Same way to remove the comment block.

In spanish keyboard without changing anything I can make a comment with the keys:

cmd + -

OR

cmd + alt + -

This works because in english keyboard / is located at the same place than - on a spanish keyboard

Be sure you use the slash (/) on right side of keyboard.

For Line Comment:

Ctrl + /

For Block Comment:

Ctrl + Shift + /

You can see all keymap in Android Studio: Help ➤ Default Keymap Reference

Reviewing and Changing Keyboard Shortcuts in Android Studio

Keyboard shortcuts can be configured (and reviewed) via the Settings dialog, accessible via File -> Settings.

Once this dialog appears, to review (and/or add) a shortcut, do the following:

1. Select Keymap in the list on the left. Note that there is a "Keymaps" option, and depending on the original selection, shortcuts assigned to a given feature differ based on the Keymap.

2. Type "comment" or text corresponding to the feature for which the keyboard shortcut is to be reviewed/assigned. Each match has a line entry in the list below, and keyboard shortcuts are shown right-justified along with the feature. For example, both CTRL+ALT+SLASH and CTRL+K, CTRL+C are the two assignments for creating a line comment.

To modify a shortcut:

3. Select the resultant line corresponding to the feature for which the keyboard shortcut is to be reviewed/assigned
4. Right-click, and select the desired Add or Remove option.

回答6:

I use this sequence (not a 'linear' shortcut but useful anyway):

• alt+c then alt+b (holding alt) for block comment
• alt+c then alt+l (holding alt) for line comment

(they use the android studio menu)

回答7:

for German Layout (Deutsches Layout) the default is:

for line Comment: strg + Numpad(/)

for block Comment: strg+shift+Numpad(/)

回答8:

An Example for a Mac OS X 10.5+ with a German layout keyboard without NumPads:

1. Open Preferences
2. Search for "Keymap"
3. Expand "Main menu"
4. Expand "Code"
5. Delete all shortcuts (just a suggestion)
6. Add a shortcut for a single line comment (e.g. Ctrl++)
7. Add a shortcut for a block comment (e.g. Ctrl+alt +)

8. This way you can be sure that those keys are not mapped (except if you assigned them before to another function)

回答9:

On PC it's by default set to Ctrl + /. This will toggle commenting a selection or current line.

回答10:

In Android stdio CTRL + SHIFT + /

回答11:

Comment method like pro developers:

Windows/linux:

Line Comment : Ctrl + /

Block Comment : Ctrl + Shift

Method Commenting:

Type `/**` and press `Enter Key`

it will add the comment snippet like we see in standard documentation, give it a try this once.

/**
 * 
 * @param addOpacity
 */
public void setOpacityOnUserImage(boolean addOpacity) {
// Your business logic. 
}

回答12:

I am working with a german keyboard and the slash (/) is on the 7 key, meaning access would be Ctrl + Shift + 7. However, this does not work as this is predefined as something with bookmark 7.

I went to settings (search for keymap) and deleted all existing shortcuts. I than added Ctrl + 7, confirmed deletion of bookmark shortcut and now can work well.

Line Comment hold both: Cmd + É

Block Comment hold all three: Cmd + Alt + É

"É" is on the same position as "?/" in english one.

回答18:

Are you sure you are using / and not \ ? On Mac I have found by default:

• Cmd + /

Comments using // notation

• Cmd + Opt + /

Comments using /* */ notation

回答19:

If you are used with Eclipse, there is something in Settings>Keymap Keymaps: and you can pick Eclipse to keep the same shortcuts.

For Block Comment hold all three:

Ctrl + Shift + /

Same way to remove the comment block.

回答22:

In android studio you can do single comment with (go to line then Ctrl+/) and block comment with ( select text then Ctrl+Shift+/)

Also if you want to change color of commented text go to File->Settings->IDE settings->Editor->Color & fonts->Java->(Line comment or block comment) and change properties. I prefer it to be green which is used in notepad++ editor.
