删除你的$sign。这是问题的根源，因为它不是一个数字。同时将变量类型更改为double。

删除$符号。这是问题的根源，因为它不是一个数字。同时将变量类型更改为double。

它第二次崩溃，因为$被添加到编辑文本值中，当您在该编辑文本上执行getString时，它将为您提供附加有$符号的字符串。第二次计算时，必须删除$symbol

根据您的代码显示一个值

String value=subtotal.getText().toString();
String replace=value.replace("$","");
Integer valuesubtotal = Integer.parseInt(replace);

它第二次崩溃，因为$被添加到编辑文本值中，当您对该编辑文本执行getString操作时，它将为您提供附加有$符号的字符串。第二次计算时，必须删除$symbol
根据您的代码显示一个值

String value=subtotal.getText().toString(); String replace=value.replace("$",""); Integer valuesubtotal = Integer.parseInt(replace);
在调用（textview/editText）.getText（）.toString（）之前，删除$symbol并使用double代替int
试试这个：

String total = "$10.5"; String strAmount = total.replace("$",""); double value = Double.valueOf(strAmount); Log.e("VALUE", String.valueOf(value));
