初识Recyclerview的小Demo,下面是代码：

public classMainActivityextendsAppCompatActivity{

private RecyclerView rv;

@Override

protected voidonCreate(BundlesavedInstanceState) {

super.onCreate(savedInstanceState);

rv=newRecyclerView(this);

setContentView(rv);

/**

*这是ListView的效果

*/

rv.setLayoutManager(newLinearLayoutManager(this));

rv.setAdapter(newRecyclerView.Adapter() {

class  ViewHolder  extends   RecyclerView.ViewHolder{

private  TextView  tv;

public    ViewHolder(TextViewitemView) {

super(itemView);

tv=itemView;

}

publicTextViewgetTv() {

returntv;

}

}

@Override

public  RecyclerView.ViewHolder  onCreateViewHolder(ViewGroupparent,intviewType) {

return new  ViewHolder(newTextView(parent.getContext()));

}

@Override

public void   onBindViewHolder(RecyclerView.ViewHolderholder,intposition) {

ViewHolder  vh=(ViewHolder)holder;

vh.getTv().setText("初识RecyclerView"+position);

//                vh.getTv().setText(data[position]);

}

//获取RecyclerView子对象的数量

@Override

public int  getItemCount() {

return   100;

//                return data.length;

}

//数组

private   String[]   data=new   String[]{"TOM","JACK","ROSE"};

});

}

}
