Example 81 with SparseBooleanArray

use of android.util.SparseBooleanArray in project JamsMusicPlayer by psaravan.

the class DragSortListView method removeCheckState.

/**
     * Use this when an item has been deleted, to move the check state of all
     * following items up one step. If you have a choiceMode which is not none,
     * this method must be called when the order of items changes in an
     * underlying adapter which does not have stable IDs (see
     * {@link ListAdapter#hasStableIds()}). This is because without IDs, the
     * ListView has no way of knowing which items have moved where, and cannot
     * update the check state accordingly.
     * 
     * See also further comments on {@link #moveCheckState(int, int)}.
