Android-QQ登录

1.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
2.把open-sdk.jar拷贝到libs（或lib）目录下
（下载地址：http://wiki.open.qq.com/wiki/mobile/SDK%E4%B8%8B%E8%BD%BD）

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　　
声明

//    QQ登录相关private static final String QQAPPID = "1106263164";    private Tencent mTencent;    private IUiListener loginListener;    private IUiListener userInfoListener;    private String scope;    private UserInfo userInfo;    ImageView img_login_qq;

初始化

//          QQ登录相关        mTencent = Tencent.createInstance(QQAPPID, LoginActivity.this);        scope = "all";        initLoginListener();        initUserInfoListener();        img_login_qq= (ImageView) findViewById(R.id.img_login_qq);        img_login_qq.setOnClickListener(this);

其余见代码

/*qq登录开始 */private void qqLogin() {    if (!mTencent.isSessionValid()) {        mTencent.login(LoginActivity.this, scope, loginListener);    }}private void initLoginListener() {    loginListener = new IUiListener() {        /**         * {"ret":0,"pay_token":"D3D678728DC580FBCDE15722B72E7365",         * "pf":"desktop_m_qq-10000144-android-2002-",         * "query_authority_cost":448,         * "authority_cost":-136792089,         * "openid":"015A22DED93BD15E0E6B0DDB3E59DE2D",         * "expires_in":7776000,         * "pfkey":"6068ea1c4a716d4141bca0ddb3df1bb9",         * "msg":"",         * "access_token":"A2455F491478233529D0106D2CE6EB45",         * "login_cost":499}         */        @Override        public void onComplete(Object value) {            // TODO Auto-generated method stub            if(value==null){                Toast.makeText(getApplicationContext(),"返回结果为空",Toast.LENGTH_LONG).show();
