Encountered IndexOutOfBoundException while removing items from ListView in Android?

I have one simple_list_item_multiple_choice listview in my layout and i am trying to remove all the selected items from it. I know how to delete it but i am having two major problems while deleting the items :-

1. My program isn't deleting开发者_开发技巧 more than 2 items like if i selected 4 items then only 2 will be deleted and sometime its even deleting the wrong items.

2. When i debug my code i found Array IndexOutOfBoundException in my code and as far as i know there is no exception like this in my code and its all because of deleting the wrong or less items.

here is my code:-

public void onClick(View view)
{
    SparseBooleanArray checkedPositions = new SparseBooleanArray();
    checkedPositions.clear();
    checkedPositions = lv.getCheckedItemPositions();
    int size = checkedPositions.size();
    if(size != 0)
    {
        try
        {
        for(int i = 0; i < size; i++)
        {
            if(checkedPositions.valueAt(i))
            {
                list.remove(checkedPositions.keyAt(i));
                notes.notifyDataSetChanged();
                lv.setItemChecked(i,false);
            }
        }}catch (IndexOutOfBoundsException ie)
        {}
    }
        else{}
}

I caught the exception only for debugging purpose. Thanks in advance but please help because i am stuck at this part since last two days.

Each time you remove an item from the array at the lower lever, the total count is being reduced by 1. If you had 4 items to remove [ 0, 1, 2, 3], and you remove items starting with item 0, you have [0, 1, 2], then you remove item at 1, and you have [0, 1], if you try to remove item at index 2 which does not exist you will get an error. Try count down instead of up like this

for(int i = size; i > 0; --i)
{
  if(checkedPositions.valueAt(i))
  {
    list.remove(checkedPositions.keyAt(i));
    notes.notifyDataSetChanged();
    lv.setItemChecked(i,false);
  }
}

for(int i = size-1 ; i >= 0; i--) 
{
  if(checkedPositions.valueAt(i))
  {
    list.remove(checkedPositions.keyAt(i));
    //lv.setItemChecked(checkedPositions.keyAt(i),false);
  }
}
notes.notifyDataSetChanged();

From the look of it, you should change this

for(int i = 0; i <= size; i++)

to

for(int i = 0; i < size; i++)
