ExoPlayer - Show PlayerControlView throughout playback of audio clip

Question

I have recently added ExoPlayer to my Android project. Setting it up, and getting an audio clip to play was relatively simple thanks to their website. I am able to get the audio file from my API and play it, but the issue is, the PlayerControlView vanishes moments after playback has started. Is there a way I can force the PlayerControlView to stay throughout playback of audio clip? Here is my XML of the fragment containing the PlayerControlView:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

After taking a close look at documentation, I found this information:

The following attributes can be set on a PlayerControlView when used in a layout XML file:

show_timeout - The time between the last user interaction and the controls being automatically hidden, in milliseconds. Use zero if the controls should not automatically timeout.

So, I went into my PlayerControlView and set the show_timeout attribute to zero. Now the player control view does not disappear after some time.

<com.google.android.exoplayer2.ui.PlayerControlView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:show_timeout="0"
    app:layout_constraintBottom_toBottomOf="parent"
    android:id = "@+id/CreateHousePlayerView"
    android:layout_margin="5dp"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintTop_toBottomOf="@id/NewHouseContentImage"
    />
