I’ve gone deep enough into reading the Android documentation and in particular into saving View states. And the sources could not answer some of the questions.

1. Why do Views that work with text save this very text without having an id? The documentation clearly states that there should be an id, and this is logical, because when we receive data from the Bundle, we need to explicitly understand which widget they belong to.
2. For some reason, EditText saves the text, but TextView does not, just why? Does it depend on the type of TextLayout? I know it depends on the freezesText and the availability of the id. But EditText is able to save text without id. What is the reason for the different behavior between them and why the save behavior was not implemented in the TextView, which is the parent for EditText.

Moreover:

1. Why EditText or Button will not save text in the same way as TextView, and it should not save without an id.
2. I want to add that the documentation explicitly states that the View must have a unique id in the current view hierarchy tree. But if the EditText and TextView ids match, then when the configuration is changed, the text will be restored in both widgets. This once again confirms the recovery by id.

I want to point out that the essence of the issues is not the implementation of a more logical widget behavior. I am interested in the reasons for the presence of such widget behavior. Some logical reasoning that I can’t find and form myself.
