After I updated my android studio , the XML formatting is ruined in the layout editor. Initially each attribute was on a separate line. Now however two or three attributes take a line .
I went into Settings->Editor->CodeStyle->XML and under the Layout Files region I have Wrap Attributes set as Wrap Always and Insert Line Break After First attribute is checked.
Yet the effect doesn't appear .
Any pointers?
I had occurred. Coz u r using Project Scheme . To fix this go Preferences>>Code Style>>XML on Scheme Combo Box , change to Default IDE
For Me, I overwrite project to Project Scheme( one that u don't like) with Default IDE. select setting icon and Copy to Project.
After all finished, Close preference pane with OK ,And then u are good to go.
Good Luck!
Just go to File->Settings->Keymap and search Reformat Code. You can find your shortcut to format your code and also you can remove and add new shortcuts for this.

How can I enable the text/design Tab on the a src/main/res/layout folder on the activity_main.xml file that was created automatically during create new project? If i do right click and create xml file on the said folder, the design/text tab exist. Any suggestion? Thanks.
No Text/Design Tab on the Bottom Part of the Android Studio
Creating a new XML in the Res/Layout Folder, the design/text tab is now present.
Any help? this is super weird guys...
In Android Studio 3.6 use these three buttons (Code | Split | Design), on top right, to switch between views.
I had the same problem, restarting the IDE did make that tab appear again.
On Android Studio 3.6.1
Top Right corner under the main toolbar you have three different icons (Code, Split, Design).
View -> Tool windows -> Preview .
Output view:
use the three buttons (Code|Split|Design)on top right hand side to switch between views.
I also had this problem after upgrading to 1.5. None of the above suggestions worked for me. I noticed that the default relative layout xml has changed with a third xmlns line and an app behavior line. I opened an older project and copied the old relative layout header to replace the new. Instantly the preview function was restored.
You can also Move between Design / Text tabs in layout’s view with simple shortcut:
(Mac) : control + shift + ← / →
(Windows / Linux): alt + shift + ← / →
On the top right corner of the activity_main.xml file view, there are 3 icons representing "Code", "Split" and "Design". Click on the leftmost icon of the three ("Code") for the text tab.
In the android Studio window, at the left side there are two options available(Project and Resource Manager). Go to resource and there you will see an ADD Module option, click on that. After this you will see your text and design option will get enabled, you can go to your work area by Project Name->app ->src ->main->res ->layout.
Yes, Even I had the same problem. For the first time... I think It wont show, restarting the IDE did make that tab appear again.
I had this problem too, I deleted all the preference files, such as the AndroidStudioPreview folder & com.google.android.studio.plist, then restarted android studio, it worked.
You do not need to restart an IDE. All you need is to close an xml file that does not get a tab and reopen it within an editor. It is a little bug.
Navigate to activity_main.xml tab then Design and Text tab appears.
It doesn't appear in MainActivity.java tab.
You do not need to restart IDE.
If text/design tab is missing in new android studio, this can solve by two methods.
You have re-install android studio. And don't forget to delete android studio related all files from temp and local.
Or you can re-install SDK (software development kit) according to your device.
I am using Sublime 3 but I am a newbie. I was trying to define some preferences, like the font size. However, I messed up things and I am not being able to restore.
Currently, I have this two windows "dashboard":
How can I restore it to the default one-window view?
I tried to look for things over the preference menu, but checking/unchecking all the available options did not help me to solve this problem.
It looks like you added an extra column. Try going to View, then setting Layout to Single or use the keyboard shortcut: Shift+Alt+1.
If you used File/Split View, setting single column mode won't work. In this case I found you can just click on another tab and the split will go away. Not at all intuitive.
How can I set a maximum length for Android Studio's code editor, or may be set a word wrap?
In my Android Studio, no matter how long a statement I type on a single line, it never automatically goes to the next line, but rather a horizontal scroll bar appears.
When I autoformat using the Ctrl+Alt+L (reference), nothing happens.
My SO or Google search found a lot of material on this for Eclipse, but not for Android Studio.
If you need not a soft wrap,
but actually, brake one long line onto several lines you need:
Go to Preferences(mac) or Settings(windows) -> Editor -> Code style -> Java/Kotlin -> Wrapping and braces (tab) -> Check "Ensure that right margin is not exceeded"
Now try to reformat your code:
press
OPTION (ALT) + CMD + L on your Mac
(or CTRL + ALT + L on PC)
Edit 13.02.19
As noted in comments this option seems not available in settings for Kotlin.
However, there is a workaround to manually add it.
Here is what it takes to make it work:
Export the settings scheme.
Open saved xml file.
Find <codeStyleSettings language="kotlin"> tag (or create)
Add the WRAP_LONG_LINES setting manually:
<codeStyleSettings language="kotlin">
...
<option name="WRAP_LONG_LINES" value="true" />
</codeStyleSettings>
Save edits and and import back the scheme.
Here you go!
MacOS:
Click on Android Studio ( left top corner )
Click Preferences
Type Code Style in search
Click on Code Style
There is a filed right to the 'Hard wrap at' - you can enter needed about of symbols you need
In File | Settings, select "Editor", then "Code Style". There is an option "Wrap when typing reaches right margin".
Edit: Just tried it, and it doesn't seem to work. Anyway, maybe the option "Use soft wrap" in the "General" group is more what you want.
#Solace, actually #Fahim Faysal's answer is quite close to what you need, but since you want to solve the problem no matter how long a statement I type on a single line, it never automatically goes to the next line, 2 more steps you need to follow:
[Step 9] type the max length you prefer at `"Hard wrap at" ()
[Step 10] change "Wrap on typing" from Default: No or No to Yes
With version 4.1.2 and with Dart language you need to go to "File/Settings/Editor/Code Style/Dart" and modify the "Line length" to the preferred number.
In Android Studio:
File->Setting->
Editor->code Style->java->Wrapping and braces(tab:right side)->keep when reformatting->Line break(make unchecked)
You can change the max column width from:
File > Settings > Editor > Code Style > Right Margin (columns)
Android Studio 3.5:
Mac -
Android Studio > Preferences > Editor > CodeStyle > HardWrap at: ____
The existing answers already answer the question in straight forward way. As a different approach you could set the style guide to kotlin style guide code style. Then if you do alt + ctrl + l as you did, you'll see auto wrap as you expected.
Just open the settings, search for kotlin and look for kotlin under code style.
On the top right hand side of the settings window you'll see Set from..., click on it.
Then on predifined style > kotlin style guide
If you'd like to follow the kotlin formatting style this could reduce more effort. For more information: https://developer.android.com/kotlin/style-guide
My Environment：
Ubuntu 18.04
AndroidStudio 3.3.2
My operate：
File -> Settings -> Editor -> Code Style
Scheme -> select Project
Hard wrap at '120'
Apply
To move the grey vertical line, that tells Android Studio where to wrap your code, go to
Settings- Editor- Code Style- Java or Kotlin- Wrapping and Braces- Hard wrap at
and enter the number of characters, where the line should be.
For dart
settings => code style => Dart => Line length
In settings/code style/kotlin/wrapping and braces replace the "do not wrap" values with "wrap if long"
You can change the Hard wrap at param
Instead of choosing 'Restore default layout' I mistakenly choosed 'Store current as default layout', so my current layout (which I don't want to use) is set as default.
Now I cannot go to original layout anymore. Is there a way to reset the layout to its shipped value?
I'm on intellij 12.1.1, on Windows7.
Layout stores the position and state of the tool windows, you can change it back how you like it and store it as the new default.
There is no GUI to reset layout to the IDE default, but the configuration is stored inside the project directory in ./idea/workspace.xml file. When the project is closed you can delete <component name="ToolWindowManager"> node from this file.
To anyone who is struggling with this "basic" error, you can go to Settings (Ctrl + Alt + S) -> Appearance & Behavior -> Appearance -> Tool Windows and check the following check boxes:
Show tool window bars
Show tool window numbers (optional)
All the others solutions that I have found didn't solve the problem and it is very frustrating that the IDE does not give support to reset the Window to its default.
P.S.: I can't post a screenshot of the settings mentioned above due to security of my company laptop, but it is very easy to find following the path I have written.
Is there a way to change the color of a tab (in the tab bar) according to the path of the file?
I tried with the PythonScript plugin, but couldn't find a method to change the color of a tab.
I need this because I edit scripts from two environments at the same time, from a LIVE environment, and from a development environment, and I need to be extra careful when editing a LIVE file.
I was looking for a programmatic way to change the color of the tabs, and reviewed the online documentation of Notepad++ but did not find anything about it. So, instead, I propose the following method for your case, it could be helpful to always know which of your files are from the development environment and which from the live environment:
Open a blank instance of Notepad++:
Now start a macro recording: Press Start Recording button on Notepad++ toolbar:
Open a new document
Now you'll have two open blank tabs.
Right click newly open tab and click in option Move to other view from contextual menu
You'll have a window splitted vertically and your two tabs will be displayed next to each other. You'll use these two tabs as separated "containers" for your files
Press Stop Recording button:
Save your just recorded macro:
assign a keyboard shortcut:
Now you can run that recorded macro (from Macro menu, or invoking keyboard shortcut you assigned), every time you want to work on your two environments.
(Optional) Right click vertical separator between "containers" and click Rotate to right
Now your "containers" will be split horizontally and will be displayed one above the other. Personally, I'd recommend you this layout.
Click on the tab at first "container" and from there, open all your "dev" environment files; and analogously open all your "live" environment files from second "container". Note that currently selected container has a more intensely coloured active tab.
If you notice that your working space is small, drag the separator to increase your current "container" size, but I recommend you not to take it completely towards the end, because it will make difficult to differentiate which of the two "containers" you are working on.
Note: If you, mistakenly opened a file of an environment from the wrong "container" you'll always be able to fix that by dragging the tab and dropping it to the other "container":
So you'll always keep control of what files must be on each container.
That's it. I hope this info will be helpful for you.
About changing the color of the tab (not folder specific).
Notepad++ has a file called stylers.xml, located in the roaming folder or in the program folder. It also depends in the installation & windows version. If it does not exists then it is self generated.
At the very end of the file, it says
<WidgetStyle name="Inactive tabs" styleID="0" fgColor="xxxxx" bgColor="xxxxxx" />
And here it is possible to change the color of the inactive tab.
However, it does not work, it is a bug that has been "fixed" countless of times in the past. To the date, the current version 6.2.3 UNICODE, changing the values does nothing.
So far, editing the stylers.xml:
6.2.3 = does nothing
design guideline, gray + gray = not good.
6.2.0 = does nothing
6.1.8 = works.
Nice contrast
6.1 = works.
5.9.8 = works.
5.7 = edit works.
ps: sadly,it is not possible to change the fonts of the tabs.
Wanted to add this as a comment, the button's not there.
You can solve your actual problem by using multiple instances of notepad++, refer this. You can save different sessions and optionally use the "Open File In Solution (OFIS)" plug-in.
I've if you've picked a different Style like 'Black Board', then you will have to change these setting in it's .XML in '/themes', and these setting are found at the bottom of the file.
