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

Sorry for a brick of a code but I read that I need to run something on UI thread, how do I do that? private ArrayList JsonFIveDays(String weatherSearchResults) is where I set my listview adapter if that helps.

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.

You need to notify adapter that you changed data with notifyDataSetChanged(). You can do that in setData method after changing data.

When creating the adapter, send your Activity as context.
Then
adapter(Activity context);
..
context.getIntent();

I found this useful code of RecyclerView. Might it will help others. It is complete working example.

Call notifyDataSetChanged() on your adapter

Here is a demo for how u can do that http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/

USE setListAdapter(yourAdapter);
Make your adapter to ListAdapter find more details here
then just use
yourAdapter.notifyDataSetChanged(); and you are done !

1) create a method
2) set adapterView in that method.
3) at click event of any image button call that method.
or to put Adapter.notifyDataSetChanged();
I think this would be easy for you.

Also you can do this like...
I have custom row for list. It has textview and I can change it's value ...
((TextView)(myWatchList.getChildAt(INDEX - myWatchList.getFirstVisiblePosition()).findViewById(R.id.symbolCountTV))).setText(NEWSTRING);
