Question

我在Youtube上发了一些教程通知。我认为一切正常，因为我看到了通知。问题是我在第二天等待通知。它不起作用。它没有出现。

这是一个带小时等的代码：

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，它开始在我的自定义对话框上使用onclick按钮，该按钮仅在第一次启动应用程序时出现。请帮帮我们！

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课程安排通知。在此处查找文档 - Service | Android Developers

Answer 2

如果你的应用程序在此期间重新启动，警报会被取消。所以在另一天没有通知。所以使用广播接收器解决这个问题。请不要使用服务只显示通知。你的方法是正确的。

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

您设置的闹钟可能出现问题试试这个

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

如上所述[{3}}和here。

Answer 4

在启动画面或主屏幕中实现此功能此方法为特定时间设置警报。

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.
    }

现在设置广播接收器

   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
        }
    }

最后在清单中注册该广播接收器

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

每日本地通知只会出现一次 - Android
