Android中传感器的一些功能

只提供参考，自己还在学习中

方法有：

public class SensorActivity extends Activity implements SensorEventListener {
	/** Called when the activity is first created. */
	private boolean mRegisteredSensor;
	private SensorManager mSensorManager;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		mRegisteredSensor = false;
		mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
	}

	@Override
	protected void onResume() {
		// TODO Auto-generated method stub
		super.onResume();
		// 接收sensorManager的一个列表(Listener)
		// 这里我们指定类型为type_ORIENTATION（方向感应器）
		List<Sensor> sensors = mSensorManager
				.getSensorList(Sensor.TYPE_ORIENTATION);

		if (sensors.size() > 0) {
			Sensor sensor = sensors.get(0);
			mRegisteredSensor = mSensorManager.registerListener(this, sensor,
					SensorManager.SENSOR_DELAY_FASTEST);
		}
		
	}

	@Override
	protected void onPause() {

		if (mRegisteredSensor) {
			mSensorManager.unregisterListener(this);
			mRegisteredSensor = false;
		}

		super.onPause();
	}

	public void onAccuracyChanged(Sensor sensor, int accuracy) {
		// 处理精准确改变

	}

	public void onSensorChanged(SensorEvent event) {
		// 接收方向感应器的类型
		if (event.sensor.getType() == Sensor.TYPE_ORIENTATION) {
			//这里我们可以得到数据，然后根据需求来处理
			//由于模拟器上面无法测试效果，隐藏我们暂时不处理数据
			float x = event.values[SensorManager.DATA_X];
			float Y = event.values[SensorManager.DATA_Y];
			float z = event.values[SensorManager.DATA_Z];
		}

	}
}
