MainActivity.java

package com.info.alarmtetiklemebildirim2018;

import android.app.Activity;
import android.app.AlarmManager;
import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.TimePickerDialog;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.os.SystemClock;
import android.support.v4.app.NotificationCompat;
import android.view.View;
import android.widget.Button;
import android.widget.TimePicker;

import java.util.Calendar;

public class MainActivity extends Activity {

private Calendar calendar;
private Button buttonBildirimGonder;
private TimePickerDialog timePickerDialog;

@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());

timePickerDialog = new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {
@override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

calendar.set(Calendar.HOUR_OF_DAY,hourOfDay);
calendar.set(Calendar.MINUTE,minute);


}
}, Calendar.HOUR_OF_DAY, Calendar.MINUTE, true);

buttonBildirimGonder = (Button) findViewById(R.id.buttonBildirimGonder);


buttonBildirimGonder.setOnClickListener(new View.OnClickListener() {
@override
public void onClick(View v) {

zamanliliBildirimGonder();
}
});


}


private void zamanliliBildirimGonder() {

NotificationCompat.Builder builder;

NotificationManager bildirimYoneticisi =
(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

Intent ıntent = new Intent(this,MainActivity.class);

PendingIntent gidilecekIntent = PendingIntent.getActivity(this,1,ıntent,PendingIntent.FLAG_UPDATE_CURRENT);


if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

String kanalId = "kanalId";
String kanalAd = "kanalAd";
String kanalTanım = "kanalTanım";
int kanalOnceligi = NotificationManager.IMPORTANCE_HIGH;

NotificationChannel kanal = bildirimYoneticisi.getNotificationChannel(kanalId);

if (kanal == null) {
kanal = new NotificationChannel(kanalId, kanalAd, kanalOnceligi);
kanal.setDescription(kanalTanım);
bildirimYoneticisi.createNotificationChannel(kanal);
}

builder = new NotificationCompat.Builder(this, kanalId);

builder.setContentTitle("Başlık")
.setContentText("İçerik")
.setSmallIcon(R.drawable.resim)
.setAutoCancel(true)
.setContentIntent(gidilecekIntent);

} else {

builder = new NotificationCompat.Builder(this);

builder.setContentTitle("Başlık")
.setContentText("İçerik")
.setSmallIcon(R.drawable.resim)
.setContentIntent(gidilecekIntent)
.setAutoCancel(true)
.setPriority(Notification.PRIORITY_HIGH);
}


Intent broadcastIntent =
new Intent(MainActivity.this,BildirimYayinlayici.class);

broadcastIntent.putExtra("bildirimNesnesi",builder.build());

PendingIntent gidilecekBroadcast = PendingIntent.getBroadcast(this
,0
,broadcastIntent
,PendingIntent.FLAG_UPDATE_CURRENT);

AlarmManager alarmManager =
(AlarmManager) getSystemService(Context.ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),gidilecekBroadcast);



}

import android.app.Notification;
import android.app.NotificationManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class BildirimYayinlayici extends BroadcastReceiver {

public void onReceive(Context context, Intent intent) {

NotificationManager bildirimYoneticisi = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

Notification bildirim = intent.getParcelableExtra("bildirimNesnesi");

bildirimYoneticisi.notify(1, bildirim);
