android-studio Android Studio Tips and Tricks Use Custom Code Styles, Share with other Team Members and Auto Format with Shortcut

Example

It's possible to have your own custom code styles, share them with other team members and use a shortcut to auto format the code in a file.

To create your own custom code style, go to: Preferences -> Editor -> Code Style

There are some general code style settings here. You can also select the language (Java for Android) and set the parameters as you see fit. There's a lot of settings.

Once you've done this, save your code style. This is just for safe keeping.

Once you've saved it, select "Copy to Project" from the "Manage" dialog. You will be asked whether you want to switch to this created scheme. Answer yes.

Once this is done, close the Code Style preferences dialog.

Now, verify that your code style settings have been saved in: .idea/codeStyleSettings.xml

Ensure that this file is not ignored in your version control system so that you can share it with your teammates.

Once your teammates have this file, they should also have the same settings.

Now, when editing a file, you can format the code by selecting:

Code -> Reformat Code

Shortcuts for Reformat Code (taken from this answer - see answer for details on resolving issues with shortcut in Ubuntu):

Win

Ctrl + Alt + L

Linux:

Ctrl + Shift + Alt + L

Mac:

Option + Command + L

When you perform a code reformat, a small dialog should popup informing you of the changes made. You can click "Show" in this dialog to bring up the "Reformat File Dialog".

You can also bring up this dialog from the Code menu and its corresponding shortcut.

Be warned that "Only VCS changed text" doesn't always work depending on how the code has been edited (it may ignore a rule if part of the code has not been edited).

You can also select text and show the reformat code dialog to format only the select text.
