How to solve the error like java.lang.Throwable: setStateLocked?

I am developing an app. In it I'm using a listview. When I click on list item, it should go to next activity, i.e ProfileActivity2.java. It works fine, but in this ProfileActivty2 there is a button at the bottom and when I click on this button my app gets crashed and stopped in listview page. And shows the error java.lang.Throwable: setStateLocked in listview layout file i.e At setContentView. How do I solve this error?
//ProfileActivity2.java

I think the error is at this line inside btn.setOnClickListener of getview block just use startActivity(intent);

how to display details of single item of list in another activity from url (json data)?

I have written a program to display the list of json data from a url which has an image and 5 textviews which is displaying perfectly.
Url : https://itunes.apple.com/search?term=jack+johnson&limit=50.
When i click on an item from the list i want to display the details of that item in another activity based on the track-id
Url : https://itunes.apple.com/lookup?id=659234741
So when i click on the item the details are getting displayed in the textview , but by default it is displaying the details of id = 659234741 for some items or in short the details does not match.
Need some help to figure out the problem

Thank you

The problem is that you are initializing the resultp each element in your getView method, so therefore the last id/element of the listview adapter's data will be considered as the resultp.
Im sure that the id 659234741 is the last element, which will always be the id for each onclick that would happen.
A solution for this is to create a final resultp within your getView method instead of having just one global resultp.
final HashMap<String, String> resultp = data.get(position);

ListView Doesn't display anymore than 8 ImageViews

I am decoding jpeg images from a server request I get using json. I display them with a custom ListView Adapter along with a little text.
The images display correctly for the first 8 ImageViews in the ListView, however, after that it will no longer display the image (it will display the text). For example, if I have a total of 10 images, the last two images will not show in the ListView, but if I delete the first 2 images, the last two will show, so there is no concern about retrieving the actual images.
On my main activity (NotesActivity) I have a button that goes to another activity which does an asyntask, and in that async task in the onPostExecute, it returns back to the main activity where it should show the updated list (and it does, unless there are more than 8 images).
I don't know where to begin, any suggestions?

"returnRes cannot be resolved to a variable" error in android

I had tested the function of endless Scrolling function in a dummy projects, it works fine but if i paste the same code in my original project m getting "loadMoreListItems cannot be resolved to a variable" on the variable "loadMoreListItems" and "returnRes cannot be resolved to a variable" on the variable, even i checked for android.R imports and layout name everything is correct dont know where is the mistake.

This has nothing to do with Android resources.
The variable loadMoreListItems is used in onCreate(), but it is defined in _loaddata(). You cannot define a variable in one method and use it in another method.
You could return loadMoreListItems from _loaddata()
private Runnable _loaddata() {
...
return loadMoreListItems;
}
and use it in onCreate() like
Runnable loadMoreListItems = _loaddata();
...
Thread thread = new Thread(null, loadMoreListItems);
And you use returnRes in Runnable loadMoreListItems before it is defined later in the same method. You must first define and initialize returnRes and then you can use it in loadMoreListItems. So moving returnRes before loadMoreListItems should solve this one.
