Replacing a character by another character in a string in android?

Simply i want to replace a character with another in android.. My code:

et = (EditText) findViewById(R.id.editText1);
String str = et.getText().toString();
str.replace(' ','_');
et.setText(str);
System.out.println(str);

But here the "space" is not replaced by "underscore".. I also tried other character too..

please help!!

See code: 

et = (EditText) findViewById(R.id.editText1);
String str = et.getText().toString();
str = str.replace(' ', '_');
System.out.println(str);

String is immutable and you cannot change it. So, you need to do this:

str = str.replace(' ','_');

Strings are immutable in Java - replace doesn't change the existing string, it returns a new one. You want:

str = str.replace(' ','_');

(This is definitely a duplicate, but I don't have enough time right now to find an appropriate one...)
