如何在Android中创建JSON？

implementation 'com.google.code.gson:gson:2.8.8'

Gson gson = new Gson();
String json = gson.toJson(yourObject);

import com.google.gson.Gson;

public class MainActivity extends AppCompatActivity {
    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textView = findViewById(R.id.textView);

        // 创建Java对象
        Person person = new Person("John", 25);

        // 转换为JSON
        Gson gson = new Gson();
        String json = gson.toJson(person);

        // 显示JSON字符串
        textView.setText(json);
    }

    private class Person {
        private String name;
        private int age;

        public Person(String name, int age) {
            this.name = name;
            this.age = age;
        }

        // getter和setter方法
        // ...
    }
}
