java - 复利计划不会计算

转载作者：行者123 更新时间：2023-12-01 15:05:46

我一直在尝试让这个程序运行，但由于某种原因它不会计算复利。如果有一点帮助，我们将不胜感激。请注意，对于输入到compoundInterestEditText 字段中的任何值，我都没有完成if 语句。我希望它能与我所拥有的一起工作。 endValueEditText 甚至不会更新。

最佳答案

我猜您会收到堆栈溢出异常，因为 setText() 调用 onTextChanged() ，而 onTextChanged() 又调用 updateValues() ，而调用setText()，它调用...(一遍又一遍)。只需向您的 TextWatcher 添加一个 boolean 值即可:

private TextWatcher endValueEditTextWatcher = new TextWatcher() {
    boolean update = false;
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        update = !update;
        if(!update)
            return;

        ...
    }
}

<小时/>

但我认为您创建了一个奇怪的用户界面:只有当用户在 endValueEditText 中键入一个值时，updateValues() 才会运行。我认为您应该创建一个标记为“计算兴趣”的按钮，并读取该按钮的 OnClickListener 中的 EditText 值。您还应该将 endValueEditText 更改为 TextView，因为用户调用确实会更改此值。
