ArrayAdapterCompat2 (ui 1.7.0 API)

java.lang.Object
- android.widget.BaseAdapter
- - com.mcxiaoke.next.ui.widget.ArrayAdapterCompat2<T>

所有已实现的接口:

android.widget.Adapter, android.widget.Filterable, android.widget.ListAdapter, android.widget.SpinnerAdapter
```
public abstract class ArrayAdapterCompat2<T>
extends android.widget.BaseAdapter
implements android.widget.Filterable
```
You can use this adapter to provide views for an AdapterView, Returns a view for each object in a collection of data objects you provide, and can be used with list-based user interface widgets such as ListView or Spinner.
By default, the array adapter creates a view by calling Object.toString() on each data object in the collection you provide, and places the result in a TextView. You may also customize what type of view is used for the data object in the collection. To customize what type of view is used for the data object, override Adapter.getView(int, View, ViewGroup) and inflate a view resource. For a code example, see the CustomChoiceList sample.

For an example of using an array adapter with a ListView, see the Adapter Views guide.

For an example of using an array adapter with a Spinner, see the Spinners guide.

Note: If you are considering using array adapter with a ListView, consider using androidx.recyclerview.widget.RecyclerView instead. RecyclerView offers similar features with better performance and more flexibility than ListView provides. See the Recycler View guide.

```
public ArrayAdapterCompat2(android.content.Context context,
                           T[] objects)
```
    Constructor
    
    参数:
    
    context - The current context.
    
    objects - The objects to represent in the ListView.
- 方法详细资料
  - add
```
public void add(T object)
```
    Adds the specified object at the end of the array.
    
    参数:
    
    object - The object to add at the end of the array.
  - addAll
```
public void addAll(java.util.Collection<? extends T> collection)
```
    Adds the specified Collection at the end of the array.
    
    参数:
    
    collection - The Collection to add at the end of the array.
    
    抛出:
    
    java.lang.UnsupportedOperationException - if the addAll operation is not supported by this list
    
    java.lang.ClassCastException - if the class of an element of the specified collection prevents it from being added to this list
    
    java.lang.NullPointerException - if the specified collection contains one or more null elements and this list does not permit null elements, or if the specified collection is null
    
    java.lang.IllegalArgumentException - if some property of an element of the specified collection prevents it from being added to this list
  - addAll
```
public void addAll(T... items)
```
    Adds the specified items at the end of the array.
    
    参数:
    
    items - The items to add at the end of the array.
  - insert
```
public void insert(T object,
                   int index)
```
    Inserts the specified object at the specified index in the array.
    
    参数:
    
    object - The object to insert into the array.
    
    index - The index at which the object must be inserted.
  - remove
```
public void remove(T object)
```
    Removes the specified object from the array.
    
    参数:
    
    object - The object to remove.
  - clear
```
public void clear()
```
    Remove all elements from the list.
  - sort
```
public void sort(java.util.Comparator<? super T> comparator)
```
    Sorts the content of this adapter using the specified comparator.
    
    参数:
    
    comparator - The comparator used to sort the objects contained in this adapter.
  - notifyDataSetChanged
```
public void notifyDataSetChanged()
```
    覆盖:
    
    notifyDataSetChanged 在类中 android.widget.BaseAdapter
  - setNotifyOnChange
```
public void setNotifyOnChange(boolean notifyOnChange)
```
    Control whether methods that change the list (add(T), addAll(Collection), addAll(Object[]), insert(T, int), remove(T), clear(), sort(Comparator)) automatically call notifyDataSetChanged(). If set to false, caller must manually call notifyDataSetChanged() to have the changes reflected in the attached view. The default is true, and calling notifyDataSetChanged() resets the flag to true.
    
    参数:
    
    notifyOnChange - if true, modifications to the list will automatically call notifyDataSetChanged()
  - getContext
```
public android.content.Context getContext()
```
    Returns the context associated with this array adapter. The context is used to create views from the resource passed to the constructor.
    
    返回:
    
    The Context associated with this adapter.
