我想从列表视图中删除项目

Question

The problem I'm having is that whenever I delete , only the last item from the ListView is being deleted. I remove the item from my arraylist and call adapter.notifyDataSetChanged() . Is there anything which I'm missing? Also , when I try to delete too many items I get an arrayIndexOutOfBounds exception , but I'm passing the index I recieve. Why I am getting this exception?

public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {
            HistoryItem item = historyItems.get(index);
            switch (index) {
                case 0:
                    //ToDo edit
                    //Toast.makeText(History.this,"pos "+position+" index "+index,Toast.LENGTH_SHORT).show();
                    break;
                case 1:
                    //ToDo delete

                    historyItems.remove(item);
                    adapter.notifyDataSetChanged();

Answer 1

You are using index which is position of Edit or Delete buttons.. You have to use Position instead of index to delete item from list The problem is at HistoryItem item = historyItems.get(index);

Solution:

HistoryItem item = historyItems.get(position);

Answer 2

Don't use index use position

public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {
                HistoryItem item = historyItems.get(position);
                switch (index) {
                    case 0:
                        //ToDo edit
                        //Toast.makeText(History.this,"pos "+position+" index "+index,Toast.LENGTH_SHORT).show();
                        break;
                    case 1:
                        //ToDo delete

                        historyItems.remove(position);
                        adapter.notifyDataSetChanged();

Answer 3

You are using index variable to remove items. You need to use position variable to get the selected items from history list

Change this line in code

HistoryItem item = historyItems.get(position);
