I am getting data from this API and have parsed it into a listview within a fragment. However, I can't seem to get it displayed on the Main Activity. Can anyone point me in the right direction please?

Un comment the onCreate method in searchFragment because your fragment is not inflating any layout
Fragments can be put into a layout using FragmentManager.
Add replace onCreate of your MainActivity with following.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fts = fragmentManager.beginTransaction();
Fragment fragment = new SearchFragment();
String fragmentTag = "SearchFragment";
fts.add(R.id.main_container, fragment, fragmentTag);
fts.commit();
}
Change your layout_activity_main.xml to following. You don't need a listview here. Just make sure you have a layout container main_container to place your fragment in.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout android:id="#+id/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</FrameLayout>
<!-- Main ListView
Always give id value as list(#android:id/list)
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#null"/>
-->
</LinearLayout>
I think your problem is caused by Jason parsing.
private static final String TAG_CODING_SYSTEM = "codingSystem";
Jason key is case sensitive. But please try to debug by yourself next time, it's the only way to become a better coder. Cheers!

Regarding the Model-View-Controller approach, all you need to do is create a model with the data that matches your search and hand it tho the view (your list view) that will display it.
You probably want a setOnQueryTextListener which can filter your results when text is written in SearchView.
There is an existing post explaining this quite well, Implementing SearchView in action bar.
I'm new to Android development and I have a problem with setting up getting into the next activity when I click an item in my listview within my ListFragment.

SearchFragment extends ListFragment. In a ListFragment, getListView() cannot be called in onCreateView(), because onCreateView() is creating the fragment's content view and has not yet completed. The call to getListView() in SearchFragment is the cause of the exception.
Move the the call to getListView() and related to code to one of the fragment lifecycle methods that is called after onCreateView(), such as onViewCreated() or onActivityCreate(). For example:
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
ListView lv = getListView();
// Listview on item click listener
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String name = ((TextView) view.findViewById(R.id.name))
.getText().toString();
String code = ((TextView) view.findViewById(R.id.code))
.getText().toString();
// Starting single contact activity
Intent in = new Intent(getActivity().getApplicationContext(),
Details.class);
in.putExtra(TAG_NAME, name);
in.putExtra(TAG_CODE, code);
startActivity(in);
}
});
}

Below two things will fix your problem -
Extend your fragment by ListFragment not with Fragment.
Delete below method.

What I have to change, so I can use that as a fragment?
Edit:
i tried to change the code a little bit following some tutorials on the web...
now it works better, but there is still some problems with onPostExecute...
the doInBackground gets all parameters from mysql. i can track that with debug, but somehow after doInBackground it get's there is an error..

int index=0;
MyListFragment f = MyListFragment.newInstance(index);
FragmentTransaction ft = getSupportFragmentManager()
.beginTransaction();
ft.replace(R.id.mylist, f);
ft.commit();
}//end oncreate
}//end activity
