android - Android 上的温度传感器

Question

 public class MainActivity extends Activity implements SensorEventListener {
    private TextView temperaturelabel;
    private SensorManager sensormanager;
    private Sensor temperature;

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


    temperaturelabel = (TextView) findViewById(R.id.text);

    sensormanager = (SensorManager)getSystemService(SENSOR_SERVICE);

    temperature= sensormanager.getDefaultSensor(Sensor.TYPE_AMBIENT_TEMPERATURE);

   temperaturelabel.setText(""+temperature.getPower());
 }

 protected void onResume() {
     super.onResume();
     sensormanager.registerListener(this, temperature, SensorManager.SENSOR_DELAY_FASTEST);
 }

 protected void onPause() {                 
     super.onPause();
     sensormanager.unregisterListener(this);
 }

 public void onAccuracyChanged(Sensor sensor, int accuracy) {}

 public void onSensorChanged(SensorEvent event) {   
        if (event.sensor.getType() != Sensor.TYPE_AMBIENT_TEMPERATURE) return;

        temperaturelabel.setText(""+temperature.getPower());
    }
 }

我想从设备获取温度。

我写了这段代码，我已经在 HTC One X 上试过了，但没有用。

Answer 1

从htc one x的规范来看，这台设备好像没有温度传感器。

看看它的 official specifications .
