【Android】第三方QQ账号登录的实现

在APP开发过程中，时常会用到第三方账号登录体系。

下面，简要说明QQ的第三方登录体系在Android平台上的运用。

申请APPID

进入QQ互联的官网，http://connect.qq.com/

在管理中心中创建移动应用。

创建完成后，可以得到APPID。

并在下方的协作者测试号中，填写控应用测试用的QQ号码。

导入Jar包

将下载得到的Jar包导入工程，并在AndroidManifest.xml文件中进行注册。

        <activityandroid:name="com.tencent.tauth.AuthActivity"android:noHistory="true"android:launchMode="singleTask" ><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="tencent100546930" /></intent-filter></activity>

其中，<data android:scheme="tencent100546930" />中的数字需要替换成自己申请得到的APPID。

创建登录接口

所有的SDK接口调用，都会传入一个回调，用以接收SDK返回的调用结果。回调的主要接口有两种：

（1） IUiListener：调用SDK已经封装好的接口时，例如：登录、快速支付登录、应用分享、应用邀请等接口。

（2） IRequestListener：使用requestAsync、request等通用方法调用sdk未封装的接口时，例如上传图片、查看相册等。

在这里创建IUiListener接口实现相应的登录授权操作：

    private void onClickLogin() {if (!mTencent.isSessionValid()) {IUiListener listener = new IUiListener() {/** 授权失败的回调*/@Overridepublic void onError(UiError arg0) {// TODO Auto-generated method stubToast.makeText(LoginActivity.this, "授权失败", 1000).show();Message msg = new Message();msg.arg1 = 2;handler.sendMessage(msg);    }/** 授权成功的回调*/@Overridepublic void onComplete(JSONObject arg0) {// TODO Auto-generated method stubToast.makeText(LoginActivity.this, "授权成功", 1000).show();Message msg = new Message();msg.what = 2;msg.arg1 = 1;msg.obj = arg0;handler.sendMessage(msg);}/** 取消授权的回调*/@Overridepublic void onCancel() {// TODO Auto-generated method stubToast.makeText(LoginActivity.this, "取消授权", 1000).show();Message msg = new Message();msg.arg1 = 3;handler.sendMessage(msg); }};mTencent.login(this, SCOPE, listener);} else {mTencent.logout(this);}}

其中，mTencent为QQSDK主要实现类Tencent类的实例。

       // Tencent类是SDK的主要实现类，开发者可通过Tencent类访问腾讯开放的OpenAPI。// 其中APP_ID是分配给第三方应用的appid，类型为String。mTencent = Tencent.createInstance(APP_ID, this.getApplicationContext());

将handler进行实例化

       handler = new Handler(this);

并将类实现Callback接口，即可对上述类进行Handler的处理操作。

   @Overridepublic boolean handleMessage(Message msg) {// TODO Auto-generated method stubswitch (msg.arg1) {case 1: { // 成功JSONObject object = (JSONObject) msg.obj;try {openid = object.getString("openid").toString();sBuilder.append("openid为："+openid+"\n");access_token = object.getString("access_token").toString();url = url + "?access_token="+access_token+"&oauth_consumer_key="+APP_ID+"&openid="+openid+"&format=json";new MyUrlThread(url.toString(), 2,sHandler).start();} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}}break;case 2: { // 失败Toast.makeText(this, "", Toast.LENGTH_SHORT).show();return false;}case 3: { // 取消Toast.makeText(this, "", Toast.LENGTH_SHORT).show();return false;}}return false;}

如果授权成功，即可得到返回的Openid。

从而，可以根据Openid调用腾讯所提供的官方接口，实现需要的操作。

接收回调

   //应用调用Andriod_SDK接口时，使能成功接收到回调@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {// TODO Auto-generated method stub
