Android功能：实现手动解析JSON数据

上一章：Android功能： 实现GSON解析JSON数据

效果图：

public class MainActivity extends AppCompatActivity {
    private static final String TAG = "MainActivity";   //Log-Name
    private CardBean cardBean = new CardBean();         //新增代码

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

    //请求服务器数据
    private void queryOkHttp() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    JSONObject jsonObject = new JSONObject();
                    jsonObject.put("UserName", "user1");      
                    jsonObject.put("CarId",1);                 
                    final JSONObject result = OkHttp.send("GetCarAccountBalance.do", jsonObject);
                    Log.i(TAG, "run: " + result);   
                    parsingJson(result);      //手动解析JSON数据
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }

	//手动解析JSON数据，根据服务器返回的对应键名来取值并且赋值给bean
    private void parsingJson(JSONObject result) throws JSONException {
        try {
                bean.setPm2_5(result.getInt("pm2.5"));
                bean.setCo2(result.getInt("co2"));
                bean.setHumidity(result.getInt("humidity"));
                bean.setLightIntensity(result.getInt("LightIntensity"));
                bean.setTemperature(result.getInt("temperature"));
        }catch (JSONException e){
            e.printStackTrace();
        }
    }
}
