What I want to do is check first if The referral code inserted by the user exist. But the problem is, it is always going on the addOnSuccessListener even though I had entered text which are not included in the database.

//Dont mind the next paragraph. I just need to add some more descriptions to save the edit//

I have an app where user can post item displayed in RecyclerView where Cloud FireStore is the backend. Now in first launch of the app it will load first 5 items. If RecyclerView cannot scroll vertically anymore it will fetch another 5 items. Everything is working except when I delete one item, other item gets duplicate.

First Problem Scenario:

In first launch it will load 5 items, so my list only have 5 items at this moment. Since my pagination limit is 5 when I delete one item from that 5 items, the query listeners tries to load the 6th item. In that part when I scroll up to load the next 5 items I'll get duplicate 6th item.

Like this 1, 2, 3, 4, 5 then the 3rd item will be deleted 1, 2, 4, 5 should be the result Unfortunately this is what I get 1, 2, 4, 5, 6. Its good to see that the query itself tries to load another 1 item after 1 item is deleted but after scrolling up the RecyclerView it will load another 5 items. Then this is what I get

I'm using Android Studio v3.1.2. I have a pair of activities with a ListView and a button. The button should alignParentBottom no matter how many items are in the ListView.

On my MainActivity, the ListView and Button render perfectly on a RelativeLayout. I can add lots of items to the ListView and the button stays put.

My JournalTabFragment, on the other hand, is a Fragment using a RelativeLayout in a TabLayout. The Fragment is created in code by the PetDetailTabbedActivity. The Fragment's layout is a modified version of the MainActivity layout, but the button doesn't show up, even when the ListView contains no data. I've tried using a LinearLayout with weights with limited success -- the button appears, but it floats below the listview content and moves down as data is added to the ListView. Then it gets scrunched vertically when there are several rows in the ListView.

Here's the most recent layout I've tried:

I have writed one action bar.It's too simple. When I click someone, they go to the same activity. There are only different between on the intent messages. I did as I always do. My problem is, when I click on first item gives me an exception but second one is purely working. What I did wrong? How can I fix it?

My purpose is : I want to send a message this activity at my action bar"s items. İf message 123 I am going to do anything but if other item has clicked I do different thing.I just want to find which item is clicked by users.
