In this tutorial, I am going to show how to create custom vertical dropdown icon menu in android programmatically. Creating and implementing custom menu is not so difficult in android because we can make such menu with XML and to make perfectly working we have to add little bit java code in our app activity file.

We can create and implement drop down icons menu in android only using one XML layout file and a java activity file. But to add some extra effect like animation, hover color, etc. we have to create some XML file in drawable folder or you can add some code in java activity file.

Here, you will learn not only to implement drop down custom icon menu in your android application but also learn to add onClick event to the icon and to add on press or focus color to the icon background.
