Android studio code editor occur unreadable code unexpected
(1 answer)
Closed 2 years ago.
Suddenly Android studio displaying different characters for some symbols and Gibberish name in autocomplete. Is happening in both kotlin only and java only projects. when I select the autocompletion option it selected properly I mean it shows the correct method name in the editor, when I copy the symbol and paste it elsewhere it pastes as a normal character, also the app is successfully building and executing and the source code in notepad looks fine. How to fix it?

Answering my own questions after invalidating the cache and restarting many times, changing android studio font, editor font numerous times. finally, I was able to solve this problem you just need to change the color scheme font.
Thanx #MikeM. for referring the similar post.

I know that if you write something wrong in code you get a red underline.
My problem is that the whole word turns red and I get the error
"Cannot resolve symbol '(and then whatever the code is)'"
when I hold the mouse over it.
I have downloaded Java just to see if it were the problem. I also followed this tutorial on how to download Android studio.
The program I made is from this tutorial on Youtube.
The path text in the top gets a red underline.
I don't know if it helps but i'm using Windows 10 and Android Studio 3.3
Here you can see my code turning red:
You're writing Kotlin in a Java file. Because of this, your IDE doesn't understand the symbols you're using to define variables. Note that even more recent versions of Java don't support val, which is why I presume you're attempting to use Kotlin here.
Your choice: write your code in either Kotlin or Java, but not both at the same time.

Java 8u40 on OS X Yosemite
(1 answer)
Closed 7 years ago.
I'm unable to enter text into text boxes in windows/dialog boxes produced by Java. For example, I can't type text into Sun's "How to use text fields" example, (linked to from here). However, I am able to click buttons in Java's windows.
I'm running on a Mac with the latest version of OS X (Yosemite 10.10.2), and the Java System Preferences pane assures me that I'm using the "recommended" version of Java (Java 8 Update 40). I should add that I'm running stuff via Java Web Start here, which generates some security warnings.
I told Java to enable the Java Console but it seems only to be showing start-up boiler-plate.
EDIT: to be clear, I'm able to reproduce this issue even in code from the makers of Java, so I don't think the fix will be something as simple as add a line or two to my code.
If you know the name of textbox you can add text;
Let the name of your textbox is mytextbox
mytextbox.setText("The text what you want to write");
Perhaps you have to set the
textBox.setEditable(true)

How to tell Eclipse to show content assist automatically?
(2 answers)
Closed 8 years ago.
I recently downloaded and installed Eclipse Standard/ SDK, version: Kepler Service Release 2.
In the past, when using Eclipse, there has been an 'autocomplete' function available when typing, that would try to 'guess' what keywords and variable names you were typing- if it guessed the correct one, you just had to press 'tab' to get it to fill in automatically for you.
However, this autocomplete function doesn't seem to work with the current version of Eclipse that I'm using... and I can't seem to find a way to turn it on- I've tried Edit -> Word Completion, and Edit -> Content Assist, but neither of these options seem to make a difference.
Any suggestions?
Go to, Window >> Preferences >> Java >> Editor >> Content Assist >> Auto activation triggers for java, and enter .abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ , this will trigger the auto activation for class names, methods, etc...

i had logcat, console etc showing in java portion of the ADT, one day i closed it, then it was not showing in the java portion of the ADT, i tried to open it as window/show view/logcat,but nothing happens,same happens with the case of console also, but i was able to open it up in DDMS using the same way. why it is not showing in JAVA? is there any fix for my issue, please help
In my Eclipse, there are two LogCat views. One says "deprecated". Perhaps you're clicking on the deprecated one and it doesn't work at all on your box anymore?
