AlertDialog的项目未显示 [英] AlertDialog's items not displayed

问题描述

我用AlertDialog.Builder创建一个AlertDialog，并用setItems()设置一些项目.显示对话框，但是我看不到任何项目.我所看到的只是消息.

I create an AlertDialog with an AlertDialog.Builder and set some items with setItems(). The dialog is shown but I cannot see any of the items. All I see is the message.

final CharSequence[] items = {"Red", "Green", "Blue"};

AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(activity);
dialogBuilder.setMessage("Pick a color");
dialogBuilder.setItems(items, new DialogInterface.OnClickListener() {        
    public void onClick(DialogInterface dialog, int which) {
        // Do anything you want here
    }    
});

dialogBuilder.create().show();

如果设置PositiveButton，则可以看到该按钮.我也尝试设置MultiChoiceItems和SingleChoiceItems，但是这些都不起作用.

If I set the PositiveButton, I can see that button just fine. I also tried setting MultiChoiceItems and SingleChoiceItems but neither of these work either.

推荐答案

使用setTitle而不是setMessage设置邮件正文并覆盖项目列表.

Use setTitle instead of setMessage which sets message body and overrides the items list.
