显示带有气压和高度的温度值

Question

我在文本视图中显示我的温度传感器值，并在另外两个文本视图中显示气压传感器的气压和高度问题是第一个文本视图显示气压而不是显示温度，其他文本视图显示正确的气压和高度值，我将文本视图 id 命名为正确但是当我运行应用程序时它不显示温度在同一个 activity 的第一个文本视图中，如果我将它们分成两个活动，效果很好，但我想在同一个 activity 中显示它们，这是我的代码

  public class TemperatureActivity extends Activity
    implements SensorEventListener {
private SensorManager mSensorManager;
private Sensor mSensor;
private boolean isSensorPresent;
private TextView mTemperatureValue;
private TextView mPressureValue;
private TextView mAltitudeValue;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mSensorManager =
            (SensorManager)this.getSystemService
                    (Context.SENSOR_SERVICE);
    mTemperatureValue =
            (TextView)findViewById(R.id.temperaturetext);
    if(mSensorManager.getDefaultSensor
            (Sensor.TYPE_AMBIENT_TEMPERATURE) != null) {
        mSensor = mSensorManager.getDefaultSensor
                (Sensor.TYPE_AMBIENT_TEMPERATURE);
        isSensorPresent = true;
    } else {
        mTemperatureValue.setText("Ambient Temperature Sensor is not available!");
        isSensorPresent = false;
    }


    mPressureValue =
            (TextView)findViewById(R.id.pressuretext);
    mAltitudeValue =
            (TextView)findViewById(R.id.altitudetext);
    mSensorManager = (SensorManager)
            this.getSystemService(Context.SENSOR_SERVICE);
    if(mSensorManager.getDefaultSensor
            (Sensor.TYPE_PRESSURE) != null) {
        mSensor = mSensorManager.getDefaultSensor
                (Sensor.TYPE_PRESSURE);
        isSensorPresent = true;
    } else {
        isSensorPresent = false;
        mPressureValue.setText("Pressure Sensor is not available!");
        mAltitudeValue.setText("Cannot calculate altitude, as pressure 
     Sensor is not available!");
    }





}
@Override
protected void onResume() {
    super.onResume();
    if(isSensorPresent) {
        mSensorManager.registerListener(this, mSensor,
                SensorManager.SENSOR_DELAY_NORMAL);
    }
}
@Override
protected void onPause() {
    super.onPause();
    if(isSensorPresent) {
        mSensorManager.unregisterListener(this);
    }
}
@Override
public void onSensorChanged(SensorEvent event) {
    mTemperatureValue.setText("Temperature in degree Celsius is " + 
   event.values[0]);

   float pressure = event.values[0];
    mPressureValue.setText("Pressure in mbar is " +
            pressure);
    float altitude = SensorManager.getAltitude
            (SensorManager.PRESSURE_STANDARD_ATMOSPHERE,
                    pressure);
    mAltitudeValue.setText("Current altitude is " +
            altitude);

}

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

  }



}

Answer 1

@Override
public void onSensorChanged(SensorEvent event) {
    mTemperatureValue.setText("Temperature in degree Celsius is " + 
   event.values[0]);

   float pressure = event.values[0];
    mPressureValue.setText("Pressure in mbar is " +
            pressure);
    float altitude = SensorManager.getAltitude
            (SensorManager.PRESSURE_STANDARD_ATMOSPHERE,
                    pressure);
    mAltitudeValue.setText("Current altitude is " +
            altitude);

}

彻底崩溃。每个传感器事件，您都将相同的值写入多个字段。每个传感器获得一个事件。您应该仅在收到温度事件时更新温度，仅在收到压力事件时更新压力，等等。
