I'm building an app with Android Studio, and one of my activities (which lets the user draw on a canvas) has a 'toolbar', with things like 'Clear', 'Undo', 'Redo' etc.
I'm using the built-in icons for this - ie I go to the 'Drawables' folder, right-click, go to 'Add vector asset' and then select the appropriate icon. I've figured out that I can change the size of the icon that gets added, but I can't figure out how to use that.
So, on a phone screen, I'd like to use the standard 24dp icons. However, on a tablet screen, I'd like the icon to be bigger, as they're a bit lost on the bigger screen.
I can't figure out how to do this, though, and I'm not even sure whether I'm using the right approach. I know I can create different drawables sub-folders for different densities, but it's not so much the density that matters as the actual screen size.
How can I achieve this?
Go to the XML side of the designer. Find the image you are trying to increase the size of. Set the constraints according to the size you want and then include:
android:scaleType="fitCenter"
There are other values available, but this will increase the size of the image to the maximum possible without cropping while keeping it centered in the view.
