1. Convert ArrayList To String Array
2. Change Adapter Constructor From String [] to String List
3. Check if File Exist in Directory Path
4. Hide Keyboard By the Help of Any
5. Understaiding Migrating AndroidX
6. Send Constructor Parameter as new File name When File Just Created
7. Change Color of Specific Item In ListView And Adapter Specific Position
