Question

对不起每个人，作为主题，我没有看到我的aAngle和bAngle的变化。

@Override
public void onCreate(Bundle savedInstanceState) {
    sensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
}

public void onResume()
{
    super.onResume();

    if (aAngleList.size() <= 50){
        List<Sensor> sensors = sensorManager.getSensorList(Sensor.TYPE_ACCELEROMETER);
        if (sensors.size() > 0 && sensors.size() <= 10) {
            sensorManager.registerListener(this, sensors.get(0), SensorManager.SENSOR_DELAY_FASTEST);
        }
    }
    else {
        sensorManager.unregisterListener(this);

        for(int i = 0; i < aAngleList.size(); i++){
            aAngleTotal += aAngleList.get(i);
            bAngleTotal += bAngleList.get(i);
            aAngleAverage = aAngleTotal / aAngleList.size();
            bAngleAverage = bAngleTotal / aAngleList.size();
        }

        calculatePosB(aAngleAverage, bAngleAverage);
        calculatePosC(aAngleAverage, bAngleAverage);
        calculatePosD(aAngleAverage, bAngleAverage);

        Log.d("ForDebug", Double.toString(bAngleAverage));
        }
    }

@Override
public void onAccuracyChanged(Sensor arg0, int arg1) {
    // TODO Auto-generated method stub

}

public void onSensorChanged(SensorEvent event) {
    // TODO Auto-generated method stub
    aAngle = -(Math.toDegrees(Math.acos(event.values[0]/Math.pow(Math.pow(event.values[0],2)+Math.pow(event.values[1],2)+Math.pow(event.values[2],2), 0.5))) - 90);
    bAngle = -(Math.toDegrees(Math.acos(event.values[1]/Math.pow(Math.pow(event.values[0],2)+Math.pow(event.values[1],2)+Math.pow(event.values[2],2), 0.5))) - 90);
    aAngleList.add(aAngle);
    bAngleList.add(bAngle);
)

我在onCreate中有我的sensormanager注册，并在onPause中取消注册，但我什么都没得到。看来我的手机没有拿到传感器？

此外，logcat没有显示Fordebug。这是否意味着我无法获得平均值，因为我的应用程序无法获取代码来获取它？

Android Sensor Manager无法正常工作
