i'm new with Android and i'm writing a simple alarm clock application.when i type the string into the EditText like this "10:00,Monday" this string will compare syntax with the defined string if true it'll turn on the AlarmClock. But i don't know how to compare. May you give me an idea? Thanks so much. My app's interface and code below
