Fragment中RecyclerView的使用解析，以及监听事件处理

package adapter; import android.content.Context; import android.provider.ContactsContract; import android.support.v7.widget.RecyclerView; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.TextView; import android.widget.Toast; import com.example.jack_lin.procurementservice.R; import java.util.ArrayList; import Entity.GoodsEntity; public class CollectRecycleAdapter extends RecyclerView.Adapter<CollectRecycleAdapter.myViewHodler> { private Context context; private ArrayList<GoodsEntity> goodsEntityList; //创建构造函数 public CollectRecycleAdapter(Context context, ArrayList<GoodsEntity> goodsEntityList) { //将传递过来的数据，赋值给本地变量 this.context = context;//上下文 this.goodsEntityList = goodsEntityList;//实体类数据ArrayList } /** * 创建viewhodler，相当于listview中getview中的创建view和viewhodler * * @param parent * @param viewType * @return */ @Override public myViewHodler onCreateViewHolder(ViewGroup parent, int viewType) { //创建自定义布局 View itemView = View.inflate(context, R.layout.item_layout, null); return new myViewHodler(itemView); } /** * 绑定数据，数据与view绑定 * * @param holder * @param position */ @Override public void onBindViewHolder(myViewHodler holder, int position) { //根据点击位置绑定数据 GoodsEntity data = goodsEntityList.get(position); // holder.mItemGoodsImg; holder.mItemGoodsName.setText(data.goodsName);//获取实体类中的name字段并设置 holder.mItemGoodsPrice.setText(data.goodsPrice);//获取实体类中的price字段并设置 } /** * 得到总条数 * * @return */ @Override public int getItemCount() { return goodsEntityList.size(); } //自定义viewhodler class myViewHodler extends RecyclerView.ViewHolder { private ImageView mItemGoodsImg; private TextView mItemGoodsName; private TextView mItemGoodsPrice; public myViewHodler(View itemView) { super(itemView); mItemGoodsImg = (ImageView) itemView.findViewById(R.id.item_goods_img); mItemGoodsName = (TextView) itemView.findViewById(R.id.item_goods_name); mItemGoodsPrice = (TextView) itemView.findViewById(R.id.item_goods_price); //点击事件放在adapter中使用，也可以写个接口在activity中调用 //方法一：在adapter中设置点击事件 itemView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //可以选择直接在本位置直接写业务处理 //Toast.makeText(context,"点击了xxx",Toast.LENGTH_SHORT).show(); //此处回传点击监听事件 if(onItemClickListener!=null){ onItemClickListener.OnItemClick(v, goodsEntityList.get(getLayoutPosition())); } } }); } } /** * 设置item的监听事件的接口 */ public interface OnItemClickListener { /** * 接口中的点击每一项的实现方法，参数自己定义 * * @param view 点击的item的视图 * @param data 点击的item的数据 */ public void OnItemClick(View view, GoodsEntity data); } //需要外部访问，所以需要设置set方法，方便调用 private OnItemClickListener onItemClickListener; public void setOnItemClickListener(OnItemClickListener onItemClickListener) { this.onItemClickListener = onItemClickListener; } }
