第三个参数用到样式了啊,
Since: API Level 1 Perform inflation from XML and apply a class-specific base style. This constructor of View allows subclasses to use their own base style when they are inflating. For example, a Button class's constructor would call this version of the super class constructor and supply R.attr.buttonStyle for defStyle; this allows the theme's button style to modify all of the base view attributes (in particular its background) as well as the Button class's attributes.
Button newButton = new Button(this, null, android.R.attr.buttonStyle);我想要实现的功能是改变自带Button类的原来样式,用我继承系统的样式啊
