1.傳感器事件概念
2.為應用程序注冊傳感器
3.獲取傳感器的值和精度
public boolean registerListener (SensorEventListener listener,Sensor sensor,int rate)
樣例
package org.marsdroid.sensor()2;
import android.app.Activitity;
public class MainActivity extends Activity{
//聲明一個SensorManager對象
private SensorManager sensorManager;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//獲取SensorManager對象
sensorManager=(SensorManager)getSystemService(Context.SESOR_SERVICE);
//獲取光線傳感器對象
Sensor lightSensor=sensorManager.getDefaultSensor(Sensor.TYPE_LIGHT);
//注冊傳感器
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);
}
}

編輯 收藏1.傳感器的分類
一、動作傳感器：加速度傳感器、重力傳感器和陀螺儀等
二、位置傳感器：方向傳感器和磁力傳感器
三、環境傳感器：溫度傳感器、壓力傳感器和亮度傳感器等
2.Android設備傳感器的特點
3.獲取手機當中所有傳感器的名稱
使用傳感器的方法：
1.獲取SensorManager對象
2.執行SensorManager對象的getDefaultSensor()方法獲取Sensor對象
3.獲取Sensor對象的各種屬性

編輯 收藏作為一個java的初學者，不該在這個純技術的領域，發這個博文，我且當做隨筆好點。寥寥數語，寄予我美好的未來，不斷的憧憬。我喜歡上了這首《Wish YOu were here》，尤其喜歡女生版的。O(∩_∩)O~ 聽到What I‘d do to have near near near near near near near near near

不知道為啥子原因，那個ID不存在了，轉而又有個似曾相識的 使用著不同的ID。 一個java初學者 不能去查IP 是最丟臉的事情，去查了也是很丟臉的玩意！ 姑且當做落花有意，流水無情~~
Expiration Date:
If you compel me to put it,I'll say forever!

Best wish for my best friend！
