my fragment content view

  @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View rootView  = inflater.inflate(R.layout.fragment_navigation, container, false);
    Element versionElement = new Element();
    versionElement.setTitle("Version 6.2");

    Element adsElement = new Element();
    adsElement.setTitle("Advertise with us");

    View aboutPage = new AboutPage(getActivity())
            .isRTL(false)
            .addItem(versionElement)
            .addItem(adsElement)
            .addGroup("Connect with us")
            .addEmail("[email protected]")
            .addFacebook("the.medy")
            .addTwitter("medyo80")
            .addYoutube("UCdPQtdWIsg7_pi4mrRu46vA")
            .addPlayStore("com.ideashower.readitlater.pro")
            .addInstagram("medyo80")
            .addGitHub("medyo")
            .create();

    setContentView(aboutPage);
    return rootView;
}

I am getting error in the second last line how to solve this. The following library will work in api 20+ library https://github.com/medyo/android-about-page

On a fragment you don't call setContentView explicitly, you return the view after inflating it, as you are. So instead of calling setContentView consider adding the view aboutPage to rootView or one of its children views.

For example, say your layout R.layout.fragment_navigation contains a LinearLayout (or any other ViewGroup for that matter) with an ID of content. You would do this, before your return statement:

LinearLayout content = (LinearLayout) rootView.findViewById(R.id.content);
content.addView(aboutPage); //<-- Instead of setContentView(aboutPage)

You'll have to adjust this to your layout, I don't know what's inside it.

Full example

fragment.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/container">
</RelativeLayout>

CustomFragment.java

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

        ViewGroup viewGroup = (ViewGroup) inflater.inflate(R.layout.fragment, container, false);
        Element versionElement = new Element();
        versionElement.setTitle("Version 6.2");

        Element adsElement = new Element();
        adsElement.setTitle("Advertise with us");

        View aboutPage = new AboutPage(getActivity())
                .isRTL(false)
                .addItem(versionElement)
                .addItem(adsElement)
                .addGroup("Connect with us")
                .addEmail("[email protected]")
                .addFacebook("the.medy")
                .addTwitter("medyo80")
                .addYoutube("UCdPQtdWIsg7_pi4mrRu46vA")
                .addPlayStore("com.ideashower.readitlater.pro")
                .addInstagram("medyo80")
                .addGitHub("medyo")
                .create();

        viewGroup.addView(aboutPage);
        return viewGroup;
    }
}
