Failed to start Activity ComponentInfo android.view.InflateException: binary line of XML file # 6: error inflating a class fragment using ListFragment

I am new to Android and trying to make a simple .Im application trying to display a list of arrays in the Snippets section. This list is constantly updated as it is controlled by XML data from the website. The SInce array list is dynamic, using onActivityCreated, not onCreateView. Below is my code

package com.example.myearthquake;

public class EarthquakeListFragment extends ListFragment {

  ArrayAdapter<Quake> aa;
  ArrayList<Quake> earthquakes = new ArrayList<Quake>();

  @Override
  public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    int layoutID = android.R.layout.simple_list_item_1;
    aa = new ArrayAdapter<Quake>(getActivity(), layoutID , earthquakes);
    setListAdapter(aa);
    Log.d("EarthQuake","onActivityCreated");
          }

Class MainActivity

public class Earthquake extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Log.d("EarthQuake","Activity");
}

Layout

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent">
 <fragment android:name="com.paad.myearthquake.EarthquakeListFragment"
 android:id="@+id/EarthquakeListFragment"
 android:layout_width="match_parent" 
 android:layout_height="match_parent" 
 />
  </LinearLayout>
