Examples with Configuration android.content.res.Configuration used on opensource projects

Example 71 with Configuration

use of android.content.res.Configuration in project android_frameworks_base by ResurrectionRemix.

the class ResourcesManager method getResources.

/**
     * Gets or creates a new Resources object associated with the IBinder token. References returned
     * by this method live as long as the Activity, meaning they can be cached and used by the
     * Activity even after a configuration change. If any other parameter is changed
     * (resDir, splitResDirs, overrideConfig) for a given Activity, the same Resources object
     * is updated and handed back to the caller. However, changing the class loader will result in a
     * new Resources object.
     * <p/>
     * If activityToken is null, a cached Resources object will be returned if it matches the
     * input parameters. Otherwise a new Resources object that satisfies these parameters is
     * returned.
     *
     * @param activityToken Represents an Activity. If null, global resources are assumed.
     * @param resDir The base resource path. Can be null (only framework resources will be loaded).
     * @param splitResDirs An array of split resource paths. Can be null.
     * @param overlayDirs An array of overlay paths. Can be null.
     * @param libDirs An array of resource library paths. Can be null.
     * @param displayId The ID of the display for which to create the resources.
     * @param overrideConfig The configuration to apply on top of the base configuration. Can be
     * null. Mostly used with Activities that are in multi-window which may override width and
     * height properties from the base config.
     * @param compatInfo The compatibility settings to use. Cannot be null. A default to use is
     * {@link CompatibilityInfo#DEFAULT_COMPATIBILITY_INFO}.
     * @param classLoader The class loader to use when inflating Resources. If null, the
     * {@link ClassLoader#getSystemClassLoader()} is used.
     * @return a Resources object from which to access resources.
