You need to convert your doubleto a Stringand then pass that Stringas an argument to the setText(String)method. This is how you convert a doubleto a String:
您需要将您的转换double为 a String，然后将其String作为参数传递给该setText(String)方法。这是将 a 转换double为 a 的方式String：
double d = 3.14;
String s = String.valueOf(d);
// s is now "3.14"
