java - 如何使用 OnItemLongClickListener() 从 SQLite 创建的 ListView 中删除项目？

Question

我在使用 SimpleCursorAdapter 创建的 ListView 中找不到删除的答案所以我在 fragment 中制作了这个 ListView ，这是代码

final Cursor cursor = myDb.cautarevenituri();

    // The desired columns to be bound
    final String[] columns = new String[] {
            DatabaseHelper.COL_2,
            DatabaseHelper.COL_3
    };

    int[] toviewids = new int[] { R.id.nume_item,R.id.valoare_item};
    dataAdapter = new SimpleCursorAdapter(getActivity().getBaseContext(),R.layout.item_layout,cursor,columns,toviewids,0);
    //
    final ListView listView = (ListView)getView().findViewById(R.id.listView_venituri);

    listView.setAdapter(dataAdapter);
    listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
        @Override
        public boolean onItemLongClick(AdapterView<?> parent, View view,
                                       int position, long arg3) {
            Toast.makeText(getActivity(), " " + position, Toast.LENGTH_LONG).show();

            //delete from listview in database and listview too??
            //
            //

            return false;
        }

    });

谢谢。
