Crash on ListView.removeFooterView(View)
How is it possible to get a null pointer exception when removing an footerview? I checked that both the footerview and listview are not null before calling
myListView.removeFooterView(mFooterView)
This listview does have a multi-list adapter. I also checked the parent of every footer that could have been added and the parent of each one was null.
BTW, where on earth is the getAllFooterViews? hasFooterView(footerView)? methods in the SDK.
PS. I don’t think a well written API should ever hide such information.
FATAL EXCEPTION: main
java.lang.NullPointerException
at android.widget.ListView.removeFooterView(ListView.java:461)
at com.mypackage.MyActivity.clearAllFooters()
It does not seem to matter which footer. Its really anything I try to remove at this point, any of the four footers that might have been added.
A bit of context, the ListView is not currently visible, does have focus, and the footer is being cleared after the return of an Async call. I have three listviews on the same MyActivity, and this ListView is not currently visible, it does not have the focus, but still a null pointer exception?
I am compiling 4.03 and deploying on android sdk 2.2
I am also checking that footer count is greater than 0.
It could be the version of your Android API. This is described very well here: Crash on ListView.removeFooterView(View)
It looks like the Android team may have forgotten to check for NULL in their API. You may be able to fix this in your custome Adapter class.
