Changing floating button image size programmatically

Question

I have floating button and image inside. And I need image to change size filling all space inside like here:|

I tried different scale types but it did\'t work.

Answer 1

When you set the maxImageSize in the XML, you are changing the normal behavior and icon size of the FAB.

The result of this code is : FAB with image size 56dp

Later to change it again but programatically, you can use ScaleType to change the icon dimensions. Here an example in Kotlin:

fab_main.scaleType = ImageView.ScaleType.CENTER_INSIDE

And then, here is the new result: FAB with smaller icon size

If you want to change FAB dimensions, may be using one of the following methods can help you: FAB methods

I hope this solution can help you.
