Difference between R.string.xxx and getString(R.string.xxx)?

Issue

What is the difference between two ways to obtain a string from resources:

setPositiveButton(R.string.some_string);

OR

setPositiveButton((getString(R.string.some_string));

?

In both cases I get the same result.

Solution

R.string.some_string

is a public final static int that is a fixed ID to a specific String in your R.java file. This is generated automatically.

getString(R.string.some_string)

returns the String referenced by the above by reading the R.java file.

It depends on the implementation of

setPositiveButton(String)

and

setPositiveButton(int)

what difference internally is made, like with error checks.
