Question

我目前有三个按钮，一个用于更新，允许更新标题。删除，允许删除数据库条目。这些目前工作正常。

我添加了一个名为Complete（completeBtn）的第三个按钮。当用户按下Complete按钮时，我希望EditText（titleText）更改为“Marked Complete”，并在数据库中更改标题条目。我认为我非常接近，但不确定问题是什么。

目前没有显示错误，但是当我按下“完成”按钮时，它不会将titleText的EditText更改为“标记为完成”或将存储在数据库中的标题值更改为“标记为完成”

任何帮助将不胜感激。：）

我认为您错过了匹配button点击实施

试试这个;

 @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_update:

                String title = titleText.getText().toString();
                String desc = descText.getText().toString();

                dbManager.update(_id, title, desc);
                this.returnHome();
                break;   //missing break statement

            case R.id.btn_complete:
                titleText.setText( "Marked Complete" + completeBtn.getText());
                complete();
                break;

            case R.id.btn_delete:
                dbManager.delete(_id);
                this.returnHome();
                break;
        }
    }

    public void complete(){
        String title = titleText.getText().toString();
        String desc = descText.getText().toString();

        dbManager.update(_id, title, desc);
    }
