Android：找不到资源异常

【问题标题】：Android: Resources Not Found ExceptionAndroid：找不到资源异常
【发布时间】：2015-02-10 05:46:42
【问题描述】：

我是 Android 开发的完全新手，并且已经上课三周了。该程序编译并运行得很好，直到我尝试更改任何 EditText 或滑动 seekBar。

作业：创建一个抵押贷款计算器应用程序，允许用户输入购买价格、首付金额和利率。基于这些值，应用程序应计算贷款金额并显示 10 年、20 年和 30 年贷款的每月还款额。允许用户使用 SeekBar 选择自定义贷款期限（以年为单位）并显示该自定义贷款期限的每月付款。

我一开始只有数字分年，没有执行利息。目前，它只是被输入和存储的东西。但这不是问题。当我尝试更改第一个编辑文本时出现此错误消息。

我花了几个小时试图自己修复它并寻找解决方案。我不知道我是否一直在寻找错误的地方或什么，但我已经走到了尽头。

感谢您提供的任何帮助。如果需要更多信息，请尽管询问。

编辑：添加完整的错误消息。

【问题讨论】：

  • 呃哦——你是不是直接复制了xml文件而没有做任何修改？如果是这样，您必须在第 20 行删除 //row 9。
  • 请将问题edit 发送至：请包含完整的错误消息。鉴于错误消息列出了行号，请确保您提供的代码与您从中获取错误消息的代码完全匹配。它目前与错误文本中的行号不匹配。
  • 我认为@Vivek 的回答会解决你的问题..

【解决方案1】：

我发现您的代码中有一个错误..

请使用这条线

customYearView.setText(""+currentCustomYear);

而不是这个

customYearView.setText(currentCustomYear);

由于 TextView 接受 String 值。

【讨论】：

    【解决方案2】：

    编译你的代码后，我发现了行中的错误

    customYearView.setText(currentCustomYear);

    currentCustomYear 是整数值。

    将你的方法更新到下面

    private void updateCustom() {

        moneyRemain = purchaseGiven - downGiven;
        
        customYearView.setText(""+ currentCustomYear);

        customYearResult.setText(String.format("%.02f", moneyRemain
                / currentCustomYear));
    }

    您崩溃的原因是您在 TextView 上设置了一个整数值，但 textview 只接受字符序列

    来自 Android 文档

    public final void setText (CharSequence text)

    更多信息请见here

    【讨论】：

      【解决方案3】：

      使用 customYearView.setText(String.valueOf(currentCustomYear));

      【讨论】：

      • 请编辑更多信息。不建议使用纯代码和“试试这个”的答案，因为它们不包含可搜索的内容，也没有解释为什么有人应该“试试这个”。
