Answer 1

If you're using Android Studio, you can show the line numbers by going to File > Settings > Editor > General > Appearance, then check the "Show line numbers" box.

UPDATE: Android Studio v1.5+

1) Click inside the editor, Command + Shift + A, and type "show line numbers"

2) Select the second option in Preferences and it will take you to the screen that used to exist in General > Appearance

3) Check the "Show Line Numbers" box
