我想在我的应用程序中显示连续通知。
目前我可以在 4 秒后自动发出通知,但我想要的是它应该在特定时间间隔后连续发出。
以下是我的代码。
我的 xml 文件是
<?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="wrap_content"
>
<Button android:id="@+id/notify"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Raise a notification"
android:onClick="notifyMe"
/>
<Button android:id="@+id/cancel"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Clear the notification"
android:onClick="clearNotification"
/>
</LinearLayout>
这是我的活动文件
package com.vimaltuts.android.notificationexample;
import java.util.Timer;
import java.util.TimerTask;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class NotificationExampleActivity extends Activity {
private static final int NOTIFY_ME_ID=1987;
private int count=0;
private NotificationManager mgr=null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mgr=(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
Timer timer = new Timer();
timer.schedule(new TimerTask()
{
public void run()
{
View v = new View(getApplicationContext());
notifyMe(v);
}},4000);
}
@SuppressWarnings("deprecation")
public void notifyMe(View v)
{
@SuppressWarnings("deprecation")
Notification note=new Notification(R.drawable.stat_notify_chat,"Status message!",System.currentTimeMillis());
PendingIntent i=PendingIntent.getActivity(this,0,new Intent(this, NotificationMessage.class),0);
note.setLatestEventInfo(this, "New Email","Unread Conversation", i);
note.number=++count;
note.vibrate=new long[] {500L, 200L, 200L, 500L};
note.flags|=Notification.FLAG_AUTO_CANCEL;
mgr.notify(NOTIFY_ME_ID, note);
}
public void clearNotification(View v) {
mgr.cancel(NOTIFY_ME_ID);
}
}
请告诉我我应该在哪里获得额外的代码(如果有的话)?
也有可能与服务..如何?
我尝试遵循代码敌人测试目的,但它没有用......谁能告诉我哪里出错了
以下是我的活动代码
Intent i= new Intent(NotificationExampleActivity.this,NotificationService.class);
PendingIntent pi=PendingIntent.getService(NotificationExampleActivity.this, 0, i, 0);
AlarmManager alarmMgr=(AlarmManager)getSystemService(ALARM_SERVICE);
alarmMgr.cancel(pi);
alarmMgr.setRepeating(alarmMgr.ELAPSED_REALTIME_WAKEUP, System.currentTimeMillis(),(10*1000), pi);
Toast.makeText(this, "Alarm set", Toast.LENGTH_LONG).show();
以下是我的广播接收器
Toast.makeText(context, "Repeating Alarm worked.", Toast.LENGTH_LONG).show();
我想在一段时间后显示 msg="Repeating Alarm working"
