生成Json文件

 使用jsoup-1.10.1.jar创建json格式文件

生成如下格式：

{
    "Phone":["123214123124","3123124132"],
    "married":false,
    "address":{"province":"bejing","country":"china"},
    "age":100,
    "name":"yang"
}

{}有大括号的是对象，使用JSONObject

[] 中括号的是数组，使用JSONArray

具体代码：

public class MainActivity extends AppCompatActivity{

    private TextView mTextView;
    private Button mButton;

    @Override
    protected void onCreate ( Bundle savedInstanceState ) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mTextView = (TextView)findViewById(R.id.tv_content);
    }

    //构造一个Json对象
    public void query(View view){
        try{
            //首先最外层是{}，创建一个对象
            JSONObject person = new JSONObject();
            //第一个键phone的值是数组，所以需要创建数组对象
            JSONArray phone = new JSONArray();
            phone.put("123214123124").put("3123124132");
            person.put("Phone",phone);
            
            person.put("name","yang");
            person.put("age",100);
            
            //键address的值是对象，所以要创建一个对象
            JSONObject address = new JSONObject();
            address.put("country","china");
            address.put("province","bejing");
            person.put("address",address);
            person.put("married",false);
            System.out.println(person.toString());
            mTextView.setText(person.toString());
        }
        catch(Exception e){
            e.printStackTrace();
            }
    
        }
}
