AndroidRecyclerView网格布局 _RecyclerView

天下之事常成于困约，而败于奢靡。这篇文章主要讲述AndroidRecyclerView网格布局相关的知识，希望能为你提供帮助。
一个简单的网格布局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:id="@+id/message_notice_list_item" 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:id="@+id/iv_image"
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:id="@+id/tv_title"
android:layout_width="match_parent"
android:layout_height="30dp"
android:gravity="center"
android:text="BIBIA"> < /TextView>

< /LinearLayout>

< /LinearLayout>

适配器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; }//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< ItemBean> addMessageList) { //增加数据 int position = mList.size(); mList.addAll(position, addMessageList); notifyItemInserted(position); }public void refresh(List< ItemBean> 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 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); //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); } }

效果：
