ResivedSMS.java:50 is:

listFragment = (ListView) inflater.inflate(
R.layout.list_fragment, container, false);


Whats my code problem and how to resolved Thanks?

Answer

problem:

inflater.inflate(R.layout.list_fragment, container, false);

You are inflating a LinearLayout not a ListView thus giving you ClassCastException

solution:

Since you are using ListFragment you can directly set the adapter, since ListFragment has its own default ListView. Set the adapter in the onCreate Method.

sample:

 @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ViewResivedSMSDetailes customListView = new ViewResivedSMSDetailes(getActivity(),testArray1,testArray2);
        setListAdapter( customListView ); //call the method if listFragment

    }
