Why EditText in a custom compound view is re-using the text entered in another compound view instance?

Question

I\'m trying to write a custom compound view composed by a TextView and an EditText, _compound_view.xml_:

Answer 1

The issue is happening because of the id field on compound_view.xml
From your code, I just noticed that you inflated compound_view layout file in CompoundView class.

As soon as you create compound_view.xml and put android:id="@+id/textLabel" and android:id="@+id/textEdit" id in your layout xml file, android studio automatically create those ids into int values in R class for single time.

So, when you put CompoundView twice time in your activity_main.xml layout file, you just creating two instance of CompoundView but, both instances textEdit and textLabel have only 1 address location for each one. So, they are pointing to same address locations which are declared in R class.

That's why, whenever you change textEdit or textLabel text programatically, they also change other textEdit or textLabel which are presented in both of your CompoundView
