1、xml添加标签RecyclerView
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v7.widget.RecyclerView>
activity
RecyclerView recyclerView = findViewById(R.id.recyclerview);
LinearLayoutManager layoutManager = new LinearLayoutManager(this);
//设置布局管理器
recyclerView.setLayoutManager(layoutManager);
//设置为垂直布局,这也是默认的
layoutManager.setOrientation(OrientationHelper.VERTICAL);
//设置Adapter
recyclerView.setAdapter(new RecyclerAdapter());
//设置分隔线
//recyclerView.addItemDecoration( new DividerGridItemDecoration(this));
//设置增加或删除条目的动画
//recyclerView.setItemAnimator( new DefaultItemAnimator());
RecyclerAdapter
class RecyclerAdapter extends RecyclerView.Adapter<ItemViewHolder> {
@Override
public ItemViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(getApplicationContext()).inflate(R.layout.rec_item, parent, false);
return new ItemViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull ItemViewHolder itemViewHolder, int i) {
itemViewHolder.title.setText(""+i);
}
@Override
public int getItemCount() {
return 20;
}
}
class ItemViewHolder extends RecyclerView.ViewHolder {
public TextView title;
private ItemViewHolder(View itemView) {
super(itemView);
title = (TextView) itemView.findViewById(R.id.title);
}
}
