XML : Resizing an image to keep everything on screen

Heelo, i am trying to make one central image scale properly to the rest of the screen that way it does not push the rest of the objects off the android screen.

Here is my code (formatting something like this is a big pain in StackOverflow)

And here is my XML for the selected class.

I am trying to resize the hangmanPhoto that way the scrollview at the bottom of the screen is not pushed off the screen if the user inputs a very long word.

ie: user inputs "This is a very long word" into the hiddenPhraseLabel2 or the clueLabel.

If you need more clarification, this is an android application i am making for school and it is supposed to be a user-determined "Custom Game" for the game of Hangman.

The user can set the word and a clue to pass off to their friend and if they input such a long word or clue, the horizontal scroll view (Which contains the letters A-Z) at the bottom of the application get's cut off by the boundaries of the screen.

This is, i think, a very complex problem. So if you can help me it would be greatly appreciated! Thank you for taking your time to help me!
