Android : Change MediaController position on rotation

I'm trying to change MediaController's anchor dynamically on orientation changes. And after all my attemts this isn't working as needed.

Perhabs you could point me my mistake.

In few words:

Portrait mode:

1. weightSum = 1.


2. SurfaceView weight: 0.4


3. MediaController and HorizontalScrollView weight: 0.6


4. MediaController always visible and not hiding

Landscape mode:

1. 
   

   SurfaceView weight: 0.0 (full screen)

   
   


2. 
   

   MediaControlls = View.Gone (I need to change its anchor to SurfaceView. And popup onTouch. But how??)

CODE CODE:

player.xml:

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:keepScreenOn="true"
    tools:context="tenkol.design.com.imbrecords.ActivityExoPlayer"
    android:weightSum="1"
    android:orientation="vertical">

    <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/surface_wrapper"
        android:layout_weight="0.4">

        <com.google.android.exoplayer.VideoSurfaceView
            android:id="@+id/surface_view"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center" />

        <View
            android:id="@+id/shutter"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@android:color/black" />
    </FrameLayout>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="0.6"
        android:orientation="vertical">

        <FrameLayout
            android:id="@+id/controls_wrapper"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="2dp">
        </FrameLayout>

        <HorizontalScrollView
            android:id="@+id/myGallery"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="0dp">

            <LinearLayout
                android:id="@+id/channelsScrollView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:orientation="horizontal"
                android:paddingBottom="5dp"
                android:paddingTop="5dp"
                />
        </HorizontalScrollView>

    </LinearLayout>

</LinearLayout>

code with transformation:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    if (Global.getScreenOrientation(this) == Configuration.ORIENTATION_LANDSCAPE) {
        //hide action bar
        getSupportActionBar().hide();
        if (myGallery != null) {
            //hide HorizontalScrollView
            myGallery.setVisibility(View.GONE);
        }
        //make surface fullscreen
        surfaceWrapper.setLayoutParams(new LinearLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT, 0f));
        controlsWrapper.setLayoutParams(new LinearLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT, 0f));
        //hide mediaController
        mc.hide();
        controlsWrapper.setVisibility(View.GONE);
    }
    if (Global.getScreenOrientation(this) == Configuration.ORIENTATION_PORTRAIT) {
        //and here restore everything
        getSupportActionBar().show();
        if (myGallery != null) {
            myGallery.setVisibility(View.VISIBLE);
        }

        surfaceWrapper.setLayoutParams(new LinearLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT, FrameLayout.LayoutParams.FILL_PARENT, 0.4f));
        controlsWrapper.setLayoutParams(new LinearLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT, FrameLayout.LayoutParams.WRAP_CONTENT, 0.6f));
        controlsWrapper.setVisibility(View.VISIBLE);
    }
}

What I tried:

1) When Landscape: create another mediaController and bind to root view(doesnt work):

  mediaController.setAnchorView(root);
  mediaController.setMediaPlayer(player.getPlayerControl());
  mediaController.setEnabled(true);
  mediaController.show(3);

2) When Landscape: change the anchor of previous MediaController (Nah).

  mc.setAnchorView(surfaceWrapper);
  mc.show(3);

So how can I change the MediaController's anchor to SurfaceView dynamically in LANDSCAPE mode?

Maybe someone faced such problem already. Please give me a hint or solution. Appreciate any help. Really confused with it already..

P.S. Tell if some more code needed.
