Is there a way/shortcut/built-in feature that can align code for operands, like '=' signs?
For example, there is a XAlign for Xcode (https://github.com/qfish/XAlign), allowing the user to select code that needs to be aligned and use a shortcut to align it automatically.
There is a Fields Group feature in Android Studio which can "Align in columns", but it does not work for code that is already written.
Indent code in Android Studio:
Windows
Ctrl + Alt + L
Mac:
Option + Command + L
The alignment for variable declarations works for only those that are outside of functions. The alignment feature in menu Preference → Code Style → Wrapping and Braces → Fields Groups → "Align in Columns" does not work for those inside the brackets/braces.
Here is an issue ticket on the JetBrains website: https://youtrack.jetbrains.com/issue/IDEA-56947#
This feature is available, but not in the stable release yet. It is available from build: 140.1761
At the time of writing this answer my current build is "135.1653844, built on December 18, 2014" on Stable Release.
In Eclipse which comes with Android Studio Bundle, the shortcut key is as follows to initiate Auto Formatter:
Ctrl + alt + L
If you want to change this combination, go to menu Preferences → Keymap and set to custom.
Windows:
Ctrl+Alt+L
Linux:
Ctrl+Shift+Alt+L
macOS:
⌥ option+⌘ command+L
For Windows and Linux in Android Studio:
Ctrl + Alt + L
For Mac:
Option + Command + L
Ubuntu Linux: Ctrl-alt-L (suggested by other responses) is captured by the window manager and locks the screen. So you need to change it: file->settings->keymap->main menu->code->Reformat Code. I use a double tab since I don't want the tab to shift a selection right.
This formats the code as you've specified in your preferences. To handle your specific request (aligning equals statements) go to: (file->settings->editor->code style->(choose language)->Wrapping and braces->Group declarations->align variables in columns
These styles are language specific so this particular option might not exist in the language you chose, or may be named differently.

I m new at flutter, I m using android studio and I want to know is there is any shortcut to see all the property of any particular widget at the time android studio it self, without going to the documentation page.pls help, it really help to reduce the development time.
In my case it's ctrl + space. But I'm not using apple's mac mini keyboard.
So "In my case" ctrl + space is the most useful. Then you can click on some widget e.g Text and press ctrl + j to see documentation. You can also press cmd + p to see all properties in inline mode.
This feature is called Code Completion:
On my MacbookPro & Android Studio Smart Code Completion -> fn+^+space was working. However Basic key shortcut ^+space was shadowed by MacOs keyboard input settings. So disabling the select the previous input source solved this shadowing. Now both shortcuts are working.
In Mac it's (control + J), if not working go to preferences or settings, then head to keymap, and then there search for documentation. you will get the shortcut.
Also try ( command + p ), I think that would work for what you are trying to find.
If I use Xcode or visual studio all I have to do is hover my mouse (Or alt + hover) to get more information about what the variable is returning or expecting. How can I do the same thing in android studio?
Do I have something toggled off or does android studio not support something like that?
It's ctrl + shift + p. You can customize it in File -> Settings -> Keymap -> View -> Expression Type.
One way I've found is simply placing the caret on the variable, and pressing F1. (Works with Flutter).
Alternatively, you can go to Settings->Editor->Code Editing and turn on Show quick documentation on mouse move.
In newer versions of android studio it is "Ctrl + Hover"
EDIT
On variable declaration line using "Ctrl + Hover" will show "Usages of variable".
On later usage of the variable it will show you its correct data type.
With Eclipse I would just hover over class or method name and CTRL+? to jump to the implementation. Even if it was an import I was interested in I could jump to the implementation.
In Android Studio, how is this done for methods and classes?
I don't think CTRL+Alt+7 is what I want. I want to go to where the code is written for the type or method defined that the cursor is hovering over or selected.
I've got lots of code to review so I would appreciate an answer for this.
I'm on a PC but I would like to know for Mac as well.
To jump to the implementation - Go with CTRL + YourMethodname OR Scroll-click on method as in Eclipes
Following are used in Android Studio
Add unimplemented methods: CTRL + I
Override methods: CTRL + O
Format code: CTRL + ALT + L
Show project: ALT + 1
Show logcat: ALT + 6
Build: CTRL + F9
Build and Run: CTRL + F10
Expand all: CTRL + SHIFT + NumPad -
Find and replace: CTRL + R
Find: CTRL + F
You can change shortcuts by following below :-
This section lists Android Studio keyboard shortcuts for the
default keymap. To change the default keymap on Windows and Linux, go
to File > Settings > Keymap. If you're using Mac OS X, update your
keymap to use the Mac OS X 10.5+ version keymaps under Android Studio
Preferences > Keymap.
Here is Official documentation for Android studio tips and shortcuts
For Mac: Android Studio Shortcuts for Mac OS
CTRL+Click (=left mouse key) should work, just as in Eclipse!
...to jump to the implementation...
In Android Studio, how is this done for methods and classes?
The keyboard shortcut you are looking for is:
CTRL + B
It could also be done by using the mouse:
Wheel/Middle Click on method / classes
Or by using both the mouse and the keyboard:
CTRL + Left Click on method / classes
On mac you can use this shortkey:
And if you are comforable to eclipse,you can change your keymap to exlipse in here:
I know this is old question but I found the solution for myself.
It is CTRL+ F12 for Method search and its name is File Structure(Main menu -> Navigate -> File Structure) keymap.
For Class search you can use CTRL + N. Its name is Go to Class(Main menu -> Navigate -> Go to Class) in keymap.
You can change their defaults in given paths in Setting -> Keymap.
I am using Flutter for app development.
But I am also using native Android (Kotlin) with flutter for the app development.
So in Android studio, jumping into classes written in Kotlin was not working if I opened the whole flutter project.
So solution is to open only android folder in the Android studio, instead of whole project where flutter files (lib folder) is also present.
Then I was able to use cmd + mouse (or ctrl + mouse for Windows) to jump into the Kotlin classes.
I want to format code in a freshly created Android application.
I messed up the code in this manner:
private static final
int AUTO_HIDE_DELAY_MILLIS
= 3000;
I want to format it with Ctrl + Alt + L, but it is not repairing the code. I use Windows 8.1.
Just right-click on the project or directory, and select Reformat Code
If you want to:
Order/FormatCode: Ctrl + Alt + L
Implement Methods: Ctrl + I
Override Methods: Ctrl + O
There isn't any need for them to be capital letters. This is just for the example.
First you will need to configure how your code is formatted. This can be done by going to
[Main Menu] -> File -> Settings
then go to
(Project Settings) -> Code Style -> Java
In this area you can define all the formatting rules that you would like to apply to your code.
Now you should check (or change) the keyboard shortcut for reformatting code by going to
[Main Menu] -> File -> Settings
then go to
(IDE Settings) -> Keymap
Just type Reformat Code into the search box at the top right to find it.
Once this is done, highlight the code you want to reformat and use the keyboard shortcut to reformat your code based on the rules you defined.
In Android Studio (on the Mac), I select the code chunk, and then select the Code menu item and click Auto-Indent Lines.
See screenshot:
Shortcut key (on Mac) is Ctrl + Alt + I.
At least on my Android Studio version, "keep when formatting - line breaks" was enabled by default. So you need to go to
Preferences → Editor → Code Style → Java and disable that checkbox (see the below screenshot).
Alt + Ctrl + Shift + L is the shortcut key for arranging the code in Ubuntu (Android Studio).
I am new to Android studio, it seems to be great IDE. But I have found that it has really strange key and shortcut mapping. I am using Czech keyboard.
When I try to type ">" by pressing Right ALT + . the symbol is not appearing, and I got message box that says "Go to custom Region. There are no custom foldings regions in the current file."
It is really strange behaviour, I have problem with writing many more characters like brackets,..... I tried to set keymap profiles to Visual Studio and more. But nothing seems to work. I didn't have any of these problems in any other IDE (Netbeans, Eclipse, Visual Studio, Xamarin)
Add this line:
actionSystem.force.alt.gr=true
to this file:
...\Android\android-studio\bin\idea.properties
As written here:
http://youtrack.jetbrains.com/issue/IDEA-91975
Yes, well... its problem with "old" keyboards. Newer keyboards don't have Alt Gr keys and IDE doesn't count on this in default.
Solutions:
Buy a new keyboard with no Alt Gr on it (using right Alt instead of Alt Gr is working for me)
Go to File -> Settings -> Keymap and search for implementation - delete Ctrl + Alt + B, hit "Apply" and you can now use this shortcut for "{"
As already mentioned below... add following line to ..\<Android Studio folder>\bin\idea.properties:
actionSystem.force.alt.gr=true
(update) Since newer version of AS (not sure which one, should be 2.3.3+), you don't need to manually access the properties file. Go to Help -> Edit Custom Properties and add actionSystem.force.alt.gr=true there.
Go to Preferences -> Keymap and choose Mac OS X as Keymaps.
I have been a long time Visual Studio user, so wanted to leverage all the keyboard shortcuts that I had picked up using Visual Studio.
On Android Studio, I first changed the Keymap to be Visual Studio. You can do this by using Alt+F7 on Windows and then search for Keymap.
By using the Visual Studio Keymap in Android studio, I got only debug related mapping, which was still a minority of what I use in Visual Studio.
So went ahead and added/modified some more mappings.
Here is the github link
https://github.com/vinayakg/VisualStudioKeymapforAndroidStudio/blob/master/settings.jar.
PR's welcome.
As for '>' sign (AltGr + .) and Android Studio 1.0.1, go to File>Settings, choose Keymap in IDE Settings section, search for "GotoCustomRegion" item (it is located in MainMenu-Navigate) and remove its mapping (via context menu).
If you're using macOS newest versions and have had weird behavior with the shortcuts, try this:
Go to Android Studio -> Preferences -> Keymap
Now change from "Mac OS X" to "Mac OS X 10.5+" and hit apply.
