hope this helps.

SharedPreferences.Editor edit = PreferenceManager.getDefaultSharedPreferences(this).edit();
    for (int i = 0 ; i < items.size(); i++) {
        ListViewItem item = items.get(i);
        edit.putString(Integer.toString(i), item.elementOne + "," + item.elementTwo + "," + item.elementthree);
    }
    edit.commit();

Write this code on your button's click

try {
        File myFile = new File("/sdcard/mysdfile.txt");
        myFile.createNewFile();
        FileOutputStream fOut = new FileOutputStream(myFile);
        OutputStreamWriter myOutWriter =
                new OutputStreamWriter(fOut);
        for (int i = 0; i < city.length; i++) {
            myOutWriter.append(city[i] +"\n");    
        }

        myOutWriter.close();
        fOut.close();
        Toast.makeText(getBaseContext(),
                "Done writing SD 'mysdfile.txt'",
                Toast.LENGTH_SHORT).show();
    } catch (Exception e) {
        Toast.makeText(getBaseContext(), e.getMessage(),
                Toast.LENGTH_SHORT).show();
    }
