ResourcesLoader
open class ResourcesLoader
| kotlin.Any | |
| ↳ | android.content.res.loader.ResourcesLoader |
A container for supplying ResourcesProvider(s) to Resources objects.
ResourcesLoader(s) are added to Resources objects to supply additional resources and assets or modify the values of existing resources and assets. Multiple Resources objects can share the same ResourcesLoaders and ResourcesProviders. Changes to the list of ResourcesProvider(s) a loader contains propagates to all Resources objects that use the loader.
Loaders must be added to Resources objects in increasing precedence order. A loader will override the resources and assets of loaders added before itself.
Providers retrieved with getProviders() are listed in increasing precedence order. A provider will override the resources and assets of providers listed before itself.
Modifying the list of providers a loader contains or the list of loaders a Resources object contains can cause lock contention with the UI thread. APIs that modify the lists of loaders or providers should only be used on the UI thread. Providers can be instantiated on any thread without causing lock contention.

open fun clearProviders(): Unit
Removes all ResourcesProvider(s).
This should only be called from the UI thread to avoid lock contention when propagating provider changes.
getProviders
open fun getProviders(): MutableList<ResourcesProvider!>
