Adding Layout to a ViewGroup Android

Question

I have a flying in menu which based on ViewGroup. I want that there will be a basic layout and in any activity i would be able to insert to the view group new layout and afterwards to erase it. But it doesn't work!!! Can you help me please.

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 the setContentView(int) instead of the onCreate(Bundle).

Make sure your base layout XML has a ViewGroup (FrameLayout, for example) available to put each Activity's content.

When overriding the setContentView(int), inflate your base layout first then inflate the Activity's layout and place the Activity's layout on the FrameLayout available.
