以下是我的android listview的代码

listitem.xml 

<?xml version="1.0" encoding="utf-8"?>
<fragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:name="com.mylistview.ExtendedFragmentLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/t2">
</fragment>

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
     />
</LinearLayout>

CustomAdapter.java 

public View getView(int position, View convertView, ViewGroup parent) {

  ViewHolder holder = null;

  LayoutInflater mInflater = (LayoutInflater) context
    .getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
   convertView = mInflater.inflate(R.layout.listitem, null);
  return convertView;
 }

ExtendedFragmentLayout.java

public class ExtendedFragmentLayout extends Fragment
{

    Context context;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup view,
            Bundle savedInstanceState) {
        super.onCreateView(inflater, view,savedInstanceState);

         TextView textName = new TextView(context);
        textName.setText("Text1");
        textName.setTextSize(18);
        ViewGroup.MarginLayoutParams textNameParams = new ViewGroup.MarginLayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
        textNameParams.leftMargin = 90;
        textNameParams.topMargin = 15;


        TextView dateDisplay = new TextView(context);
        dateDisplay.setText("Today");
        dateDisplay.setTextSize(14);
        ViewGroup.MarginLayoutParams dateDisplayParams = new ViewGroup.MarginLayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
        dateDisplayParams.leftMargin = 250;
        dateDisplayParams.topMargin = 8;

        RelativeLayout layout1 = new RelativeLayout(context);
        layout1.addView(textNameParams , textNameParams );
        layout1.addView(dateDisplay, dateDisplayParams);

return layout1;
}

我在使用此自定义片段时遇到错误，我将我的MainActivity类作为
