You can create the onclicklistener() function in various ways by adding a click functionality to the Drawable EditText icon.
For example, if you click on the “add” icon, it will add value to the one displayed by the EditText . And if you click on the “remove” icon, it will reduce its value.
activity_main.xml
In the layout, create an EditText by adding icons to the ” drawableStart ” and ” drawableEnd .
