自定义布局访问activity

Question

在fragment中有自定义布局，extend RelativeLayout

public class Footer extends RelativeLayout

如何从这个自定义对象中使用getSupportFragmentManager？我用this.getContext()的时候会给出应用，不是 FragmentActivity

 The method getSupportFragmentManager() is undefined for the type Footer (extends RelativeLayout)

Answer 1

this.getactivity()获得父activity
