Android Service ，在退出程序之后 ，仍然留在后台作为服务项做一些事情，比如说监听用户输入之类的。。。。

这里用来做后台的消息推送，像游戏中的广告可以这么做。

?

Android工程里面有两个Activity、一个Service重写。

MainActivity 是进入游戏的界面。

SecondActivity 是打开通知，点击推送的消息打开的Activity 。

push_service 是重写的Service 。

?

MainActivity

[java]?view plaincopy
  1. package?com.example.androidnotification;??
  2. ??
  3. import?android.os.Bundle;??
  4. import?android.R.integer;??
  5. import?android.app.Activity;??
  6. import?android.app.Notification;??
  7. import?android.app.NotificationManager;??
  8. import?android.app.PendingIntent;??
  9. import?android.content.Context;??
  10. import?android.content.Intent;??
  11. import?android.util.Log;??
  12. import?android.view.Menu;??
  13. import?android.view.View;??
  14. import?android.view.View.OnClickListener;??
  15. import?android.widget.Button;??
  16. ??
  17. public?class?MainActivity?extends?Activity?{??
  18. ??????
  19. ????private?Button?button1;??
  20. ????private?Button?button2;??
  21. ??
  22. ????@Override??
  23. ????protected?void?onCreate(Bundle?savedInstanceState)?{??
  24. ????????super.onCreate(savedInstanceState);??
  25. ????????setContentView(R.layout.activity_main);??
  26. ??????????
  27. ????????//获取到通知管理器??
  28. ????????NotificationManager?mNotificationManager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);??
  29. ??????????
  30. ????????//定义内容??
  31. ????????int?notificationIcon=R.drawable.icon;??

  34. ??????????
  35. ????????Notification?notification=new?Notification(notificationIcon,?notificationTitle,?when);??
  36. ??????????
  37. ????????notification.defaults=Notification.DEFAULT_ALL;??
  38. ??????????
  39. ????????Intent?intent=new?Intent(MainActivity.this,SecondActivity.class);??
  40. ????????PendingIntent?pendingIntent=PendingIntent.getActivity(MainActivity.this,?0,?intent,?0);??
  41. ????????notification.setLatestEventInfo(this,"测试展开title",?"测试展开内容",pendingIntent);??
  42. ??????????
  43. ????????if(notification!=null)??
  44. ????????{??
  45. ????????????Log.e("notifacation",?"notifacation?is?ok");??
  46. ????????????mNotificationManager.notify(1000,?notification);??
  47. ????????}??
  48. ??????????
  49. ????????button1=(Button)findViewById(R.id.button1);??
  50. ????????button1.setOnClickListener(new?OnClickListener()?{??
  51. ??????????????
  52. ????????????@Override??
  53. ????????????public?void?onClick(View?arg0)?{??
  54. ????????????????//?TODO?Auto-generated?method?stub??
  55. ????????????????Intent?pushIntent=new?Intent("com.example.androidnotification.push_service");??
  56. ????????????????startService(pushIntent);??
  57. ??????????????????
  58. ????????????}??
  59. ????????});??
  60. ??????????
  61. ????????button2=(Button)findViewById(R.id.button2);??
  62. ????????button2.setOnClickListener(new?OnClickListener()?{??
  63. ??????????????
  64. ????????????@Override??
  65. ????????????public?void?onClick(View?v)?{??
  66. ????????????????//?TODO?Auto-generated?method?stub??
  67. ????????????????MainActivity.this.finish();??
  68. ????????????}??
  69. ????????});??
  70. ??????????
  71. ????}??
  72. ??
  73. ????@Override??
  74. ????public?boolean?onCreateOptionsMenu(Menu?menu)?{??
  75. ????????//?Inflate?the?menu;?this?adds?items?to?the?action?bar?if?it?is?present.??
  76. ????????getMenuInflater().inflate(R.menu.main,?menu);??
  77. ????????return?true;??
  78. ????}??
  79. ??
  80. }??

打开程序的时候发送了一个通知。。。

主要就是获取到通知管理器然后新建一个通知，然后发送这个通知！。。。

?

?

SecondActivity?

[java]?view plaincopy
  1. package?com.example.androidnotification;??
  2. ??
  3. import?android.app.Activity;??
  4. import?android.os.Bundle;??
  5. ??
  6. public?class?SecondActivity?extends?Activity?{??
  7. ??
  8. ????@Override??
  9. ????protected?void?onCreate(Bundle?savedInstanceState)??
  10. ????{??
  11. ????????super.onCreate(savedInstanceState);??
  12. ????????setContentView(R.layout.secondactivity);??
  13. ????}??
  14. }??

?

第二个Activity只是为了存在而存在，没有啥不懂。。

?

push_service

重写了Service ，注册一个Service 。。

[java]?view plaincopy
  1. package?com.example.androidnotification;??
  2. ??
  3. import?android.app.Activity;??
  4. import?android.app.Notification;??
  5. import?android.app.NotificationManager;??
  6. import?android.app.PendingIntent;??
  7. import?android.app.Service;??
  8. import?android.content.Context;??
  9. import?android.content.Intent;??
  10. import?android.os.Handler;??
  11. import?android.os.IBinder;??
  12. import?android.util.Log;??
  13. ??
  14. public?class?push_service?extends?Service?{??
  15. ??
  16. ????@Override??
  17. ????public?IBinder?onBind(Intent?arg0)?{??
  18. ????????//?TODO?Auto-generated?method?stub??
  19. ????????return?null;??
  20. ????}??
  21. ??????
  22. ????@Override??
  23. ????public?void?onCreate()??
  24. ????{??
  25. ????????super.onCreate();??
  26. ????????Log.i("push_service",?"push_service?onCreate");??
  27. ????}??
  28. ??????
  29. ????@SuppressWarnings("deprecation")??
  30. ????@Override??
  31. ????public?void?onStart(Intent?intent,int?startId)??
  32. ????{??
  33. ????????super.onStart(intent,?startId);??
  34. ????????Log.i("push_service",?"push_service?start");??
  35. ??????????
  36. ????????new?Thread(new?Runnable()?{??
  37. ??????????????
  38. ????????????@Override??
  39. ????????????public?void?run()?{??
  40. ????????????????//?TODO?Auto-generated?method?stub??
  41. ????????????????try?{??

  75. ????????????????????e.printStackTrace();??

  80. ????}??
  81. ??????
  82. ????@Override??

  85. ????????super.onDestroy();??
  86. ????????Log.i("push_service",?"push_service?destroy");??
  87. ????}??
  88. ??
  89. }??

嗯，把发送通知的代码复制到这里循环几百次。。用来测试退出程序后服务是不是还在跑着。
