When I use IntelliJ idea and comment some portion of code, the comments are always close to code like below
But in Android Studio comments are far away from the code like below
How can I achieve comment settings like Intellij Idea in Android Studio ?
From the looks of it you are trying to comment the codes by selecting them all and using the comment option right. To achieve what you are looking for:
In Android Studio, go to File-->Settings-->Editor-->Code Style-->Java ...You can select the language you want, java as an example.. On the right You then have to select the 'Code Generation' tab, below a checkbox will show Line comment at first column untick that and your comments will be shown right next to the first indented line in your selection.
Comments generated will all be in one column based on the first line closest to the first column in your selection.
Check if this works for you.
On another you can always use block comment to easily comment a whole block /*....*/ or finally you can click anywhere you want and type // manually where you want it to be, a bit too tedious though. but works.
Try this out :
Android Studio > File > Setting > Editor > trailing in this uncheck the Always keep trailing spaces on caret line also use ctrl+alt+l to reformat the code.

IntelliJ IDEA has an inspection that checks for spelling. In the analysis overview, I can see how many spelling mistakes were found, e.g. 12 typos found. In the code they are highlighted using a wavy green line.
However, I find it very hard to look manually for those wavy lines. Is there a keyboard shortcut or a search function which will automatically skip to the next highlighted typo?
F2 and Shift + F2 shortcuts will navigate you to the Next / Previous highlighted error. You need to configure the error navigation first to Go to next problem instead of default Go to high priority problems option(from the context menu of editor right side bar):
See help for details. Another option is to use double click (F4 shortcut) from the Inspection Results window to go to the source.
IntelliJ IDEA 2016.3
If you want to fix all typos from the project, you can list all of them and iterate through them using double click (or F4 to open the source):
Analyze > Run Inspection by Name...
Type "Typo"
You will be able to see a list containing all typos grouped by file:
In Settings -> Editor -> Colors & Fonts -> General, you can add an 'Error stripe mark' color to Typo.
With the default settings of IntelliJ I find it difficult to spot the typos. So I do the following hack to spot and correct them once in a while.
Temporarily change inspection setting to show Typos as Errors.
IntelliJ then highlights the typos as Errors, making it much easier to spot them in the editor. I correct them and then revert the inspection setting changes. The changes can be kept permanently but I don't prefer that!
When editing Java files, if I'm at the end of the line and I type the Enter key, it starts the next line properly indented 4 columns, to match the line above. That's OK but it's indenting with a tab, not spaces, even though in File>Settings>Editor>Java>Tabs and Indents the checkbox for Use tab character is unchecked, and always has been.
If I just type the tab key I also get a tab, not spaces.
I never want to use tab characters; I always want to use spaces. I don't have this problem in Eclipse or Microsoft Visual Studio so it's not some system setting for my PC. Is there some other setting in Android Studio for this?
Edit: I tried the suggestion that Omar Al Halabi (below) made and it didn't work but while testing it I noticed something interesting: This tab problem seems to mainly apply to the beginning of the line, i.e., if I type Enter on the previous line, it immediately tabs over to the first indent position on the following line, using real tabs, not spaces. On the other hand if I'm typing some text on an existing line, once I've typed a little text, if I hit tab, it then tabs over using spaces.
hope this helps,
check Use Tab Character,
give all that values to zero than you not get space on enter in java code, like in below image,
one more thing is you have to change your code format settings or may need to disable it
This is not an answer, but I don't have enough reputation points to post my questions as a comment.
- Is this issue happening in all your Android Studio projects?
- Are you using the Default scheme for the general File->Settings->Editor->Code Style and also for the Java Code Style?
- Have you tried making a new Java Code Style scheme at the Project level for just one project as a test?
EDIT: This is a brute-force/shotgun approach.
Rename your \Users\<username>\.AndroidStudio2.1 directory (e.g., .AndroidStudio2.1_orig)
Open Android Studio and force it to use the default settings by choosing the "I do not have a previous version of Studio or I do not want to import my settings" option when the "Complete Installation" dialog window appears.
Run a recursive 'diff' between the new and old .AndroidStudio2.1 directories to find any changes you've made to the default settings so you can re-apply them. The settings are kept in XML files so they are human-readable. Keep an eye out for any differences that may affect Android Studio use of tabs & spaces, because those might be the source of the problem.
If this does not work, then you may have to re-install Android Studio.
Try opening Settings->Editor->Code Style->Java. Check "Use tab character". Click OK.
Then go to File->Invalidate Caches\Restart -> Invalidate and Restart.
Then, again, go to Settings->Editor->Code Style->Java. Now uncheck "Use tab character" and hit OK.
If it still doesn't work change tab size and indent and then restore them back if you want.
The IDE tries to position the lines as if they belong to the same block. Also very likely you had used the tabs on the previous line. You can try to deactivate Detect and use Existing file indents for editing
I'm writing code guidelines for some of our projects on Android. I'd actually like to facilitate this by using Android Studio code style preferences. I'm almost done setting parameters there: Android Studio->Preferences->Editor->Code Style->Java.
One thing I'm missing is that we want comments to be formatted like this :
// a useful comment
Instead of :
//a useful comment
How do I tell Android Studio to but a space between slashes and the text in the comment? Thanks!
If you press CTRL / or CMD / it will put // at the beginning of the line and the comment will be properly indented.
// comment with two indents
For this to work Comment at first column must be checked in Editor->CodeStyle->Java->Wrapping and Braces->Keep when reformatting like mentioned in another answer.
If you want to write multiline comment you can use CTRL SHIFT / or CMD SHIFT / That way when you go into new line, you will have one space after the comment start
/*
* there is space before this*/
I have just solved this problem.
I think you can find Code Style -> Java -> Code Generation
There is a Comment Code and select the Add a space at comment start
I think your problem can be solved.
You can do it under the tab Wrapping and Braces.
Whenever I'm just typing some code in Eclipse, and I click on the Error lightbulb on the gray ribbon area, my code just runs away from me, and I have to close the file and re-open it to see my code again. Can someone help me figure out how to STOP this? Thanks
I may have fixed this issue.
Going to the Eclipse settings, and to
Java > Editor
Uncheck the box "Only show the selected Java element."
This seems to fix the problem.
Please follow these steps (I am running eclipse on MAC) to fix XML problems. You later commented it was a java file but actually java files are okay with me.
Open Eclipse
Open menu eclipse->preference or file->preference (windows version I am guessing)
In the left pane expand the following nodes XML->XML Files->Editor
Please take a look # the following image and make sure yours has the same settings and hit apply.
The problem is gone but you cannot add blank lines in the XML files any more.
You could be accidentally invoking code folding.
Does your editor show you something like this?
The red arrow (added for emphasis) points to a minus sign in a circle. When you hover over the area underneath the minus sign, a vertical bar is drawn from the minus sign to the bottom of the code block, of which the minus sign is next to the top line.
If you (perhaps accidentally) single-click on the minus sign or double-click on the vertical bar, then the whole block of code collapses and only the first line is shown. The minus sign changes to a plus sign. Clicking on the plus sign expands your code again.
Under any condition you could just click on the java file under the name of class you created it appers like that
Src
Default package
"Name" .java
Sometimes my code moves on its own or just disappears in the Eclipse XML editor.
When I highlight the affected code, the highlighted lines try to correct themselves. But when I scroll or drag the mouse in the opposite direction the code shifts again. In essence I will have repeating, missing, and broken lines of code being displayed from an otherwise error free file. The files affected do compile and if I close / re-open them this problem goes away, for the moment. Any ideas on what's happening?
Addition:
Jeff Axelrod provided a link to a new bug report with Google.
This bug is (finally) fixed in ADT 21. The fix is now available in ADT 21 Preview 9, posted a few minutes ago, here: https://android-review.googlesource.com/#/c/44936/1
The reason you get weird visual artifacts is that if a file contains broken DOS line endings (multiple carriage returns without a newline for each carriage return), Eclipse gets very confused. That's Eclipse issue https://bugs.eclipse.org/bugs/show_bug.cgi?id=375421 .
There are two parts to the fix:
(1) First, ADT was fixed such that it no longer introduces these \r\r sequences into the document. This makes sure that you don't get new documents which triggers the weird editing behavior, but it does not retroactively fix older documents with these line endings, so if you open them, you still get weird editing behavior.
(2) Second, there's a new lint check which looks for broken line endings in documents. This runs incrementally, so if you edit an XML file which has this problem, ADT will add an error marker for this problem -- along with a quickfix to perform surgery on the document to fix it.
In short:
Get ADT 21 Preview 9; run Lint on your projects and look for any complaints about files containing broken line endings, and if it finds any, apply the quickfix. From now on, further edits with the layout editor should keep the files consistently formatted.
FYI, the relevant fix is here: https://android-review.googlesource.com/#/c/44936/

After some tests, I have found that the option "Automatically format the XML edited by the visual layout editor" (in Preferences | Android | Editors) might be the culprit here.
With my tests, I've found that changing a property (such as the layout_gravity) while in Graphical Layout design mode always screw up the visual display of the file when I go back to the XML (text) mode when this option is ON but that I have no problem when it's off.
If you want to format the XML upon your return from the Graphical Layout design mode, simply use the shortcut Ctrl+Shift+F. Also, I didn't see any problem with using the option "Format on Save"; even when I use it in the Graphical Layout mode; so you can use Ctrl+S instead while you're still in the Graphical Layout mode to both save and format your XML.
I've tried other editors options like "Show range indicator" or "Use characters to show changes in vertical ruler" but I didn't see any difference in behavior with activating or de-activating these options.
Finally, to correct the visual display of the file when it's corrupt; I found that using the shortcut: Ctrl+A, Ctrl+C, Ctrl+V is a little easier than closing/reopening the file. This is equivalent to making a Select All, Copy, Paste; effectively copying the whole XML file over itself.
Still experiencing this bug on Juno (Eclipse 4.2.0, ADT r20).
My fix:
Go to Window -> Preferences -> Android -> Editors.
I have both "Format XML using the standard Android XML..." and "Use Eclipse settings for indentation...." checked. This solved the problem for me.
EDIT:
contain faster method, so it was bring to top:
Ctrl+F -> fill like that:
"Find" "\r\r\n"
"Replace" "\r\n"
Switch "Regular expression" to ON
hit the "Replace all" button
Ctrl+A
deselect text.
be happy =)
Original was here:
Just don't hide that issue, if you may fix it. Some times even closing the XML file didn't help.
For fix it let's look at the reason of it. First of all Turn On "Show Whitespace Characters" (Window > Preferences > General > Editors > Text Editors > Show whitespace characters )
Then back to your XML-file.
In scaled image you may see the difference of "\n"-symbol colors;
then just put cursor to that symbol, which is more dark.
look, two lines was selected 0o... that's may be the reason!
so just delete it, and press "Enter" or "Return" button for add "\n" symbol.
Hope it help you.
also you may find the other symbol of endline:
Just delete it too, and your XML will have a great look!
P.S. sorry for hyperlinks, i'm newbie and on SO i can't upload image or more than 2 links. so hope you'll get the point without additional pictures ;)
P.P.S. Thx to guy who vote up, now i can provide this with images.
I had the same difficulty and finally found the solution: Right click in the editor, select Source/Cleanup Document.
I had the same issue. The following steps were the solution. Link suggest its worked for others.
Go to Preferences -> keys
Unbind copy, paste, and cut (hit "apply", then "ok")
repeat step 1
Restore unbound commands from step 2 (I didn't restore cut, but I'm sure you'd be fine)
Notice there are 2 bindings for each of the 3 commands
Unbind secondary function for both copy and paste (leave ctl+c/ctl+v [copy/paste] bound)
At this point you should only have 2 bindings set to perform copy/paste (i.e., ctl+c/ctl+v)
Hit apply -> OK
This solution was found here.
When this bug appears with new versions of ADT (which are mandatory for fixing and where bug should not appear often) just use Lint tool to fix it..
Find it in Lint warnings and click yellow bulb icon in upper right corner of that Lint warnings list..
Hope it will help somebody
