Java 再次单击按钮时出错简单的if-then-else语句（第一次正常工作）

我不熟悉android和java， 下面是一个简单的代码，比较我从编辑文本类型编号中获得的值，并将其与假设14000的值进行比较，但当我运行此应用程序时，如果条件为真，则其崩溃，即final_salary>14000如果为真，则其未将textview tv更新为r1值14000，应用程序崩溃，

还有一个请求，如果有人能指导我如何调试这个或捕捉这个错误点以使其正确，我来自VB平台，调试相对来说，我个人的意见是容易的，然后eclipse

Following is the dump from log cat ?

要将整数设置为TextView的文本。但由于存在一个方法TextView.setTextint ResourceId，编译器认为您正在使用这个方法，因为您的参数是整数。当框架尝试查找此StringResource时，它失败并引发异常。使用tv.setTextr1+或tv.setTextString.vlaueOfr1；。两者都将整数转换为字符串，但我建议使用第二个，因为第一个是一种不好的做法
