Code formatting shortcuts in Android Studio for Operation Systems

Question

I have started developing with Android Studio. In Eclipse I was using Ctrl + Shift + F, but in Android Studio it does not work. It will be different.

How can I jump to any method in a .java file? I was using Ctrl + O in Eclipse.

Is it available? What is the shortcut for code formatting?

Answer 1

Windows: Ctrl + Alt + L

Linux: Ctrl + Shift + Alt + L

macOS: Option + Command + L

Reference: Key Commands and here are all of the commands for Windows/ Linux users and for Mac users.

As Rohit faced a problem in Ubuntu with the format code shortcut, this is due to the Ctrl + Alt + L key being used to lock the screen in Ubuntu.

I found that Ubuntu handles this keyboard shortcut first. So you should bind the Ctrl + Alt + L keyboard shortcut to something else so that it doesn't conflict with Ubuntu.

Steps

1. Go to System Tools → System Settings → Keyboard → Shortcuts tab → System → Lock Screen.

2. Select the row New Accelerator..., then press any special key with the Alpha key (e.g. Shift + L). You should've successfully changed the keyboard shortcut.

3. Check if the keyboard shortcut now works in Android Studio.

Alternative method

Ctrl + Alt + Shift + L (to show a dialog)

You can also use Eclipse shortcuts.

• Windows and Linux: Go to menu File → Settings → Keymap
• macOS: Go to menu Preferences → Keymap and choose Eclipse from the drop-down menu.

Using MenuBar

• Select code which you want to reformat

• Click on Code in the menu bar and select Reformat Code as shown in the image below:

  

In Android studio 3.5, there is problem with rearranging the xml code, it also rearrange the views as well, so need to use these settings first.

Settings -> Editor -> Code Style -> XML-> Set From -> Predefined Style > Android.

Update for Android Studio 4+

Since Android Studio 4+, you might face issue shortcuts on mac. Shortcuts not working after updating to Android studio 4, in Mac? have an answer for that.

Answer 2

You can also use Eclipse's keyboard shortcuts: just go to menu Preferences → keymap and choose Eclipse from the dropdown menu.

The actual path is: menu File → Settings → Keymap (under IDE settings)

Answer 5

For formatting code in Android Studio on Linux you could instead use Ctrl + Alt + Super + L. You could use this and avoid having to change the system shortcut. (Super key is the Windows icon key besides the Alt key).

Answer 6

For code formatting in Android Studio:

Ctrl + Alt + L (Windows/Linux)

Option + Cmd + L (Mac)

The user can also use Eclipse's keyboard shortcuts: just go on menu Setting → Preferences → Keymap and choose Eclipse (or any one you like) from the dropdown menu.

Answer 10

For auto formatting your Java/XML files in Android Studio, use following commands:

As you are looking for a single point to go with your work as Eclipse did, there is no such built-in functionality in Android Studio, but it gives you the ability to do it through a macro. Follow these steps:

In Android Studio, open any of your source code files.

Press Ctrl + Alt + O This is used to find/optimize unused import.

If a dialog open select "Don't show it again" and hit Run.

Go to Edit > Macros > Start Macro Recording.

Press Ctrl + Alt + O.

Press Ctrl + Alt + L. This formats your code. (Shift+Ctrl+Alt+L for Ubuntu).

Press Ctrl + S. This saves your file;)

Go to Edit > Macros > Stop Macro Recording.

Save this created macro with a name, for instance: “Auto Formatting".

Boom, you have now successfully created your macro. Now just add/assign a shortcut to it:

Open Preferences.

Search in the left bar for Keymap.

In the right hand pane, click in the search bar and type the name of your saved macro ("Auto Formatting".)

Double click on your item. There might be two, it doesn’t matter which one you click on.

Click Add Keyboard Shortcut.

Set your keyboard shortcut to Ctrl + S.

Finally, confirm overriding Ctrl + S to be your new macro.

Answer 11

Ctrl+Alt+L might conflict with Lock Screen shortcut in Ubuntu. In such case you can change the keyboard shortcut for Reformatting Code as follows:

File-> Settings-> IDE Settings-> Keymap

Search for Reformat Code and change the keyboard shortcut.

Answer 12

Really, I went to this thread because of my Ubuntu locks screen after this shortcut Ctrl + Alt + L. So if you are have the same problem just go to the Settings - Keyboard - Shortcuts - System and change the default shortcut for the "Lock screen".

Answer 13

In addition to auto-formatting that the other answers describe, another trick is to highlight the text that you want to indent and then press

• Tab to increase the indent or
• Shift+Tab to decrease the indent.

How do I align/format code in Android Studio?

Answer 15

I think is clear that for code formatting in Android Studio the combination keys are:

CTRL + ALT + L (Win/ Linux)

OPTION + CMD + L (Mac)

However, we forgot to answer about the Jumping into the method. Well to go into any declaration/implementation there three ways:

1. Goto Declaration

CTRL + B or CTRL + CLICK (Win/ Linux)

CMD + B or CMD + CLICK (Mac)

2. Goto Implementation

These commands show a list of all the classes/interfaces that are implementing the selected class/interface. On variables, it has the same effect as Goto Declaration.

CTRL + ALT + B (Win/ Linux)

CMD + ALT + B (Mac)

3. Goto Type Declaration

These shortcuts will go into the declaration of the “AnyClass” class.

CTRL + SHIFT + B (Win/ Linux)

CTRL + SHIFT + B (Mac)

Additionally, there is a shortcut for Goto the Super Class. This will open the parent of the current symbol. Pretty much the opposite of Goto Implementation. For overridden methods, it will open its parent implementation.

CTRL + U (Win/ Linux)

CMD + U (Mac)

Answer 16

The shortcut that worked for me is

SHIFT+ALT+CMD+L

You can optimize imports to remove the ones you don't use, and auto import the new classes.

Answer 17

If you are using the Dart plugin, go to Android Studio, menu File -> Settings. And search for "reformat code with", click "Reformat code with dartfmt" under the main menu:

Click "Add keyboard Shortcut". Then press Ctrl + Alt + L and the shortcut should work (If Ctrl + Alt + L make the computer sleep/suspend, change the shortcut in your system settings to something else. Otherwise, both shortcuts will collide).

Answer 18

Try this.

• On Windows do Ctrl + Alt + L
• On Linux do Ctrl + Shift + Alt + L for dialog to open and then reformat.
• On Mac do CMD + Alt + L

Note: Here many answers for Linux is just Ctrl + Alt + L which is wrong. In Linux, doing Ctrl + Alt + L locks the system.

Answer 19

It's Ctrl + Alt + L for Windows. For a complete list of keyboard shortcuts please take a look at the user manual: https://developer.android.com/studio/intro/keyboard-shortcuts.html

Answer 20

Some times even I type Ctrl+Alt+L is not working in XML, so found this way to make it work.

Go to Settings --> Editor --> Code Style --> Select Default --> Ok.

For your reference see the screenshot:

Answer 21

I have had an experience using Ctrl + Alt + L in Windows that this shortcut did not work at all because it was reserved by another software, running at the background; which I realized later.

I decided to mention this issue as I thought it may be helpful . . .

The best key where you can find all commands in Eclipse is Ctrl + Shift + L.

One important is Ctrl + Shift + O to import and un-import useless imports.
