Android - Removing Multiple Items From List View

Problem Solved: For anyone in the future who has this problem, I found this this nice tutorial: http://www.androidbegin.com/tutorial/android-delete-multiple-selected-items-listview

Solution 1:

UPDATE:

change your sellList to contain Strings

private ArrayList<String> sellList;

@Override
publicvoidonItemClick(AdapterView<?> parent, View view,
            int position, long id) {
    String item = adapter.getItem( position );
    if (!sellList.contains( item )) {
        listview.setItemChecked(position, true);
        view.setBackgroundColor(Color.BLUE);
        sellList.add( item );
    } else {
        listview.setItemChecked(position, false);
        view.setBackgroundColor(Color.TRANSPARENT);
        sellList.remove( item );
    }
}

then

        for (String item : sellList) {
            adapter.remove( item );
        }
        sellList.clear();
        adapter.notifyDataSetChanged();
        listview.clearChoices();

Solution 2:

The list you delete from is not the one the adapter is using. When you pass list into your adapter it is copied. You need to delete from the list that the adapter is using.

Solution 3:

in onActionItemClicked and switch method:

case R.id.selectAll:
    for (int i = 0; i < listView.getAdapter().getCount(); i++) {
       customAdapter.selectAll(i);
       listView.setItemChecked(i, true);
                            }

and in the youradapter create:

publicvoidselectAll(int i){
  mSelectedItemsIds.put(i, false);
  }
