Apps Has Stopped,while Click The Item In An Listview In The Second Time

Error showing in logcat java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter i

Solution 1:

I think that problem is that your are updating your Adapter ouside of UI Thread and it caused your Exception.

I guess that you need to make sure that you are manipulating with UI elements only from UI Thread. And if you are using AsyncTask so you need to call

adapter.notifyDataSetChanged();

in onProgressUpdate() or onPostExecute() method

Solution 2:

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

This issue means that the data that your basicAdapter is trying to adapt for the listView was changed, obviously means your itemDetailsrrayList doesn't contain the same data.

I suppose that you are manipulating this list in your activities.

That's normal to happen, and what you should do, is to notify the adapter by calling adapter.notifyDataSetChanged() in onResume callback of the activity using the adapter.

Solution 3:

This is the correct code i got ItemListAdapter.java

publicsynchronizedvoidrefreshAdapter(ArrayList<Recipedetails> items){
    //itemDetailsrrayList.clear();
    itemDetailsrrayList = items;
   notifyDataSetChanged();
}

and in mylistviewactivity.java

privatevoidrefreshYourAdapter(final ArrayList<Recipedetails> items){

//this is what I meant. The error clearly states you are not updating the adapter on the UI thread runOnUiThread(new Runnable() { public void run() { _itemListAdapter.refreshAdapter(items); } }); } and

@Override

protected void onResume() { super.onResume(); _itemListAdapter = new ItemListBaseAdapter(this, image_details); refreshYourAdapter(GetSearchResults()); lv1.setAdapter(_itemListAdapter);

} we have to add these things in your listview activity it will works very fine and remove static in idemlistadapter
