How to programmatically add a layout to end of the current layout?

It seems like this should be easy but no luck so far. I set my Activity's main layout and then depending on which button is clicked I need to add a specific layout to end of the current main layout.

Main Activity:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //live_video_layout is a vertical LinearLayout
    setContentView(R.layout.live_video_layout);

    //Psuedo code for clarity; these layouts are ScrollViews that will sit under live_video_layout seen above
    if(button1 is clicked)
      {add R.id.first_layout under live_video_layout}

    else if(button2 is clicked)
      {add R.id.second_layout under live_video_layout
}

Any guidance here would be greatly appreciated, I'm all out of ideas.

You can prepare two Layouts in your xml file, the first one for your video views and the second for the dynamic layouts:

main_activity.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">


    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/live_video_container">

        <!-- include your live_video_layout.xml or directly add  your views-->

    </LinearLayout>

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/dynamic_layouts_container">
        <!-- here we'll add layouts from java code depending on buttons click -->
    </LinearLayout>
</LinearLayout>

Then in your activity:

    private LinearLayout mDynamicLayoutsContainer;
    private LayoutInflater mInflater;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main_activity);

        mInflater = LayoutInflater.from(context);
        mDynamicLayoutsContainer = (LinearLayout) findViewById(R.id.dynamic_layouts_container);

        if(button1 is clicked){

          View  firstLayout = mInflater.inflate(R.layout.first_layout , null, false);
          mDynamicLayoutsContainer.addView(firstLayout);

        }else if(button2 is clicked){

          View  secondLayout = mInflater.inflate(R.layout.second_layout , null, false);
          mDynamicLayoutsContainer.addView(secondLayout);

        }
   }

You need a third layout as parent. You put then R.layout.live_video_layout and the new one in this third layout.
