@SuppressWarnings("deprecation")
@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Uri allContacts= Uri.parse("content://contacts/people");
    Cursor c=managedQuery(allContacts,null,null,null,null);

    String[] columns=new String[]{
            ContactsContract.Contacts.DISPLAY_NAME,ContactsContract.Contacts._ID};
    int[] views=new int[]{R.id.ContactsName,R.id.ContactsID};
    SimpleCursorAdapter adaptor=new SimpleCursorAdapter(this,R.layout.activity_main,c,columns,views);
    ListView listView=(ListView)findViewById(R.id.ListView);
    listView.setAdapter(adaptor);
