android - 没有从 Listview OnItemClickListener 获取字符串

Question

我在 ListView 中显示数据库中的名称；这工作正常。我想实现一个 onclicklistener 的函数，将该字符串传递给另一个活动。我可以让它有点工作，但它只通过 andoid.database.sqlite... 下面是我尝试 OnItemClickLIsener 无济于事的代码。任何帮助将不胜感激。

private MyExercisesDB myExerciseDB;
private ListView myExerciseList;

@Override
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.custom_exe);

    myExerciseList = (ListView)this.findViewById(R.id.custExerLV);

    openDB();
    populateLVFromDB();
    myExerciseList.setOnItemClickListener(new OnItemClickListener()
    {

        @Override
        public void onItemClick(AdapterView<?> parent, View v, int position,long id) 
        {
            String selectedFromList = myExerciseList.getItemAtPosition(position).toString();
            GlobalVars.setVar(selectedFromList);
            startActivity(new Intent(CustomExeActivity.this, AddToCalendar.class));
        }

    });
