我创建了AlertDialog一个AlertDialog.Builder并设置了一些项目setItems().显示对话框但我看不到任何项目.我所看到的只是信息.

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();

如果我设置了PositiveButton,我可以看到那个按钮就好了.我也试过设置MultiChoiceItems,SingleChoiceItems但这些都不起作用.
