onClick never called in a fragment, android

Question

I'm working on an android project using dynamically created fragments, and I struggle to catch the users events...

here-s the incriminate code.

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    Bundle data = getArguments();
    ArrayList<String> dataList = null;
    if (data != null) {
        dataList = data.getStringArrayList("jsonlist");
    }
    try {
        for(String object: dataList){
            json.add(new JSONObject(object));
        }
    } catch (JSONException e) {
        e.printStackTrace();
    }



    //Layout template

    ViewGroup maingroup= (ViewGroup) getActivity().findViewById(R.id.MainLayout);
    mainview = getActivity().getLayoutInflater().inflate(R.layout.finallayout, maingroup, false);
    ViewGroup myLayout= (ViewGroup) maingroup.findViewById(R.id.scrollcontentcontainer);

    for (int i = 0; i < json.size(); i++) {
        View  elementlayout = getActivity().getLayoutInflater().inflate(R.layout.relative, myLayout, false);
        createMainLayout(this.json.get(i), i, elementlayout, myLayout);
        //sur click sur layout

        elementlayout.setOnClickListener(this);
    }
    addShapeAndBottom();
    return mainview;
}

The fragment extends OnClickListener in order to catch the events. The user can click on a Layout. I have to add that the fragments are both dynamically added.

public class MainFragment extends Fragment implements View.OnClickListener

And this is what is suppose to happen when I click somewhere:

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub

    switch (v.getId()) {
        case R.id.scrollcontentcontainer:

                    System.out.print("test");
                    Fragment contentFragment = new CoreFragment();
                    FragmentManager fm = getActivity().getFragmentManager();
                    FragmentTransaction fragmentTransaction = fm.beginTransaction();
                    fragmentTransaction.replace(R.id.MainLayout, contentFragment);
                    fragmentTransaction.commit();

            break;

        default:
            System.out.print("test");
            break;
    }
}

The thing is when I'm trying to debug, I'm not even going into the onClick function which seems to be never called. I tried to declare the listener directly like this:

setOnClickListener(public void onClick(View v) {...})

but it was not working as well. My aim is to display another fragment on a click on a layout, elementlayout, which concerns several layout displayed like a list.

Thanks in advance !

EDIT 1

xml code. fimallayout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/MainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<RelativeLayout
    android:id="@+id/bottomcontent"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true">

</RelativeLayout>


<ScrollView
    android:id="@+id/scroller"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_above="@id/bottomcontent"
    android:layout_alignParentTop="true">

        <LinearLayout

and the template layout I want to click which has to go into the scrollcontentcontainer:

Some layouts are filled will contents and addShapeAndBottom(); add a footer.

EDIT2

Adding the listener on onActivityCreated doesn't change anything...

Answer 1

You can replace one fragment with the other via an activity. Have a look at this link. This is the most modular approach to go from one fragment to another.

Answer 2

Ok, I finally found the problem after some days.

It seems that the ScrollView was stealing the focus, making the layout inside and outside unable to receive the user's click.

Removing it fix the problem (which was not linked to the fragment, in the end...).

Answer 3

To make layout click-able need to set click-able property ofelementlayout :

elementlayout.setClickable(true);

Also set

android:duplicateParentState="true"

in R.layout.relative for all child Views.
