Android Studio Collapse definitions and methods

Editor Problem Overview

How can I collapse all definitions and methods within the Android Studio editor?

Visual Studio has that option on Edit-->Outlining, but I cannot find a similar feature in Android Studio. I am sure that this feature exists.

How can I access Android Studio's outlining feature?

It is called Folding in Android Studio.

First make sure it is enabled in config (it should be by default). Go to File -> Settings, then under the IDE Settings area find Editor -> General -> Code Folding, check the Show code folding outline.

To collapse/expand items use the Code -> Folding menu.

Edit:
To customize the keyboard shortcuts for these open Settings (File -> Settings) then select Keymap under IDE Settings. Now type folding into the search box (top right). Setup the keyboard shortcut for the various folding actions :)

For Windows:

  Minimize: CTRL + SHFT + '-'
  Expand:   CTRL + SHFT + '+'

For Mac:

  Minimize: COMM + SHFT + '-'
  Expand:   COMM + SHFT + '+'

View -> Tool Windows -> Structure

It's the equivalent to outline in eclipse. It gives you a far better overview of the class than folding.

my macbookpro

shift + cmd + ¡ (character or button before delete) Expand All

shift + cmd + ' (character or button after zero) Collapse All

windows

ctrl + shift + + Expand All

ctrl + shift + - Collapse All

If you want turn off all collapsing you need uncheck all fields in the Settings > Editor > General > Code Folding

Also you can use hot keys

ctrl + shift + + — expand code blocks

ctrl + shift + - — collapse code blocks

Solution 7 - Editor

Windows:
Collapse: ctrl + shift + Numpad-
Expand: ctrl + shift + Numpad+

Solution 8 - Editor

This is valid for windows users:

Select a bunch of code, then press ctrl+.. This folds your block
Then to remove the folding, move to the first line where the fold starts. Don't select the code, just click in that first line, and again press ctrl+.

Here are some helpful shortcuts for folding stuff.

Select Some Code And Press Ctrl + Alt + T to auto Insert Region folding around the code
To Collapse Specific lines of Code, Select the code and Press Ctrl + .(dot/full stop) & Same for the reverse i.e. expand again
To collapse All method bodies/ if conditions etc etc Press Ctrl + Shift + -(hyphen)
To Expand All Press Ctrl + Shift + +(plus)

Solution 12 - Editor

(for windows)

If you are talking about editor fold just like fcom + tab in netbeans

ctrl + alt+ t and then add desired text in the desc block

Solution 13 - Editor

>New Android Studio come up with a lot of new functions. These are the commands you can use to fold different type of code.

Solution 14 - Editor

I had this issue too. I figured out to click gear button where right top of project menu section. Then I unselected Show members option.

Solution 15 - Editor

What if i want to save that folding for future and adjust whenever i re-open that file?

Step 1: We use custom folding

Specify custom folding with comment //region for start and //endregion for end

//region anything that you want to write (you can even leave it blank)
...
//endregion

Step 2:

Go to Settings >> Editor >> General >> Code Folding >> Untick everything >> 'Tick Custom Folding Regions' & 'Tick Show Code Folding Outline' >> Apply >> Ok

Step 3:

Restart Android Studio. You will see that the demarcated region has been collapsed.

Optionally to collapse single method inside class rather than all methods @once use cmd and - on Mac Cheers

Solution 17 - Editor

For Mac you can use cmd + shift + -(hyphen/minus) to fold and to unfold every thing use cmd + shift + +
