I am having a method, handling the correct/incorrect answers entered in a quiz game:
public void answerButtonClickHandler(View v)
{
Answer answer = myAnswers.get(v.getId());
if (answer != null)
{
myQuestionsAnswered++;
if (answer.isCorrect())
{
myCorrectlyAnswered++;
v.setBackgroundResource(R.drawable.answer_button_correct);
}
else
{
v.setBackgroundResource(R.drawable.answer_button_incorrect);
}
}
What it is doing so far is to check if the answer is correct or not (this part works fine) and sets a corresponding template. What I'd want to add as functionality is when the wrong answer is marked, the correct one to be marked as well. I was trying to keep the state of the vies (v) in a new View variable, in both of the states, but have not done the trick so far. Thanks you!

I am developing an accessibility service for Android. The service calls an app, and that app has a RecyclerView. Then I want to click on an element of the RecyclerView with performAction(AccessibilityNodeInfo.ACTION_CLICK) but it is not working. I know there are a few similar questions but none of them works for me. Also I checked the official documentation for the class of the performAction method https://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo
This is my code:
#Override
public void onAccessibilityEvent(Accessibility event){
AccessibilityNodeInfo source = event.getSource();
if(source != null){
List<AccessibilityNodeInfo> list = source.findAccessibilityNOdeInfosByText("mystring");
list.get(0).performAction(AccessibilityNodeInfo.ACTION_CLICK);
}
}
This is my configuration xml file:
<accessibility-srvice xmlns...
android:accessibilityFeedbackType = "feedbackGeneric"
android:AccessibilityFlags = "flagDefault"
android:canPerformGestures = "true"
android:canRetrieveWIndowCOntent = "true"
I think I misunderstood something, but i don't know what can be. Any help is appreciated.
The simple answer is that while finding the node by text is fine, that particular node was not the node with the desired onClick event. The solution is to call
list.get(0).getParent().performAction(AccessibilityNodeInfo.ACTION_CLICK)
The clarifying discussion is below
I think .performAction(AccessibilityNodeInfo.ACTION_CLICK) is right, but there might be some other concerns. Sorry for posting as an answer but a comment is too small.
Are you sure the onAccessibilityEvent is being called? I don't think that is the right event, but I can't be sure. Maybe put a log in there to ensure it's calling the event when you expect it to be called.
Also, looking at the source might restrict your search, maybe instead of event.getSource() try using rootInActiveWindow (I use Kotlin so it might have a method, see https://developer.android.com/reference/android/accessibilityservice/AccessibilityService#getRootInActiveWindow(int))
EDIT: 28 March 2022
I have run this code on my own accessibility service and it does click the button. But it's very prone to overflow.
var ranOnce = false // prevent overflow
override fun onAccessibilityEvent(event: AccessibilityEvent?) {
if (event == null) return
if (event.eventType == TYPE_WINDOW_STATE_CHANGED) return
if (event.source != null && !ranOnce) {
val nodeList = rootInActiveWindow.findAccessibilityNodeInfosByText("Menu")
//event.source.findAccessibilityNodeInfosByText("Menu") // <-- always nothing in list
Log.d("onAccessibilityEvent", "List of nodes: $nodeList")
if (nodeList.size > 0) {
android.util.Log.d("onAccessibilityEvent", "Node info: ${nodeList[0]}")
ranOnce = true
nodeList[0].performAction(AccessibilityNodeInfo.ACTION_CLICK) //<-- caused an infinite loop!
} else {
Log.d("onAccessibilityEvent", "No nodes found")
}
} else {
Log.d("onAccessibilityEvent", "event.source is null!")
}
}
Here the Text Area is constantly changing in terms of number and I want to trigger an event when the Text Area gets a particular number example I have tried this -
public void myfunction45(Canvas Panel)
{
if (Indicator = 45) {
Panel.enabled = false;.
}
} //(indicator- www.progress).
But it does not work(it does not read it nothing happens). how do I match the condition as the number is to be specific. please give an example for explanation. Thanks in advance.
That if statement would cause you problems.
You would want:
if(Indicator == 5)
instead. At the moment you're assigning the value without checking it, this would cause a compiler error. If it's just a typo, then update your answer, slightly confusing otherwise.
With regards to checking the text value. You'd have to grab the text value, for that you need a reference to the Text area. This approach assumes that the text area has it's value set by a user. Currently you're not grabbing any text values to compare, as a result, the if statement won't know what to compare.
Here's one approach:
public void myfunction5(Canvas Panel)
{
float result;
string textValue = yourTextArea.text;
if(Single.TryParse(textValue, out result))
{
if(result == Indicator)
{
Panel.enabled = false;
}
}
}
You use TryParse to avoid any potential exceptions that would be thrown if the user entered something that wasn't a number. This method will take the value from your text area, how you get your text area is up to you, and try to parse the text value into a float. The method will return true if the parse was a success, false otherwise.
Here's the reference for the TryParse stuff:
https://msdn.microsoft.com/en-us/library/26sxas5t(v=vs.110).aspx
If you wanted to parse it to an int, then you'd be using the Int32's version of TryParse, https://msdn.microsoft.com/en-us/library/system.int32_methods(v=vs.110).aspx
I'd also recommend having a peak at the Input Field documentation: https://docs.unity3d.com/Manual/script-InputField.html
You can subscribe your method to the Input-fields On Value Changed event, your function will need to tweaked slightly though:
public void myfunction5(string text)
{
float result;
if(Single.TryParse(text, out result))
{
if(result == Indicator)
{
CachedPanel.enabled = false;
}
}
}
Don't forget to store a reference to the panel you want to disable.
Hopefully this is what you're after.
Panel is already a Canvas type, it doesn't make any sense to GetComponent<Canvas> on the same type.
Try using Panel.enabled = false;.
For the rest, we don't know how you get the Indicator reference, or how you built the UI hierarchy, so we can't assess if the problem is there.
Edit: I could I miss the single = baffles me lol. I should avoid answering questions when I'm tired.
I'm currently working on a school project in Android Studio and so far I've written a code which generates random equations.
Now I display two equations on the screen and the user then has to decide wether the second equation is bigger or smaller than the first one. If the second is bigger, the user presses the button 'bigger', if the second one is smaller, the user presses the button with 'smaller'.
Now I'm trying to write the code that if the user pressed correct, it generates a new equation, if he was wrong, the process stops.
I was thinking of if statements like so:
final ArrayList<String> arrayListCheck = new ArrayList<String>();
if(doubleAnswer1 > doubleAnswer2){
arrayListCheck.add("smaller");
} else {
arrayListCheck.add("bigger");
}
final Button buttonBigger = (Button)findViewById(R.id.button_bigger);
final Button buttonSmaller = (Button)findViewById(R.id.button_smaller);
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
if(v.equals(buttonBigger)){
arrayListCheck.add("bigger");
} else {
arrayListCheck.add("smaller");
}
}
};
buttonBigger.setOnClickListener(listener);
buttonSmaller.setOnClickListener(listener);
In the arraylist arrayListCheck it will store either 'bigger' or 'smaller'. Now I want to check if the elements in the arraylist are both the same (either both 'bigger' or 'smaller'), if so a new equation will be generated. If the elements in the arraylist are different (not both the same), the process will be stopped.
I don't know if that really works, so it would be nice if someone could help me with this.
If there is anything unclear in my question, feel free to ask and I will try to clarify the problem :)
Thank you already in advance for your help!
I wouldn't use an ArrayList for that.
I would do the following:
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
if(v.equals(buttonBigger) && doubleAnswer1 < doubleAnswer2) {
Log.v("TAG", "you are right");
} else if(v.equals(buttonSmaller) && doubleAnswer1 > doubleAnswer2) {
Log.v("TAG", "you are right");
} else {
Log.v("TAG", "you are wrong");
}
}
};
Arrays are not really neccessary for this kind of simple comparison.
My intent is to show the fragment if there is something to show and hide it if there isn't.
My problem is that, given the same coordinates:
On first attempt, mStreetView.getStreetViewPanorama().getLocation() has a non-null response and shows the view. However, the Fragment is black (blank).
On second attempt, mStreetView.getStreetViewPanorama().getLocation() has a null response and the view stays hidden.
My code:
mStreetView.getView().setVisibility(View.GONE);
mStreetView.getStreetViewPanorama().setPosition(customMarker.getPosition());
if (mStreetView.getStreetViewPanorama().getLocation() != null &&
mStreetView.getStreetViewPanorama().getLocation().links != null) {
mStreetView.getView().setVisibility(View.VISIBLE);
}
I'm not sure how to go about debugging this. It seems to me that the results shouldn't vary like this, especially since, even though it has non-null results, the results have (apparently) no valid value to allow something to be displayed.
Edit:
This coordinate functions as expected and shows the view properly populated: 33.6645598,-111.9253126
This coordinate shows the view, but it is black, then later returns null: 33.6492448,-111.9354228
These results are consistent.
Edit2:
I attempted to use the OnStreetViewPanoramaReadyCallback(), however the results were the same.
Code is now:
mStreetView.getView().setVisibility(View.GONE);
mStreetView.getStreetViewPanoramaAsync(new OnStreetViewPanoramaReadyCallback() {
#Override
public void onStreetViewPanoramaReady(StreetViewPanorama streetViewPanorama) {
streetViewPanorama.setPosition(customMarker.getPosition());
if (streetViewPanorama.getLocation() != null && streetViewPanorama.getLocation().links != null) {
mStreetView.getView().setVisibility(View.VISIBLE);
}
}
});
In one of my old projects found there is a race condition if you try to access the location too early
what I did was setup a handler and have a post delayed runnable fire after 1000 milliseconds then check the location. Doing this provided consistent results.
I dont know if this is still the current behavior but you can read what I did here
Android StreetView check if there is any view for given location
Edit
there appears to be a onStreetViewPanoramaReady callback now, are you using that?
If you use the 'getLocation()' before the view has been created, it will return null. It is recommended to wait until view has been created. Also, you have to create a callback to let you know when the streetview is ready.
getStreetViewPanoramaAsync(new OnStreetViewPanoramaReadyCallback(){
#Override
public void onStreetViewPanoramaReady(StreetViewPanorama streetViewPanorama) {
}
})
i am attempting to implement a built in controller that is part of the scoreloop library. the documentation states:
Basic Usage:
To invoke the TOS dialog if it was not accepted previously, the following code may be used:
final TermsOfServiceController controller = new TermsOfServiceController(new TermsOfServiceControllerObserver() {
#Override
public void termsOfServiceControllerDidFinish(final TermsOfServiceController controller, final Boolean accepted) {
if(accepted != null) {
// we have conclusive result.
if(accepted) {
// user did accept
}
else {
// user did reject
}
}
}
});
controller.query(activity);
but when i paste this into my code i get the following syntax errors:
am i using this incorrectly? how and where would this be used any ideas?
EDIT: after moving the statement to the method where i want to show the dialog i now get the following error:
You seem to be calling controller.query(activity) in a class body where a declaration is expected. Move the statement controller.query(activity) to a method where you would like to show the dialog.
