Android 加速度传感器 怎么转换成角度

sm = (SensorManager)getSystemService(Context.SENSOR_SERVICE);

aSensor = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);

mSensor = sm.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);

sm.registerListener(myListener, aSensor, SensorManager.SENSOR_DELAY_NORMAL);

sm.registerListener(myListener, mSensor,SensorManager.SENSOR_DELAY_NORMAL);

SensorEventListener myListener =new SensorEventListener() {

publicvoid onSensorChanged(SensorEvent sensorEvent) {

if (sensorEvent.sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD)

magneticFieldValues = sensorEvent.values;

if (sensorEvent.sensor.getType() == Sensor.TYPE_ACCELEROMETER)

accelerometerValues = sensorEvent.values;

float[] values =newfloat;

float[] R = newfloat;

SensorManager.getRotationMatrix(R, null, accelerometerValues, magneticFieldValues);

SensorManager.getOrientation(R, values);

//这里 values,values,values里边的数据就是x y z 轴 分别的角度

}

publicvoid onAccuracyChanged(Sensor sensor,int accuracy) {}

};
