有时候我们开发的app须要方便用户简单登录。能够让用户使用自己的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怎样在自己的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。能够产生我们须要的App ID和App Key，例如以下图所看到的：
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYmVhcl9odWFuZ3poZW4=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="737" height="488" alt="">
然后我们须要下载Android-SDK-vxxx。下载完后解压我们能够得到两个jar包，和一个样例代码。这两个jar包是我们须要导入到自己app中的，它们的名字是：mta-sdk-1.6.2.jar、open_sdk_r5043.jar。
非常重要的參考资料是站点上提供的API文档和解压之后的Sample样例代码。
先来看一下demo效果：
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYmVhcl9odWFuZ3poZW4=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="240" height="400" alt="">
watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvYmVhcl9odWFuZ3poZW4=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="240" height="400" alt="">
接着我们開始集成，在AndroidManifest文件里增加下面内容：
<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);
总体代码例如以下：
import org.json.JSONObject; import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.widget.Toast; import com.tencent.connect.UserInfo;
import com.tencent.connect.common.Constants;
import com.tencent.tauth.IUiListener;
import com.tencent.tauth.Tencent;
import com.tencent.tauth.UiError; /**
*
* 通过调用Tencent类的login函数发起登录/校验登录态。 *
* 该API具有两个作用：
* （1）假设开发人员没有调用mTencent实例的setOpenId、setAccessToken API，
* 则该API运行正常的登录操作；
* （2）假设开发人员先调用mTencent实例的setOpenId、setAccessToken
* API。则该API运行校验登录态的操作。假设登录态有效，则返回成功给应用，
* 假设登录态失效，则会自己主动进入登录流程，将最新的登录态数据返回给应用
