android实现第三方登录之QQ登录

首先，当然是在腾讯开放平台(http://open.qq.com/)注册成为开发者，然后获取APP ID

1.下载SDK

　　http://wiki.open.qq.com/wiki/mobile/SDK%E4%B8%8B%E8%BD%BD

 2.把open-sdk.jar文件和mta_sdk_x.x.x.jar文件拷贝到libs（或lib）目录下

　　`http://wiki.open.qq.com/wiki/%E5%88%9B%E5%BB%BA%E5%B9%B6%E9%85%8D%E7%BD%AE%E5%B7%A5%E7%A8%8B`

3.配置AndroidManifest

        <uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
                <!-- 从QQ登录中copy的代码-->
        <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="tencent1105546048" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.tencent.connect.common.AssistActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:theme="@android:style/Theme.Translucent.NoTitleBar" />

4.创建实例　　　　　　         http://wiki.open.qq.com/wiki/%E5%88%9B%E5%BB%BA%E5%AE%9E%E4%BE%8B%E5%B9%B6%E5%AE%9E%E7%8E%B0%E5%9B%9E%E8%B0%83

    // 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());

5.实现回调 IUiListener

6.接收到回调
　　需要在调用接口的Activity的onActivityResult方法中增加如下代码：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Tencent.onActivityResultData(requestCode,resultCode,data,listener);
}

具体源码：

　　

    //变量 
    boolean isServerSideLogin = false;
    public static Tencent mTencent;
    
    //点击按钮之后QQ登录
    public void loginQQ(View view){
        //初始化，得到APPID
        mTencent = Tencent.createInstance(ConstantsData.QQ_APP_ID, this);
        if (!mTencent.isSessionValid()) {
            mTencent.login(this, "all", loginListener);
            isServerSideLogin = false;
            Log.d("SDKQQAgentPref", "FirstLaunch_SDK:" + SystemClock.elapsedRealtime());
        } else {
            if (isServerSideLogin) { // Server-Side 模式的登陆, 先退出，再进行SSO登陆
                mTencent.logout(this);
                mTencent.login(this, "all", loginListener);
                isServerSideLogin = false;
                Log.d("SDKQQAgentPref", "FirstLaunch_SDK:" + SystemClock.elapsedRealtime());
                return;
            }
            mTencent.logout(this);
        }
    }

    //初始化OPENID和TOKEN值（为了得了用户信息）
    public static void initOpenidAndToken(JSONObject jsonObject) {
        try {
            String token = jsonObject.getString(Constants.PARAM_ACCESS_TOKEN);
            String expires = jsonObject.getString(Constants.PARAM_EXPIRES_IN);
            String openId = jsonObject.getString(Constants.PARAM_OPEN_ID);
            if (!TextUtils.isEmpty(token) && !TextUtils.isEmpty(expires)
                    && !TextUtils.isEmpty(openId)) {
                mTencent.setAccessToken(token, expires);
                mTencent.setOpenId(openId);
            }
        } catch(Exception e) {
        }
    }

    IUiListener loginListener = new BaseUiListener() {
        @Override
        protected void doComplete(JSONObject values) {
            Log.d("SDKQQAgentPref", "AuthorSwitch_SDK:" + SystemClock.elapsedRealtime());
            initOpenidAndToken(values);
        }
    };

    //实现回调
    private class BaseUiListener implements IUiListener {

        @Override
        public void onComplete(Object response) {
            if (null == response) {
                Util.showResultDialog(LoginActivity.this, "返回为空", "登录失败");
                return;
            }
            JSONObject jsonResponse = (JSONObject) response;
            if (null != jsonResponse && jsonResponse.length() == 0) {
                Util.showResultDialog(LoginActivity.this, "返回为空", "登录失败");
                return;
            }
            Util.showResultDialog(LoginActivity.this, response.toString(), "登录成功");
            // 有奖分享处理
//            handlePrizeShare();
            doComplete((JSONObject)response);
        }

        protected void doComplete(JSONObject values) {

        }

        @Override
        public void onError(UiError e) {
            Util.toastMessage(LoginActivity.this, "onError: " + e.errorDetail);
            Util.dismissDialog();
        }

        @Override
        public void onCancel() {
            Util.toastMessage(LoginActivity.this, "onCancel: ");
            Util.dismissDialog();
            if (isServerSideLogin) {
                isServerSideLogin = false;
            }
        }
    }

    //QQ登录后的回调
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.d("TAG", "-->onActivityResult " + requestCode  + " resultCode=" + resultCode);
        if (requestCode == Constants.REQUEST_LOGIN ||
                requestCode == Constants.REQUEST_APPBAR) {
            Tencent.onActivityResultData(requestCode,resultCode,data,loginListener);
        }

        super.onActivityResult(requestCode, resultCode, data);
    }
