Class BaseTarget<Z>

java.lang.Object

com.bumptech.glide.request.target.BaseTarget<Z>

Type Parameters:

Z - The type of resource that will be received by this target.

All Implemented Interfaces:

LifecycleListener, Target<Z>

Direct Known Subclasses:

SimpleTarget, ViewTarget

Deprecated.

Use CustomViewTarget if loading the content into a view, the download API if in the background (http://bumptech.github.io/glide/doc/getting-started.html#background-threads), or a a fully implemented Target for any specialized use-cases. Using BaseView is unsafe if the user does not implement onLoadCleared(android.graphics.drawable.Drawable), resulting in recycled bitmaps being referenced from the UI and hard to root-cause crashes.

@Deprecated
public abstract class BaseTarget<Z>
extends java.lang.Object
implements Target<Z>

A base Target for loading Resources that provides basic or empty implementations for most methods.

For maximum efficiency, clear this target when you have finished using or displaying the Resource loaded into it using RequestManager.clear(Target).

For loading Resources into Views, ViewTarget or ImageViewTarget are preferable.

onLoadCleared

public void onLoadCleared(@Nullable
                          android.graphics.drawable.Drawable placeholder)

Deprecated.

Description copied from interface: Target

A mandatory lifecycle callback that is called when a load is cancelled and its resources are freed.

You must ensure that any current Drawable received in Target.onResourceReady(Object, Transition) is no longer used before redrawing the container (usually a View) or changing its visibility.

Specified by:

onLoadCleared in interface Target<Z>

Parameters:

placeholder - The placeholder drawable to optionally show, or null.

onLoadStarted

public void onLoadStarted(@Nullable
                          android.graphics.drawable.Drawable placeholder)

Deprecated.

Description copied from interface: Target

A lifecycle callback that is called when a load is started.

Note - This may not be called for every load, it is possible for example for loads to fail before the load starts (when the model object is null).

Note - This method may be called multiple times before any other lifecycle method is called. Loads can be paused and restarted due to lifecycle or connectivity events and each restart may cause a call here.

Specified by:

onLoadStarted in interface Target<Z>

Parameters:

placeholder - The placeholder drawable to optionally show, or null.

onLoadFailed

public void onLoadFailed(@Nullable
                         android.graphics.drawable.Drawable errorDrawable)

Deprecated.

Description copied from interface: Target

A mandatory lifecycle callback that is called when a load fails.

Note - This may be called before Target.onLoadStarted(android.graphics.drawable.Drawable) if the model object is null.

You must ensure that any current Drawable received in Target.onResourceReady(Object, Transition) is no longer used before redrawing the container (usually a View) or changing its visibility.

Specified by:

onLoadFailed in interface Target<Z>

Parameters:

errorDrawable - The error drawable to optionally show, or null.
