I have an app that I want to do the following:
When the user clicks on a star imageView it updates the server (adds posts to my favoritePosts, and +1 to likesCounter), but it should also update the imageView (liked to unliked and vice versa), and the textView with the number of likes on the cardView I clicked.
Currently, the imageView changes, and it updates server correctly, but there are some things that do not work the way they should, such as:
Some titles disappear and reappear when I click the star imageView (to add posts to favorites), and the textView is almost never updated at all, and when it is, it sometimes decreases instead of increasing and vice versa. In my database it is updated correctly, like is added/removed correctly, likes counter is updated correctly, also when I exit and reenter the activity it is updated correctly.
I have tried this, this, this, this, this, etc, but none of these solutions worked for me.
