I have problem with Android TV and I need your help.

Below is layout code:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

>



<VideoView

    android:id="@+id/videoView"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:layout_gravity="center"

    />



<fragment

    android:id="@+id/playback_controls_fragment"

    android:name="com.sharewis.leonettv.PlaybackOverlayFragment"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    />

And layout rendered:

How can I set position for Playback control of Android TV (etc: bottom, top...)?

I manual override padding dimen of Playback control (include top and bottom) with lb_playback_controls_padding_top and lb_playback_controls_padding_bottom

change the ViewGroup from to

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    >



    <VideoView

        android:id="@+id/videoView"

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:layout_gravity="center"

        />



    <fragment

        android:id="@+id/playback_controls_fragment"

        android:name="com.sharewis.leonettv.PlaybackOverlayFragment"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_alignParentBottom="true"

        android:layout_centerHorizontal="true"

        />

</RelativeLayout>

and add two xml attributes layout_alignParentBottom and layout_centerHorizontal to fragment as shown above.

It aligns playback_control_fragment bottom edge of this view match the bottom edge of the parent and centers this child horizontally within its parent.

After updating to API v28 / leanback support v28.x.x I found the answer provided by Louis Nguyen to no longer be working.

Looking at the PlaybackSupportFragment.setVerticalGridViewLayout() source code for API 28 / Leanback support 28.x.x, one can see Google changed how this alignment is being set.

TLDR

If you're using API v28 / Leanback support v28.x.x :

• override the dimen value "lb_playback_other_rows_center_to_bottom"


• A value of 135dp positions the playback controls to a position similar of that when we were using API v26 / LeanbackSupport v26.

If you're using API v26 / Leanback support v26.x.x

• override the dimen value "lb_playback_controls_padding_top"
  


• A value of 300dp keeps the controls at a place around the bottom with some good bottom margin
