问题 I have a number of custom objects that are significantly different from each other. These objects are stored in different lists and are to be displayed in different ListViews. Because of the design of these ListViews, I need to create my own custom ArrayAdapter. The thing is, the ListView design is supposed to be the same for all ListViews regardless of the objects in the list. To accomplish this I created an ArrayAdapter for every type of object.

The problem I am having is when the user selects a product from the list, and then presses back, it comes up with the list again instead of returning to the EditText activity.
