    Spinner Sourcespinner;// = new Spinner(this);
    Sourcespinner = (Spinner)findViewById(R.id.Spinner1);
    ArrayAdapter<String> SourceArrayAdapter = new ArrayAdapter<String>(this,
     android.R.layout.simple_spinner_item,SourceArray);
    SourceArrayAdapter.add("Chennai");
    SourceArrayAdapter.add("Mumbai");
    SourceArrayAdapter.add("Kolkatta");
    SourceArrayAdapter.add("Delhi");
    Sourcespinner.setAdapter(SourceArrayAdapter);`

Try to add data to the ArrayList and just use the Collections class to sort for you:

Collections.sort(SourceArray);

If you need to add your own objects they need to implement the Comparable interface and implement the method compareTo(). When changing the ArrayList's data make sure to notify the adapter that new data might have been added by using this code:

SourceArrayAdapter.notifyDataSetChanged();
