Android, Listview Illegalstateexception: "The Content of the Adapter Has Changed But Listview Did Not Receive a Notification"

Android, ListView IllegalStateException: The content of the adapter has changed but ListView did not receive a notification

I had the same issue.

I was adding items to my ArrayList outside the UI thread.

Solution: I have done both, adding the items and called notifyDataSetChanged() in the UI thread.

The content of the adapter has changed but ListView did not receive a notification -Android

Try this :-

doInBackground(....) {
 mPseudoList.addAll(fetched_list);
 return xyz;
}

onPostExecute(...) {
 mAdapterList.addAll(mPseudoList);
 mAdapter.notifyDataSetChanged();
}

Change the adapter list reference in onPostExecute(...) and then notify the adapter !!

Note :-

In doInBackground dont update the list whose reference the adapter holds , instead use a pseudo-list and update the adapter reference list in onPostExecute

How to resolve The content of the adapter has changed but ListView did not receive a notification” exception

Fixed the error by adding

suggestionAdapter.notifyDataSetChanged();

on whenever the list is changed instead of calling it after a n number of insertions.

ListView IllegalStateException: “The content of the adapter has changed but ListView did not receive a notification”

First off, unless you "need" for your various bounded components to be made aware of the change in the adapter content on every iteration I would only call adapter.notifyDataSetChanged() after you've completed all the additions.

Secondly, can you provide the Exception and StackTrace?

Third, what Thread is this code being invoked with (the main GUI dispatching thread or a background)?

Thanks Migher for the updated Logcat. Do me a favor to help clarify a point: can you run a quick test to see what happens when you manually enter the same data values ... do it from a menu selection or a button click event (so we'll know it's on the GUI thread)? Getting the same error?

Also worth pointing out is give a SimpleCursorAdapter a try instead of the regular Adapter you're currently using. As I'm not able to run this through my debugger this might be just a simpler fix than going back and forth with "asynchronous tech support" suggestions, as I'm sure you'd like this fixed sooner rather than later.

Let me know how either of these work - thanks

IllegalStateException “The content of the adapter has changed but ListView did not receive a notification”

I have changed the method for filtration instead of writing

public void afterTextChanged(Editable s) {
    searchAdapter.getFilter().filter(s.toString());
    searchAdapter.notifyDataSetChanged();
    drugListView.requestLayout();       
}

I have changed it and start using FilterListener
and called notifyDataSetChanged in that method and now everything works like charm

java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification in android Studio

Its because you are changing the array used in adapter in background thread.
You are calling :

SearchItem.add(search);

in doInbackground method. Instead do this in onPostExecute method.

Not sure how to deal with ListView IllegalStateException: “The content of the adapter has changed but ListView did not receive a notification”

You have to notify the adapter whenever you do changes in the weatherArrayList.

For Example,

weatherAdapter.notifyDataSetChanged()

But in your case to use like that you have to declare the weatherAdapter as a property of the class.

I hope it will help you.

java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification - List with Universal Image Loader

try replacing the below line of code

 ((ListView) listView).setAdapter(new ImageAdapter());

with

 ((ListView) listView).setAdapter(mAdapter);

See that for the listView you are always setting a new adapter and in your onPostExecute you are notifying to a different instance of adapter
