android - Wrong fragment in ViewPager receives onContextItemSelected call

Question

I have an app that shows a few fragments (of the same type) in a ViewPager and I'm having some trouble with context menu items. (I'm using the support library).

When a context menu item is selected in the context menu in one of the fragments, the wrong fragment is receiving the onContextItemSelected event call.

For example, if I'm on fragment #3 in the pager, the fragment at position #2 receives it instead. If I swipe back to fragment #2, fragment #3 receives the call instead.

I've got a sample here.

(I'm currently working around this in my own app by having a mHandleContext variable in each fragment and enabling/disabling it when the page is changed. That way the onContextItemSelected call will go out to all the fragments until the right one is called.)

Am I doing something wrong or is this a bug with the support library? As a side note, this didn't happen when I was using ActionBarSherlock 3.5.1, which had its own fork of the support library.

Answer 1

So this is some sort of idiotic design decision by Google or something that has just gone totally unconsidered. The simplest way to work around this is to wrap the onContextItemSelected call with an if statement like this:

if (getUserVisibleHint()) {
    // Handle menu events and return true
} else
    return false; // Pass the event to the next fragment

The compatibility library in ActionBarSherlock 3.5 had a hack like this.
