Question

The question i have is a bit difficult to explain so please bear with me,
I have implemented actionBar for an app, the thing is i have 5-6 menu items on the actionBar and handling the click event using

onOptionsItemSelected(MenuItem item)

what happens is each menu item click inflates a particular view in a common region[i.e the inflated views overlap each other,not a common container],
i need to remove that view and inflate another one if another item is clicked,and i achieve this using simple if comparison statements.

While the solution is simple,implementing it and checking for so many conditions makes it complex and the code unreadable.

I just want to know if there exists a more elegant solution for this problem?

Answer 1

Keep a reference to the last inflated view:

private View lastInflatedView;

in the onOptionsItemSelected method hide the view with this reference and set it to the next inflated.

if (lastInflatedView != null) {
 lastInflatedView.setVisibility(View.GONE);
}

View newView = //inflate here
lastInflatedView = newView;
