按子片段访问父片段 [英] access parent fragment by child fragment

问题描述

这是我的子片段，如何从该片段访问我的父片段，请帮助我修复它

this is my child fragment and how to access my parent fragment from this fragment please help me to fix it

public class Profilefragmant extends Fragment {
public Profilefragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.profile_layout, container, false);

    TextView VE = (TextView) rootView.findViewById(R.id.profile_view_enquiry);
    VE.setOnClickListener(new View.OnClickListener(){
        public void onClick (View view){
            Fragment fragment = null;

            fragment = new Enquiryfragment();
            replaceFragment(fragment);
        }
    });



    return rootView;
}
public void replaceFragment(Fragment someFragment) {
    android.support.v4.app.FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.replace(R.id.containerView, someFragment);
    transaction.addToBackStack(null);
    transaction.commit();
}
}

这是我在运行项目时遇到的错误

this is my error while run the project

 java.lang.IllegalArgumentException: No view found for id 0x7f0c0099 (com.knrmarine.knr:id/containerView) for fragment EnquiryActivity{3754711 #2 id=0x7f0c0099} 

这是我的Enquiryfragment代码:

public class Enquiryfragmant extends Fragment {
public Enquiryfragment(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.enquiry_layout, container, false);
return rootView;}}

推荐答案

您可以通过以下方式获取父Fragment的引用:

You can get parent Fragment's reference by :

ParentFragment parentFrag = ((ParentFragment)ChildFragment.this.getParentFragment());
parentFrag.someMethod();

我在ViewPager中使用了它.如果您还有其他要求，则Interface或EventBus是常规的两个.

I used this in my ViewPager. If you have other requirement, Interface or EventBus are two of the general ones.
