所以我有这个代码
public class notif extends Activity {
private static final int NOTIFY_ME_ID=1337;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final NotificationManager mgr=(NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification note=new Notification(R.drawable.icon,"New Problem ",System.currentTimeMillis());
note.flags|=Notification.FLAG_AUTO_CANCEL;
PendingIntent i=PendingIntent.getActivity(this, 0,new Intent(this,list.class), 0);
note.setLatestEventInfo(this,"Problem Occured","Click to see the problem",i);
mgr.notify(NOTIFY_ME_ID,note);
}
此代码是关于发送通知但我希望它只显示在我的通知顶部而不是首先打开任何页面，所以它就像通知可以出现在主菜单中而不首先打开任何页面像。短信通知只显示在顶部而不必查看整个短信，直到我们点击通知，所以有人可以帮我这个吗？ ：）

Create a class NotificationAlert and paste the code below there:
import android.os.Bundle;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
public class NotificationAlert extends Activity {
private static final int NOTIFY_ME_ID=1337;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.notification_alert);
/*********** Create notification ***********/
final NotificationManager mgr=
(NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification note=new Notification(R.drawable.stat_notify_chat,
"Android Example Status message!",
System.currentTimeMillis());
// This pending intent will open after notification click
PendingIntent i=PendingIntent.getActivity(this, 0,
new Intent(this, NotifyMessage.class),
0);
note.setLatestEventInfo(this, "Android Example Notification Title",
"This is the android example notification message", i);
//After uncomment this line you will see number of notification arrived
//note.number=2;
mgr.notify(NOTIFY_ME_ID, note);
}
}
Create a class NotifyMessage and paste the code below there:
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class NotifyMessage extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView txt=new TextView(this);
txt.setText("Activity after click on notification");
setContentView(txt);
}
}

我想我现在知道我必须使用服务，这是制作该服务的代码希望它有助于其他
public class servicenotif extends Service {
private static final String TAG = "servicenotif";
