如何在android的recyclerview中创建click listener？

我有一个“回收者”视图，其中包含列表中的一些项目，并且在单个项目中包含一个按钮。我想对按钮单击特定项执行一些操作我实现了回收器视图适配器，但不想在按钮单击适配器中实现代码我想在包含回收器视图实现的fragmenr中执行操作。我该怎么做

适配器的代码

 public class ViewHolder extends RecyclerView.ViewHolder {
    TextView m_premiumText, m_getDealText;

    public ViewHolder(View itemView) {
        super(itemView);
        m_premiumText = (TextView) itemView.findViewById(R.id.tv_premiun_deals);
        m_getDealText = (TextView) itemView.findViewById(R.id.tv_get_deals);

        m_getDealText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(mContext,"clicked"+getAdapterPosition(),Toast.LENGTH_LONG).show();
            }
        });
    }
}

回收器视图代码

 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    mContext = getActivity();
    main = inflater.inflate(R.layout.reward_premium_deals, container, false);
    findViewById();
    initControls();
    return main;
}


public void findViewById() {
    m_premiumList = (RecyclerView) main.findViewById(R.id.premium_list);
    m_layoutManager = new LinearLayoutManager(mContext);
    m_premiumList.setLayoutManager(m_layoutManager);

}

public void initControls() {
    premiumNames = getResources().getStringArray(R.array.premium_deals_title);
    m_premiumDealsAdapter = new CPremiumDealsAdapter(mContext, premiumNames);
    m_premiumList.setAdapter(m_premiumDealsAdapter);

    /*here i want button click action*/


}

在这些情况下，您必须使用侦听器或回调，并通过构造函数将其发送到回收器视图适配器

首先创建一个新接口用作回调。然后在片段中实现该接口，然后将片段（this）作为侦听器发送到适配器。然后，您可以从您的recycler view实例调用该操作。

由此，我在我的

活动
类中的
片段
中实现了recycler view项

接口类：

public interface RecyclerViewClickListener {
    void onClick(View view, int position);
    void onLongClick(View view, int position);
}


RecyclerViewTouchListener类：

public class RecyclerViewTouchListener implements RecyclerView.OnItemTouchListener {
private GestureDetector gestureDetector;
private RecyclerViewClickListener recyclerViewClickListener;

public RecyclerViewTouchListener(Context context, final RecyclerView recyclerView, final RecyclerViewClickListener recyclerViewClickListener1) {
    recyclerViewClickListener = recyclerViewClickListener1;
    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 && recyclerViewClickListener1 != null){
                recyclerViewClickListener.onLongClick(child, recyclerView.getChildLayoutPosition(child));
            }
        }
    });
}

@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
    View child = rv.findChildViewUnder(e.getX(), e.getY());
    if (child != null && recyclerViewClickListener != null && gestureDetector.onTouchEvent(e)){
        recyclerViewClickListener.onClick(child, rv.getChildLayoutPosition(child));
    }
    return false;
}

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

}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}
}


现在，在
片段
或
活动
类中，您必须在其中设置回收器视图活动：

recyclerView.setAdapter(your_adapter_class_object);
recyclerView.addOnItemTouchListener(new RecyclerViewTouchListener(this, recyclerView, new RecyclerViewClickListener() {
    @Override
    public void onClick(View view, int position) {
        Loge("Item","Click");
    }

    @Override
    public void onLongClick(View view, int position) {
        Loge("Item","Long Click");
    }
}));
