AlertDialog当我添加消息时,有人知道为什么不显示项目列表.setMessage()吗？将显示负面和正面按钮,但不会显示列表.当我删除所有行的行.setMessage().

这是我的代码:

AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(this.getActivity());
myAlertDialog.setTitle("Options");
myAlertDialog.setMessage("Choose a color.");

CharSequence[] items = {"RED", "BLUE", "GREEN" };

myAlertDialog.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {
        // do stuff
    }
});

myAlertDialog.setNegativeButton("NO",new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {
       // do stuff
    }
});

myAlertDialog.setPositiveButton("YES",new DialogInterface.OnClickListener() {

    @Override
    public void onClick(DialogInterface dialog, int which) {
       // do stuff
    }
});

myAlertDialog.create();
myAlertDialog.show();
