Question

Parameters:

key a string

return:

an int value

but i can't get it that what it exactly return.

the ID of key that is in R.java or no something else???

Answer 1

It returns whatever you've put in that bundle with the same key.

Bundle bundle = new Bundle();
bundle.putInt("KEY", 1);
int value = bundle.getInt("KEY"); // returns 1

It's simply a map/dictionary datatype where you map a string value with something else. If you have other datatypes, you should use the appropriate put/get-methods for that datatype.
