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APPID private 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 --> <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="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"?> <LinearLayout xmlns: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"> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="登录" android:id="@+id/login"/> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/name"/> <ImageView android:layout_width="100dp" android:layout_height="80dp" android:id="@+id/img"/> </LinearLayout>
下面开始MainActivity中的代码

下面为显示效果
qq登录完成！
