Question

我正在制作一个Compass应用程序，而且我已经弃用了Sensor.TYPE_ORIENTATITON，我不知道如何修复它。是否有可能得到一些帮助。这是我的代码和我所做的。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_compass);

    // 
    // TextView that will tell the user what degree is he heading
    tvHeading = (TextView) findViewById(R.id.tvHeading);

    // initialize your android device sensor capabilities
    mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
}

@Override
protected void onResume() {
    super.onResume();

    // for the system's orientation sensor registered listeners
    mSensorManager.registerListener(this, **mSensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION),
            SensorManager.SENSOR_DELAY_GAME);**
}

@Override
protected void onPause() {
    super.onPause();

    // to stop the listener and save battery
    mSensorManager.unregisterListener(this);
}

@Override
public void onSensorChanged(SensorEvent event) {

    // get the angle around the z-axis rotated
    float degree = Math.round(event.values[0]);

    tvHeading.setText("Heading: " + Float.toString(degree) + " degrees");

    // create a rotation animation (reverse turn degree degrees)
    RotateAnimation ra = new RotateAnimation(
            currentDegree,
            -degree,
            Animation.RELATIVE_TO_SELF, 0.5f,
            Animation.RELATIVE_TO_SELF,
            0.5f);

    // how long the animation will take place
    ra.setDuration(210);

    // set the animation after the end of the reservation status
    ra.setFillAfter(true);

    // Start the animation
    image.startAnimation(ra);
    currentDegree = -degree;

}

这个想法是在执行代码后，它必须根据指南针检测到的程度旋转图像。
