alertdialog显示checkboxes的有关问题

alertdialog显示checkboxes的问题

想在alertdialog上显示一个多个选项的对话框如下

public void showSettingsBox(){ 
  final CharSequence[] items = {"Item1", "Item2", "Item3"}; 
  final boolean checked[] = new boolean[]{false,false,false}; 
 
  AlertDialog.Builder builder = new AlertDialog.Builder(fLabyrinthGame);  
  builder.setMessage(fMessage) 
   .setCancelable(false) 
   .setMultiChoiceItems(items, checked, new OnMultiChoiceClickListener() { 
 
    @Override 
    public void onClick(DialogInterface dialog, int which, boolean isChecked) { 
     CharSequence text = "Item number " + which; 
     int duration = Toast.LENGTH_SHORT; 
 
     Toast toast = Toast.makeText(fLabyrinthGame, text, duration); 
     toast.show(); 
 
    } 
   }) 
   .setPositiveButton("Apply", new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int id) { 
     dialog.cancel(); 
    } 
   }); 
  builder.setTitle(fTitle);  
  builder.setIcon(R.drawable.icon_exclamation);  
 
  AlertDialog alert = builder.create();  
 
  alert.show();    
 } 
结果出现一个空白除了最后一个按钮

 

要想实现功能需要去掉setMessage(fMessage)，这是因为setMultiChoiceItems or setItems 是互相冲突的貌似
