I want to navigate items in a tree hierarchy.
I put the items on the same level in a listview. Upon clicking the item in the listview it will open another listview to show the items in the child level.
I want the user to navigate easily to another level (parent, grandparent, grandgrandparent) without pressing the back buttons several times.
What is the best way (what type of Android controls) to handle this? Examples provided will be great.
