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

2、加入xutils包

implementation 'org.xutils:xutils:3.9.0'

2、传输数据

Gson gson=new Gson();
    Student student=gson.fromJson(result,Student.class);
    textView.setText(student.class1.classname);
