Java代码:

public class main extends Activity {    /** Called when the activity is first created. */int notification_id=19172439;NotificationManager nm;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        nm=(NotificationManager)getSystemService(NOTIFICATION_SERVICE);        Button bt1=(Button)findViewById(R.id.bt1);        bt1.setOnClickListener(bt1lis);        Button bt2=(Button)findViewById(R.id.bt2);        bt2.setOnClickListener(bt2lis);            }    OnClickListener bt1lis=new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stubshowNotification(R.drawable.home,"图标边的文字","标题","内容");}        };    OnClickListener bt2lis=new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stub//showNotification(R.drawable.home,"图标边的文字","标题","内容");nm.cancel(notification_id);}        };    public void showNotification(int icon,String tickertext,String title,String content){    //设置一个唯一的ID,随便设置        //Notification管理器    Notification notification=new Notification(icon,tickertext,System.currentTimeMillis());    //后面的参数分别是显示在顶部通知栏的小图标,小图标旁的文字(短暂显示,自动消失)系统当前时间(不明白这个有什么用)    notification.defaults=Notification.DEFAULT_ALL;     //这是设置通知是否同时播放声音或振动,声音为Notification.DEFAULT_SOUND    //振动为Notification.DEFAULT_VIBRATE;    //Light为Notification.DEFAULT_LIGHTS,在我的Milestone上好像没什么反应    //全部为Notification.DEFAULT_ALL    //如果是振动或者全部,必须在AndroidManifest.xml加入振动权限    PendingIntent pt=PendingIntent.getActivity(this, 0, new Intent(this,main.class), 0);    //点击通知后的动作,这里是转回main 这个Acticity    notification.setLatestEventInfo(this,title,content,pt);    nm.notify(notification_id, notification);        }}

xml:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    ><Button android:id="@+id/bt1"android:layout_height="wrap_content"android:layout_width="fill_parent"android:text="Notification测试"/><Button android:id="@+id/bt2"android:layout_height="wrap_content"android:layout_width="fill_parent"android:text="清除Notification"/></LinearLayout>
