+/** |
|
| 26 |
+ * Adapter that simply returns row views from a list. |
|
| 27 |
+ * |
|
| 28 |
+ * If you supply a size, you must implement newView(), to |
|
| 29 |
+ * create a required view. The adapter will then cache these |
|
| 30 |
+ * views. |
|
| 31 |
+ * |
|
| 32 |
+ * If you supply a list of views in the constructor, that |
|
| 33 |
+ * list will be used directly. If any elements in the list |
|
| 34 |
+ * are null, then newView() will be called just for those |
|
| 35 |
+ * slots. |
|
| 36 |
+ * |
|
| 37 |
+ * Subclasses may also wish to override areAllItemsEnabled() |
|
| 38 |
+ * (default: false) and isEnabled() (default: false), if some |
|
| 39 |
+ * of their rows should be selectable. |
|
| 40 |
+ * |
|
| 41 |
+ * It is assumed each view is unique, and therefore will not |
|
| 42 |
+ * get recycled. |
|
| 43 |
+ * |
|
| 44 |
+ * Note that this adapter is not designed for long lists. It |
|
| 45 |
+ * is more for screens that should behave like a list. This |
|
| 46 |
+ * is particularly useful if you combine this with other |
|
| 47 |
+ * adapters (e.g., SectionedAdapter) that might have an |
|
| 48 |
+ * arbitrary number of rows, so it all appears seamless. |
