Android: inputType = "textCapWords" -- size of the first letter of a word

Android: inputType = "textCapSentences" -- only the size of the first letter

Android: inputType = "textAutoCorrect" -- the first two are automatically completed.

Android: inputType = "textAutoComplete" -- the first two are automatically completed.

The EditText component derives two subclasses:

AutoCompleteTextView: The EditText with auto-completion. Like the search bar of the browser, it must be used with the Adapter.

ExtractEditText: Not a UI component, it is the underlying service class of the EditText component and is responsible for providing full-screen input support.
