AlertDialog不显示ListAdapter隐藏选项中的项目

Question

当我尝试使用ArrayAdaptor设置警报以显示一组项目时,将显示列表,但项目的字符不可见.如果选择了该项,则字符可见.抓住我的头脑为什么.感谢任何建议.下面是模拟器的代码和屏幕截图.

public class MessageTest extends Activity implements 
View.OnClickListener { 
        public final static String debugTag = "MessageDemo::"; 
        Button alert; 
        Button toast; 
        String[] items={"item1", "item2", "item3", "item4", "item5" }; 


        @Override 
        public void onCreate(Bundle icicle) { 
                super.onCreate(icicle); 


                setContentView(R.layout.message); 


                alert=(Button)findViewById(R.id.alert); 
                alert.setOnClickListener(this); 
        } 


        public void onClick(View view) { 
                if (view==alert) { 
                        ArrayAdapter<String> aa = new ArrayAdapter<String>(this, 
                                        android.R.layout.simple_list_item_single_choice, items); 


                        new AlertDialog.Builder(this) 
                                .setTitle("MessageTest") 
                                .setSingleChoiceItems(aa, 0, new DialogInterface.OnClickListener() 
{ 
                                        public void onClick(DialogInterface dlg, int which) { 
                                             Log.d(MessageDemo.debugTag, 
"DialogInterface.OnClickListener::onClick() is called -> which = 
"+which); 
                                        } 
                                }) 
                                .setIcon(android.R.drawable.ic_dialog_alert) 
                                .setPositiveButton("OK", new DialogInterface.OnClickListener() { 
                                        public void onClick(DialogInterface dlg, int sumthin) { 
                                             Log.d(MessageDemo.debugTag, "OK button is clicked -> sumthin 
= "+sumthin); 
                                        } 
                                }) 
                                .setNeutralButton("Close", new DialogInterface.OnClickListener() { 
                                        public void onClick(DialogInterface dlg, int sumthin) { 
                                             Log.d(MessageDemo.debugTag, "Close button is clicked -> 
sumthin = "+sumthin); 
                                                // do nothing -- it will close on its own 
                                        } 
                                }) 
                                .setNegativeButton("Cancel", new DialogInterface.OnClickListener() 
{ 
                                        public void onClick(DialogInterface dlg, int sumthin) { 
                                             Log.d(MessageDemo.debugTag, "Cancel button is clicked -> 
sumthin = "+sumthin); 
                                        } 
                                }) 
                                .show(); 
                } 
        }

我知道我回答的时间有点迟了,但我遇到了同样的问题,我只是通过改变来修复它

ArrayAdapter<String> aa = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_single_choice, items);

至

ArrayAdapter<String> aa = new ArrayAdapter<String>(this, android.R.layout.select_dialog_singlechoice, items);

我希望它对某人有帮助.
