无法将int传递给setMessage（String）方法

Question

Why do I get compile error in this sentense?

this.message.setMessage(R.string.game_over);

Error messsage:

The method setMessage(String) in the type Messages is not applicable for the arguments (int)

I want to use string from my res which exist in string file. I know the arg is int but this is the way I read in sites

Answer 1

The int is a resourceID. You have to get the String the ID represents:

this.message.setMessage(getResources().getString(R.string.game_over));

Answer 2

The method setMessage expects to receive a String . However, you are sending it an integer.

More specifically, you are sending it the integer which is the resource key to a string. To get the string you want, you will need to do something like:

Context myContext = getApplicationContext();
this.message.setMessage(myContext.getString(R.string.game_over));
