每日本地通知仅出现一次 - Android

Question

我在YouTube上使用一些教程发出了通知。我以为一切都在起作用，因为我看到了通知。问题是当我在第二天等待通知时。它行不通。它没有出现。

这是一个带有小时等的代码：

button1 = (Button)dialog.findViewById(R.id.btnRegister);
    button1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Calendar calendar = Calendar.getInstance();
            calendar.set(Calendar.HOUR_OF_DAY, 20);
            calendar.set(Calendar.MINUTE, 30);
            calendar.set(Calendar.SECOND, 30);
            Intent intent = new Intent(getApplicationContext(), Notification_receiver.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 100, intent, PendingIntent.FLAG_UPDATE_CURRENT);
            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

哦，它正在开始在我的自定义对话框上使用wiith onclick按钮，该对话仅在第一个应用程序启动下才是apear。请帮助我！

NotificationReceiver Java：

    package com.justfashion;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.graphics.Color;
import android.media.RingtoneManager;
import android.net.Uri;
import android.support.v4.app.NotificationBuilderWithBuilderAccessor;
import android.support.v4.app.NotificationCompat;
/**

public class Notification_receiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
        Intent repeating_intent = new Intent(context,ActivitySplashScreen.class);
        repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(context,100,repeating_intent,PendingIntent.FLAG_UPDATE_CURRENT);
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
                .setContentIntent(pendingIntent)
                .setSmallIcon(android.R.drawable.arrow_up_float)
                .setContentTitle("Hey You!")
                .setSound(Uri.parse("android.resource://" + context.getPackageName()  + "/" + R.raw.sound))
                .setContentText("Collect today's diamonds!")
                .setAutoCancel(true);
        notificationManager.notify(100,builder.build());

    }


}

Answer 1

使用Service类安排您的通知。在此处找到文档-Service |Android开发人员

Answer 2

如果您的应用在此期间重新启动警报被取消。方法是正确的。

enter code here
    public class BootReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        Log.e("BootReceiver","BootReceiver");
        if     (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
            // Set the alarm here.

    }
    }

}
   <receiver android:name=".alarmManager.BootReceiver"
            android:enabled="true">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"></action>
            </intent-filter>
        </receiver>

使用权限：

Answer 3

您已设置的警报尝试这个

alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
    AlarmManager.INTERVAL_DAY, alarmIntent);

如下所述。

Answer 4

在飞溅或主屏幕中实现此功能此方法设置了一天中特定时间的警报。

public void startWeatherAlert() {
        Calendar updateTime = Calendar.getInstance();
        updateTime.setTimeZone(TimeZone.getTimeZone("IST"));
        updateTime.set(Calendar.HOUR_OF_DAY, 8);//set hour of day when you want to trigger
        updateTime.set(Calendar.MINUTE, 15);//set minute of day
        Intent intent = new Intent(this, YourReceiverNameHere.class);//Broadcast receiver here
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, 0);
        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
        alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, updateTime.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);//INTERVAL_DAY means that it will trigger only once in a day.
    }

现在为广播接收器设置

   public class YourReceiverNameHere extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            //your logic here
            //this can be used to invoke service, launch activity or to generate notification
        }
    }

最后在Menifest中注册该广播接收器

<service android:name=".YourReceiverNameHere" />
