Android开发实现QQ登陆并获取信息、分享消息到QQ

很多APP都有分享文章或者图片甚至分享APP给QQ好友的功能，查阅了比较多的资料，也翻看了腾讯开放平台上的API文档，总是会出现各种各样的问题！经过几个小时的排查，也基本算是实现了一些功能！

总之：还是要多阅读官方的开发文档！

一、去官网上下载SDK

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

并且注册账号添加一个Android应用，这个就不多说了！账号注册登陆后会获取一个 APPID ，记住这个APPID，后面要用的！

二、配置项目

1、SDK下载好之后，解压，里面有一个 jar 文件夹，拷贝里面的两个jar到项目里面去

2、配置AndroidManifest.xml文件：

添加两个Activity（这两个Activity是SDK里面包含的）：

        <activityandroid: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="您的APPID" /></intent-filter></activity><activityandroid:name="com.tencent.connect.common.AssistActivity"android:configChanges="orientation|keyboardHidden|screenSize"android:theme="@android:style/Theme.Translucent.NoTitleBar" />

记得添加权限：

    <uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

三、java代码实现：

1、登录功能的实现：

需要使用的变量：

 private Button qqLogin;private String APP_ID = "1106329105";private Tencent mTencent;  //QQ主操作对象private IUiListener loginListener;  //授权登录监听器private String SCOPE = "all";  //获取信息的范围参数private String TAG = "MainActivity";

初始化QQ主

     //初始化QQ主操作对象mTencent = Tencent.createInstance(APP_ID, MainActivity.this);

实例化loginListener：

                //用户登录的回调loginListener = new IUiListener() {@Overridepublic void onError(UiError arg0) {// TODO Auto-generated method stub}@Overridepublic void onComplete(Object arg0) {if(arg0 == null){return;}else{try {JSONObject jsonObject = (JSONObject) arg0;int ret = jsonObject.getInt("ret");if(ret == 0){Log.i(TAG, "登陆成功，有数据返回:"+jsonObject.toString());Toast.makeText(MainActivity.this, "登陆成功", Toast.LENGTH_SHORT).show();String openID = jsonObject.getString("openid");String accessToken = jsonObject.getString("access_token");String expires = jsonObject.getString("expires_in");mTencent.setOpenId(openID);mTencent.setAccessToken(accessToken, expires);}} catch (JSONException e) {e.printStackTrace();}}}@Overridepublic void onCancel() {// TODO Auto-generated method stub}};

实现回调：

 @Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {if(requestCode == Constants.REQUEST_API){if(resultCode == Constants.RESULT_LOGIN){Tencent.handleResultData(data, loginListener);}}super.onActivityResult(requestCode, resultCode, data);}

给登录按钮一个监听：

qqLogin.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {Log.i(TAG, "点击了登录按钮");mTencent.login(MainActivity.this, SCOPE, loginListener);}});

到此实现了登录功能！

实现效果：

2、获取QQ用户信息：

添加两个变量：

private IUiListener userInfoListener; //获取用户信息监听器
private UserInfo userInfo; //qq用户信息

实例化userInfoListener：

     //获取用户信息的回调userInfoListener = new IUiListener() {@Overridepublic void onError(UiError arg0) {// TODO Auto-generated method stubLog.i(TAG, "获取用户信息失败");}@Overridepublic void onComplete(Object arg0) {if(arg0 == null){return;}else{try {JSONObject jsonObject = (JSONObject) arg0;int ret = jsonObject.getInt("ret");String nickName = jsonObject.getString("nickname");String gender = jsonObject.getString("gender");Log.i(TAG, "获取条用户信息成功"+jsonObject.toString());Toast.makeText(MainActivity.this, nickName, Toast.LENGTH_SHORT).show();} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}@Overridepublic void onCancel() {// TODO Auto-generated method stubLog.i(TAG, "取消获取用户信息");}};

给获取信息的按钮添加监听：

     myQQMessage.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {Log.i(TAG, "开始获取用户信息");userInfo = new UserInfo(MainActivity.this, mTencent.getQQToken());userInfo.getUserInfo(userInfoListener);             }});

到此实现了获取QQ用户信息的功能：

实现效果：

3、实现分享消息到QQ：

添加变量：

private IUiListener shareListener;  //分享消息的回调

实例化shareListener：

     //分享消息的回调shareListener = new IUiListener() {@Overridepublic void onComplete(Object o) {//分享成功后回调Toast.makeText(MainActivity.this, "分享成功！", Toast.LENGTH_SHORT).show();}@Overridepublic void onError(UiError uiError) {//分享失败后回调}@Overridepublic void onCancel() {//取消分享后回调}};

给分享消息的按钮添加监听：

     shareMessage.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {Log.i(TAG, "分享消息");Bundle params = new Bundle();params.putInt(QQShare.SHARE_TO_QQ_KEY_TYPE, QQShare.SHARE_TO_QQ_TYPE_DEFAULT);params.putString(QQShare.SHARE_TO_QQ_TITLE, "标题");params.putString(QQShare.SHARE_TO_QQ_SUMMARY,"摘要");params.putString(QQShare.SHARE_TO_QQ_TARGET_URL,"http://baidu.com");params.putString(QQShare.SHARE_TO_QQ_IMAGE_URL,"http://avatar.csdn.net/C/3/D/1_u013451048.jpg");params.putString(QQShare.SHARE_TO_QQ_APP_NAME, "CSDN");mTencent.shareToQQ(MainActivity.this, params, shareListener);}});

到此实现了QQ分享功能！

效果：

四、可以看一下整体的代码：
