公共类MainActivity扩展了Activity {

private AutoCompleteTextView act;
private MultiAutoCompleteTextView mact;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    String[] countries=getResources().getStringArray(R.array.list_of_countries);

    ArrayAdapter<String> adapter =new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,countries);

    act=(AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);
    mact=(MultiAutoCompleteTextView)findViewById(R.id.multiAutoCompleteTextView1);

    act.setAdapter(adapter);
    mact.setAdapter(adapter);
    //******************************************************************
    mact.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
