AutoCompleteTextView和MultiAutoCompleteTextView

在android中我们可以使用AutoCompleteTextView来实现自动提示功能。
我们将需要进行提示的数据放入AdapterArray中，然后用AutoCompleteTextView的setAdapter方法，就可以让AutoCompleteTextView具有自动完成提示的功能了.

private static final String[] autoStr = { "a", "abc", "abcd", "abcde" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, autoStr);
    AutoCompleteTextView myAutoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.myAutoCompleteTextView);
    myAutoCompleteTextView.setAdapter(adapter);

private static final String[] autoStr = { "a", "abc", "abcd", "abcde" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, autoStr);
    AutoCompleteTextView myAutoCompleteTextView = (AutoCompleteTextView)findViewById(R.id.myAutoCompleteTextView);
    myAutoCompleteTextView.setAdapter(adapter);

MultiAutoCompleteTextView也是具有自动完成提示的功能，它和AutoCompleteTextView的区别就是MultiAutoCompleteTextView可以在输入框中一直增加新的选取值。编写方式也有所不同，在进行setAdapter之后还需要调用setTokenizer(),否则会出现错误

MultiAutoCompleteTextView autoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.myAutoCompleteTextView);
autoCompleteTextView.setAdapter(adapter);
autoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
