import android.widget.EditText;

CodePudding user response：

What happened in the IDE is that when you did not IMPORT a class (eg: EditText), the IDE will not recognise your UI element (EditText) as anything.

What you have to do is just IMPORT the (EditText) class:

Add this before your CLASS declaration:
import android.widget.EditText

Move your cursor to EditText and then do Alt Enter

Since you said you are a beginner (for now), just know that for every UI element you'll have to do that
