There are many fragments in the app like fragmentA, fragmentB and fragmentC. When the app is showing fragmentB and a user clicks on the delete button on the notification, a dialog box appears on fragmentB that is working properly but when the app is showing fragmentB and the user puts the app in the background and clicks on the delete button on the notification the dialog box appears on the home screen or on other apps which is on the foreground. In this case, the dialog box should appear on fragmentB (the last opened screen/fragment) and the app should come in the foreground. Please note that this fragmentB is not specific it can be any fragment.
I have written the following code showing notification in fragmentB:
// Create an explicit intent for an activity in this app
val intent = Intent(requireContext(),DialogActivity::class.java)
intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_SINGLE_TOP
val pendingIntent = PendingIntent.getActivity(requireContext(),0,intent,0)
val deleteIntent = Intent(this,BharosaBroadcastReceiver::class.java)
deleteIntent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_SINGLE_TOP
deleteIntent.apply {
action = "Delete"
putExtra("UserId","100")
putExtra("notificationId",notificationId)
}
val deletePendingIntent = PendingIntent.getBroadcast(this,0,deleteIntent,0)
var btn : Button = findViewById(R.id.btn)
btn.setOnClickListener{
val contentView = RemoteViews(packageName, R.layout.custom_push)
contentView.setImageViewResource(R.id.image, R.mipmap.ic_launcher)
contentView.setTextViewText(R.id.title, "Hello World")
contentView.setTextViewText(R.id.text, "Please click the delete btton to delete")
val notificationBuilder = NotificationCompat.Builder(this,channelId)
.setSmallIcon(R.drawable.ic_action_info)
.setColor(Color.GREEN)
.setCustomContentView(contentView)
.setCustomBigContentView(contentView)
.setStyle(NotificationCompat.DecoratedCustomViewStyle())
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setCategory(NotificationCompat.CATEGORY_MESSAGE)
.setFullScreenIntent(pendingIntent, true)
.setOngoing(true)
contentView.setOnClickPendingIntent(R.id.delete, pendingIntent)
with(NotificationManagerCompat.from(this)){
notify(notificationId, notificationBuilder.build())
}
}
The code of BroadcastReceiver is as follows:
class BharosaBroadcastReceiver(): BroadcastReceiver(){
companion object {
var isDeletedClicked = false
}
override fun onReceive(context: Context?, intent: Intent?) {
intent?.apply {
try {
val notificationId = getIntExtra("notificationId",0)
var dialog = AlertDialog.Builder(context)
dialog.setTitle("Hello!")
dialog.setMessage("Do you want to delete it")
dialog.setPositiveButton("Delete",
DialogInterface.OnClickListener { dialog, whichButton ->
isDeletedClicked = true
context?.apply {
// Remove the notification programmatically on button click
NotificationManagerCompat.from(this).cancel(notificationId)
}
})
dialog.setNegativeButton("Don't delete", null)
var dialogUI = dialog.create();
dialogUI.setOnShowListener {
val view = (it as AlertDialog).window
view?.setBackgroundDrawableResource(R.drawable.alert_dialog_layout)
// change positive button yes background
val positiveButton: Button = (it as AlertDialog).getButton(DialogInterface.BUTTON_POSITIVE)
positiveButton.background = context!!.resources.getDrawable(R.drawable.yes_alert_background)
positiveButton.setTextColor(context.resources.getColor(R.color.white))
val negativeButton = it.getButton(DialogInterface.BUTTON_NEGATIVE)
negativeButton.setTextColor(context.resources.getColor(R.color.dialog_no_text))
}
if (Build.VERSION.SDK_INT>26)
dialogUI.window!!.setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY);
else
dialogUI.window!!.setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
dialogUI.show()
} catch (ex: Exception) {
//Log.d(TAG, "$ex")
}
}
}
}
The dialog activity looks like follows from which I need to remove app label (Hello):
