[android-developers] Re: How to set theme using resources from another application?
I managed to set the textColor from a theme from another package by using
an override of OnApplyThemeResource of the Activity:
protected override void OnApplyThemeResource(Resources.Theme theme,
int resId, bool first)
{
if (first)
{
var ctx =
ApplicationContext.CreatePackageContext("[packageidentifier]",
PackageContextFlags.Restricted);
var srcTheme = new ContextThemeWrapper(ctx,
[resourcenumber_in_other_package]);
theme.SetTo(srcTheme.Theme);
base.OnApplyThemeResource(theme, resId, first);
}
}
I am using Xamarin C#, so sorry for the 'different' syntactic sugar than
you are supposed to work with. This sadly only works if the style does not
refer to colors but having inline values for colors and then only I managed
to get the android:textColor to work... So not very usefull actually. May
this is a pointer for further investigation...

Ernstjan

Re: [android-developers] Re: How to set theme using resources from another application?
Ok, if I forget about using different drawables, and keep my external theme to modifying current's theme existing attributes only, will that be possible? I've seen the method Resources.Theme.setTo(other) which has the following desc.: Set this theme to hold the same contents as the theme other. If both of these themes are from the same Resources object, they will be identical after this function returns. If they are from different Resources, only the resources they have in common will be set in this theme. So this method isn't very useful if the themes are from the same resource, so it's used when the themes are from different resources like I'm having, but it doesn't seem to do the trick and change a single color value (textColorPrimary) I'm setting in the external theme, and after calling the setTo method, i'm getting resourceId as 0. Any pointers on how to properly use Theme.setTo? Sorry for being annoying... :) -- You received this message because you are subscribed to the Google Groups Android Developers group.

If it's your own application then read about library projects. Otherwise unless the app you are reading resources from is available under a suitable open source licence then in my opinion what you are trying to do could be infringing copyright. If the app is open source then just download it and use the resources.

[android-developers] Re: How to set theme using resources from another application?
Hi Richard, thanks for the reply. I have an app with light and dark themes defined in themes.xml. I have a setting to allow the user the select light/dark theme in the app. This works great. Now the themes are pretty heavy in graphics, since they define not only styling but different drawables as well, so I want to offer more themes like blue, green, red, etc. as external apks in Google play, like I've seen many other apps have done, so a user could install a MyApp blue theme apk, and then he'll be able to choose this theme from the main app settings. I've tried using: Resources res = pm.getResourcesForApplication(appInfo); Which gets the resources object of the external apk, but I can't seem to get and apply the theme from it using activity.setTheme(externalTheme). I've tried using: Context themedContext = activity.getApplicationContext().createPackageContext(com.myapp.blue, Context.CONTEXT_IGNORE_SECURITY); Which gets a themed context, but again, couldn't set this theme to my running activity. I've read a lot about this, but couldn't find any complete solution. Thanks, Mor.

Re: [android-developers] Re: How to set theme using resources from another application?
You can't really do this by simply pointing to a theme. The resources object is used across the view hierarchy to load resources; to set the theme from another apk you will need to have the resources coming from there, but then you won't be able to access any of your own resources that you need (like strings etc).

Re: [android-developers] Re: How to set theme using resources from another application?
Hi Dianne, thanks for the info. I've seen methods like Resources.Theme.applyStyle which capable of overriding existing attributes with a supplied style resource-id, which would have been useful if I could tell it from what resource to get the resource-id from. Isn't there a similar method that I can use to only override certain attributes in my existing applied theme? If not, could you maybe suggest a different way to approach this problem? There are lots of themed apps on Android, so I'm sure there's a way to do this. Thanks again, Mor.

Re: [android-developers] Re: How to set theme using resources from another application?
That doesn't solve the problem, which is that you are trying to create a mix of resources from two .apks and you can't currently do that. I would assume these other apps are just directly loading the bitmaps from the other .apk where they need them.
