**接下来，以源代码的方式分析这个例子**

**1.MainActivity--主界面**

**这个类主要是实现用户所看到的这个Activity，其中包含了一系列的按钮，用户点击按钮执行相应的动作，所以在这个类中主要是对按钮的定义和对按钮绑定相应的监听器，下面是实现的代码：**

package lovefang.stadyService;import android.app.Activity;import android.os.Bundle;import android.widget.Button;import android.view.View;import android.content.Intent;import android.util.Log;/**这是使用后台服务的学习例子*/public class MainStadyServics extends Activity {     /**参数设置*/ Button startServiceButton;// 启动服务按钮 Button shutDownServiceButton;// 关闭服务按钮 Button startBindServiceButton;// 启动绑定服务按钮 Button sendBroadcast;// 使用广播 Button notificationButton;// 使用通知功能 Button alarmButton;// 使用闹钟 Button handlerButton;// 使用handler Button asyncButton;// 使用异步加载 Button phoneStateButton;// 查看手机状态 Button callphoneButton;// 拨打电话 Button vibratorButton;// 使用震动  CountService countService;     @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        Log.v("MainStadyServics", "setContentView");        setContentView(R.layout.main);        getWidget();        regiestListener();    }     /**获得组件*/    public void getWidget(){     startServiceButton = (Button)findViewById(R.id.startServerButton);     startBindServiceButton = (Button)findViewById(R.id.startBindServerButton);     shutDownServiceButton = (Button)findViewById(R.id.sutdownServerButton);     sendBroadcast = (Button)findViewById(R.id.sendBroadcast);     notificationButton = (Button)findViewById(R.id.notification);     alarmButton = (Button)findViewById(R.id.alarm);     handlerButton = (Button)findViewById(R.id.handler);     asyncButton = (Button)findViewById(R.id.async);     phoneStateButton = (Button) findViewById(R.id.phonestate);     callphoneButton = (Button) findViewById(R.id.callphone);     vibratorButton = (Button) findViewById(R.id.vibrator);    }     /**为按钮添加监听*/    public void regiestListener(){     startServiceButton.setOnClickListener(startService);     shutDownServiceButton.setOnClickListener(shutdownService);     startBindServiceButton.setOnClickListener(startBinderService);     sendBroadcast.setOnClickListener(broadcastReceiver);     notificationButton.setOnClickListener(notification);     alarmButton.setOnClickListener(startAlarm);     handlerButton.setOnClickListener(handler);     asyncButton.setOnClickListener(async);     phoneStateButton.setOnClickListener(phonestate);     callphoneButton.setOnClickListener(callphoneEvent);     vibratorButton.setOnClickListener(vibrator);    }     /**启动服务的事件监听*/    public Button.OnClickListener startService = new Button.OnClickListener(){     public void onClick(View view){       /**单击按钮时启动服务*/      Intent intent = new Intent(MainStadyServics.this,CountService.class);      startService(intent);      Log.v("MainStadyServics", "start Service");     }    };     /**关闭服务*/    public Button.OnClickListener shutdownService = new Button.OnClickListener(){     public void onClick(View view){       /**单击按钮时启动服务*/      Intent intent = new Intent(MainStadyServics.this,CountService.class);       /**退出Activity是，停止服务*/      stopService(intent);      Log.v("MainStadyServics", "shutDown serveice");     }    };     /**打开绑定服务的Activity*/    public Button.OnClickListener startBinderService = new Button.OnClickListener(){     public void onClick(View view){       /**单击按钮时启动服务*/      Intent intent = new Intent(MainStadyServics.this,UseBrider.class);      startActivity(intent);      Log.v("MainStadyServics", "start Binder Service");     }    };     /**打开广播学习的按钮*/    public Button.OnClickListener broadcastReceiver = new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this,UseBroadcast.class);      startActivity(intent);      Log.v("MainStadyServics","start broadcast");     }    };     /**打开通知*/    public Button.OnClickListener notification = new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this, UseNotification.class);      startActivity(intent);      Log.v("MainStadyService ","start Notification");           }    };     /**使用闹钟*/    public Button.OnClickListener startAlarm = new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this, UseAlarmManager.class);      startActivity(intent);      Log.v("MainStadyService ","start alarm");           }    };    public Button.OnClickListener handler= new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this, UseHandleMessage.class);      startActivity(intent);      Log.v("MainStadyService ","start handle");     }    };    public Button.OnClickListener async= new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this, UseAsyncTask.class);      startActivity(intent);      Log.v("MainStadyService ","start handle");     }    };    public Button.OnClickListener phonestate= new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this, UsePhoneState.class);      startActivity(intent);      Log.v("MainStadyService ","start phonestate");     }    };    public Button.OnClickListener callphoneEvent= new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this, UseActionCall.class);      startActivity(intent);      Log.v("MainStadyService ","start callphone");     }    };    public Button.OnClickListener vibrator= new Button.OnClickListener(){     public void onClick(View view){      Intent intent = new Intent(MainStadyServics.this, UseVibrator.class);      startActivity(intent);      Log.v("MainStadyService ","start callphone");     }    };     /***/    protected void onDestroy(){     super.onDestroy();     Intent intent = new Intent(MainStadyServics.this,CountService.class);      /**退出Activity是，停止服务*/     stopService(intent);    }         }

2.启动服务按钮

**这个类实现的是第一个按钮的功能，在这个类中新开了一个线程，并每隔一秒打印出一行日志**

**代码如下：**

package lovefang.stadyService;/**引入包*/ import android.app.Service;// 服务的类 import android.os.IBinder; import android.os.Binder; import android.content.Intent; import android.util.Log;/**计数的服务*/ public class CountService extends Service{   /**创建参数*/  boolean threadDisable ;  int count;    public IBinder onBind(Intent intent){   return null;  }  public void onCreate(){   super.onCreate();    /**创建一个线程，每秒计数器加一，并在控制台进行Log输出*/   new Thread(new Runnable(){    public void run(){     while(!threadDisable){      try{       Thread.sleep(1000);      }catch(InterruptedException e){             }      count++;      Log.v("CountService","Count is"+count);     }    }   }).start();  }  public void onDestroy(){   super.onDestroy();    /**服务停止时，终止计数进程*/   this.threadDisable = true;  }  public int getConunt(){   return count;  }  class ServiceBinder extends Binder{   public CountService getService(){    return CountService.this;   }  } }

3.绑定服务

**服务有两种实现的方法：**

**1.startService，启动服务，这时需要程序员管理服务的生命周期**

**2.bindService，绑定服务，此时Service与Activity绑定在一起**

**下面是实现的代码：**

package lovefang.stadyService;/**引入包*/ import android.app.Activity; import android.content.ComponentName; import android.content.Context; import android.content.Intent; import android.content.ServiceConnection; import android.os.Bundle; import android.os.IBinder; import android.util.Log;/**通过bindService和unBindSerivce的方式启动和结束服务*/ public class UseBrider extends Activity {   /**参数设置*/  CountService countService;   @Override  public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(new UseBriderFace(this));      Intent intent = new Intent(UseBrider.this,CountService.class);       /**进入Activity开始服务*/      bindService(intent, conn, Context.BIND_AUTO_CREATE);        }  private ServiceConnection conn = new ServiceConnection(){    /**获取服务对象时的操作*/    public void onServiceConnected(ComponentName name, IBinder service) {    // TODO Auto-generated method stub    countService = ((CountService.ServiceBinder)service).getService();       }    /**无法获取到服务对象时的操作*/   public void onServiceDisconnected(ComponentName name) {    // TODO Auto-generated method stub    countService =null;   }        };  protected void onDestroy(){   super.onDestroy();   this.unbindService(conn);   Log.v("MainStadyServics", "out");  } }

4.发送广播

**使用sendBroadcast，向一个Action发送广播，并由相应的广播接收器接收并执行相应的动作**

**实现的代码如下：**

**4.1 打开广播服务**

package lovefang.stadyService;/**引入包*/ import android.view.View; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.widget.Button;/**使用Broadcast,这是一个发送广播的类*/ public class UseBroadcast extends Activity{   /**创建参数*/  private Button sendBroadcast;   /**创建Activity*/  public void onCreate(Bundle savedInstanceState){   super.onCreate(savedInstanceState);   setContentView(R.layout.broadcast);// 使用布局文件   getView();   sendBroadcast.setOnClickListener(sendBroadcastClick);// 添加事件监听  }  public void getView(){   sendBroadcast = (Button)findViewById(R.id.sendBroadcast);  }   /**创建事件监听*/  public Button.OnClickListener sendBroadcastClick = new Button.OnClickListener(){   public void onClick(View view){    Intent intent = new Intent();// 创建意图    intent.putExtra("CONTENT",  "This is a Braodcast demo");// 设置广播的内容    intent.setAction("lovefang.stadyService");// 设置广播的Action    sendBroadcast(intent);   }  };   }

**4.2 处理广播消息**

package lovefang.stadyService;/***/ import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.util.Log;/**这是一个接收广播的类*/ public class UseBroadcastReceiver extends BroadcastReceiver{  public void onReceive(Context context, Intent intent){   Log.v("UseBroadcastReceiver", "I get a message");  } }

5.Notification

**这个称之为通知，显示在手机的通知栏，用户可以清除，可以点击**

**实现的代码如下：**

package lovefang.stadyService; import android.content.Intent; import android.os.Bundle; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.net.Uri; import android.media.RingtoneManager; import android.widget.Button; import android.view.View;/**使用notification*/ public class UseNotification extends Activity {   /**创建组件*/  private Button textButton;  private Button soundButton;// 声音通知  private Button vibrateButton;// 震动通知  private Button ledButton;// led通知  private Button offButton;// 关闭通知  NotificationManager notificationManager;   /**创建Activity*/  public void onCreate(Bundle savedInstanceState){   super.onCreate(savedInstanceState);   setContentView(R.layout.notification);   getComment();   registerComment();  }   /**获取对象*/  public void getComment(){    /**获取Notification对象*/   notificationManager = (NotificationManager)this.getSystemService(NOTIFICATION_SERVICE);   textButton = (Button)findViewById(R.id.notificationMessage);   soundButton =(Button)findViewById(R.id.notificationSound);   vibrateButton = (Button)findViewById(R.id.notificationVibrate);   ledButton = (Button)findViewById(R.id.notificationLED);   offButton = (Button)findViewById(R.id.offnotification);  }   /**注册对象*/  public void registerComment(){   textButton.setOnClickListener(notificationMessage);   soundButton.setOnClickListener(notificationSound);   vibrateButton.setOnClickListener(notificationVibrate);   ledButton.setOnClickListener(notificationLed);   offButton.setOnClickListener(notificationOff);  }  public Button.OnClickListener notificationMessage = new Button.OnClickListener(){   public void onClick(View view){    Notification notification = new Notification();// 创建Notification对象    notification.icon = R.drawable.icon;    notification.tickerText = "This is text notication";// 设置通知消息     /**单击通知后的Intent，此例子单击后还是在当前页面*/    PendingIntent intent = PendingIntent     .getActivity(UseNotification.this,       0, new Intent(UseNotification.this,UseNotification.class)       , 0);     /**设置通知消息*/    notification.setLatestEventInfo(UseNotification.this      ,"Notification","Content of Notification Demo",intent);     /**执行通知*/    notificationManager.notify(0, notification);   }  };  public Button.OnClickListener notificationSound = new Button.OnClickListener(){   public void onClick(View view){     /**创建通知对象*/    Notification notification = new Notification();     /**获取系统当前声音*/    String ringName = RingtoneManager.getActualDefaultRingtoneUri(      UseNotification.this, RingtoneManager.TYPE_RINGTONE)      .toString();     /**设置系统当前铃声为此通知的铃声*/    notification.sound = Uri.parse(ringName);     /**执行通知*/    notificationManager.notify(0,notification);   }  };   /**震动通知*/  public Button.OnClickListener notificationVibrate = new Button.OnClickListener(){   public void onClick(View view){    Notification notification = new Notification();// 创建Notification对象    notification.vibrate = new long[] {
        0, 100, 200, 300};// 设置通知震动模式    notificationManager.notify(0,notification);// 执行通知   }  };   /**LED通知*/  public Button.OnClickListener notificationLed = new Button.OnClickListener(){   public void onClick(View view){    Notification notification = new Notification();// 创建Notification对象    notification.ledOnMS = 300;// 设置led开始闪光的时间    notification.ledOffMS = 1000;// 设置关闭时的闪光时间    notificationManager.notify(0,notification);// 执行通知   }  };   /**关闭通知*/  public Button.OnClickListener notificationOff = new Button.OnClickListener(){   public void onClick(View view){    notificationManager.cancel(0);// 关闭通知   }  }; }

6.Alarm

**闹钟服务**

package lovefang.stadyService;import android.app.Activity;import android.os.Bundle;import android.widget.Button;import android.view.View;import android.app.AlarmManager;import java.util.Calendar;public class UseAlarmManager extends Activity {  /**创建参数*/ private Button startAlarm; private Button shutdownAlarm; private AlarmManager alarm;   /**创建Activity*/ public void onCreate(Bundle savedInstanceState){  super.onCreate(savedInstanceState);  setContentView(R.layout.usealarmmanager);  getWidget(); } public void getWidget(){  startAlarm = (Button)findViewById(R.id.startAlarm);  shutdownAlarm = (Button)findViewById(R.id.shutDowntAlarm);  alarm = (AlarmManager)getSystemService(ALARM_SERVICE);// 获取AlarmManager } public void registerWidget(){  startAlarm.setOnClickListener(startAlarms);  shutdownAlarm.setOnClickListener(shutdownAlarms); }  /**启动闹钟*/ public Button.OnClickListener startAlarms = new Button.OnClickListener(){  public void onClick(View view){    // 设置10秒后出发闹钟   Calendar calendar = Calendar.getInstance();   calendar.setTimeInMillis(System.currentTimeMillis());// 设置calendar的时间   calendar.add(Calendar.SECOND, 10);      alarm.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), null);  } }; public Button.OnClickListener shutdownAlarms = new Button.OnClickListener(){  public void onClick(View view){   alarm.cancel(null);  } };}

7.获取手机的状态

**这个功能实现的是获取用户手机的一些定义的信息**

package lovefang.stadyService;/**引入包*/ import android.os.Bundle; import android.app.Activity; import android.app.Service; import android.view.View; import android.widget.Button; import android.widget.TextView; import android.content.ContentResolver;//This class provides applications access to the content model. import android.telephony.TelephonyManager; import android.util.Log;/**获取手机的状态*/ public class UsePhoneState extends Activity{   /**创建参数*/  private ContentResolver cr;  private Button getStateButton;// 用来获取用户的手机状态   /**创建Activity*/  public void onCreate(Bundle savedInstanceState){   super.onCreate(savedInstanceState);   setContentView(R.layout.usephonestate);      cr = getContentResolver();   Log.v("UsePhonestate","cr = getContentResolver()");   Log.v("UsePhonestate","setContentView");   getStateButton = (Button) findViewById(R.id.button_getphonestate);   Log.v("UsePhonestate","getStateButton");   getStateButton.setOnClickListener(getState);   Log.v("UsePhonestate","getStateButton.setOnClickListener");  }  private Button.OnClickListener getState = new Button.OnClickListener(){   public void onClick(View view){     /**获得TelephonyManager对象*/    TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Service.TELEPHONY_SERVICE);     /**获取电信网络级别*/    String teleCode = telephonyManager.getNetworkCountryIso();     /**获取电信网络公司代码*/    String teleComCode = telephonyManager.getNetworkOperator();     /**获取电信网络公司名称*/    String teleComName = telephonyManager.getNetworkOperatorName();     /**获取行动通信类型*/    int TypeCode = telephonyManager.getPhoneType();        String type = "";        switch(TypeCode){     case TelephonyManager.PHONE_TYPE_NONE:      type = "PHONE_TYPE_NONE";      break;     case TelephonyManager.PHONE_TYPE_GSM:      type = "PHONE_TYPE_GSM";      break;     case TelephonyManager.PHONE_TYPE_CDMA:      type = "PHONE_TYPE_CDMA";      break;    }     /**获取网络类型*/    int netTypeCode
