My question is similar to "Android Studio" debugging - display variables as hexadecimal, but I want to know how to make this the default setting.
I know how to change the setting for individual values:
but for checking the values of all the characters in long strings, this becomes tedious. Unicode characters are much more readable when displayed in hex. Is there any way to set this as the default in Android Studio? I looked in File > Settings > Debugger but I didn't see anything.
Right click to get the context menu and choose "Custimize Data Views...".
Then check "Show hex values for primitives".
Now the values should automatically display in hexadecimal without having to manually change each one.

I am working on an MBCS app using MFC. I am trying to support Asian languages. For the purposes of this discussion, we'll say I'm trying to support Chinese. I am able to support Pop up dialogs via MessageBoxW and Dialog SCREENs by pasting Chinese characters directly into the RC file. I can't get file menus to work using either resource view or editing the RC file directly. Whenever I type in ANY Asian character, the screen shows ???. One ? for each character. I have tried modifying the menu in C++ using ModifyMenuW. I get more question marks. Visual Studio shows everything working, and the RC file is unicode (UTF-16). I can't easily convert my project to unicode mode. Spanish, French, and German all works fine (one of the Essets in German doesn't work, but that isn't a show stopper). What should I try next?
Thanks in advance!
Well, the easy answer would be change the application to Unicode, but this is not always simple, or possible at all.
Concerning using Unicode in a MBCS application, some things are possible and some others not. For example, I have made a MBCS application displaying and editing translations of program strings (messages, menues etc) in a ListView control, however ListView does have a specific message to turn it to Unicode (LVM_SETUNICODEFORMAT) and support operations (see also CCM_SETUNICODEFORMAT). Menus aren't controls though, but they do have "wide" (Unicode) functions.
If you want to use Unicode in your application, there are some tests you need to make. Success is not guaranteeded, but you can at least draw some conclusions and determine whether what you want to do is possible.
Test1:
You mentioned trying ModifyMenuW(), but this will try to modify an existing menu. Instead, try InsertMenuW() or InsertMenuItemW(). Any unicode string should be displayed properly, so try not just Chinese, but other laguages too (eg Greek or Russian). And btw, I can't see how French works and German doesn't (they use the same codepage - West European). What's the system codepage of your test-machine?
Test2: (if the above has failed)
Try changing the whole menu (SetMenu()) with having a single (unicode) menu item as its root.
Test3: (if the above have failed)
Then you need to check whether the window containing the menu must be Unicode. Create a simple "Hello World" Win32 application, or find a sample, if Visual Studio does not do this for you (these basically register the window class, create the main window and start the message-loop) - you must add a menu too, using the "wide" version of the menu functions explicitly. If this doesn't work, try changing the code that creates the window to unicode. This way you will know whether you need a unicode window, to own the menu.
Please make these tests and let us know the results. I will further post if needed.
I can see special characters ąęį when I do form design on static text label:
These character are changed while running:
If I set these characters in programming way I have:
How can I ensure that the correct characters are displayed instead of question marks as shown in the screenshot above?
UPD:
My project is Multi-Byte. I found that in another computer I can see special characters. Why?
You need to use Unicode character set for this to work correctly, and my guess is that you're using MBCS character set now.
You could change it in the project properties. Refer to this screenshot:
Visual studio editor is fully Unicode, meaning it could display such special characters as you type when you're designing the dialog. However, if your application is not built with Unicode support, it won't be able to display thsoe characters when it runs. Thich is why you see the ??? replacing the Unicode text when you run the application.
If you get different results on different computers this is obviously due to differences in system settings.
The setting that controls this is called "Language for non-Unicode programs", and can be found under Control Panel, Language, Change date, time or number formats. Unfortunately it's a global setting (ie cannot be set per application or programmatically) and requires a re-boot.
Consider making your application Unicode, if possible (and meaningful cost- or effort-wise).
I just started to use Android Studio and wondering if there is a way to search interactively in property window.
I mean like Xcode does. (It's not a properties, though.)
Is there a plugin or configuration for the function like this?
Android Studio actually has a search tool for properties similar to the one in Xcode. But it's implemented in a very unusual and un-intuitive way. Which makes it hard to find.
In Android Studio version 1.5.1, you have to click either on the 'Properties' header or any property-name below the header, and then you need to start typing the property you want, even though there is no text-box or any other indication that your typing will produce any effect.
When you do this, then a text-box appears with the characters you've typed in. And Android Studio highlights all the properties that contain your character sequence. You can then look only at the highlighted properties to find the one you want.
There is no filter like in Xcode, but if you start typing property name the selection will jump to the first match and the rest of the matches will be highlighted.
The Android Studio lint spell checker flags hex codes that look to it like words in certain files that would be better off unchecked, such as values/colors.xml and build/intermediates/dex-cache/cache.xml.
How do I tell lint to not spell check certain folders or files?
This can be done by using IDE scopes. In Android Studio (at least 3.4) you can configure each inspection per scope. The idea is that you create a scope that contains all files you don't want to be spellchecked, and then switch Spelling inspection off for this scope, but keep it on for everything else.
Add a new scope in Settings / Appearance & Behavior / Scopes that contains all files which you want to exclude from spell checking. For example, this pattern covers all svg files: file:*.svg. In your case it could be like file:*/colors.xml||file:*/cache.xml. IDE will highlight all affected files by green, so you can check if you entered correct pattern.
Then set up Spelling inspection, so that it is OFF for your new scope and ON everywhere else.
Had the same problem with colors.xml
I couldn't find a way to disable the check for a certain file, but I could get rid of the spellcheck on the hex codes.
Click Analyze->Inspect Code.
Choose Whole Project and click OK.
The inspection tool window will open with the results.
You should be able to see the problematic hex codes under Spelling->typo.
Right click any one of them and choose Exclude.
Did the trick for me. HTH
I'm facing problem with keeping proper order of XML attributes in Android Studio. As you can see below, the style attribute is between layout_* attributes, but I want it to be ordered by name (like in Eclipse). I'm using standard Intellij code formatter and the Android Studio gives users ability to set your own rules regarding XML ordering. The settings are located in Code Style -> XML -> Arrangement, but it seems not to work or I'm using it wrong. Any ideas how to order XML attributes by name using default code formatter?
<TestView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
style="#style/BackgroundLight"
android:layout_height="wrap_content">
</TestView>
Finally got it.
Choose File > Settings > Code Style > XML > Set from > Predefined Style > Android
Set File > Settings > Editor > Formatting > Show "Reformat Code" dialog
Run formatting on a XML file (CTRL+ALT+L by default)
You will see a popup window, set the Rearrange entries flag
Disable Reformat Code dialog in the settings
This way every XML file formatting will set the attributes in a proper order.
Edit:
Starting with Android Studio 0.2.6 release the XML Android style formatting is set by default, but you still have to set the Rearrange Entries flag manually.
http://tools.android.com/recent/androidstudio026released
Automatically apply the Android XML code style if a code style hasn't
already been customized. This will make it possible to automatically
order XML attributes (check the "Rearrange Entries" checkbox in the
"Code > Reformat Code..." dialog.)
UPDATE: the method I described below is an official way to fix this known issue, see: https://developer.android.com/studio/releases
After updating to the newest Android Studio v3.4.2 I found that it doesn't format XML code properly anymore. For instance, attributes ordering didn't work in layouts. It did indentation and namespaces ordering only.
I don't know the reason why it was broken after an update but was lucky to fix this:
Go to Settings (CMD + , ) on Mac.
Type format in Search box and click on Editor -> XML setting.
Click on the Android tab and make the same settings here as it's on a picture:
Settings on a picture quite normal, but of course you can tune this tab setting up to you.
Go to the Arrangement tab and you will see something like this:
The reason why attributes are not getting sorted - sorting rules are empty.
To fix this:
Choose Scheme and play with Default IDE and Project options. Switching between them may help.
Or choose Scheme which suites your needs and then click on Set from... blue text in right upper corner -> Predefined Style -> Android. You will see restored rules in the window:
I also chose Force rearrange - Always
To save result – click Apply.
Also you can click on a gear icon near Scheme and copy settings or even restore defaults.
P.S. To me standard rules are comfortable, but it can be customized further. Here is an article which may help doing this: https://medium.com/#VeraKern/formatting-xml-layout-files-for-android-47aec62722fc
Go to your layout XML
Try Ctrl + alt + shift + L then find checkbox label is Rearrange code and checked its.
To delete empty lines between them:
Preferences > Code Style > XML > Other > Keep blank lines: 0
And then just reformat your XML files.
There is a plugin for IntelliJ which might do what you're after...
