+     * WARNING: This is a workaround for a touch mode issue.
+     *
+     * Touch mode is propagated lazily to windows. This causes problems in
+     * the following scenario:
+     * - 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
+     * returns super.isInTouchMode().

-         * WARNING: This is a workaround for a touch mode issue.
-         *
-         * Touch mode is propagated lazily to windows. This causes problems in
-         * the following scenario:
-         * - 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
-         * returns super.isInTouchMode().
