Android：找不到资源异常

时间：2015-02-10 05:46:43

标签： java android runtime-error

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

分配：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，预付金额和利率。根据这些值，应用程序应计算贷款金额并显示10年，20年和30年贷款的每月付款。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。

我只将这些数字分成几年开始，并没有实现兴趣。目前它只是输入和存储的东西。但这不是问题。当我尝试更改第一个编辑文本时，会出现此错误消息。

我在你的代码中看到一个错误..

请使用此行

customYearView.setText(""+currentCustomYear);

而不是

customYearView.setText(currentCustomYear);

由于TextView接受字符串值。

编译完代码后，我发现了行中的错误

<强> customYearView.setText（currentCustomYear）;

其中currentCustomYear是整数值。

将您的方法更新为以下

private void updateCustom() {

        moneyRemain = purchaseGiven - downGiven;

        customYearView.setText(""+ currentCustomYear);

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

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)

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