class:

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      this.root = (flyoutcontainer) this.getlayoutinflater().inflate(r.layout.activity_main, null);      this.setadditionallayout(findviewbyid(r.id.physical_layout));      this.setcontentview(root); }

viewgroup:

    <com.nurielweizmann.calculator.view.viewgroup.flyoutcontainer xmlns:android="http://schemas.android.com/apk/res/android"                                                               android:layout_width="match_parent"                                                               android:layout_height="match_parent"> <relativelayout         xmlns:android="http://schemas.android.com/apk/res/android"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:background="#444488"         android:orientation="vertical"         android:id="@+id/menu"> ............ </relativelayout> </com.nurielweizmann.calculator.view.viewgroup.flyoutcontainer>

function:

    flyoutcontainer root;     public void setadditionallayout(view view){         root.addview(view,1);     }

thanks in advance

try overriding setcontentview(int) instead of oncreate(bundle).

make sure base layout xml has viewgroup (framelayout, example) available put each activity's content.

when overriding setcontentview(int), inflate base layout first inflate activity's layout , place activity's layout on framelayout available.
