Android之QQ授权登录获取用户信息

有时候我们开发的app需要方便用户简单登录，可以让用户使用自己的qq、微信、微博登录到我们自己开发的app。

今天就在这里总结一下如何在自己的app中集成QQ授权登录获取用户信息的功能。

首先我们打开腾讯开发平台这个网页，点击---->移动应用---->创建应用，成功创建应用后，可以产生我们需要的App ID和App Key，如下图所示：

然后我们需要下载Android-SDK-vxxx，下载完后解压我们可以得到两个jar包，和一个例子代码，这两个jar包是我们需要导入到自己app中的，它们的名字是：mta-sdk-1.6.2.jar、open_sdk_r5043.jar。

很重要的参考资料是网站上提供的API文档和解压之后的Sample例子代码。

先来看一下demo效果：

      

接着我们开始集成，在AndroidManifest文件中加入以下内容：

    <uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.bear.qqlogin.MainActivity"            android:label="@string/app_name" >            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>        <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="1104732758" />            </intent-filter>        </activity>        <activity            android:name="com.tencent.connect.common.AssistActivity"            android:configChanges="orientation|keyboardHidden|screenSize"            android:theme="@android:style/Theme.Translucent.NoTitleBar" />    </application>

在主程序里面实现登录和获取用户信息，主要起作用的语句：

mTencent.login(MainActivity.this, scope, loginListener); //登录

userInfo = new UserInfo(MainActivity.this, mTencent.getQQToken()); //获取用户信息
userInfo.getUserInfo(userInfoListener);

整体代码如下：
