Custom UI on exoplayer sample

ok, that took me half a day, until i didn't dive into the library code and found such text:

To customize the layout of PlaybackControlView throughout your app, or just for certain configurations, you can define exo_playback_control_view.xml layout file in your application res/layout directories. These layouts will override the one provided by the ExoPlayer library, and will be inflated for use by PlaybackControlView.

Full text: https://github.com/google/ExoPlayer/blob/release-v2/library/ui/src/main/java/com/google/android/exoplayer2/ui/PlaybackControlView.java

Also, want to add that u can specify custom layout in PlayerView like so:

<com.google.android.exoplayer2.ui.SimpleExoPlayerView android:id="@+id/player_view"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      app:controller_layout_id="@layout/custom_controls"/>

Customizing the ExoPlayer's UI is pretty simple. If you look at the ExoPlayer source, the layout res directory contains the file exo_player_control_view.xml that points to (includes) another layout - exo_playback_control_view.

  1. Copy the contents of the layout resource - exo_playback_control_view.xml
  2. Create a Layout Resource file with any name of your choice - eg: custom_exo_playback_control_view.xml. Paste the copied contents to the new xml
  3. Make whatever changes to the UI widgets as required. Don't change the Id attribute of any widget/control.
  4. Point the custom exoPlayer UI resource in your layout file that contains the PlayerView.

Here is the custom_exo_controller_view xml that I created from the original. I wanted a different background color for the player controls and different button and progress view colors:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom"
    android:background="@drawable/attachment_document_desc_bg"
    android:layoutDirection="ltr"
    android:orientation="vertical"
    android:paddingStart="20dp"
    android:paddingEnd="20dp"
    tools:targetApi="28">

  <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:gravity="center"
      android:orientation="horizontal"
      android:paddingTop="4dp">

    <ImageButton
        android:id="@id/exo_prev"
        style="@style/ExoMediaButton.Previous"
        android:tint="@color/colorPrimaryDark"
        android:tintMode="src_in" />

    <ImageButton
        android:id="@id/exo_rew"

    <ImageButton
        android:id="@id/exo_repeat_toggle"
        style="@style/ExoMediaButton"
        android:tint="@color/colorPrimaryDark"
        android:tintMode="src_in" />

    <ImageButton
        android:id="@id/exo_play"
        style="@style/ExoMediaButton.Play"
        android:tint="@color/colorPrimaryDark"
        android:tintMode="src_in" />

    <ImageButton
        android:id="@id/exo_pause"
        style="@style/ExoMediaButton.Pause"
        android:tint="@color/colorPrimaryDark"
        android:tintMode="src_in" />

    <ImageButton
        android:id="@id/exo_ffwd"
        style="@style/ExoMediaButton.FastForward"
        android:tint="@color/colorPrimaryDark"
        android:tintMode="src_in" />

    <ImageButton
        android:id="@id/exo_next"
        style="@style/ExoMediaButton.Next"
        android:tint="@color/colorPrimaryDark"
        android:tintMode="src_in" />

    <ImageButton
        android:id="@id/exo_vr"
        style="@style/ExoMediaButton.VR"
        android:tint="@color/colorPrimaryDark"
        android:tintMode="src_in" />

  </LinearLayout>

  <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginTop="4dp"
      android:gravity="center_vertical"
      android:orientation="horizontal">

    <TextView
        android:id="@id/exo_position"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:includeFontPadding="false"
        android:paddingLeft="4dp"
        android:paddingRight="4dp"
        android:textColor="#ff323232"
        android:textSize="14sp"
        android:textStyle="bold" />

    <com.google.android.exoplayer2.ui.DefaultTimeBar
        android:id="@id/exo_progress"
        android:layout_width="0dp"
        android:layout_height="26dp"
        android:layout_weight="1"
        app:played_color="@color/colorPrimaryDark"
        app:unplayed_color="@color/gray" />

    <TextView
        android:id="@id/exo_duration"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:includeFontPadding="false"
        android:paddingLeft="4dp"
        android:paddingRight="4dp"
        android:textColor="#ff323232"
        android:textSize="14sp"
        android:textStyle="bold" />

  </LinearLayout>

</LinearLayout>

Below is the code that I use for the player. Notice, the xml attribute app:controller_layout_id points to the custom controller view thats defined above.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="20dp">

  <com.google.android.exoplayer2.ui.PlayerView
      android:id="@+id/video_view"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:layout_gravity="center"
      app:auto_show="true"
      app:controller_layout_id="@layout/custom_exo_controller_view"
      app:fastforward_increment="10000"
      app:repeat_toggle_modes="none"
      app:resize_mode="fixed_width"
      app:rewind_increment="10000"
      app:surface_type="surface_view"
      app:use_controller="true" />

</FrameLayout>

That should get the UI the way you want.

You can add extra controls as you need in the custom controller and in your code, find the control with findViewById() and write event listeners, etc.
