无法获取多个传感器数据

Question

我正在玩传感器，看看我能用它做什么，所以第一步是获取传感器数据。然而，除了加速度计之外，甚至任何传感器都可以获得多个传感器。因为这是我手机上收到的唯一数据。

我试图用加速计关闭它来运行它，但不管其他感觉器都没有显示它们的数据。

public class MainActivity extends AppCompatActivity implements SensorEventListener {

   //TODO: Database variables


    //Backend variables
    private SensorManager senSensorManager;
    private Sensor senAccelerometer, senLightsensor, senTemperatureSensor;
    private boolean isRunning;
    private Handler myHandler = new Handler();
    private float ACx, ACy, ACz;

    //UI variables
    private RelativeLayout relativeLayout;
    private TextView LightResult, Debug, AcceleroResult;



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

        relativeLayout = (RelativeLayout)findViewById(R.id.relativeLayout);

        senSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
        senAccelerometer = senSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        senLightsensor = senSensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);
        senTemperatureSensor = senSensorManager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE);
        senSensorManager.registerListener(this, senAccelerometer , SensorManager.SENSOR_DELAY_NORMAL);
        senSensorManager.registerListener(this, senLightsensor , SensorManager.SENSOR_DELAY_NORMAL);


        LightResult = (TextView) findViewById(R.id.LightFound);
        AcceleroResult = (TextView) findViewById(R.id.AcceleroResult);
        Debug = (TextView) findViewById(R.id.Debug);

    }





    /**
     * using isRunning for each sensors ensures no unneeded updates are happening when app is turned off.
     */
    @Override
    public void onSensorChanged(SensorEvent event) {
        Sensor mySensor = event.sensor;

        myHandler.post(  new Runnable() {
         public void run() {
             LightResult.setText(String.valueOf(lx));
             AcceleroResult.setText(String.valueOf(ACx));

         }
       }
       );


       if (mySensor.getType() == Sensor.TYPE_LIGHT && isRunning) {

            float lx = event.values[0];
            LightResult.setText(String.valueOf(lx));


        }
      else  if (mySensor.getType() == Sensor.TYPE_ACCELEROMETER && isRunning) {
            ACx = event.values[0];
            ACy = event.values[1];
            ACz = event.values[2];

           AcceleroResult.setText(String.valueOf(ACx));
       }
       else if(mySensor.getType() == Sensor.TYPE_AMBIENT_TEMPERATURE && isRunning){

        }

    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {

    }

    //Sensors dont run when app is not in foreground
    protected void onPause() {
        super.onPause();
        senSensorManager.unregisterListener(this);
        isRunning = false;
    }
    //Turns sensors on when the app is in the foreground
    protected void onResume() {
        super.onResume();
        senSensorManager.registerListener(this, senAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
        senSensorManager.registerListener(this, senTemperatureSensor, SensorManager.SENSOR_DELAY_NORMAL);
        senSensorManager.registerListener(this, senLightsensor, SensorManager.SENSOR_DELAY_NORMAL);
        isRunning = true;
    }
}
