I have this variable defined in a Kotlin file, but Android Studio doesn't suggest implementing methods, am I missing something :
private val mGestureListener = object : GestureDetector.SimpleOnGestureListener() {
}
SimpleOnGestureListener is a non-abstract class. Hence the IDE doesn't show the Implement methods options by default. The IDE shows this option only when there is at least one method that's not implemented in the class.
If you want to show the Override methods option, then place the cursor inside the braces and choose Code -> Override Methods... (Ctrl+O), or if you already know the methods that you want to override, just start typing the method name and it will show up in auto complete.
You can use Ctrl+O inside the object : Xxx block to open a dialog to see methods to override, and Ctrl+I to see methods to implement.
This is nearly the same as Henry's answer, but he uses mouse, I use keyboard.
Click or press enter on some methods to generate empty implementations, and type letters to do text-based search.
If you didn't find what you expected, you're probably overriding the wrong class/interface.
If you have abstract methods not overriden, you'll see red wave line under object. Alt+Enter will help you solve problem in such situation.

I'm repairing my friend's code and got confused.
My friend wants to fetch entered text (in EditText). Seems easy, right? Well, it is but instead of user input, he gets this warning/error:
To be honest I'm not sure how to fix it. He is coding in Kotlin (Android 10).
Activity that contains EditText:
And XML:
This is how it looks when debugging:
The app started working just fine after running "File -> invalidate Cashes/Restart" option, I just don't understand where this warning came from and how to fix it because the error remained unchanged (even though the app works). Do you have an idea how to solve it?
All the best!
fyi lambda expression like setOnClickListener from kotlin is not debuggable, see here.
if you want to debug variables inside setOnClickListener you should use the normal one e.g. setOnClickListener(object: View.OnClickListener {..})
sometimes there will be problem in auto generated binding files, if so it will be solved after invalidate cache and restart ide. sometimes the warning/error show but the project and complied without errors. so no need to worry about that. for next time post the code as code not screen shots.
I understand that the question is regarding evaluating expression, but there is a way you can read variables from your debugger console, even if you're inside an anonymous callback. I found it helpful sometimes. Here are the steps:
First enter debugger mode inside of your anonymous callback,
In your debugger console, look at the right side for "Frames"
Within Frames under , you'll see stack of function execution first top one on the list is the latest:
Click on row(s) below the latest function, until you find an instance of your activity AddInformationActivity. You will see the activity instance on the right side window under Variables. Don't go as far as selecting functions browned out, because those are from internal libraries.
When you see you AddInformationActivity instance, you can expand it and see its variables.
Hope that helps!
It's not a beautiful way, but if you create a method like this:
private fun debug() {
println()
}
and add a breakpoint on the println() it'll capture the activity.
(Don't use TODO as it'll crash the app with a NotImplementedError once called.)
I have this method now in my code all the time to call it whenever I need it.
I know, that question is old, but I just stumbled over it and needed a way.
I'm using UIAutomator test framework for long tests (concerning to my acceptance test). And I need to wait until some activity is started.
I decided to use By.clazz (android.support.test.uiautomator package) methods to find activity object. I expected that something like
uiDevice.wait(Until.findObject(By.clazz(SomeActivity.class)), 30000);
will work. But it doesn't. I suppose that object of my activity cannot be found. I tried to use other By.clazz methods with different params but without success.
So, my code is pretty simple:
UiDevice uiDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());
/*.... do something...
like click on buttons which will open some activities...
*/
//does not work, time value just for sample
uiDevice.wait(Until.findObject(By.clazz(SomeActivity.class)), 30000);
I found workaround solution with using By.res, like
uiDevice.wait(Until.findObject(By.res(BASIC_PACKAGE, "someMainIdInSomeFragment")), 30000);
But I have very complicated structure of the app with base activities and so on. I often have the same layout for different activities with load different fragments. So I need to know that we started exactly SomeActivity ,regardless of loaded fragments.
So, the questions are:
Is it possible to use By.clazz for Activity to find its object?
Is there some another way to find activity object with UIAutomator?
Did I do everything right? Or maybe there are some mistakes? Is it possÑ–ble to do with UiAutomator?
Thanks!
Using class with UiObject2
Find the EditText, make sure to click on it (legacySetText would do it implicitly), and set your text.
val input = By.clazz(EditText::class.java.canonicalName)
device.wait(Until.findObject(input), TIMEOUT).apply {
click()
text = "your_text"
}
Yes, could be done through the id.
// android:id="#+id/widget_id"
By.res(applicationId, "widget_id")
Your syntax seems good to me. Just make sure no spinner (or any other widget) is blocking your view during the click attempt.
So, what I'd like to achieve is:
I have a custom class which is basically a HttpRequest, I create the object with url, parameters, etc. And then I have to call execute() to execute it.
I was wondering, is there a way - by annotations, or whatever - to make Android Studio remind me to call this method?
I remember the was something similar with the android Toast, in the IDE a message like 'Did you forget to call show?' was shown if, in fact, I forgot to call show() after creating the Toast.
Thanks much to anyone who will help :)
You could try to create
Create a custom IntelliJ inspection
A custom LINT rule, if you want to check it on your build server and not on your local machine.
I have recently migrated to Android Studio and I am pretty used to the Source -> Override/Implement feature in Eclipse.
I was wondering where I could find the same feature on Android Studio. I've tried "Alt-Insert"/Generate-Override methods but I don't find the OnPause() method to override in the list. How do I get the methods that I want to override in the list?
These are the only methods that are available to me on my IDE.
Ctrl + O
should work well in Android Studio.
Press Alt(Left one)+insert.
It shows all the dialog with heading "Generate"
Choose override methods.
Shortcut- Ctrl+O
The method you want to override has to be declared in a class you implement or extend. It might be that your class does not extend Activity (for example). And your project might have to be an android project and not a plain java project.
My understanding is that you need to have the class in your code for Android Studio to offer you the override options pertaining to that class. The image you've posted seems to have only one class.
See how many I got:
My requirement is to put in a place name in a text field and show that in the map, so i used geocomplete js, which works well.
Now my user should be able to put in user defined places like 'my house', for that I need to remove the geocomplete on clicking a 'x' button on top of the map.
How can I implement this?
Thanks in advance
I wouldn't customize the package! When a new version comes out, you'll have to make the same changes you before.
Since you haven't provided any code, I can give you an idea of what I've done with JQuery validation method overrides.
You'll simply have to find the listener (something like $('#listenToThis').on('click', function(){ doThings(); }) in the geocomplete.js file, then override it in a file that is included after geocomplete.
If you're using bundles, just include your file after the geocomplete listener response is defined.
So, after you find those, you can do something similar to the following:
$.validator.methods.number = function (value, element) {
value = floatValue(value);
return this.optional(element) || /^-?(?:\d+|\d{1,3}(?:[\s\.,]\d{3})+)(?:[\.,]\d+)?$/.test(value);
}
The function above allowed me to validate client-side numbers that were formatted as currency in JQuery ($).
This overrides the JQuery.validator.methods.number function (a cheating way to override the function without changing the package code), so if you can pinpoint the geocomplete.addSomethingToMap or geocomplete.reactToClick function, you should override it and it will essentially work that way.
Warning, though: you will need to reinclude the changes when you want to reenable the feature. You'll have to override, override, override again. This may not be the best way if they're going to be adding hundreds of different new locations on one screen, but for up to a small unit, such as a dozen, it should be a good solution.
