从北方寻找角度

Question

我正在尝试编写一个可以从北方找到角度的应用程序（方位角）手机需要保持（纵向模式和横向模式）我粘贴在下面的代码似乎可以工作，但有时会出错值。有没有更好的方法呢？这也适用于所有手机吗？我正在使用Sensor.TYPE_ROTATION_VECTOR获取以下代码。

    int  axisX = 0;
    int axisY=0;


    switch (getWindowManager().getDefaultDisplay().getRotation())
    {
        case Surface.ROTATION_0:
            axisX = SensorManager.AXIS_Z  ;//SensorManager.AXIS_X;
            axisY = SensorManager.AXIS_MINUS_X;
          //  rotation.setText("Rotaion: 0");
            break;

        case Surface.ROTATION_90:
            axisX = SensorManager.AXIS_Z  ;//SensorManager.AXIS_X;
            axisY = SensorManager.AXIS_MINUS_X;
           // rotation.setText("Rotaion: 90");
            break;

        case Surface.ROTATION_180:
            axisX = SensorManager.AXIS_MINUS_X;
            axisY = SensorManager.AXIS_MINUS_Y;
           // rotation.setText("Rotaion: 180");
            break;

        case Surface.ROTATION_270:
            axisX =  SensorManager.AXIS_Z;//SensorManager.AXIS_MINUS_Y;
            axisY = SensorManager.AXIS_MINUS_X;;//SensorManager.AXIS_X;
           // rotation.setText("Rotaion: 270");
            break;

        default:
            break;
    }

    //
    float[] rotationMatrix = new float[9];

    SensorManager.getRotationMatrixFromVector(rotationMatrix,event.values);


    float[] adjustedRotationMatrix = new float[9];

    SensorManager.remapCoordinateSystem(rotationMatrix, axisX,axisY, adjustedRotationMatrix);

    float[] orientation = new float[3];
    SensorManager.getOrientation(adjustedRotationMatrix, orientation);
    float azimuth =(float) Math.toDegrees( orientation[0])       ;// * FROM_RADS_TO_DEGS;
