package com.example.administrator.recyclerviewtest; import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.TextView; import java.util.List; public class MyRecyclerViewAdapter extends RecyclerView.Adapter{ private List mList; static class ViewHolder extends RecyclerView.ViewHolder{ View myView; ImageView imageView; TextView title; public ViewHolder(View itemView) { super(itemView); myView = itemView; imageView = (ImageView) itemView.findViewById(R.id.iv_image); title = (TextView) itemView.findViewById(R.id.tv_title); } } public MyRecyclerViewAdapter(List list){ this.mList = list; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.message_main_notice_list,null); final ViewHolder holder = new ViewHolder(view); return holder; } //将数据绑定到控件上 @Override public void onBindViewHolder(ViewHolder holder, int position) { ItemBean bean = mList.get(position); holder.imageView.setBackgroundResource(bean.itemImage); holder.title.setText(bean.itemTitle); } @Override public int getItemCount() { return mList.size(); } //下面两个方法提供给页面刷新和加载时调用 public void add(List addMessageList) { //增加数据 int position = mList.size(); mList.addAll(position, addMessageList); notifyItemInserted(position); } public void refresh(List newList) { //刷新数据 mList.removeAll(mList); mList.addAll(newList); notifyDataSetChanged(); } }
主方法:
package com.example.administrator.recyclerviewtest; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.support.v7.widget.GridLayoutManager; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import java.util.ArrayList; import java.util.Date; import java.util.List; public class MainActivity extends AppCompatActivity { private RecyclerView recyclerView; private Listlist; private MyRecyclerViewAdapter myAdapte1r; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); list = new ArrayList (); for ( int i=0; i< 19;i++){ list.add(new ItemBean( R.mipmap.logo, "Hello", new Date().toString()+"" )); } myAdapte1r = new MyRecyclerViewAdapter(list); recyclerView = (RecyclerView) findViewById(R.id.message_notice_list_item); //纵向线性布局 //LinearLayoutManager layoutManager = new LinearLayoutManager(this); //纵向线性布局 GridLayoutManager layoutManager = new GridLayoutManager(this,2); recyclerView.setLayoutManager(layoutManager); recyclerView.setAdapter(myAdapte1r); } }
