Question

我想以编程方式设置按钮样式。这意味着无需定义xml文件。我认为通过使用预定义的样式ID设置按钮的后台资源，我可以这样做。

失败的代码行是：

b1.setBackgroundResource(android.R.style.Widget_DeviceDefault_Light_Button_Borderless_Small);

状态

有一个例外

android.content.res.Resources$NotFoundException: Resource ID #0x1030179.

我做错了什么？

编辑：

我试过这个：

Button b = new Button(context,null,android.R.style.Widget_DeviceDefault_Button_Borderless);

这不再抛出异常，但按钮没有应用真正的样式。只有文字，按下它时没有不同的状态。

EDIT2：

按要求添加原始堆栈跟踪：
