实现第三方登录，并获取头像信息

libs里面的jar文件

在主activity里面

public class MainActivity extends AppCompatActivity implements View.OnClickListener {

简单布局

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.bwie.qqphoto.MainActivity">


    <Button
        android:id="@+id/log"
        android:text="点击登录扣扣"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <ImageView
        android:id="@+id/head"
        android:layout_below="@+id/log"
        android:layout_width="match_parent"
        android:layout_height="200dp" />
    <TextView
        android:layout_below="@+id/head"
        android:id="@+id/name"
        android:text="name"
        android:padding="10dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</RelativeLayout>
在清单文件中配置权限

<!-- QQ登录授权所需权限 -->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

< application>

<!-- 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"/>

</ application>
