RecyclerView 实现瀑布流 数据横向竖向排序

纵向

代码实现

• recycleActivity.xml

• RecycleActivity.class

public class RecycleActivity extends AppCompatActivity {List list=new ArrayList<>();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_recycle);//添加50条测试数据for (int i=1;i<50;i++){list.add(new Bean(i));}RecyclerView recyclerView = findViewById(R.id.recycleView1);//布局加载器  StaggeredGridLayoutManager.HORIZONTAL 为纵向   StaggeredGridLayoutManager.VERTICAL 为横向recyclerView.setLayoutManager(new StaggeredGridLayoutManager(6,StaggeredGridLayoutManager.HORIZONTAL));recyclerView.setAdapter(new RecyclerAdapter(list));}}

• RecyclerAdapter 和 ViewHolder

public class RecyclerAdapter extends RecyclerView.Adapter {List list;public RecyclerAdapter(List list1) {list=list1;}@NonNull@Overridepublic MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {View inflate = LayoutInflater.from(parent.getContext()).inflate(R.layout.item1, parent, false);return new MyViewHolder(inflate);}@Overridepublic void onBindViewHolder(@NonNull  RecyclerAdapter.MyViewHolder holder, int position) {holder.id.setText(list.get(position).getA()+" ");}@Overridepublic int getItemCount() {return list.size();}class MyViewHolder extends RecyclerView.ViewHolder{TextView id;public MyViewHolder(@NonNull View itemView) {super(itemView);id = itemView.findViewById(R.id.id1);}}
}

• item1布局

• Bean 实体类

public class Bean {private int a;public Bean(int i) {a=i;}public int getA() {return a;}public void setA(int a) {this.a = a;}
}
