I use React-Native-Maps and my map marker pins that overlap each other spring apart gracefully when i click them, so can i pick the one wanted?
I've used This library for the web side.
There are libraries that do this but normally it is implemented by adjusting the zoom level. Is that a possible solution or do you need to move the pins apart at the current zoom level?
If you want to move them apart at the current zoom level they could push into other pins and make the issue worse. You might be better off doing a bounding box search around whatever pin gets the click event and opening a popup to make a selection from any results in the box.

Right now, React Native ListView supports loading more data only in one direction, towards the end. If I add data towards the beginning, then it'll jump the scroll position.
Also, the ListView calls onEndReached in only in one direction.
Is there any way to implement a bi-directional ListView so that I can load more items in either direction without jumping the scroll position?
This is useful in case like, say the user came from a notification to an old item. So it'll be ideal to take the user to that part. Then as the user can scroll in either direction, I'll need to load data in either direction, without affecting scroll position.
My quesiton is: i have a windows phone 8 app - it has a Map Control on a page that shows the user's position.
We want to allow the user to disable the map control so it looks greyed out and disbaled and doesnt update (to save bandwith etc)
What would be the best way of doing this?
I would simply draw a control with semitransparent background on top of the map. thus all touch events would be stuck in the control, but the map would be visible under it still.
Hello i am new to Mono for android. I am trying to make a Calculator, in a normal windows forms application.
I can Drag a button or textbox to any position I want but how does that work in Mono for android, I want the buttons next to each other not only downwards. If I place buttons under eachother that go out of the framework I dont want that either..
I am not English il hope you will understand.
please help.
Android "supports", but has deprecated and doesn't endorse, pixel-perfect layout. Unfortunately the Windows Forms-style of dragging and dropping controls onto a design surface at specific pixel locations requires pixel perfect layout, so you can see the mismatch here.
For a Calculator, what you would instead want to do use a Table Layout or some other "resizable" container, so that your Activity can support the variety of device sizes that Android covers.
Most games (if not all) do not use Lion's full screen feature. They make themselves full screen using an unofficial method. The problem is - no matter how high I set the level of a window (I'm currently using level 25 - making the window higher than the status bar and its icons) it won't appear over the game. I want to achieve an effect similar to Steam's full screen overlay in game. Is this possible?
Full-screen games typically aren't windows at all. Most such applications are using CoreGraphics to capture the display (see CGDisplayCapture), bypassing window compositing entirely. (So you can't display content on top of them.) Note that this is perfectly "official" -- it's just a different approach from full-screening a window.
Steam works by having the Steam launcher inject code into the application to display the status popup. It isn't a technique that can -- or should -- be used in more general cases.
In my app, I have a view that cycles through a number of images. Non-VoiceOver users are able to swipe over the view in order to move backward or forward in the list of images. I've used the UIAccessibilityContainer protocol to properly fill this with accessibility elements so that VoiceOver users are able to "hear" all the items in this set by going through them with the one-finger next/previous item gestures.
What I can't figure out is how to update the image in the UI based on these events. Now, I realize VoiceOver is geared towards blind users and it's probably not a huge deal if the UI doesn't update, but some VoiceOver users are only partly blind, and it's a point of performing the correct behavior regardless.
Is there a way to tell when the user has selected a different element in an accessibility container so that I can update the UI accordingly?
Could the UIAccessibilityFocus Protocol be what you're looking for? Specifically accessibilityElementDidBecomeFocused? I would guess each element in your container should get this called when VoiceOver moves focus to them.
