Keep Controls Visible When Virtual Keyboard Pops Up In Delphi 10.2 Tokyo On Android And IOS

One thing that can really add polish to your application is setting it up so that when an edit field receives focus it automatically appears above the keyboard on mobile devices. If this is not done the keyboard can sometimes cover the edit field so you are unable to see what you are typing. There are a number of different ways to do this in Delphi 10.2 Tokyo (and previous versions).¬† We’ve written about this before can you can check out those posts here and here. There is also an example from Embarcadero called FMX.ScrollableForm on how to do this. The ScrollableForm example works well and I have used it in the past. However, in Delphi 10.2 Tokyo and Delphi 10.2.1 Tokyo it does not work quite right on Android. Developer Dave Nottage has come up with a solution to this problem and provided some source code to fix it. First you need his free library from GitHub called¬†Kastri Free. Next he posted some code to use with the library to make it all happen. Here is the code snippet:

The full source code is available in a forum thread on the Embarcadero Forums site. You can head over there and see the full thread. The source code is mainly for Android but probably also works on IOS. I would assume it is not meant for Windows, OSX, or Linux. The Kastri Free library also has a lot of other functionality you can check out as well.
