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="/apk/res/android" 2xmlns:tools="/tools" 3android:layout_width="match_parent" 4android:layout_height="match_parent" 5android:orientation="vertical" 6tools: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<TextView15 android:id="@+id/tv_access_token"16 android:layout_width="wrap_content"17 android:layout_height="wrap_content"18 android:text="@string/hello_world" />1920<Button21 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<TextView28 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>
