Counter Floating Action Button in Android with Example
Counter Floating Action button is seen in most of the E-commerce apps where we are using the functionality to display the number of items that are present in the user’s shopping cart. In this article, we will take a look at implementing this counter floating action button in our Android app in Android Studio.
What we are going to build in this article?
We will be building a simple application in which we will be simply displaying a Floating action button and we will be adding a counter to it. On clicking on that button we will be incrementing and decrementing the counter which is applied on that Floating action button. Below is the video in which we will get to see what we are going to build in this article.
