如何使用自定义 UI 初始化 android Exoplayer 播放和暂停按钮？

Question

我正在使用 Exoplayer 2.17.1 并且想要自定义 UI。一切正常，但无法初始化播放和暂停按钮，正如您在照片中看到的那样，并显示它们，但它不起作用。

在fragment_home.xml中：

  <com.google.android.exoplayer2.ui.StyledPlayerView
                android:id="@+id/styledPlayerView"
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_alignParentStart="true"
                android:layout_alignParentTop="true"
                android:layout_alignParentEnd="true"
                android:layout_alignParentBottom="true"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:layout_centerVertical="true"
                android:layout_margin="0dp"
                android:contentDescription=""
                android:padding="0dp"
                android:scaleType="fitCenter"
                app:use_controller="true"
                app:player_layout_id="@layout/exo_player_view"
                app:controller_layout_id="@layout/custom_exo_layout"
                app:layout_constraintBottom_toBottomOf="parent"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent"
                tools:ignore="PrivateResource" />

爪哇：

@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) {
    binding = FragmentHomeBinding.inflate(inflater, container, false);
    root = binding.getRoot();

  StyledPlayerView  styledPlayerView = binding.styledPlayerView;
  ExoPlayer  exoPlayer = new ExoPlayer.Builder(context)
            .build();

    styledPlayerView.setPlayer(exoPlayer);
    styledPlayerView.setKeepScreenOn(true);

    exoPlayer.addListener(new Player.Listener() {
        @Override
        public void onPlaybackStateChanged(int playbackState) {
            Player.Listener.super.onPlaybackStateChanged(playbackState);
          if (playbackState == Player.STATE_BUFFERING)
                progressBarVideoHomeLoader.setVisibility(View.VISIBLE);
            else if (playbackState == Player.STATE_READY)
                progressBarVideoHomeLoader.setVisibility(View.INVISIBLE);
        }
    });

    exoPlayer.addMediaItem(MediaItem.fromUri(Uri.parse(videoURL)));
    exoPlayer.prepare();
    exoPlayer.play();
  return root;

}

可点击视图.xml：

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="clickableview">
     <item name="colorControlHighlight">@android:color/darker_gray</item>
     <item name="android:background">?selectableItemBackgroundBorderless</item>
  </style>
</resources>

在 StyledPlayerView 中，没有两个播放和暂停视频的按钮，您应该更改以下代码：

<ImageView
    android:id="@id/exo_play"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/clickableview"
    app:srcCompat="@drawable/exo_icon_play" />

<ImageView
    android:id="@id/exo_pause"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/clickableview"
    app:srcCompat="@drawable/exo_icon_pause" />

到：

   <ImageView
        android:id="@+id/exo_play_pause"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:theme="@style/clickableview"
        style="@style/ExoStyledControls.Button.Center.PlayPause"/>
