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;/** * 项目名称：HelloWorld * Created by xcl on 2016-03-02. */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();    }}
