onResourceReady

public void onResourceReady(@NonNull
 Z resource,
 @Nullable
 Transition<? super Z> transition)

Description copied from interface: Target

The method that will be called when the resource load has finished.

This may be called multiple times both within a single load and also across different loads if the Target object is re-used.

Within a single load this may be called multiple times for reasons that include:

• The load uses one or more thumbnails. Each time a thumbnail load completes successfully and no higher priority load has finished, this method will be called with the thumbnail resource. See RequestBuilder.thumbnail(com.bumptech.glide.RequestBuilder).
• The load is paused and restarted. This can happen automatically in response to connectivity changes or the Activity / Fragment lifecycle. It can also happen if RequestManager.pauseRequests() is called manually.

Specified by:

onResourceReady in interface Target<Z>

Parameters:

resource - the loaded resource.

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

Overrides:

onStart in class BaseTarget<Z>

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

Overrides:

onStop in class BaseTarget<Z>

setResource

protected abstract void setResource(@Nullable
 Z resource)
