Class BitmapDrawableResource

java.lang.Object

com.bumptech.glide.load.resource.drawable.DrawableResource<BitmapDrawable>

com.bumptech.glide.load.resource.bitmap.BitmapDrawableResource

All Implemented Interfaces:

Initializable, Resource<BitmapDrawable>

public class BitmapDrawableResource
extends DrawableResource<BitmapDrawable>
implements Initializable

A Resource that wraps an BitmapDrawable

This class ensures that every call to DrawableResource.get()} always returns a new BitmapDrawable to avoid rendering issues if used in multiple views and is also responsible for returning the underlying Bitmap to the given BitmapPool when the resource is recycled.

Method Detail

getResourceClass

public Class<BitmapDrawable> getResourceClass()

Description copied from interface: Resource

Returns the Class of the wrapped resource.

Specified by:

getResourceClass in interface Resource<BitmapDrawable>

getSize

public int getSize()

Description copied from interface: Resource

Returns the size in bytes of the wrapped resource to use to determine how much of the memory cache this resource uses.

Specified by:

getSize in interface Resource<BitmapDrawable>

recycle

public void recycle()

Description copied from interface: Resource

Cleans up and recycles internal resources.

It is only safe to call this method if there are no current resource consumers and if this method has not yet been called. Typically this occurs at one of two times:

• During a resource load when the resource is transformed or transcoded before any consumer have ever had access to this resource
• After all consumers have released this resource and it has been evicted from the cache

For most users of this class, the only time this method should ever be called is during transformations or transcoders, the framework will call this method when all consumers have released this resource and it has been evicted from the cache.

Specified by:

recycle in interface Resource<BitmapDrawable>

initialize

public void initialize()

Description copied from interface: Initializable

Called on a background thread so the Resource can do some eager initialization.

Specified by:

initialize in interface Initializable

Overrides:

initialize in class DrawableResource<BitmapDrawable>
