- * WARNING: This is a workaround for a touch mode issue.

- * - Type something in the AutoCompleteTextView and get some results
- * - Move down with the d-pad to select an item in the list
- * - Move up with the d-pad until the selection disappears
- * - Type more text in the AutoCompleteTextView *using the soft keyboard*
- * and get new results; you are now in touch mode
- * - The selection comes back on the first item in the list, even though
- * the list is supposed to be in touch mode
- *
- * Using the soft keyboard triggers the touch mode change but that change
- * is propagated to our window only after the first list layout, therefore
- * after the list attempts to resurrect the selection.
- *
- * The trick to work around this issue is to pretend the list is in touch
- * mode when we know that the selection should not appear, that is when
- * we know the user moved the selection away from the list.
- *
- * This boolean is set to true whenever we explicitly hide the list's
- * selection and reset to false whenever we know the user moved the
- * selection back to the list.
- *
- * When this boolean is true, isInTouchMode() returns true, otherwise it
