this mt layout folder image

need define fragment in xml this.

<relativelayout  android:id="@+id/main_tasklist_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_torightof="@+id/main_viewmenu_layout" android:layout_below="@+id/main_tasklist_outer">   <fragment          class="com.organisemee.fragment.tasklistfragment"         android:id="@+id/tasklistfrag"         android:layout_width="match_parent"         android:layout_height="match_parent"/>  </relativelayout>

to call fragment put code in java file

            fragment f = listfragment();             fragmenttransaction listfragft = getfragmentmanager().begintransaction();             listfragft.replace(r.id.main_tasklist_layout, f);             listfragft.settransition(fragmenttransaction.transit_fragment_fade);             listfragft.addtobackstack(null);             listfragft.commit();

this works fine in change both orientation, landscape portrait , vice versa.
