在 RecyclerView 上同时实现 OnItemClickListener 和 OnItemLongClickListener

Question

我想在我的 Recycler 视图上同时实现 OnItemClickListener 和 OnItemLongClickListener。我使用 Android 库 BRVAH 来设置适配器。

我期待 OnItemLongClickListener 的自定义声明，以便我可以将它放在我的（已经实现的）OnItemClickListener 上。

    mAdapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
        public void onItemClick(BaseQuicAdapter adapter, final View view, int position) {
        .....
        }
    });

你必须做两个接口来处理点击事件和长点击事件到recyclview的适配器中。

就像把下面的接口变成适配器类..

onItemClickListner onItemClickListner;
onItemLongClickListner onItemLongClickListner;

public void setOnItemLongClickListner(RecyclerViewAdpater.onItemLongClickListner onItemLongClickListner) {
    this.onItemLongClickListner = onItemLongClickListner;
}

public void setOnItemClickListner(RecyclerViewAdpater.onItemClickListner onItemClickListner) {
    this.onItemClickListner = onItemClickListner;
}

public interface onItemClickListner {
    void onClick(String str);//pass your object types.
}
public interface onItemLongClickListner{
    void onLongClick(String str);
}
@Override
public void onBindViewHolder(ItemViewHolder holder, int position) {
    String data = mStringList.get(position); // if you pass object of class then create that class object.
    holder.textView.setText(data);
    // below code handle click event on recycler view item.
    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            onItemClickListner.onClick(data);
        }
    });
    holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
            onItemLongClickListner.onLongClick("Hiii");
            return false;
        }
    });
}

然后在适配器定义和绑定到回收器视图之后定义回收器视图时在活动中然后获得两个点击事件，如下所示..

recyclerViewAdpater.setOnItemClickListner(new RecyclerViewAdpater.onItemClickListner() {
        @Override
        public void onClick(String str) {
            Toast.makeText(getApplicationContext(),"Value of Click"+str,Toast.LENGTH_SHORT).show();
        }
    });
    recyclerViewAdpater.setOnItemLongClickListner(new RecyclerViewAdpater.onItemLongClickListner() {
        @Override
        public void onLongClick(String str) {
            Toast.makeText(getApplicationContext(),"Value of Long Click"+str,Toast.LENGTH_SHORT).show();

        }
    });

您可以使用库的以下方法。

   /**
     * Register a callback to be invoked when an item in this RecyclerView has
     * been long clicked and held
     *
     * @param listener The callback that will run
     */
    public void setOnItemLongClickListener(OnItemLongClickListener listener) {
        mOnItemLongClickListener = listener;
    }

所以在你的代码中实现它

    mAdapter.setOnItemLongClickListener(new BaseQuickAdapter.OnItemLongClickListener() {
    boolean onItemLongClick(BaseQuickAdapter adapter, View view, int position) {
    .....
    }

进入你的适配器并找到 ViewHolder 类并编写以下代码

  public class MyViewHolder extends RecyclerView.ViewHolder{

        public MyViewHolder(View itemView) {
            super(itemView);

            itemView.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View view) {
                    //call onClick handler here  
                }
            });

            itemView.setOnLongClickListener(new OnLongClickListener() {
                @Override
                public boolean onLongClick(View view) {
                    //call onLongClick handler here                        //Here you will return true
                    return true;
                }
            });

        }
    }

然后创建两个类似的接口

 public interface OnMyLongClickListener{
        void onLongClick(int pos);
    }
    public interface OnMyClickClickListener{
        void onClick(int pos);
    }

在您的活动或片段类中实现这两个接口，然后在接收事件中调用这些接口方法
