Implementing a Zoom in and Out on a ImageView

[Tala Osman]

I've looked around for libraries to use to zoom in and out of a image view but to no avail. Either they're too old and when I try to add the libaries to the grade files it complains. I might just find a way to code this functionality from scratch, but before I do that, does anyone else know of library?

Thanks for the reply. This is really useful but I am building my app with Java. If you have a link to a example with Java that would be great, and if not that is alright.

Not Android then? If that's the case I can move the thread from the Android forum to some other forum, but which one? Is it Swing? JavaFX? Something which I'm ignorant of?

I'm building my android app on Android Studio with Java.

You can freely mix Java and Kotlin in an Android App and in Android Studio. Android Studio even has an easy way to convert Java into Kotlin.

I'd recommend learning Kotlin, though, since that's the preferred language for Android these days. Someday I'll even learn Kotlin myself.

But a lot of Android help sites show both Kotlin and Java solutions. Check to make sure that there's not a link to a Java version of that page.
