RecyclerView的使用（包含点击事件）

adpater的代码：

<pre name="code" class="java">import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import com.augur.widgetdemo.Interface.OnRecyclerViewItemClickListener;
import com.augur.widgetdemo.Interface.OnRecyclerViewItemLongClickListener;
import com.augur.widgetdemo.R;

import java.util.List;

public class RecycleViewAdapter extends RecyclerView.Adapter<RecycleViewAdapter.MyViewHolder> {

    private Context mContext;
    private List<String> mData;
 private OnRecyclerViewItemClickListener mOnRecyclerViewItemClickListener;
    private OnRecyclerViewItemLongClickListener mOnRecyclerViewItemLongClickListener;
    //data是我们传递过来的数据
    public RecycleViewAdapter(Context context,List<String> data){
        this.mContext = context;
        this.mData = data;
    }
    //方法重载，通过构造函数把两个listener传递进来
    public RecycleViewAdapter(Context context,List<String> data,OnRecyclerViewItemLongClickListener itemLongClickListener,OnRecyclerViewItemClickListener listener){
        this.mContext = context;
        this.mData = data;
        this.mOnRecyclerViewItemClickListener = listener;
        this.mOnRecyclerViewItemLongClickListener = itemLongClickListener;
    }


    //recycleview已经把viewholder封装好的，我们只需要创建一个viewholder。然后传递给他，它自己会去缓存视图
    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //创建一个viewholder并返回
        //缺少context，我们在构造函数中让上级传递过来
        View view = LayoutInflater.from(mContext).inflate(R.layout.recycleview_item,parent,false);
        MyViewHolder myViewHolder = new MyViewHolder(view,mOnRecyclerViewItemClickListener,mOnRecyclerViewItemLongClickListener);
        return myViewHolder;
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {

        //绑定视图
        holder.mImageView.setImageResource(R.mipmap.pic);
        holder.mTextView.setText(mData.get(position));
    }

    @Override
    public int getItemCount() {
        return mData.size();
    }



    public static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener,View.OnLongClickListener{

        private ImageView mImageView;
        private TextView mTextView;
        private OnRecyclerViewItemClickListener mOnRecyclerViewItemClickListener;
        private OnRecyclerViewItemLongClickListener mOnRecyclerViewItemLongClickListener;
        public MyViewHolder(View itemView,OnRecyclerViewItemClickListener listener,OnRecyclerViewItemLongClickListener longClickListener) {
            super(itemView);
            mImageView = (ImageView) itemView.findViewById(R.id.recycleview_item_pic);
            mTextView = (TextView) itemView.findViewById(R.id.recycleview_item_name);
            this.mOnRecyclerViewItemClickListener = listener;
            this.mOnRecyclerViewItemLongClickListener = longClickListener;
            itemView.setOnClickListener(this);
            itemView.setOnLongClickListener(this);
        }

        @Override
        public void onClick(View v) {
            if (mOnRecyclerViewItemClickListener!=null){
                mOnRecyclerViewItemClickListener.onItemClick(v,getPosition());
            }
        }

        @Override
        public boolean onLongClick(View v) {
            if (mOnRecyclerViewItemLongClickListener!=null){
                mOnRecyclerViewItemLongClickListener.onItemLongClick(v,getPosition());
            }
            return true;
        }
    }

}

两个接口的代码：

public interface OnRecyclerViewItemClickListener {
    //仿造Listview的点击事件，返回一个view和位置
        void onItemClick(View view,int position);

}

public interface OnRecyclerViewItemLongClickListener {
    void onItemLongClick(View view,int position);
}

最后是主程序代码：

public class RecycleViewActivity extends AppCompatActivity implements OnRecyclerViewItemClickListener,OnRecyclerViewItemLongClickListener{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_recycleaview);
        RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycleview);

        //给他设置LayoutManager，这里设置的线性布局
        //接下来演示使用RecycleView的神奇之处，只需要改动LayoutManager就可以获得不同的而不惧
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        //设置成表格布局，两列
        //recyclerView.setLayoutManager(new GridLayoutManager(this,2));
        //设置成瀑布流,现在这样看不出来效果，大家可以把数据源改成大小不一的图片试试效果
      //  recyclerView.setLayoutManager(new StaggeredGridLayoutManager(2,StaggeredGridLayoutManager.VERTICAL));
        //给RecycleView设置适配器

        List<String> data = new ArrayList<>();
        for (int i =0; i< 100; i++){
            data.add(i,"你的第"+i+"个好友");
        }
        //记住还要改这里
        RecycleViewAdapter adapter = new RecycleViewAdapter(this,data,this,this);
        recyclerView.setAdapter(adapter);

        //到这里，我们就完成了recyclerview点击事件的设置，现在测试一下

    }


    @Override
    public void onItemClick(View view, int position) {
        Toast.makeText(RecycleViewActivity.this, "第"+position+"个位置被点击", Toast.LENGTH_SHORT).show();
    }

    @Override
    public void onItemLongClick(View view, int position) {
        Toast.makeText(RecycleViewActivity.this, "第"+position+"个位置被长按", Toast.LENGTH_SHORT).show();
    }
}
