To compare two strings, use String.equals

string1.equals(string2);

However, keep in mind you'll need to do a null check on string1 first else you may end up with a NullPointerException. A null-safe version could look like:

boolean match = (string1 == null ? string2 == null : string1.equals(string2));

One more Android-specific alternative is:

TextUtils.equals(string1, string2);
