Java基础知识强化之网络编程笔记22：Android网络通信之 Android常用OAuth登录（获取个人信息）

1. 获取百度个人信息（使用Gson解析）：

2. 代码案例：

（1）工程一览图，如下：

（2）activity_main.xml：

 1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 2     xmlns:tools="http://schemas.android.com/tools"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:orientation="vertical"
 6     tools:context="com.himi.oauthdemo.MainActivity" >
 7     <Button
 8         android:id="@+id/btn_oauth"
 9         android:layout_width="wrap_content"
10         android:layout_height="wrap_content"
11         android:text="Baidu OAuth"
12         android:onClick="onClickOAuth"/>
13 
14     <TextView
15         android:id="@+id/tv_access_token"
16         android:layout_width="wrap_content"
17         android:layout_height="wrap_content"
18         android:text="@string/hello_world" />
19     
20     <Button
21         android:id="@+id/btn_get_user_info"
22         android:layout_width="wrap_content"
23         android:layout_height="wrap_content"
24         android:text="Baidu Get User Info"
25         android:onClick="onClickGetUserInfo"/>
26 
27     <TextView
28         android:id="@+id/tv_result"
29         android:layout_width="wrap_content"
30         android:layout_height="wrap_content"
31         android:text="@string/hello_world" />
32 
33 </LinearLayout>

布局效果，如下：
