Remarks
An easy adapter to map static data to views defined in an XML file. You can specify the data backing the list as an ArrayList of Maps. Each entry in the ArrayList corresponds to one row in the list. The Maps contain the data for each row. You also specify an XML file that defines the views used to display the row, and a mapping from keys in the Map to specific views.
Binding data to views occurs in two phases. First, if a android.widget.SimpleAdapter.ViewBinder is available, ViewBinder#setViewValue(android.view.View, Object, String) is invoked. If the returned value is true, binding has occurred. If the returned value is false, the following views are then tried in order: <ul> <li> A view that implements Checkable (e.g. CheckBox). The expected bind value is a boolean. <li> TextView. The expected bind value is a string and #setViewText(TextView, String) is invoked. <li> ImageView. The expected bind value is a resource id or a string and #setViewImage(ImageView, int) or #setViewImage(ImageView, String) is invoked. </ul> If no appropriate binding can be found, an IllegalStateException is thrown.

Methods
| Name | Description |
|---|---|

| Clone() |
Creates and returns a copy of this object. (Inherited from Object) |
| Dispose() |
Releases the resources held by this Java peer. (Inherited from Object) |

| GetAutofillOptions() |
Gets a string representation of the adapter data that can help AutofillService autofill the view backed by the adapter. It should only be set (i.e., non- null if the values do not represent PII (Personally Identifiable Information - sensitive data such as email addresses, credit card numbers, passwords, etc...). For example, it's ok to return a list of month names, but not a list of usernames. A good rule of thumb is that if the adapter data comes from static resources, such data is not PII - see ViewStructure.setDataIsSensitive(boolean) for more info. It should only be set (i.e., non- null if the values do not represent PII (Personally Identifiable Information - sensitive data such as email addresses, credit card numbers, passwords, etc...).
