本文介绍了如何创建它，即使在应用程序关闭，每隔30秒显示状态栏通知的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我要创建一个显示每30秒，即使在应用程序关闭状态栏通知。我已经搜索并实施了很多建议，但没有一个似乎工作。我能够创建通知，但是当我的应用程序没有运行，不显示任何通知。我不希望我的应用程序运行时要显示的通知。下面是我的code创建通知：
MainActivity.class：
私人无效showNotification（）{
// code的通知 意图resultIntent =新意图（这一点，ResultActivity.class）;
TaskStackBuilder stackBuilder = TaskStackBuilder.create（本）;
//添加后退堆栈的意图（而不是意图本身）
stackBuilder.addParentStack（ResultActivity.class）;
//添加启动该活动到堆栈的顶部的意图
stackBuilder.addNextIntent（resultIntent）;
的PendingIntent resultPendingIntent = stackBuilder.getPendingIntent（0，PendingIntent.FLAG_UPDATE_CURRENT）; 通知通知=新Notification.Builder（本）
.setSmallIcon（R.drawable.image1）
.setContentTitle（时代）
.setContentText（剩余时间）
.setContentIntent（resultPendingIntent）
.addAction（R.drawable.logo，查看，resultPendingIntent）
。建立（）;
NotificationManager notificationManager =（NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）;
notification.flags | = Notification.FLAG_AUTO_CANCEL
notificationManager.notify（0，通知）;
}
私人无效doTheAutoRefresh（）{
handler.postDelayed（新的Runnable（）{
公共无效的run（）{
}
}，30000）;
}@覆盖
保护无效的onStop（）{
super.onStop（）;
showNotification（）;
doTheAutoRefresh（）;
}
解决方案
我不得不提的充分通知code。试试这个code。
1]声明服务开始启动画面
//这是飞溅活动电话
新的ServiceManager（）开始（Splash.this）;
2]制作的ServiceManager类
公共类的ServiceManager {私人AlarmManager amPMR = NULL;
私人的PendingIntent piPMR = NULL;
公共无效启动（上下文的背景下）{ Log.print（startBGProcesses的ServiceManager ::）; 如果（！AlarmReceiver.STARTED）{
//叫醒服务
amPMR =（AlarmManager）上下文
.getSystemService（Context.ALARM_SERVICE）;
意图intentPMR =新意图（背景下，AlarmReceiver.class）;
piPMR = PendingIntent.getBroadcast（上下文，0，intentPMR，0）;
amPMR.setRepeating（AlarmManager.RTC_WAKEUP，
System.currentTimeMillis的（），（60000 * 1），piPMR）;
}}
}
3]让AlarmReceiver类
公共类AlarmReceiver扩展广播接收器{公共静态布尔已启动= FALSE;私人长期currentMiliSec;@覆盖
公共无效的onReceive（上下文的背景下，意图意图）{ AlarmReceiver.STARTED = TRUE; Log.print（AlarmReceiver.class +，AlarmReceiver）;
this.doProcess（上下文）;
}公共无效doProcess（上下文的背景下）{
//调用自定义通知功能
意图intentNoti =新意图（背景下，Dashboard.class）;
Creating_Custom_Notification_Layout（背景下，标题，
字幕，
intentNoti）;
}
}
4]让你的自定义通知功能和custom_notification.xml文件。
公共静态无效Creating_Custom_Notification_Layout（上下文mContext，
标题字符串，字符串MESG，意图ActionIntent）{ // INT ISSUE_ID = ActionIntent.getIntExtra（Const.ISSUE_ID，0）; 字符串NS = Context.NOTIFICATION_SERVICE;
NotificationManager nManager =（NotificationManager）mContext
.getSystemService（纳秒）; nManager.cancel（0）;
// RemoteViews对象传递给通知的内容查看
//字段。
//所以没有必要使用setLatestEventInfo INT图标= R.drawable.ic_launcher; // ic_stat_gcm;
// CharSequence的tickerText =我的Custome的通知;
时长= System.currentTimeMillis的（）; 通知通知=新的通知（图标，MESG时）; notification.defaults = Notification.DEFAULT_VIBRATE
| Notification.DEFAULT_SOUND; 使用远程视窗通知// 1，创建自定义布局
// 2.RemoteViews膨胀的自定义布局，并传递到的内容查看您的
//通知
// 3.See的custom_notification然后
// 4.使用RemoveViews方法来定义图像和文本。
// 5.Then传递RemoteViews对象的的内容查看现场
//通知，如显示在下面 RemoteViews内容查看=新的RemoteViews（mContext.getPackageName（）
R.layout.custom_notification）;
contentView.setTextViewText（R.id.NotoficationTitle，职称）;
contentView.setTextViewText（R.id.text，MESG）; notification.contentView =内容查看; 意图notificationIntent =新的Intent（）;
notificationIntent = ActionIntent; 的PendingIntent mPendingIntent = PendingIntent.getActivity（mContext，0，
notificationIntent，
notification.flags | = Notification.FLAG_AUTO_CANCEL
| Notification.FLAG_SHOW_LIGHTS）; // PendingIntent.FLAG_CANCEL_CURRENT）; //通未决意图内容意图通知意向
notification.contentIntent = mPendingIntent; //设置通知通知经理
nManager.notify（0，通知）;
}
5]在声明Manifest.xml文件接收器的名称
＆lt;用途..
＆lt;接收机器人：名字=com.services.AlarmReceiver/＆GT;
＆LT; /用途＆gt;
我希望这充分code帮助你..谢谢..：）
I want to create a status bar notification which is displayed every 30 seconds even when the application is closed. I have searched and implemented many suggestions but none seems to work. I am able to create notification but when my application is not running, no notifications are displayed. I don't want the notifications to be displayed when my application is running. Below is my code for creating the notification:
MainActivity.class:
private void showNotification(){
//Code for Notification
Intent resultIntent = new Intent(this, ResultActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
// Adds the back stack for the Intent (but not the Intent itself)
stackBuilder.addParentStack(ResultActivity.class);
// Adds the Intent that starts the Activity to the top of the stack
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0,PendingIntent.FLAG_UPDATE_CURRENT);
Notification notification=new Notification.Builder(this)
.setSmallIcon(R.drawable.image1)
.setContentTitle("Time")
.setContentText("Time left")
.setContentIntent(resultPendingIntent)
.addAction(R.drawable.logo, "View", resultPendingIntent)
.build();
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notification.flags |= Notification.FLAG_AUTO_CANCEL
notificationManager.notify(0, notification);
}
private void doTheAutoRefresh() {
handler.postDelayed(new Runnable() {
public void run() {
}
}, 30000);
}
@Override
protected void onStop() {
super.onStop();
showNotification();
doTheAutoRefresh();
}
解决方案
I have mention full code of notification. Try this Code.
1] Declare Services start on splash Screen
//This is call on splash activity
new ServiceManager().start(Splash.this);
2] Make ServiceManager class
public class ServiceManager {
private AlarmManager amPMR = null;
private PendingIntent piPMR = null;
public void start(Context context) {
Log.print("startBGProcesses ServiceManager :: ");
if (!AlarmReceiver.STARTED) {
// Wake up Service
amPMR = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent intentPMR = new Intent(context, AlarmReceiver.class);
piPMR = PendingIntent.getBroadcast(context, 0, intentPMR, 0);
amPMR.setRepeating(AlarmManager.RTC_WAKEUP,
System.currentTimeMillis(), (60000 * 1), piPMR);
}
}
}
3] Make AlarmReceiver Class
public class AlarmReceiver extends BroadcastReceiver {
public static boolean STARTED = false;
private Long currentMiliSec;
@Override
public void onReceive(Context context, Intent intent) {
AlarmReceiver.STARTED = true;
Log.print(AlarmReceiver.class + "", "AlarmReceiver");
this.doProcess(context);
}
public void doProcess(Context context) {
//Call your custom Notification function
Intent intentNoti = new Intent(context,Dashboard.class);
Creating_Custom_Notification_Layout(context, "Title",
"SubTitle",
intentNoti);
}
}
4] Make your custom notification function and "custom_notification.xml" file.
public static void Creating_Custom_Notification_Layout(Context mContext,
String title, String mesg, Intent ActionIntent) {
// int ISSUE_ID = ActionIntent.getIntExtra(Const.ISSUE_ID, 0);
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager nManager = (NotificationManager) mContext
.getSystemService(ns);
nManager.cancel(0);
// RemoteViews object is passed to the Notification in the contentView
// field.
// so no need to use setLatestEventInfo
int icon = R.drawable.ic_launcher;// ic_stat_gcm;
// CharSequence tickerText = "My Custome notification";
long when = System.currentTimeMillis();
Notification notification = new Notification(icon, mesg, when);
notification.defaults = Notification.DEFAULT_VIBRATE
| Notification.DEFAULT_SOUND;
// 1.create custom layout of notification using RemoteView
// 2.RemoteViews inflate custom layout and pass to contentView of your
// notification
// 3.See the custom_notification then
// 4.use the RemoveViews methods to define the image and text.
// 5.Then pass the RemoteViews object to the contentView field of the
// Notification, as show in below
RemoteViews contentView = new RemoteViews(mContext.getPackageName(),
R.layout.custom_notification);
contentView.setTextViewText(R.id.NotoficationTitle, title);
contentView.setTextViewText(R.id.text, mesg);
notification.contentView = contentView;
Intent notificationIntent = new Intent();
notificationIntent = ActionIntent;
PendingIntent mPendingIntent = PendingIntent.getActivity(mContext, 0,
notificationIntent,
notification.flags |= Notification.FLAG_AUTO_CANCEL
| Notification.FLAG_SHOW_LIGHTS);// PendingIntent.FLAG_CANCEL_CURRENT);
// pass pending intent to content intent to notification intent
notification.contentIntent = mPendingIntent;
// set notification to notification manager
nManager.notify(0, notification);
}
5] Declare receiver name on Manifest.xml file
<application..
<receiver android:name="com.services.AlarmReceiver" />
</application>
I hope this full code help for you.. Thanks.. :)
