What language we can use to design a mobile app ?

Question

Hi, i'm a beginner.My question popped out when i was about to start learning Kotlin. Sources said that kotlin is a backend language. My question is :

If we are building a web, we use HTML as the structure and CSS as the design. But when we are making a mobile application (purely mobile), what language that we can use as the design of the app ?, and language for the structure and function of the app ? (Android)

Answer 1

Xml,native script,react native!

Answer 2

I used Android Studio like six months back,so correct me if l'm wrong. So then, I used some modified XML structure for front end. Backend java, json like that.

Answer 3

Ya, these days Android Studio has drag and drop option. So the elements you want like buttons are already pre coded. Just drag and drop, it will be displayed.

Answer 4

So XML can be used for the design thingy ?
