一個簡單的網(wǎng)格布局

activity_main.xml

<?xml version='1.0' encoding='utf-8'?><android.support.constraint.ConstraintLayout xmlns:android='http://schemas.android.com/apk/res/android' xmlns:app='http://schemas.android.com/apk/res-auto' xmlns:tools='http://schemas.android.com/tools' android:layout_width='match_parent' android:layout_height='match_parent' tools:context='.MainActivity'> <android.support.v7.widget.RecyclerView android: android:layout_width='match_parent' android:layout_height='match_parent' /></android.support.constraint.ConstraintLayout>

message_main_notice_list.xml

<?xml version='1.0' encoding='utf-8'?><LinearLayout xmlns:android='http://schemas.android.com/apk/res/android' android:layout_width='wrap_content' android:layout_height='150dp' android:gravity='center' android:background='@color/colorAccent' android:orientation='vertical' android:layout_marginTop='5dp' > <ImageView android: android:layout_width='100dp' android:layout_height='100dp' android:background='@mipmap/logo' android:gravity='center'></ImageView> <LinearLayout android:layout_width='60dp' android:layout_height='match_parent' android:orientation='vertical' android:paddingLeft='5dp'> <TextView android: android:layout_width='match_parent' android:layout_height='30dp' android:gravity='center' android:text='BIBIA'></TextView> </LinearLayout></LinearLayout>

適配器MyRecyclerViewAdapter.java：

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<MyRecyclerViewAdapter.ViewHolder>{ private List<ItemBean> 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<ItemBean> 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; } //將數(shù)據(jù)綁定到控件上 @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(); } //下面兩個方法提供給頁面刷新和加載時調(diào)用 public void add(List<ItemBean> addMessageList) { //增加數(shù)據(jù) int position = mList.size(); mList.addAll(position, addMessageList); notifyItemInserted(position); } public void refresh(List<ItemBean> newList) { //刷新數(shù)據(jù) 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 List<ItemBean> list; private MyRecyclerViewAdapter myAdapte1r; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); list = new ArrayList<ItemBean>(); 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); //縱向線性布局 //LinearLayoutManager layoutManager = new LinearLayoutManager(this); //縱向線性布局 GridLayoutManager layoutManager = new GridLayoutManager(this,2); recyclerView.setLayoutManager(layoutManager); recyclerView.setAdapter(myAdapte1r); }}
