 /**
- * A concrete BaseAdapter that is backed by an array of arbitrary
- * objects.  By default this class expects that the provided resource id references
- * a single TextView.  If you want to use a more complex layout, use the constructors that
- * also takes a field id.  That field id should reference a TextView in the larger layout
- * resource.
- *
- * <p>However the TextView is referenced, it will be filled with the toString() of each object in
- * the array. You can add lists or arrays of custom objects. Override the toString() method
- * of your objects to determine what text will be displayed for the item in the list.
- *
- * <p>To use something other than TextViews for the array display, for instance, ImageViews,
- * or to have some of data besides toString() results fill the views,
- * override {@link #getView(int, View, ViewGroup)} to return the type of view you want.
+ * You can use this adapter to provide views for an {@link 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
+ * {@link ListView} or {@link Spinner}.
+ * <p>
+ * By default, the array adapter creates a view by calling {@link 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 {@link #getView(int, View, ViewGroup)}
+ * and inflate a view resource.
+ * For a code example, see
+ * the <a href="https://developer.android.com/samples/CustomChoiceList/index.html">
+ * CustomChoiceList</a> sample.
+ * </p>
+ * <p>
+ * For an example of using an array adapter with a ListView, see the
+ * <a href="{@docRoot}guide/topics/ui/declaring-layout.html#AdapterViews">
+ * Adapter Views</a> guide.
+ * </p>
+ * <p>
+ * For an example of using an array adapter with a Spinner, see the
+ * <a href="{@docRoot}guide/topics/ui/controls/spinner.html">Spinners</a> guide.
+ * </p>
+ * <p class="note"><strong>Note:</strong>
+ * If you are considering using array adapter with a ListView, consider using
+ * {@link android.support.v7.widget.RecyclerView} instead.
+ * RecyclerView offers similar features with better performance and more flexibility than
+ * ListView provides.
+ * See the
+ * <a href="https://developer.android.com/guide/topics/ui/layout/recyclerview.html">
+ * Recycler View</a> guide.</p>
