How to generate javadoc comments in Android Studio

Can I use shortcut keys in Android studio to generate javadoc comments?

If not, what is the easiest way to generate javadoc comments?

I can't find any shortcut to generate javadoc comments. But if you type /** before the method declaration and press Enter, the javadoc comment block will be generated automatically.

Read this for more information.

To generatae comments type /** key before the method declaration and press Enter. It will generage javadoc comment.

Example:

/**
* @param a
* @param b
*/

public void add(int a, int b) {
    //code here
}

For more information check the link https://www.jetbrains.com/idea/features/javadoc.html

Here is an example of a JavaDoc comment from Oracle:

/**
 * Returns an Image object that can then be painted on the screen. 
 * The url argument must specify an absolute {@link URL}. The name
 * argument is a specifier that is relative to the url argument. 
 * <p>
 * This method always returns immediately, whether or not the 
 * image exists. When this applet attempts to draw the image on
 * the screen, the data will be loaded. The graphics primitives 
 * that draw the image will incrementally paint on the screen. 
 *
 * @param  url  an absolute URL giving the base location of the image
 * @param  name the location of the image, relative to the url argument
 * @return      the image at the specified URL
 * @see         Image
 */
 public Image getImage(URL url, String name) {
        try {
            return getImage(new URL(url, name));
        } catch (MalformedURLException e) {
            return null;
        }
 }

The basic format can be auto generated in either of the following ways:

• Position the cursor above the method and type /** + Enter

• Position the cursor on the method name and press Alt + Enter > click Add JavaDoc

You can install JavaDoc plugin from Settings->Plugin->Browse repositories.

get plugin documentation from the below link

JavaDoc plugin document

Javadoc comments can be automatically appended by using your IDE's autocomplete feature. Try typing /** and hitting Enter to generate a sample Javadoc comment.

 /**
 *
 * @param action          The action to execute.
 * @param args            The exec() arguments.
 * @param callbackContext The callback context used when calling back into JavaScript.
 * @return
 * @throws JSONException
 */

You can use eclipse style of JavaDoc comment generation through "Fix doc comment". Open "Preference" -> "Keymap" and assign "Fix doc comment" action to a key that you want.

Here we can some something like this. And instead of using any shortcut we can write "default" comments at class/ package /project level. And modify as per requirement

   *** Install JavaDoc Plugin ***



     1.Press shift twice and  Go to Plugins.
     2. search for JavaDocs plugin
     3. Install it. 
     4. Restart Android Studio.
     5. Now, rightclick on Java file/package and goto 
        JavaDocs >> create javadocs for all elements
        It will  generate all default comments.

Advantage is that, you can create comment block for all the methods at a time.

In Android Studio you don't need the plug in. On A Mac just open Android Studio -> click Android Studio in the top bar -> click Prefrences -> find File and Code Templates in the list -> select includes -> build it and will be persistent in all your project

• Another way to add java docs comment is press : Ctrl + Shift + A >> show a popup >> type : Add javadocs >> Enter .

• Ctrl + Shirt + A: Command look-up (autocomplete command name)

Simply select (i.e. click) the method name, then use the key combo Alt+Enter, select "Add JavaDoc"

This assumes that you have not already added comments above the method, else the "Add JavaDoc" option will not appear.

In Android studio we have few ways to auto-generated comments:

• Method I:

By typing /** and Then pressing Enter you can generate next comment line and it will auto-generate the params, etc. but when you need the hotkey for this check out method II on below.

• **Method II: **

1 - Goto topMenu

2 - File > Settings

3 - Select Keymap from settings

4 - On the top right search bar search for "Fix Doc"

5 - Select the "fix doc comment" from the results and double-click on it

6 - Select Add keyboard shortcut from the opened drop down after double-click

7 - Press the shortcut keys on the keyboard

8 - Goto your code and where you want to add some comment press the shortcut key

9 - Enjoy!

Add Javadoc

• /** + return
• set cursor inside method name -> ⌥ Option + return -> Add Javadoc

Just select the Eclipse version of the keycap in the Keymap settings. An Eclipse Keymap is included in Android Studio.

i recommendated Dokka for geneate javadoc with comment and more

I'm not sure I completely understand the question, but a list of keyboard short cuts can be found here - Hope this helps!

Android Studio -> Preferences -> Editor -> Intentions -> Java -> Declaration -> Enable "Add JavaDoc"

And, While selecting Methods to Implement (Ctrl/Cmd + i), on the left bottom, you should be seeing checkbox to enable Copy JavaDoc.

Because almost of us use Kotlin, you can generate JavaDoc (KDoc) using plugins. In Android Studio open Settings (press Ctrl+Alt+S), select Plugins and find kdoc. I downloaded KDoc-er, but you can choose any of them. Then restart Android Studio.

Find any class/method, type /**, press Enter. You will get a short description like:

/**
 * User data
 *
 * @property name
 * @property avatar
 * @property gender
 * @constructor Create empty User data
 */
class UserData(...

to generate javadoc comment use /** Your docs */

ALT+SHIFT+G will create the auto generated comments for your method (place the cursor at starting position of your method).
