Question

自动完成文本视图在Android 2.3版中无效

我正在开发一个应用程序，其中我使用自动完整文本视图

使用Android 4.0进行测试时，自动完成功能正常

但是当我使用Android 2.3时，自动完成下拉菜单没有显示输入任何文本的内容也不可见

我的代码如下：

在onCreate

ArrayAdapter<String> adapter = new ArrayAdapter<String>
                      (this,android.R.layout.simple_list_item_1, itemClass);
className.setAdapter(adapter);
className.setThreshold(1);

    public class Autocomplete extends Activity {
        /** Called when the activity is first created. */
        String[] names =

        };
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
           ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,names);
            MultiAutoCompleteTextView textView = (MultiAutoCompleteTextView) findViewById(R.id.books);
            //AutoCompleteTextView acTextView = (AutoCompleteTextView)findViewById(R.id.books);
            //textView.setThreshold(1);
            textView.setAdapter(adapter);
            textView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
            //acTextView.setAdapter(adapter);
