BubbleView | Bubble View | Theme library

I just know how to use Android Studio Code Yesterday. And I got a problem when I need to Change the text when clicking a button.

But when I text, Its don't work.

Here is my code:

I am trying to build an messaging interface and faced this issue. As this is messaging app, a message bubble either align leading or trailing. I thought doing this kind if thing, creating a subview called bubbleView which will align itself using a computed variable called bubbleViewCenterXConstraintValue.

This is the recyclerview item layout file:

Currently, I implement multiple corner radii on my bubbleView which is a UIView by doing something along the lines of:

I am trying to implement ironSource in my Android Studio Project but it gives me an error everytime.

So long story short - trying to implement whatsapp style reply to messages feature.

• User long taps (holds) on a chat bubble
• Chat bubble and cell background color changes indicating selection
• Present an action bar asking user if they want to reply to the message
• If user presses reply, restore the cell background color and chat bubble color to default

I am achieving this with a UILongTapGesture which I am adding to the whole collection view

Problem: The gesture recognises the tap point and the index path. The accurate index path is also printed when I use print(indexPath.item). The problem is I am unable to modify the properties of the cell that I access using this index path. I believe I am accessing the cell in the right way. I want to change the background color of the cell and the chat bubble once user taps on a cell but nothing happens

Here is the code:

I am making an app that gets data from sql and puts it in a recycle view i first tried it in a list view but i found it easier in a recycle view it is basically like a chat system app anyways,when i add my data into the recycle view it gives me this error in the logcat.

In onCreate() I have called this displayChatMessage() ListView not mentioning anything . But Firebase Database has data in it Data is not showing on emulator.
