QUESTION
I have a ViewPager with a PagerAdapter that is called from another fragment, a main fragment if you will.
My PagerAdapter is showing the user images and the user can swipe between them using ViewPager.
I've registered an onClick listener for every image and it seems to work as expected, at least it returns the correct position if I debug the position from instantiateItem.
The problem is that this onClick is supposed to start a new fragment, like an overlay over the image that the user clicked on but it doesn't start the fragment over the current image that the user clicked on for some reason.
Example of what I mean:
On page one onClick it starts the fragment at the correct position, (overlaying the current visible view).
On page two onClick it starts the fragment on page 1 (not in the visible view and not where the onClick fired).
On page three onClick it starts the fragment on page 2 (not in the visible view and not where the onClick fired).
Code:
MainFragment.java
...ANSWER
Answered 2020-Jun-09 at 22:07I had a similar issue with FragmentStatePagerAdapter, and what worked had much to do with two of the adapter methods:
instantiateItem - "Create the page for the given position."
setPrimaryItem - "Called to inform the adapter of which item is currently considered to be the "primary", that is the one show to the user as the current page."
Because of the way the adapter works, where it instantiates the fragments before they are displayed, the instantiateItem method is called for fragments or slides that are not in view (apart from the first item). If you can override setPrimaryItem, and then leave the UI/view set up in instantiateItem, and then the rest of the logic (listener with the show/hide overlay) in setPrimaryItem, you can make sure the listener and the fragment are set to the currently active view/fragment.
Let me know if that makes sense to you
QUESTION
My code works fine up until I try to save my data, exit out, then reopen then load saved data. I save using localStorage.setItem('key', value) then I load using localStorage.getItem('key'), but after I load my vars are not holding the right values. Is localStorage.getItem('key') returning a string, because 1 +1 = 2, not 11 like it's displaying. please help.
The page itself is stored on my PC not online, I'm opening it up with Google Chrome. I run Windows Edge. When I try opening this with Internet Explorer, forget about localStorage.set/getItem all together. I've tried just running my code with the variables then try to save and load. (note:All my code works flawlessly until I try to save the variables, then reload them). I'm working on a video game so I need to be able to save my variables. And since I'm not sure where the problem in my code lies, I'm sorry but I see no other option than to post about 180 lines of code
...ANSWER
Answered 2019-Aug-11 at 21:02(This will restate a bit of what you hypothesized in your question for the sake of completeness)
If you look at the documentation for Storage.getItem()
, it says:
Return value
ADOMString
containing the value of the key. If the key does not exist, null is returned.
This means that no matter what data type you give in setItem
, the output of getItem
will always be a string. This is easy to test in the console:
QUESTION
I got a UserControl with a Click event that I want to be triggered by another Button's click event inside another UserControl. It doesn't work. UserControl2 is inside of UserControl1. I've been having this problem for a while, was using a RelayCommand class earlier with just MVVM in the rest of the app until the point when I had a scenario when I wanted to swap pictures on a button click. But the button and where the imageswapping happens shall be separated into two different UserControls. Anyway, I got the following XAML on Usercontrol 2 where the imageswapping is:
...ANSWER
Answered 2019-Mar-15 at 11:36A (regular) button click event is a routed event.
So long as it isn't marked as handled, the event will propogate up the visual tree and any subscribed handler will pick it up.
Your description is a bit confusing, because you mention an unspecified UserControl, Usercontrol 1 and 2. but I gather the user clicks in UC2 and that's "inside" UC1 and you want to handle the click event in UC1.
Do that by explicitly making e.handled = false; in any handler you subscribe in UC2.
The event should then "bubble up" and you can also handle it at UC1 level. NOTE this is not at some button in UC1, it's at UC1 level.
https://docs.microsoft.com/en-us/dotnet/framework/wpf/advanced/routed-events-overview
So you would wire up your handler in the UC1 tag, rather than a button in uc1.
Bear in mind you can template a button as any piece of UI you can define. So a Button can be templated as an image, usercontrol or whatever. Thus giving that whatever the behaviour of a button and click/command.
I do not follow why you can't just bind a command though. You could put the command in UC2's datacontext and use relativesource binding from UC1.
