如何将JSON对象显示到TextView？任何建议都将不胜感激。

import org.json.JSONException;
import org.json.JSONObject;

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);

        // 假设已经获取到了JSON数据
        String jsonString = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

        try {
            // 将JSON数据解析为JSONObject对象
            JSONObject jsonObject = new JSONObject(jsonString);

            // 从JSONObject对象中提取需要显示的数据
            String name = jsonObject.getString("name");
            int age = jsonObject.getInt("age");
            String city = jsonObject.getString("city");

            // 将数据显示在TextView上
            String displayText = "Name: " + name + "\nAge: " + age + "\nCity: " + city;
            textView.setText(displayText);
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}
