java.lang.Object
- com.bumptech.glide.request.target.CustomTarget<T>

Type Parameters:

T - The type of resource that will be loaded (e.g. Bitmap).

All Implemented Interfaces:

LifecycleListener, Target<T>

Direct Known Subclasses:

AppWidgetTarget, NotificationTarget, PreloadTarget
```
public abstract class CustomTarget<T>
extends java.lang.Object
implements Target<T>
```
A base Target for loading resources (Bitmap, Drawable etc) that are used outside of Views.
If you're loading a resource into a View, use RequestBuilder.into(ImageView), a subclass of ImageViewTarget, or CustomViewTarget. Using this class to load resources into Views can prevent Glide from correctly cancelling any previous loads, which may result in incorrect images appearing in the view, especially in scrolling views like androidx.recyclerview.widget.RecyclerView.
You MUST implement Target.onLoadCleared(Drawable) and ensure that all references to any resource passed into the target in Target.onResourceReady(Object, Transition) are removed before Target.onLoadCleared(Drawable) completes. Failing to do so can result in graphical corruption, crashes caused by recycled Bitmaps, and other undefined behavior. It is never safe to leave Target.onLoadCleared(Drawable) unimplemented or empty. Even if you do not manually clear this Target, Glide may do so automatically after certain lifecycle events in Fragments and Activitys.
This class can only be used with Target.SIZE_ORIGINAL or when the desired resource dimensions are known when the Target is created. If you'd like to run some asynchronous process and make full use of getSize(SizeReadyCallback) and SizeReadyCallback, extend Target directly instead of using this class.

- Constructor Detail
  - CustomTarget
```
public CustomTarget()
```
    Creates a new CustomTarget that will attempt to load the resource in its original size.
    This constructor can cause very memory inefficient loads if the resource is large and can cause OOMs. It's provided as a convenience for when you'd like to specify dimensions with BaseRequestOptions.override(int). In all other cases, prefer CustomTarget(int, int).
  - CustomTarget
```
public CustomTarget(int width,
                    int height)
```
    Creates a new CustomTarget that will return the given width and height as the requested size (unless overridden by BaseRequestOptions.override(int) in the request).
    
    Parameters:
    
    width - The requested width (> 0, or == Target.SIZE_ORIGINAL).
    
    height - The requested height (> 0, or == Target.SIZE_ORIGINAL).
    
    Throws:
    
    java.lang.IllegalArgumentException - if width/height doesn't meet the requirement: > 0, or == Target.SIZE_ORIGINAL

  - onStart
```
public void onStart()
```
    Description copied from interface: LifecycleListener
    
    Callback for when Fragment.onStart()} or Activity.onStart() is called.
    
    Specified by:
    
    onStart in interface LifecycleListener
  - onStop
```
public void onStop()
```
    Description copied from interface: LifecycleListener
    
    Callback for when Fragment.onStop()} or Activity.onStop()} is called.
    
    Specified by:
    
    onStop in interface LifecycleListener
  - onDestroy
```
public void onDestroy()
```
    Description copied from interface: LifecycleListener
    
    Callback for when Fragment.onDestroy()} or Activity.onDestroy() is called.
    
    Specified by:
    
    onDestroy in interface LifecycleListener
  - onLoadStarted
```
public void onLoadStarted(@Nullable
                          android.graphics.drawable.Drawable placeholder)
```
    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<T>
    
    Parameters:
    
    placeholder - The placeholder drawable to optionally show, or null.
  - onLoadFailed
```
public void onLoadFailed(@Nullable
                         android.graphics.drawable.Drawable errorDrawable)
```
    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<T>
    
    Parameters:
    
    errorDrawable - The error drawable to optionally show, or null.
  - getSize
```
public final void getSize(@NonNull
                          SizeReadyCallback cb)
```
    Description copied from interface: Target
    
    A method to retrieve the size of this target.
    
    Specified by:
    
    getSize in interface Target<T>
    
    Parameters:
    
    cb - The callback that must be called when the size of the target has been determined
  - removeCallback
```
public final void removeCallback(@NonNull
                                 SizeReadyCallback cb)
```
    Description copied from interface: Target
    
    Removes the given callback from the pending set if it's still retained.
    
    Specified by:
    
    removeCallback in interface Target<T>

    cb - The callback to remove.
  - setRequest

                             Request request)
