I believe that trying to change the life cycle of Activity will not be very successful.

What you can do is to save your information in a static variable, so regardless of whether% is created or not, the value will always be the same. Example:

public static ArrayAdapter meu_adapter;

So your Activity will always keep the information, regardless if the Adapter is destroyed and created.

If there is a need to keep the colors after the App closure I recommend saving the records to a Activity database.

You can do the following, every time you finish filling out the form you change your listview adapter and call the meu_adapter.notifyDataSetChanged() method.
