QQ登录的简单实现

        QQ登录是一个非常简单的一个第三方应用，现在，我们就来实现一个QQ登录首先下载两个jar包   这里上传不了jar包，所以可以到我的github中下载工程中libs中的两个jar包     网址：https://github.com/chengzexiang/qqlogin     打代码前，先把这些东西写上：      private static final String TAG = "MainActivity";private static final String APP_ID = "1105602574";//官方获取的APPIDprivate Tencent mTencent;private BaseUiListener mIUiListener;private UserInfo mUserInfo;    在AndroidManifest.xml中加入权限   

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

 <!-- 注册SDKActivity --><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="tencent1105602574" /> <!-- 开放平台获取的APPID --></intent-filter></activity><activity android:name="com.tencent.connect.common.AssistActivity"android:theme="@android:style/Theme.Translucent.NoTitleBar"android:screenOrientation="portrait"/>

 Xml布局中的

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"android:orientation="vertical"xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"android:layout_height="match_parent" tools:context="com.bwei.czx.czx0914qq.MainActivity"><Buttonandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="登录"android:id="@+id/login"/><TextViewandroid:layout_width="match_parent"android:layout_height="wrap_content"android:id="@+id/name"/><ImageViewandroid:layout_width="100dp"android:layout_height="80dp"android:id="@+id/img"/></LinearLayout>

 下面开始MainActivity中的代码
