Android求助

我写了一个Listview如下：
     ListView shourulv = (ListView) findViewById(R.id.shourulv);
    List<HashMap<String, Object>> data1 = new ArrayList<HashMap<String, Object>>();
    for (Outcome outcome1 : outcomes)
    {
     HashMap<String, Object> item1 = new HashMap<String, Object>();
     item1.put("outcomeid", outcome1.getOutcomeid());
     item1.put("name1", outcome1.getName1());
     item1.put("money1", outcome1.getMoney1());
     item1.put("message1", outcome1.getMessage1());
     item1.put("time1", outcome1.getTime1());
     data1.add(item1);
    }
    // 适配器的选择
    SimpleAdapter adapter = new SimpleAdapter(MingxiActivity.this, data1, R.layout.item, new String[]
    { "outcomeid", "name1", "money1", "message1", "time1" }, new int[]
    { R.id.iditem, R.id.namesr, R.id.moneysr, R.id.messagesr, R.id.timesr });
    shourulv.setAdapter(adapter);
    // 为ListView添加点击事件
    shourulv.setOnItemClickListener(new OnItemClickListener
    {
     @Override
     public void onItemClick(AdapterView<?> parent, View view, int position, long id)
     {
      ListView lView = (ListView) parent
      HashMap<String, Object> item3 = (HashMap<String, Object>) lView.getItemAtPosition(position);      String a=Stirng.valueOf(item3.get(outcomeid));    dialog(a);    }
    });
   对话框如下： protected void dialog1(final Integer outcomeid5)
 { AlertDialog.Builder builder = new Builder(MingxiActivity.this);
 builder.setMessage("你选择的是？");
 builder.setTitle("欢迎");
 builder.setPositiveButton("删除", new
 android.content.DialogInterface.OnClickListener()
 {
 @Override
 public void onClick(DialogInterface dialog, int which)
 { dialog.dismiss();
 outcometable.delete(outcomeid5); }
 });
 builder.setNegativeButton("修改", new
 android.content.DialogInterface.OnClickListener()
 {
 @Override
 public void onClick(DialogInterface dialog, int which)
 {
 dialog.dismiss(); }
 });
 builder.create().show();
 }删除数据方法如下： public void delete(String id )
 {
  SQLiteDatabase db = financialManagementSystemData.getWritableDatabase();
  db.execSQL("delete from outcome where outcomeid=? ", new Object[]
  { id.toString()});
 }问题是我点击删除按钮时出错了，请问问题出现在哪里？
