I am developing a watch face using CanvasWatchFaceService.Engine
I need to detect if watch is round or square.
I overrided onApplyWindowInsets, but it is not called.
Shall I set a specific listener or something like that?
In my experience, onApplywindowInsets only gets called when you're using Theme.DeviceDefault, or a theme descending from it. It won't get called if you're using a completely custom theme.
So in the manifest for your watch face, your application tag needs to look something like this:
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#android:style/Theme.DeviceDefault" >
Or if you have a theme for the watch face service, that will override it.
In my experience, onApplyWindowInsets is not called unless android:
isScrollContainer = "true"
is set to any view in layout.

How can I customize the appearence of xamarin.forms components?
I want each button to have the same image, for instance. Or for all systems to share the same login screen with the same background image.
I know I can do that by adding one specific screen to each platform project. But I want to be able to customize the component itself. Example: All buttons will have the same background image no matter which platform is running.
I've read these:
http://developer.xamarin.com/guides/cross-platform/xamarin-forms/custom-renderer/
http://developer.xamarin.com/guides/cross-platform/xamarin-forms/working-with/styles/
http://code.tutsplus.com/tutorials/getting-started-with-xamarinforms-customizing-user-interface--cms-22144
The most promising one seems to be the last one. Is a custom renderer the only way to accomplish this? Can't I just add an image at the shared project and it automagicaly works for all platforms?
Thanks.
It's not absolutely clear, what exactly you want to reach... but I try to answer you.
If you use a shared project (based on template "Blank App (Xamarin.Forms shared)", you can use the same page / page-definition in all of your platforms.
You can add - e.g. a login-form in the shared-folder and then call it from code (e.g. from another page in the shared folder).
If you want to create your own controls, you can create "user-controls" and use it everywhere you want (what I recommend to every user).
You do this, by create a own class (e.g. with an Entry and a Label), implement the events and then instantiate it where you want to use it. E.G.
var OeFirma = new EntryErfassung(cDefaultText: "Firma", iMaximalLaenge: 45);
where OeFirma is the name of the object-instance on the page (to access it), EntryErfassung is my own class (that contains a description-label, an Entry an error-label and more) and cDefaultText is a parameter, that overtakes and set the default-text to the Entry and iMaximalaenge is a further parameter that is overtaken whereby my class then take care, that not more then 45 Characters are accepted for this Entry).
I have e.g. created a class with a description-label, a delete-button, an Entry and a error-label ad use it on all data-entry-forms.
If you want to change the look-and-feel of a specific control for a specific platform, you can create a "custom-render" (I have done this e.g. to change the font-size to the edit specific for iOS, as the font-sinze cannot be set in the XF-Entry control).
Hope this answers your question...
To do this, you can just specific a style in the App class, (you will need to change the app class to be made up of 2 partials: App.xaml & App.xaml.cs, and then create a ResourceDictionary to hold your customisations.
<Style TargetType="Button">
<Setter Property="Image" Value="MyImage.png"/>
</Style>
Hope that helps.
Cheers,
Tristan
I am using Xamarin.Forms, shared project template.
Here, I add controls to the content page such as a Label through say framework provided StackLayout.
Now in target apps - say for iOS/Andriod, I just need to set some text for this label. I have some platform specific code where I want to change the text value for the Label created in Shared Project.
How to do that?
I understand, Custom Renderers could be used. Is there any straight forward way that I am missing here?
You can, of course, use custom renderers... but imho it would be an overkill.
I'd use OnPlatform method - something like:
myLabel.Text = Device.OnPlatform<string>("text for iOS", "text for Android", "text for Windows Phone");
You can also do the same from XAML if you wish, like shown in this article (search "OnPlatform" there):
http://developer.xamarin.com/guides/cross-platform/xamarin-forms/xaml-for-xamarin-forms/essential_xaml_syntax/
If the text you need is dynamic and you need to set it at run time from platform-specific project, than you need to assign your Label to some variable in the shared project and then reference this variable from platform projects.
I want to know if there was good way to keep my application from rotating, but let it go switch from landscape to landscape reversed?
I've only found this:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
How can I restrict my applications to those two states?
Don't wanna say it but RTM !
Here, in your Manifest add this to your activity you wanna let rotate :
android:screenOrientation="sensorLandscape"
Try adding this to your <activity> tag in the AndroidManifest.xml
android:screenOrientation="sensorLandscape"
Or if you want to do it programmatically you can add this to your activity
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
}
have a look here (duplicate)
Force an Android activity to always use landscape mode
You have to define this in the manifest
You just need to do one thing, just put android:screenOrientation="landscape" in every <activity> tag of your manifest file
Just add the following line to activities added in Manifests
<activity android:name=".youractivityName" android:screenOrientation="portrait" />
I'm attempting to localize my WinRT app. I don't need anything too fancy, so I've been using x:Uid on XAML elements in conjunction with resource files that have properties such as "PageTitleTextBox.Text" set. This method was working great until I ran into an issue with attached properties.
I've defined a few app bar buttons using similar markup to what I've seen in other examples:
<Button x:Name="AddFolderButton" Click="AddFolderButton_Tapped" x:Uid="FoldersPageAppBarAddFolderButton" AutomationProperties.Name="Test" Style="{StaticResource AppBarButtonStyle}">
<Button.Content></Button.Content>
</Button >
In this case, I'd like to localize AddFolderButton's label, currently defined by AutomationProperties.Name. I tried setting a key in my resource file to FoldersPageAppBarAddFolderButton.AutomationProperties.Name, but this fails on runtime.
Is it possible to localize this label using XAML, or do I need to do this programatically in the code-behind file?
You need to handle attached properties a bit differently, i.e. their namespace must be included in the reource key like this:
FoldersPageAppBarAddFolderButton.[using:Windows.UI.Xaml.Automation]AutomationProperties.Name
You can read more about it here.
I want to know where I can get access to the NinePatch images specifically for Monodroid. I want to change the default coloring from blue to orange (if I was doing this in Java it would already be orange).
All I need is to change an edittext so that it's default colors are different. I have seen
http://www.androidworks.com/changing-the-android-edittext-ui-widget
which is really helpful but only as far as vanilla Android is concerned. I tried following the instructions, but I found the standard orange java images, not the Mono ones, which are blue.
Minimum framework is 2.2. I know that I am getting the java images because when I go to C:\Android\android-sdk\platforms there is no android-2.2 folder.
I'm not really sure what you are referring to. Mono for Android does not ship any NinePatch images. Mono for Android simply provides a thin binding over the Java API, it does not do anything custom.
Maybe it is triggered by changing your Android target framework?
I found my answer - and thank goodnesss it did not involve changing the 9Patches!
You can make an xml in the drawable folder which describes your button, textbox, etc. and make a selector with a solid tag, pressed event, etc. (http://developer.android.com/guide/topics/resources/drawable-resource.html)
Then you can set up the colors as a constant set in the Values folder and boom! Solution!
