下面给出获取手机内传感器的实现代码：

    Log.d("BruceZhang", "以下是你的手机里的传感器：");List<Sensor> sensors=sensorManager.getSensorList(Sensor.TYPE_ALL);Log.d("BruceZhang", "--->");for(Sensor sensor: sensors){Log.d("BruceZhang", sensor.getName());}//通过使用getDefaultSensor方法获得一个特定的传感器
//              Sensor sensor=sensorManager.getDefaultSensor(Sensor.TYPE_GRAVITY);

在知道怎么获取传感器之后，我们需要使用程序获取传感器的值，下面给出实例代码：

        SensorManager sensorManager=(SensorManager)getSystemService(Context.SENSOR_SERVICE);Sensor sensor=sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);sensorManager.registerListener(new SensorEventListener() {/** SensorEvent event* 一旦传感器感知外界条件发生变化，就会把相应的数据传递给这个对象* 一般会把这个方法放在onCreate里，不用手动的去获取*/@Overridepublic void onSensorChanged(SensorEvent event) {// TODO Auto-generated method stubfloat auc=event.accuracy;//这里的第一个元素代表的是光线的强度float lux=event.values[0];Log.d("BruceZhang", auc+"");Log.d("BruceZhang", lux+"");}@Overridepublic void onAccuracyChanged(Sensor sensor, int accuracy) {// TODO Auto-generated method stub}}, sensor, SensorManager.SENSOR_DELAY_NORMAL);//SensorManager.SENSOR_DELAY_NORMAL//这个参数就是设置传感器的采样率}

传感器有一系列的属性：

1、传感器的采样率
  a) SENSOR_DELAY_NOMAL    (200000微秒)
  b) SENSOR_DELAY_UI       (60000微秒)
  c) SENSOR_DELAY_GAME     (20000微秒)
  d) SENSOR_DELAY_FASTEST  (0微秒)
  
2、传感器的属性
  a) 传感器的名称
  b) 传感器制造商
  c) 传感器功率
  d) 传感器的resulotion

获取这些属性的方法也很简单，代码如下：

SensorManager sensorManager=(SensorManager)getSystemService(Context.SENSOR_SERVICE);Sensor sensor=sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);sensorManager.registerListener(new SensorEventListener() {@Overridepublic void onSensorChanged(SensorEvent event) {// TODO Auto-generated method stub//传感器的名字String sensorName=event.sensor.getName();//传感器制造商的名字String sensorVendor=event.sensor.getVendor();//传感器的分辨率，传感器所能识别的最小的精度是多少float sensorRevolution=event.sensor.getResolution();//传感器的功率float sensorPower=event.sensor.getPower();//传感器取得数据的时间是多少double timeStamp=event.timestamp;//打印数据Log.d("BruceZhang", sensorName+"");Log.d("BruceZhang", sensorVendor+"");Log.d("BruceZhang", sensorRevolution+"");Log.d("BruceZhang", sensorPower+"");Log.d("BruceZhang", timeStamp+"");}@Overridepublic void onAccuracyChanged(Sensor sensor, int accuracy) {// TODO Auto-generated method stub}}, sensor, SensorManager.SENSOR_DELAY_NORMAL);}

下面实现的这个实例实现了上述内容的综合：

实例的完整代码如下：

/** 传感器会通过传感器事件把值传给用户* 所以，我们的应用程序是被动的，等待传感器把数据传递给SensorEvent对象*/
public class MainActivity extends Activity {private Button button;private Button button2;private Button button3;private SensorManager sensorManager;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//得到SensorManager对象sensorManager=(SensorManager)getSystemService(Context.SENSOR_SERVICE);button=(Button)findViewById(R.id.sensorButton);button2=(Button)findViewById(R.id.lightButton);button3=(Button)findViewById(R.id.lightButton2);button3.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubSensorManager sensorManager=(SensorManager)getSystemService(Context.SENSOR_SERVICE);Sensor sensor=sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);sensorManager.registerListener(new SensorEventListener() {@Overridepublic void onSensorChanged(SensorEvent event) {// TODO Auto-generated method stub//传感器的名字String sensorName=event.sensor.getName();//传感器制造商的名字String sensorVendor=event.sensor.getVendor();//传感器的分辨率，传感器所能识别的最小的精度是多少float sensorRevolution=event.sensor.getResolution();//传感器的功率float sensorPower=event.sensor.getPower();//传感器取得数据的时间是多少double timeStamp=event.timestamp;//打印数据Log.d("BruceZhang", sensorName+"");Log.d("BruceZhang", sensorVendor+"");Log.d("BruceZhang", sensorRevolution+"");Log.d("BruceZhang", sensorPower+"");Log.d("BruceZhang", timeStamp+"");}@Overridepublic void onAccuracyChanged(Sensor sensor, int accuracy) {// TODO Auto-generated method stub}}, sensor, SensorManager.SENSOR_DELAY_NORMAL);}});button2.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubSensorManager sensorManager=(SensorManager)getSystemService(Context.SENSOR_SERVICE);Sensor sensor=sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);sensorManager.registerListener(new SensorEventListener() {/** SensorEvent event* 一旦传感器感知外界条件发生变化，就会把相应的数据传递给这个对象* 一般会把这个方法放在onCreate里，不用手动的去获取*/@Overridepublic void onSensorChanged(SensorEvent event) {// TODO Auto-generated method stubfloat auc=event.accuracy;//这里的第一个元素代表的是光线的强度float lux=event.values[0];Log.d("BruceZhang", auc+"");Log.d("BruceZhang", lux+"");}@Overridepublic void onAccuracyChanged(Sensor sensor, int accuracy) {// TODO Auto-generated method stub}}, sensor, SensorManager.SENSOR_DELAY_NORMAL);//SensorManager.SENSOR_DELAY_NORMAL//这个参数就是设置传感器的采样率}});button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubLog.d("BruceZhang", "以下是你的手机里的传感器：");List<Sensor> sensors=sensorManager.getSensorList(Sensor.TYPE_ALL);Log.d("BruceZhang", "--->");for(Sensor sensor: sensors){Log.d("BruceZhang", sensor.getName());}//通过使用getDefaultSensor方法获得一个特定的传感器
//              Sensor sensor=sensorManager.getDefaultSensor(Sensor.TYPE_GRAVITY);}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.activity_main, menu);return true;}}
