Method Detail

setItemBinding

public void setItemBinding(ItemBinding<T> itemBinding)

Description copied from interface: BindingCollectionAdapter

Sets the item biding for the adapter.

Specified by:

setItemBinding in interface BindingCollectionAdapter<T>

setLifecycleOwner

public void setLifecycleOwner(LifecycleOwner lifecycleOwner)

Sets the lifecycle owner of this adapter to work with androidx.lifecycle.LiveData. This is normally not necessary, but due to an androidx limitation, you need to set this if the containing view is not using databinding.

getItemBinding

public ItemBinding<T> getItemBinding()

Description copied from interface: BindingCollectionAdapter

Returns the ItemBinding that the adapter that was set.

Specified by:

getItemBinding in interface BindingCollectionAdapter<T>

setDropDownItemLayout

public void setDropDownItemLayout(int layoutRes)

Set a different layout to show for getDropDownView(int, View, ViewGroup). If this is null, it will default to getView(int, View, ViewGroup).

setItems

public void setItems(java.util.List<T> items)

Description copied from interface: BindingCollectionAdapter

Sets the adapter's items. These items will be displayed based on the ItemBinding. If you pass in an ObservableList the adapter will also update itself based on that list's changes.
Note that the adapter will keep a direct reference to the given list. Any changes to it must happen on the main thread. Additionally, if you are not using an ObservableList, you must call notifyDataSetChanged() or one of the related methods.

Specified by:

setItems in interface BindingCollectionAdapter<T>

getAdapterItem

public T getAdapterItem(int position)

Description copied from interface: BindingCollectionAdapter

Returns the item in the adapter given position. This is useful for accessing items in the adapter.

Specified by:

onCreateBinding

public ViewDataBinding onCreateBinding(LayoutInflater inflater,
                                       int layoutRes,
                                       ViewGroup viewGroup)

Description copied from interface: BindingCollectionAdapter

Called to create a binding. An implementation should create a binding inflated with the given layoutId and viewGroup. A subclass may override this and cast the result to a specific layout binding to get at the generated view fields.

Specified by:

onCreateBinding in interface BindingCollectionAdapter<T>

onBindBinding

public void onBindBinding(ViewDataBinding binding,
                          int variableId,

                          T item)

Description copied from interface: BindingCollectionAdapter
