将SQLite中的值汇总到EditText中

Question

在我的应用程序中我有一个包含项目名称及其升的sql数据库，我有一个打印出每行的列表视图，在每行中我打印每个项目的名称和加号和减号按钮。按下按钮时，我希望将该项目的升数添加到运行总计中。我不能让它工作，我真的很感激我能得到的任何帮助。

目前我正在将每个项目的升数读入变量'test'然后我通过界面发送此变量以在edittext中打印但是当我单击一个按钮时，editText不会得到它只是打印出来的升某种字符串。

这是我试图在升读中读取的适配器，我应该尝试在这里或其他地方这样做吗？

我的界面

//interface to change the editText(running totals) on the main activity
public interface MyAdapterInterface {

public void updateEditText(TextView value);
}
