Android实现QQ登录功能

qq登录是一个非常简单的一个第三方应用，现在，我们就来实现一个qq登录
首先下载两个jar包   这里上传不了jar包，所以可以到我的github中下载工程中libs中的两个jar包

网址：

打代码前，先把这些东西写上：

private static final string tag = "mainactivity"; 
private static final string app_id = "1105602574";//官方获取的appid 
private tencent mtencent; 
private baseuilistener miuilistener; 
private userinfo muserinfo; 

在androidmanifest.xml中加入权限  

<uses-permission android:name="android.permission.internet" />
<uses-permission android:name="android.permission.access_network_state" />

 <!-- 注册sdkactivity --> 
  <activity 
   android:name="com.tencent.tauth.authactivity" 
   android:launchmode="singletask" 
   android:nohistory="true" > 
   <intent-filter> 
    <action android:name="android.intent.action.view" /> 
    <category android:name="android.intent.category.default" /> 
    <category android:name="android.intent.category.browsable" /> 
    <data android:scheme="tencent1105602574" /> <!-- 开放平台获取的appid --> 
   </intent-filter> 
  </activity> 
  <activity android:name="com.tencent.connect.common.assistactivity" 
   android:theme="@android:style/theme.translucent.notitlebar" 
   android:screenorientation="portrait"/> 

 xml布局中的

<?xml version="1.0" encoding="utf-8"?> 
<linearlayout 
 xmlns:android="http://schemas.android.com/apk/res/android" 
 xmlns:app="http://schemas.android.com/apk/res-auto" 
 android:orientation="vertical" 
 xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" 
 android:layout_height="match_parent" tools:context="com.bwei.czx.czx0914qq.mainactivity"> 
 
 <button 
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:text="登录" 
  android:id="@+id/login"/> 
 <textview 
  android:layout_width="match_parent" 
  android:layout_height="wrap_content" 
  android:id="@+id/name"/> 
 <imageview 
  android:layout_width="100dp" 
  android:layout_height="80dp" 
  android:id="@+id/img"/> 
 
</linearlayout> 

下面开始mainactivity中的代码

 @override

  setcontentview(r.layout.activity_main); 
  //传入参数appid和全局context上下文 
  mtencent = tencent.createinstance(app_id, mainactivity.this.getapplicationcontext()); 
 
  initview(); 
  login.setonclicklistener(new view.onclicklistener() { 
   @override

    miuilistener = new baseuilistener(); 
    //all表示获取所有权限

    muserinfo.getuserinfo(miuilistener); 
   } 
  }); 
 }

  login = (button) findviewbyid(r.id.login); 
  name = (textview) findviewbyid(r.id.name); 
  img = (imageview) findviewbyid(r.id.img); 
 } 
 /**

       imageloaderconfiguration configuration = new imageloaderconfiguration.builder(mainactivity.this).build();

      } catch (exception e) {

      } 
     } 
 
     @override

     } 
 
     @override
