什么是安卓方向传感器的替代？

嗨，我正在构buildAndroid的3D游戏。

我目前正在尝试添加一个传感器到我的游戏，允许玩家倾斜android作为其控制。

理想情况下，我想使用ORIENTATION传感器，但我注意到它已被弃用。 有谁知道如何检测在android的倾斜，不使用这个传感器？

没有实际的“定位”传感器 – 这实际上是一个复合传感器，由加速度计和放大器组合而成。

从http://developer.android.com/reference/android/hardware/SensorEvent.html

“这种传感器types存在原因，请使用getRotationMatrix（）和remapCoordinateSystem（）和getOrientation（）来计算这些值。

public class OrientationTestActivity extends Activity implements SensorEventListener { private SensorManager mSensorManager; private Sensor mAccelerometer; private Sensor mMagnetometer; private float[] mLastAccelerometer = new float[3]; private float[] mLastMagnetometer = new float[3]; private boolean mLastAccelerometerSet = false; private boolean mLastMagnetometerSet = false; private float[] mR = new float[9]; private float[] mOrientation = new float[3]; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE); mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER); mMagnetometer = mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD); } protected void onResume() { super.onResume(); mLastAccelerometerSet = false; mLastMagnetometerSet = false; mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL); mSensorManager.registerListener(this, mMagnetometer, SensorManager.SENSOR_DELAY_NORMAL); } protected void onPause() { super.onPause(); mSensorManager.unregisterListener(this); } public void onAccuracyChanged(Sensor sensor, int accuracy) { } @Override public void onSensorChanged(SensorEvent event) { if (event.sensor == mAccelerometer) { System.arraycopy(event.values, 0, mLastAccelerometer, 0, event.values.length); mLastAccelerometerSet = true; } else if (event.sensor == mMagnetometer) { System.arraycopy(event.values, 0, mLastMagnetometer, 0, event.values.length); mLastMagnetometerSet = true; } if (mLastAccelerometerSet && mLastMagnetometerSet) { SensorManager.getRotationMatrix(mR, null, mLastAccelerometer, mLastMagnetometer); SensorManager.getOrientation(mR, mOrientation); Log.i("OrientationTestActivity", String.format("Orientation: %f, %f, %f", mOrientation[0], mOrientation[1], mOrientation[2])); } } }
