    View rootView = inflater.inflate(R.layout.fragment_maintain, container, false);

    new JSONParse().execute();
    return rootView;


}


private class JSONParse extends AsyncTask<String, String, JSONObject> {
    private ProgressDialog pDialog;
    @Override

        pDialog.setCancelable(true);
        pDialog.show();
    }
    @Override

    }
    @Override

        pDialog.dismiss();
        try {
            // Getting JSON Array from URL
            maintenance = json.getJSONArray(TAG_OS);
            for(int i = 0; i < maintenance.length(); i++){
                JSONObject c = maintenance.getJSONObject(i);
                // Storing  JSON item in a Variable
                String mid = c.getString(TAG_MID);

                String note = c.getString(TAG_NOTE);
                // Adding value HashMap key => value
                HashMap<String, String> map = new HashMap<String, String>();
                map.put(TAG_MID, mid);
                map.put(TAG_PID, pid);
                map.put(TAG_STATUS, status);
                map.put(TAG_DESCRIPTION, description);
                map.put(TAG_NOTE, note);
                oslist.add(map);
                list=(ListView) getActivity().findViewById(R.id.list);
                ListAdapter adapter = new SimpleAdapter(getActivity(), oslist,
                        R.layout.list_maintain,
                        new String[] { TAG_MID,TAG_PID, TAG_STATUS, TAG_NOTE}, new int[] {
                        R.id.mid,R.id.pid, R.id.status, R.id.description, R.id.note});
                list.setAdapter(adapter);
                list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View view,
                                            int position, long id) {
                        Toast.makeText(getActivity(), "You Clicked at " + oslist.get(+position).get("pid"), Toast.LENGTH_SHORT).show();
                    }
                });
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}

}

Look at your Adapter instantiation. The arrays for the data keys and the View IDs are different sizes. — Mike M.

What is +position in oslist.get(+position).get("pid"); ? and ur String[] and int[] is not matching — Harsha Vardhan

FragmentMaintain is not listed in your stack trace. You need to post the code that causing the problem. — jww

If the length is 4, max index should be 3 as the index starts from 0.

Try this way,hope this will help you to solve your problem.

ListAdapter adapter = new SimpleAdapter(getActivity(), oslist,R.layout.list_maintain,new String[] {TAG_MID,TAG_PID,TAG_STATUS,TAG_DESCRIPTION,TAG_NOTE}, new int[] { R.id.mid,R.id.pid, R.id.status, R.id.description, R.id.note});

You are missing to pass TAG_DESCRIPTION in String Array at adapter initialization.

When you create SimpleAdapter the 4th and 5th arguments need to be same size.

So strings of 4th argument will be used as keys to fill view with value of the map which is 3rd argument of constructor.

And the way matching a view with a key is specifying them in 4th and 5th arguments which are containing keys and containing ids of views respectively, to have same index in each array.
