Returns true if the given model is a of a recognized type that this loader can probably load.
public final Context context
public MediaStoreImageThumbLoader(Context context)
public ModelLoader.LoadData<InputStream> buildLoadData(Uri model, int width, int height, Options options)
DataFetcherrequired to decode the resource represented by this model, as well as a set of
Keysthat identify the data loaded by the
DataFetcheras well as an optional list of alternate keys from which equivalent data can be loaded. The
DataFetcherwill not be used if the resource is already cached.
Note - If no valid data fetcher can be returned (for example if a model has a null URL), then it is acceptable to return a null data fetcher from this method.
model- The model representing the resource.
width- The width in pixels of the view or target the resource will be loaded into, or
Target.SIZE_ORIGINALto indicate that the resource should be loaded at its original width.
height- The height in pixels of the view or target the resource will be loaded into, or
Target.SIZE_ORIGINALto indicate that the resource should be loaded at its original height.
public boolean handles(Uri model)
For example, you may want multiple Uri -> InputStream loaders. One might handle media store Uris, another might handle asset Uris, and a third might handle file Uris etc.
This method is generally expected to do no I/O and complete quickly, so best effort
results are acceptable.
ModelLoaders that return true from this method may
ModelLoader.buildLoadData(Object, int, int, Options)
