[英]App is crashing, I know it has something to do with “java.lang.NumberFormatException: Invalid int: ”$19.00“”(in log), but I dont know how to fix it
Its basically a calculator app. 它基本上是一个计算器应用程序。 The problem occurs when the user goes back to edit the edittexts that they previously edited, and clicks the calculate button for the second time. 当用户返回以编辑他们先前编辑的编辑文本,然后第二次单击“计算”按钮时,就会出现此问题。 I understand the answer is smack in my face but I really know very little about this so I cant find the solution. 我知道答案是一击,但我对此实在知之甚少,所以找不到解决方案。 I have been stuck for 2 weeks. 我被困了两个星期。 Thank you for your help in advance, I know this is a terrible question but I am really stuck. 谢谢您的事先帮助,我知道这是一个可怕的问题,但我真的很困惑。 Replacement code is much appreciated as I am a novice! 我是新手,非常感谢替换代码!

Remove your $ sign. 删除您的$符号。 It is causing the issue since it is not a number. 因为不是数字,所以引起了问题。 Also change your variable type to double. 同时将变量类型更改为double。
Before call (textview/editText).getText().toString(), remove the $ symbol and use double instead int. 在调用(textview / editText).getText()。toString()之前,删除$符号并使用double代替int。
Try this: 尝试这个:
String total = "$10.5";
String strAmount = total.replace("$","");
double value = Double.valueOf(strAmount);
Log.e("VALUE", String.valueOf(value));
Example: 例:
public void calculate2() {
//get entered texts from the edittexts,and convert to integers.
Double value1 = moneyToDouble(sand1.getText().toString());
Double value2 = moneyToDouble(sand2.getText().toString());
Double value3 = moneyToDouble(sand3.getText().toString());
Double value4 = moneyToDouble(sand4.getText().toString());
Double value5 = moneyToDouble(sand5.getText().toString());
Double value6 = moneyToDouble(sand6.getText().toString());
Double value7 = moneyToDouble(sand7.getText().toString());
Double value8 = moneyToDouble(extra1.getText().toString());
Double value9 = moneyToDouble(extra2.getText().toString());
Double value10 = moneyToDouble(extra3.getText().toString());
Double value11 = moneyToDouble(extra4.getText().toString());
Double value12 = moneyToDouble(extra5.getText().toString());
Double value13 = moneyToDouble(extra6.getText().toString());
Double valuesubtotal = moneyToDouble(subtotal.getText().toString());
Double valuetotal = moneyToDouble(total.getText().toString());
//do the calculation
Double calculatedValue1 = (9.5*value1);
Double calculatedValue2 = (9.5*value2);
Double calculatedValue3 = (9.5*value3);
Double calculatedValue4 = (9.5*value4);
Double calculatedValue5 = (9.5*value5);
Double calculatedValue6 = (9.5*value6);
Double calculatedValue7 = (9.5*value7);
Double calculatedValue8 = (2.25*value8);
Double calculatedValue9=(1.5*value9) ;
Double calculatedValue10=(3.5*value10) ;
Double calculatedValue11 =(3.95*value11) ;
Double calculatedValue12 = (3.5*value12);
Double calculatedValue13 = (2.95*value13);
Double calculatedsubtotal = (d+calculatedValue1+calculatedValue2+calculatedValue3+calculatedValue4+calculatedValue5+calculatedValue6+calculatedValue7+calculatedValue8+calculatedValue9+calculatedValue10+calculatedValue11+calculatedValue12+calculatedValue13);
Double calculatedtotal = ((.1*calculatedsubtotal)+calculatedsubtotal);
//set the value to the textview, to display on screen.
result1.setText("$"+String.format( "%.2f", calculatedValue1 ));
result2.setText("$"+ String.format( "%.2f", calculatedValue2 ));
result3.setText("$"+ String.format( "%.2f", calculatedValue3 ));
result4.setText("$"+ String.format( "%.2f", calculatedValue4 ));

It is crashing second time because $ gets added to your edit text value and when you do getString on that edittext it will give you string appended with $ symbol. 这是第二次崩溃, 因为$被添加到您的编辑文本值中,并且当您在该edittext上执行getString时,它将为您提供带$符号附加的字符串。 You have to remove $ symbol when you do calculation second time 第二次计算时必须删除$符号
Showing you for one value according to your code 根据您的代码向您显示一个值
String value=subtotal.getText().toString();
String replace=value.replace("$","");
Integer valuesubtotal = Integer.parseInt(replace);
