Populating a ListView with parse.com

I'm building an app that would display the the values from column "NameMessage" from the table/class "messages" from my parse.com app called : "ParseQueryAdapter" on the click of "Display" button. Nothing happens when display button is clicked, and the app crashes when the display button is clicked the 2nd time. I'm also attaching the logcat. Please help. Thanks

        populatelist();
        }
        }

protected void populatelist() {
lv = (ListView) findViewById(R.id.myList);
ParseQuery<ParseObject> query = ParseQuery.getQuery("Messages");
query.findInBackground(new FindCallback<ParseObject>(){

    @Override
    public void done(List<ParseObject> NameMessage, ParseException e) {
        if (e == null){
            for(int i = 0;i<NameMessage.size();i++){

                messagesarray.add(NameMessage.get(i).toString());




            }

        }
        else {Log.d("Messages","Error:"+e.getMessage());}

    }


    });

ListView list = (ListView) findViewById(R.id.myList);
        lv.setAdapter(new ArrayAdapter<String>(MainActivity.this,R.id.myList,R.layout.list_item,messagesarray));    
}

}
