的Android传感器旋转角度

(横向拿着时，前后倾斜)，但我明明做我试图检测Y轴旋转角度为onSensorChanged事件永远不会触发变薄错误Android传感器旋转角度

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

...

mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);

mSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR);

mSensorManager.registerListener(this.mSensorEventListener, mSensor, SensorManager.SENSOR_DELAY_GAME);

}

...

private SensorEventListener mSensorEventListener = new SensorEventListener() {

@Override

public void onAccuracyChanged(Sensor sensor, int accuracy) {

// TODO Auto-generated method stub

}

@Override

public void onSensorChanged(SensorEvent event) {

float aX = event.values[1];

float aY = event.values[2];

double angle = aY * (Math.PI/180);

btnStop.setText(Double.toString(angle));
