1.新建一个适配器继承自RecyclerView.Adapter

package aud.hik.com.audiorecordtool;
 
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
 
import java.util.List;
 
public class FileListAdapter extends RecyclerView.Adapter {
  private final String TAG = "FileListAdapter";
  private List mFileList = null;
  private OnItemClickListener mOnItemClickListener = null;
  static class ViewHolder extends RecyclerView.ViewHolder{
    TextView fileNameView;
 
    public ViewHolder(View view) {
      super(view);
      fileNameView = (TextView) view.findViewById(R.id.file_name);
    }
  }
 
  public FileListAdapter(List fileList) {
    this.mFileList = fileList;
  }
 
  //加载item 的布局 创建ViewHolder实例
  @Override
  public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item,parent,false);//加载view布局文件
    ViewHolder holder = new ViewHolder(view);
    return holder;
  }
 
  //对RecyclerView子项数据进行赋值
  @Override
  public void onBindViewHolder(ViewHolder holder, int position) {
    if(null == holder)
    {
      MyLog.LOGE(TAG,"Holder is null");
      return;
    }
    final String fileName= mFileList.get(position);
    MyLog.LOGI(TAG,"filename = "+fileName +"filenameview = "+holder.fileNameView);
    holder.fileNameView.setText(fileName);
 
    final int tempPosition = position;
 
    if(null != mOnItemClickListener)
    {
      holder.itemView.setOnClickListener( new View.OnClickListener() {
 
        @Override
        public void onClick(View v) {
          mOnItemClickListener.onClickItem(tempPosition,fileName);
        }
      });
 
//      holder.itemView.setOnLongClickListener( new View.OnLongClickListener() {
//        @Override
//        public boolean onLongClick(View v) {
//          mOnItemClickListener.onLongClick(tempPosition,fileName);
//          return false;
//        }
//      });
    }
  }
 
  //返回子项个数
  @Override
  public int getItemCount() {
    return mFileList.size();
  }
 
 
  public interface OnItemClickListener{
    void onClickItem( int position,String fileName);
//    void onLongClickItem( int position,String fileName);
  }
 
 
  public void setOnItemClickListener(OnItemClickListener onItemClickListener ){
    this.mOnItemClickListener = onItemClickListener;
  }
}
