android-删除项目SwipeListView错误

Question

我遇到了问题我无法解决。谢谢你的帮助。

我尝试删除SwipeMenuListView上的某个项目但我不能这样做。 这是我的代码;

 list= (SwipeMenuListView) findViewById(R.id.listView1);

    groups = new UserData(getApplication()).getUserGroups();
    if (groups == null)
        groups = new ArrayList<String>();
    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, groups.toArray(new String[0]));
    list.setAdapter(adapter);


list.setOnMenuItemClickListener(new SwipeMenuListView.OnMenuItemClickListener() {
        @Override
        public boolean onMenuItemClick(int position, SwipeMenu menu, int index) {
            switch (index) {
                case 0:
                    try {
                        groups.remove(position);
                        adapter.notifyDataSetChanged();
                        Log.d("TAG","onMenuClickListener"+index+" position is "+ position);
                        break;
                    }
                    catch (Exception e) {
                        Log.d("TAG","error  " + e);
                    }

            }
            // false : close the menu; true : not close the menu
            return false;
        }
    });

    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                                long id) {

            Intent intent = new Intent(GroupActivity.this, MapsActivity.class);
            intent.putExtra("GRUPID", groups.get(position));
            startActivity(intent);

        }
    });

当我尝试删除项目时，项目未删除，第二次按下按钮时发生错误;

  

java.lang.IndexOutOfBoundsException：索引1无效，大小为1.

我认为该项目已删除但仍会显示。

再次感谢您的帮助。
