本文实例为大家分享了android recyclerview使用的具体代码，供大家参考，具体内容如下

package com.itheima74.recyclerview; 
 
import android.os.bundle; 
import android.support.v7.app.appcompatactivity; 
import android.support.v7.widget.gridlayoutmanager; 
import android.support.v7.widget.recyclerview; 
import android.view.view; 
import android.view.viewgroup; 
import android.widget.imageview; 
import android.widget.textview; 
 
import java.util.arraylist; 
 
/** 
 * recyclerview 
 * 1.增强版的listview 
 * 2.官方推荐 
 * 3.使用步骤: 
 * a.build.gradle文件中添加依赖compile 'com.android.support:recyclerview-v7:25.2.0' 
 * b.xml布局中引入,注意完整包名+类名 
 * c.具体见代码
