How to open activity that corresponding to the position click when I clicked on the notification when pops up?

I have RecyclerView that contains notes, when I add new note I want to add reminder for that particular note but when the notification appears and I click on it I want to navigate to that activity and open that note. Notification works properly but what I want is, when I clicked on the notification open that note I set reminder on it.
AlarmReceiver class:
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, ChecklistChildActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, i, 0);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "alarmChannel")
.setContentTitle("title")
.setContentText("text")
.setAutoCancel(true)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setSmallIcon(R.drawable.alarm)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setContentIntent(pendingIntent);
NotificationManagerCompat managerCompat = NotificationManagerCompat.from(context);
managerCompat.notify(123, builder.build());
}
}
setAlarm method:
private void setAlarm() {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR, hour);
calendar.set(Calendar.MINUTE, minute);
alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
Toast.makeText(this, "Alarm is set", Toast.LENGTH_SHORT).show();
}
I have an o'clock interface in RecyclerAdapter that I implemented in MainActivity:
#Override
public void onNoteClicked(int position, View itemView) {
Intent intent = new Intent(this, NoteDetail.class).setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("id", noteAdapter.itemList.get(position).getId());
intent.putExtra("title", noteAdapter.itemList.get(position).getTitle());
intent.putExtra("content", noteAdapter.itemList.get(position).getContent());
intent.putExtra("date", noteAdapter.itemList.get(position).getDate());
intent.putExtra("backgroundColor", noteAdapter.itemList.get(position).getBackgroundColor());
startActivity(intent);
}
When I clicked on the notification this method somehow should be called. When I add the note I don't know which position it goes in order to pass that position with the intent, though if I know the position, the position may change when I add or remove another note.

Great, I have an idea, I assume your activity gets id and other data from intent. so we have to put data to alarm intent and read them from AlarmReceiver and put them again into the Activity Intent.
private void setAlarm() {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR, hour);
calendar.set(Calendar.MINUTE, minute);
alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(this, AlarmReceiver.class);
intent.putExtra("id", "myId");
intent.putExtra("title", "my title");
pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
Toast.makeText(this, "Alarm is set", Toast.LENGTH_SHORT).show();
}
and get that from the Receiver class:
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, ChecklistChildActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.putExtra("id", intent.getStringExtra("id"));
i.putExtra("title", intent.getStringExtra("title"));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, i, 0);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context, "alarmChannel")
.setContentTitle("title")
.setContentText("text")
.setAutoCancel(true)
.setDefaults(NotificationCompat.DEFAULT_ALL)
.setSmallIcon(R.drawable.alarm)
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setContentIntent(pendingIntent);
NotificationManagerCompat managerCompat = NotificationManagerCompat.from(context);
managerCompat.notify(123, builder.build());
}
that is a simple way but I suggest using the database in your activity and getting the note details in the onCreate method with id, so you need just add id in your intents and add get query in NoteDetail.java class.

How can I know which button was clicked in the notification?

I am developing an application, I have 2 buttons in an on the notification. How can I know which button the user has clicked?
This my Notification codes;
public void NotificationSettings(Context context){
Intent stateIntent = new Intent(context, MyBroadcastReceiver.class);
stateIntent.putExtra("id", 100);
PendingIntent pendingIntent =
PendingIntent.getBroadcast(context, 0, stateIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder = new NotificationCompat.Builder(context, "access2020")
.setSmallIcon(R.drawable.ic_baseline_add_alert_24)
.setContentTitle("Academy Notification")
.setContentText("Hey this is an important notifications")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.addAction(R.drawable.ic_baseline_add_alert_24, "Set Active", pendingIntent)
.addAction(R.drawable.ic_baseline_add_alert_24,"Dismiss", pendingIntent);
notificationManager = NotificationManagerCompat.from(context);
}
and My Broadcast
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "test", Toast.LENGTH_SHORT).show();
int notificationId = intent.getIntExtra("id", 0);
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
notificationManager.cancel(notificationId);
}

You should pass an identifier to the intent as an extra and then retrieve in your BroadcastReceiver.
public void NotificationSettings(Context context){
// put an extra identifier for Set Active Action
Intent setActiveStateIntent = new Intent(context, MyBroadcastReceiver.class);
setActiveStateIntent.putExtra("id", 100);
setActiveStateIntent.putExtra("action", "Action.SetActive");
PendingIntent setActivePendingIntent =
PendingIntent.getBroadcast(context, 0, setActiveStateIntent, PendingIntent.FLAG_UPDATE_CURRENT);
// put an extra identifier for Dismiss
Intent dismissStateIntent = new Intent(context, MyBroadcastReceiver.class);
dismissStateIntent.putExtra("id", 100);
dismissStateIntent.putExtra("action", "Action.Dismiss");
PendingIntent dismissPendingIntent =
PendingIntent.getBroadcast(context, 0, dismissStateIntent, PendingIntent.FLAG_UPDATE_CURRENT);
builder = new NotificationCompat.Builder(context, "access2020")
.setSmallIcon(R.drawable.ic_baseline_add_alert_24)
.setContentTitle("Academy Notification")
.setContentText("Hey this is an important notifications")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.addAction(R.drawable.ic_baseline_add_alert_24, "Set Active", setActivePendingIntent)
.addAction(R.drawable.ic_baseline_add_alert_24,"Dismiss", dismissPendingIntent);
notificationManager = NotificationManagerCompat.from(context);
}
Then in your BroadcastReceiver you can do the following:
public void onReceive(Context context, Intent intent) {
if(intent.getStringExtra("action").equals("Action.Dismiss")) {
// perform your dismiss action
} else if (intent.getStringExtra("action").equals("Action.SetActive")) {
// perform your set active logic
} else {
// handle invalid action
}
}

I solved with this way but still i am not sure it is the right way
public void NotificationSettings(Context context){
Intent stateIntent0 = new Intent(context, MyBroadcastReceiver.class);
Intent stateIntent1 = new Intent(context, MyBroadcastReceiver.class);
stateIntent0.putExtra("id", 100);
stateIntent1.putExtra("id", 200);
PendingIntent pendingIntent0 =
PendingIntent.getBroadcast(context, 0, stateIntent0, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent pendingIntent1 =
PendingIntent.getBroadcast(context, 1, stateIntent1, PendingIntent.FLAG_UPDATE_CURRENT);
builder = new NotificationCompat.Builder(context, "lemubitA")
.setSmallIcon(R.drawable.ic_baseline_add_alert_24)
.setContentTitle("Lemubit Academy Notification")
.setContentText("Hey this is an important notifications")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.addAction(R.drawable.ic_baseline_add_alert_24, "Set Active", pendingIntent0)
.addAction(R.drawable.ic_baseline_add_alert_24,"Dismiss", pendingIntent1);
notificationManager = NotificationManagerCompat.from(context);
}
AND this my Broadcast
int notificationId = intent.getIntExtra("id", 0);
Toast.makeText(context, notificationId+"", Toast.LENGTH_SHORT).show();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);
notificationManager.cancel(notificationId);

Setting some notifications with AlarmManager and cancelling one of them

in my program i set notifications with a string and its clock to get a notification with that string at its clock.(I mean user wants to get a notification with a string at demanding time, and user gave me a lot of strings and their clocks.) And if the user want to cancel that notification i don't know how to do it.
I tried alarmManager.cancel(pendingIntent) but I want to cancel the only one notification not all of them. Also, it doesn't cancel any notification too.
here is the code in the main
public void gecikmeliGoster(String plan, int yil, int ay, int gun, String saat){
NotificationCompat.Builder builder;
NotificationManager bildirimYoneticisi = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
Intent ıntent = new Intent(HatirlaticiKur.this, AlarmReciever.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("Hatırlatıcı")
.setContentText(plan)
.setSmallIcon(R.drawable.hatirlatici)
.setAutoCancel(true)
.setContentIntent(gidilecekIntent);
} else {
builder = new NotificationCompat.Builder(this);
builder.setContentTitle("Hatırlatıcı")
.setContentText(plan)
.setSmallIcon(R.drawable.hatirlatici)
.setContentIntent(gidilecekIntent)
.setAutoCancel(true)
.setPriority(Notification.PRIORITY_HIGH);
}
Intent broadcastIntent = new Intent(HatirlaticiKur.this, AlarmReciever.class);
broadcastIntent.putExtra("nesne", builder.build());
PendingIntent gidilecekBroadcast = PendingIntent.getBroadcast(this, 0, broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
//long gecikme = SystemClock.elapsedRealtime() + 5000; //bu 5 saniyede bir bildirim gelmesi için falan
String[] noktasiz = saat.split(":");
int akrep = Integer.parseInt(noktasiz[0]);
int yelkovan = Integer.parseInt(noktasiz[1]);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.YEAR, yil);
calendar.set(Calendar.MONTH, ay);
calendar.set(Calendar.DATE, gun);
calendar.set(Calendar.HOUR_OF_DAY, akrep);
calendar.set(Calendar.MINUTE, yelkovan);
calendar.set(Calendar.SECOND, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 0, gidilecekBroadcast);
}
and here is the code in AlarmReceiver
public class AlarmReciever extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationManager bildirimYoneticisi = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
Notification bildirim = intent.getParcelableExtra("nesne");
bildirimYoneticisi.notify(1,bildirim);
}
}
I want to cancel demanding notifications, i will appreciate your help

use used 0 id for setting alarm
PendingIntent gidilecekBroadcast = PendingIntent.getBroadcast(this, 0, broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
You need uniqueid for all notification set using alarmmanager
then based on uniqueid you can cancel alarm
PendingIntent gidilecekBroadcast =
PendingIntent.getBroadcast(getApplicationContext(), uniqueid , broadcastIntent,
PendingIntent.FLAG_UPDATE_CURRENT)
alarmManager.cancel(gidilecekBroadcast);

Getting trouble to show birthday reminder

My application contains a SQLite database to store a person's information.
I store birthday as a long value. I want to show notification if someone has birthday today in the saved list. I am retrieving the long birthday value, setting it to a calendar and comparing it with current calendar month and day. But the problem is if someone has birthday matching with current day the the notification arises but shows that it is the birthday of the last person in the list whatever be the birthday of the last person. Please help. Thanks in advance.
Here are the codes
calendar_now = Calendar.getInstance();
calendar_now.setTimeInMillis(System.currentTimeMillis());
int month_now = calendar_now.get(Calendar.MONTH);
int day_now = calendar_now.get(Calendar.DAY_OF_MONTH);
//Set a specific time to the calendar
calendar_now.set(Calendar.HOUR_OF_DAY, 6);
calendar_now.set(Calendar.MINUTE, 0);
calendar_now.set(Calendar.SECOND, 0);
dbHelper = new DbHelper(this);
personArrayList = dbHelper.getPerson();
birth_calendar = Calendar.getInstance();
for (Person p : personArrayList) {
name = p.getName(); //Get the person's name
mobile = p.getMobile();
byte_image = p.getByteImage();
position = personArrayList.indexOf(p);
DoB = p.getDateOfBirth();
birth_calendar.setTimeInMillis(DoB);
int birth_month = birth_calendar.get(Calendar.MONTH);
int birthday = birth_calendar.get(Calendar.DAY_OF_MONTH);
if ((birth_month == month_now) && (birthday == day_now)) {

alarmManager.setExact(AlarmManager.RTC_WAKEUP, calendar_now.getTimeInMillis(), pendingIntent);
} else {
Toast.makeText(this, "No birthday today", Toast.LENGTH_SHORT).show();
}
birth_calendar.clear();
}
NotificationReceiver.java
public class NotificationReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationManager notificationManager = (NotificationManager)
context.getSystemService(Context.NOTIFICATION_SERVICE);
//Open PersonDetailsActivity on notification click

Replace your code with this.

Set Notification to a specific time

I want to set a notification to be shown in a specific time, like 10AM. I already searched this the web and did this, but I don't know what is wrong cause nothing is notifying! Here are my notification class:
public class notification extends AppCompatActivity {
NotificationManager manager;
Notification myNotication;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_notification);
manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Intent intent = new Intent(notification.this,about.class);
PendingIntent pendingIntent = PendingIntent.getActivity(notification.this, 1, intent, 0);
Notification.Builder builder = new Notification.Builder(notification.this);
builder.setAutoCancel(false);
builder.setTicker("this is ticker text");
builder.setContentTitle("WhatsApp Notification");
builder.setContentText("You have a new message");
builder.setSmallIcon(R.drawable.up);
builder.setContentIntent(pendingIntent);
builder.setOngoing(true);
builder.setNumber(100);
myNotication = builder.getNotification();
manager.notify(0, myNotication);
}
And my main class(activity)(onCreate method):
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
alarmMgr0 = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(main.this,notification.class);
intent.putExtra("uur", "1e");
pendingIntent = PendingIntent.getBroadcast(main.this, 0, intent, 0);
timeOff9 = Calendar.getInstance();
timeOff9.set(Calendar.HOUR_OF_DAY, 01);
timeOff9.set(Calendar.MINUTE, 46);
timeOff9.set(Calendar.SECOND, 0);
alarmMgr0.set(AlarmManager.RTC_WAKEUP, timeOff9.getTimeInMillis(), pendingIntent);

i think you should modify this below code as your requirement
private void handleNotification() {
Intent alarmIntent = new Intent(this, AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 5000, pendingIntent);
}
and This is custom BroadcastReceiver
public class AlarmReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Calendar now = GregorianCalendar.getInstance();
int dayOfWeek = now.get(Calendar.DATE);
if(dayOfWeek != 1 && dayOfWeek != 7) {
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle(context.getResources().getString(R.string.message_box_title))
.setContentText(context.getResources().getString(R.string.message_timesheet_not_up_to_date));
Intent resultIntent = new Intent(context, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(1, mBuilder.build());
}
}
}
And add manifest application tag:
<receiver
android:name="be.menis.timesheet.service.AlarmReceiver"
android:process=":remote" />
modify this code as your need i think this is useful
