這篇文章主要為大家詳細介紹了Android實現(xiàn)QQ登錄功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

QQ登錄是一個非常簡單的一個第三方應用，現(xiàn)在，我們就來實現(xiàn)一個QQ登錄
首先下載兩個jar包這里上傳不了jar包，所以可以到我的github中下載工程中l(wèi)ibs中的兩個jar包

網(wǎng)址：https://github.com/chengzexiang/qqlogin

打代碼前，先把這些東西寫上：

private static final String TAG = "MainActivity"; 
private static final String APP_ID = "1105602574";//官方獲取的APPID 
private Tencent mTencent; 
private BaseUiListener mIUiListener; 
private UserInfo mUserInfo;

在AndroidManifest.xml中加入權限

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

 <!-- 注冊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" /> <!-- 開放平臺獲取的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="登錄" 
  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>

下面開始MainActivity中的代碼
