在自定义视图中访问片段引用

我有一个场景,片段在其布局中有自定义视图(通过扩展View类).自定义视图必须访问片段的某些方法.但是我无法在自定义视图中获得片段引用.此外,我无法从自定义视图(这是片段的子级)访问片段的任何方式

根据android片段:我们在视图的构造函数中获取上下文.此上下文是活动的实例.但是没有办法获得托管customview的片段的引用.

请让我知道如何访问自定义视图中的片段.

添加代码以更好地理解我的问题:

MyFragment .java

公共类MyFragment扩展Fragment {

int selectedOptionIndex;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
//get value of selectedOptionIndex from bundle and save it to this.selectedOptionIndex;

}

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
this.activity = activity;

}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.myFragmentview, container, false);
    return view;

//i can access views from fragment, but not vice versa. }

}

myFragmentview.xml

公共类CustomView扩展View {

private MyActivity context; 

/** Default Constructor */
public EasCalWeekViewHeader1(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
        this.context = (MyActivity) context;

// Now using context, we can access activity insatnce inside this customView and can call any method of activity instance. //But we cannot do this for fragments. There is not way to access parent fragment at this point. I cannot access selectedOptionIndex and use it to set in this view. //if view can access the parent activty, then it should also have an access to parent fragment.
}

/** Default Constructor */
public EasCalWeekViewHeader1(Context context, AttributeSet attrs) {
    super(context,attrs);
            this.context = (MyActivity) context;
        }

}

}
