Android Studio Collapse definitions and methods

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 + '+'

Here's screenshot for quick reference:

View -> Tool Windows -> Structure

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

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+.
