If I use Xcode or visual studio all I have to do is hover my mouse (Or alt + hover) to get more information about what the variable is returning or expecting. How can I do the same thing in android studio?
Do I have something toggled off or does android studio not support something like that?

In Android Studio 2021.1. 1 Patch 1 the required list of options is located File > Settings > Editor > Inlay Hints > Kotlin .
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml. In the above code, we have taken text view to show global variable.
Android Studio configuration environment variables. The Android Studio configuration variables contain settings that customize the location of configuration files and the JDK. On start-up, Android Studio checks these variables for settings.
In Android Studio, highlight the method and either right click > Find usages or use the Alt + F7 shortcut.
It's ctrl + shift + p. You can customize it in File -> Settings -> Keymap -> View -> Expression Type.

One way I've found is simply placing the caret on the variable, and pressing F1. (Works with Flutter).
Alternatively, you can go to Settings->Editor->Code Editing and turn on Show quick documentation on mouse move.

In newer versions of android studio it is "Ctrl + Hover"
EDIT
On variable declaration line using "Ctrl + Hover" will show "Usages of variable".
On later usage of the variable it will show you its correct data type.
