rv.getChildPosition(child));
            }
            return false;
        }

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

        }

        @Override
        public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

        }

    }

    public static interface ClickListener{
        public void onClick(View view, int position);
        public void onLongClick(View view, int position);

    }

我还有以下代码-:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View layout = inflater.inflate(R.layout.fragment_navigation_drawer, container, false);
        recyclerView = (RecyclerView) layout.findViewById(R.id.drawerList);
        filterAdapter = new FilterAdapter(getActivity(), getData());
        recyclerView.setAdapter(filterAdapter);
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
        recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getActivity(), recyclerView, new ClickListener() {
            @Override
            public void onClick(View view, int position) {
                Log.i("TAG", "Radhe child Clicked ");
                Toast.makeText(getActivity(),"CLick",Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onLongClick(View view, int position) {
                Log.i("TAG", "Radhe child Long Clicked ");
                Toast.makeText(getActivity(),"Long CLick",Toast.LENGTH_SHORT).show();
            }
        }));


        return layout;
    }

现在当我运行它时 -: 和

android - 在 Recyclerview 中多次调用 onClick-LMLPHP

有人能告诉为什么会这样吗?我不知道这是什么原因。提前致谢。

最佳答案

我通常在 适配器 中处理点击事件,并通过如下界面与 fragment/Activity 交互。

在您的适配器的 onBindViewHolder 中;

viewHolder.mView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mListener.onItemClicked(holder.aValue);
    }
});

而 mListener 是一个接口(interface)
public interface IclickListener<T> {

    void onItemClicked(T object);

}

关于android - 在 Recyclerview 中多次调用 onClick,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/34510215/
