How do I convert from int to String? (20 answers)

Closed 5 years ago.

我有一丝不.的变数,当我把这一变数作为昂儒昂文案文时,它可能会留下一个错误,因为它带有印章。我已经检查了,但找不到固定功能。因此,我如何能够这样做?

int sdRate=5;
//text_Rate is a TextView
text_Rate.setText(sdRate); //gives error

Answer 1

Use :

int sdRate=5;
//text_Rate is a TextView
text_Rate.setText(String.valueOf(sdRate)); //no more errors

Answer 2

int sdRate=5;
text_Rate.setText(Integer.toString(sdRate));

Answer 3

你们可以使用

text_Rate.setText(""+sdRate);

Answer 4

你试图:

text_Rate.setText(String.valueOf(sdRate));

Answer 5

你有两种选择:

int sdRate=5;
text_Rate.setText(String.valueOf(sdRate));  //faster!, recommended! :)

(2) 增加空洞:

int sdRate=5;
text_Rate.setText("" + sdRate));

Casting is not an option, will throw a ClassCastException

int sdRate=5;
text_Rate.setText(String.valueOf((String)sdRate)); //EXCEPTION!

Answer 6

或许你会这样做。

int sdRate=5;
//text_Rate is a TextView
text_Rate.setText(sdRate+""); //gives error
