1.传感器事件概念
2.为应用程序注册传感器
3.获取传感器的值和精度
public boolean registerListener (SensorEventListener listener,Sensor sensor,int rate)
样例
package org.marsdroid.sensor()2;
import android.app.Activitity;
public class MainActivity extends Activity{
//声明一个SensorManager对象
private SensorManager sensorManager;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//获取SensorManager对象
sensorManager=(SensorManager)getSystemService(Context.SESOR_SERVICE);
//获取光线传感器对象
Sensor lightSensor=sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);
//注册传感器
sensorManager.registerListener(new SensorEventListener(){
public void onSensorChanged(SensorEvent event){
float acc=event.accuracy;
float lux=event.values[0];
System.out.println("acc---->"+acc);
System.out.println("lux---->"+lux);
}
public void onAccuracyChanged(Sensor sensor,int accuracy){
}
},lightSensor,SensorManager.SENSOR_DELAY_NORMAL);
}
}

编辑 收藏1.传感器的分类
一、动作传感器：加速度传感器、重力传感器和陀螺仪等
二、位置传感器：方向传感器和磁力传感器
三、环境传感器：温度传感器、压力传感器和亮度传感器等
2.Android设备传感器的特点
3.获取手机当中所有传感器的名称
使用传感器的方法：
1.获取SensorManager对象
2.执行SensorManager对象的getDefaultSensor()方法获取Sensor对象
3.获取Sensor对象的各种属性

不知道为啥子原因，那个ID不存在了，转而又有个似曾相识的 使用着不同的ID。 一个java初学者 不能去查IP 是最丢脸的事情，去查了也是很丢脸的玩意！ 姑且当做落花有意，流水无情~~

If you compel me to put it,I'll say forever!

Best wish for my best friend！
