MainActivity 类

public class MainActivity extends AppCompatActivity {  RecyclerVIEw rv;  List<String> mList = new ArrayList<>();  @OverrIDe  protected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.activity_main);    rv = (RecyclerVIEw) findVIEwByID(R.ID.rv);    for (int i = 0; i < 1000; i++) {      mList.add("条目" + i);    }    final MyAdapter adapter = new MyAdapter(this,mList);    adapter.setonItemClickListener(new MyAdapter.OnItemClickListener() {      @OverrIDe      public voID onClick(int position) {        Toast.makeText(getBaseContext(),"点击的是" + position + "的itemClick",Toast.LENGTH_SHORT).show();      }    });    adapter.setonItemLongClickListener(new MyAdapter.OnItemLongClickListener() {      @OverrIDe      public voID onLongClick(int position) {        //长按删除数据        mList.remove(position);        adapter.notifyDataSetChanged();      }    });    rv.setAdapter(adapter);    //布局管理器    rv.setLayoutManager(new StaggeredGrIDLayoutManager(5,StaggeredGrIDLayoutManager.VERTICAL));  }  public static class VH extends RecyclerVIEw.VIEwHolder {    TextVIEw tv;    public VH(VIEw itemVIEw) {      super(itemVIEw);      tv = (TextVIEw) itemVIEw.findVIEwByID(androID.R.ID.text1);      tv.setBackgroundResource(R.drawable.bg);    }  }}

MyAdapter.java类

public class MyAdapter extends RecyclerVIEw.Adapter<MainActivity.VH> {  Context mContext;  List<String> mList;  public MyAdapter(Context context,List<String> List) {    this.mContext = context;    this.mList = List;  }  @OverrIDe  public MainActivity.VH onCreateVIEwHolder(VIEwGroup parent,int vIEwType) {    return new MainActivity.VH(VIEw.inflate(mContext,androID.R.layout.simple_List_item_1,null));  }  @OverrIDe  public voID onBindVIEwHolder(MainActivity.VH holder,final int position) {    holder.tv.setText(mList.get(position));    //自己做item点击    holder.itemVIEw.setonClickListener(new VIEw.OnClickListener() {      @OverrIDe      public voID onClick(VIEw v) {        if (onItemClickListener != null)          onItemClickListener.onClick(position);      }    });    holder.itemVIEw.setonLongClickListener(new VIEw.OnLongClickListener() {      @OverrIDe      public boolean onLongClick(VIEw v) {        if (onItemLongClickListener != null)          onItemLongClickListener.onLongClick(position);        //返回false会在长安结束后继续点击        return true;      }    });  }  @OverrIDe  public int getItemCount() {    return mList.size();  }  /**   * 点击   */  public interface OnItemClickListener {    voID onClick(int position);  }  OnItemClickListener onItemClickListener;  public voID setonItemClickListener(OnItemClickListener onItemClickListener) {    this.onItemClickListener = onItemClickListener;  }  public interface OnItemLongClickListener {    voID onLongClick(int position);  }  OnItemLongClickListener onItemLongClickListener;  public voID setonItemLongClickListener(OnItemLongClickListener onItemLongClickListener) {    this.onItemLongClickListener = onItemLongClickListener;  }}

activity_main.xml类

<?xml version="1.0" enCoding="utf-8"?><relativeLayout xmlns:androID="@R_404_6822@://schemas.androID.com/apk/res/androID"  xmlns:tools="@R_404_6822@://schemas.androID.com/tools"  androID:ID="@+ID/activity_main"  androID:layout_wIDth="match_parent"  androID:layout_height="match_parent"  tools:context="com.example.administrator.lesson10_recyclervIEw2.MainActivity">  <androID.support.v7.Widget.RecyclerVIEw    androID:ID="@+ID/rv"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent" /></relativeLayout>
