Android的Sensor.TYPE_ORIENTATION完美的作品，我不能与加速度计和磁力相同的结果 [英] Android Sensor.TYPE_ORIENTATION works perfect and I can't get the same results with accelerometer and magnetometer

问题描述

我想利用这个pcated非德$ P $的code版本，以获得取向。不过，我不能让它的工作顺利和完美的，因为如果我只是用pcated Sensor.TYPE_ORIENTATION去$ P $。我失去了一些东西？

// OLD

  @覆盖
公共无效onSensorChanged（SensorEvent为arg0）{
    m_lastYaw = arg0.values​​ [0];
    无效（）;
}
 

// NEW

  @覆盖
公共无效onSensorChanged（SensorEvent事件）{
    如果（event.accuracy == SensorManager.SENSOR_STATUS_UNRELIABLE）{
        返回;
    }

    如果（event.sensor.getType（）== Sensor.TYPE_ACCELEROMETER）{
        System.arraycopy（event.values​​，0，m_lastAccels，0，3）;
    }
    如果（event.sensor.getType（）== Sensor.TYPE_MAGNETIC_FIELD）{
        System.arraycopy（event.values​​，0，m_lastMagFields，0，3）;
    }

    如果（SensorManager.getRotationMatrix（m_rotationMatrix，空，m_lastAccels，m_lastMagFields））{
        SensorManager.getOrientation（m_rotationMatrix，m_orientation）;

        m_lastYaw =（浮点）Math.toDegrees（m_orientation [0]）;
        无效（）;
    }
}
 

解决方案

我用，我在这里提出的code 和它的工作很好，只有当手机（三星Galaxy S3）奠定持平。但它是一个开始：它不工作比 Sensor.TYPE_ORIENTATION 更好，也不更坏

I am trying to use this non-deprecated version of code to get orientation. However I can't get it to work as smooth and perfect as if I just use the deprecated Sensor.TYPE_ORIENTATION. Am I missing something?

//OLD

@Override
public void onSensorChanged(SensorEvent arg0) {
    m_lastYaw = arg0.values[0];
    invalidate();
}

//NEW

@Override
public void onSensorChanged(SensorEvent event) {
    if (event.accuracy == SensorManager.SENSOR_STATUS_UNRELIABLE){
        return;
    }

    if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
        System.arraycopy(event.values, 0, m_lastAccels, 0, 3);
    }
    if (event.sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD) {
        System.arraycopy(event.values, 0, m_lastMagFields, 0, 3);
    }

    if (SensorManager.getRotationMatrix(m_rotationMatrix, null, m_lastAccels, m_lastMagFields)) {
        SensorManager.getOrientation(m_rotationMatrix, m_orientation); 

        m_lastYaw = (float)Math.toDegrees(m_orientation[0]);
        invalidate();
    }
}

解决方案

I used the code that I posed here and it worked well only when the phone (Samsung Galaxy S3) layed flat. But it's a start: It doesn't work better than Sensor.TYPE_ORIENTATION nor worse.
