In this video we will learn, how to use AutoCompleteTextView, which is a subclass of EditText and can show auto-complete suggestions when the user types something into the text input field.
We populate our suggestions popup with an ArrayAdapter to which we pass a string array. We will also change the comletionThreshold to change the number of characters the user has to type in to start getting suggestions. To customize it further we will also set a completionHint, change the popupBackground color and pass our very own layout for the dropdown list.
