问题 There are 'TextSize' and 'High contrast' settings in 'ease of access' settings category on Windows Phone. Is there a way to ignore them or make an app to follow my own accessibility styles? 回答1: It's a common bug in apps that they ignore the high contrast settings and hardcode their own colours. So yes: you can do this by doing the wrong thing and hardcoding your settings instead of using the system resources. You can override most system brushes in your app resources in app.xaml and you can

问题 I'm building a windows phone 8.1 app that reads a file ( which holds GPS points, each point consists of e.g. latitude and longitude fields). For each point I have it so it's displayed with a little pushpin icon on the map control, based on its coordinated from the above file. Is there any way I can implement a click event on the push pin element and use it to e.g. to display another window where user can change/display specific point/pushpin info ( latitude or longitude) ? This is what I use

问题 My Windows Phone 8.1 App (C#/XAML) is ready for beta/store, but I have a strange problem. When my app is downloaded from the store on my Nokia 930, it quits instantly in a flash during splash screen of the app startup. The same app works fine on other phones (nokia 920,930,830,630) after downloading it from the store. My Nokia is registered as a developer device and used during development. The app works fine when side loading it from Visual Studio 2013.4 via USB and/or side loading the store

问题 I have a question regarding of changing button color in WP 8.1 on touch down or tap. I've already figured out how to change the background when there is no interaction, but I want to also change the background color of the button if it is tapped to transparent. Is this possible? 回答1: You'll have to modify the control template, as the "Pressed" state background is hard-coded into the control as "PhoneForegroundBrush": <VisualState x:Name="Pressed"> <Storyboard> <ObjectAnimationUsingKeyFrames

问题 Windows Phone 8.1 App , C# I would like to let the user add Pushpins ( which apparently are called MapIcons ) to the map and when the user clicks the newly created Pushpin some other ui-elements should appear. But apparently MapIcons are not clickable and you can not inherit from them since they are sealed, so no luck in making them clickable. I tried to just extend from Windows.UI.Xaml.Controls.Button , but those have not Location, probably because the do not belong to the Windows.UI.Xaml
