Settings: Correctly align cursor in Settings

Steps to Reproduce:
- Click on Density Settings (DPI Settings) / Renaming BT Device / Renaming SIM Settings
- EditText Dialog pops up
- The cursor is at the leftmost side of the text
- Logically Cursor should be at rightmost side which can be aligned grabbing text length
