public ViewRecycler(android.content.Context context)

Creates a new recycler, which allows to cache views in order to be able to reuse them later, instead of inflating new instances.

Parameters:

context - The context, which should be used by the recycler, as an instance of the class Context. The context may not be null

ViewRecycler

public ViewRecycler(android.view.LayoutInflater inflater)

Creates a new recycler, which allows to cache views in order to be able to reuse them later, instead of inflating new instances.

Parameters:

inflater - The layout inflater, which should be used to inflate views, as an instance of the class LayoutInflater. The layout inflater may not be null

Method Detail

inflate

@SafeVarargs
public final <any> inflate(ItemType item,
                                        android.view.ViewGroup parent,
                                        ParamType... params)

Inflates the view, which is used to visualize a specific item. If possible, an unused view will be retrieved from the cache, instead of inflating a new instance.

Parameters:

item - The item, which should be visualized by the inflated view, as an instance of the generic type ItemType. The item may not be null

parent - The parent of the inflated view as an instance of the class ViewGroup or null, if no parent is available

params - An array, which may contain optional parameters, as an array of the generic type ParamType or an empty array, if no optional parameters are available

Returns:

A pair, which contains the view, which is used to visualize the given item, as well as a boolean value, which indicates, whether a new view has been inflated, or if an unused view has been reused from the cache, as an instance of the class Pair. The pair may not be null

inflate

@SafeVarargs
public final <any> inflate(ItemType item,
                                        android.view.ViewGroup parent,
                                        boolean useCache,
                                        ParamType... params)

Inflates the view, which is used to visualize a specific item.

Parameters:

item - The item, which should be visualized by the inflated view, as an instance of the generic type ItemType. The item may not be null

parent - The parent of the inflated view as an instance of the class ViewGroup or null, if no parent is available

useCache - True, if an unused view should retrieved from the cache, if possible, false, if a new instance should be inflated instead

params - An array, which may contain optional parameters, as an array of the generic type ParamType or an empty array, if no optional parameters are available

Returns:

A pair, which contains the view, which is used to visualize the given item, as well as a boolean value, which indicates, whether a new view has been inflated, or if an unused view has been reused from the cache, as an instance of the class Pair. The pair may not be null

inflate

@SafeVarargs
public final <any> inflate(ItemType item,
                                        boolean useCache,
