我正在创建一个AlertDialog.如果像这样创建它:

AlertDialog.Builder builder = AlertDialog.Builder((RelationActivity)getContext());
builder.setMessage("No relations found.");
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {       
    public void onClick(DialogInterface dialog, int id) {
        ((RelationActivity)getContext()).finish();
    }
});
builder.create();
builder.show();

结果如下:http://www.ozze.com.br/1.png

但是,如果我尝试设置主题,像这样:

AlertDialog.Builder builder = new AlertDialog.Builder(((RelationActivity)getContext()), android.R.style.Theme_Holo_Light_Dialog);

结果如下:http://www.ozze.com.br/2.png

拜托,有人可以帮我解决这个问题吗？看起来在使用主题时,主题"围绕"警报对话框.

我在 MacOS 上使用 NetBeans 来开发使用 PI4J 的应用程序。一切看起来都不错，但我收到以下错误，指出 PI4J 无法加载。有谁知道如何解决这个问题？
