Fix my Wordsearch Android Game Code

I'm seeking a skilled developer proficient in Java and XML for Android game development. The goal is to help me develop a Word Search Game. I am a developer and already have a crossword game and would like to add WordSearch game inside it. I have built the foundation but until now still struggling to make it work. I use recyclerview (Grid) and listener, it can detect word already. The issue is wild dragging (user can change direction midway ontouch). See the image for clarity.

Ideal skills and experiences required are:

- Proficient in Java, XML & Android Studio
- Has experience with Android game development.
- Understanding of Word Search mechanics.

I don't need you to build it from scratch. Rather, i need you to fix and improve my code.
