Update for Ubuntu As Rohit faced the problem in Ubuntu to format code shortcut, because the CTRL + ALT + L key is used to lock the screen in Ubuntu.

I found that Ubuntu which handle the key event first. So try to change the CTRL+ALT+L action in Ubuntu just to be sure.

Steps are :-

Go to System Tools -> System Settings -> Keyboard -> Shortcuts Tab -> System -> Lock Screen

Select the row New Accelerator... will be visible then press any Special key with Alpha key (like Shift + L). You changed the key shortcuts.

Now check format key in Studio.

You can also use eclipse sortcuts. Windows and Linux, go to File > Settings > Keymap , Mac OS X, go to > Preferences > Keymap and choose eclipse from the dropdown menu.

Netbeans:

I use NetBeans 7.1. Pressing Alt+Shift+F indents your selection. If nothing's selected, it indents the whole file.

In newer versions of NetBeans, you can even format multiple files/folders at a time! In the Projectswindow/sidebar, if you select one or more folders or files and press Alt+Shift+F. NetBeans asks"Recursively format selected files and folders?" and pressing OK will recursively format all the selected files/folders.

On Mac OS X, shortcut is Ctrl+Shift+F. (note: it's Ctrl and not ⌘)

 Eclipse:

Ctrl+Shift+F to invoke the Auto Formatter

Ctrl+I to indent the selected part (or all) of you code.

 Xcode:

Use Cmd+A first if you wish to format all text.

The keyboard shortcut is Ctrl+I
