如何使用ImageButton和Exoplayer播放音频

implementation 'com.google.android.exoplayer:exoplayer:2.X.X'

<ImageButton
    android:id="@+id/playButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/play_button" />

<com.google.android.exoplayer2.ui.PlayerView
    android:id="@+id/playerView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

private SimpleExoPlayer player;
private ImageButton playButton;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // 初始化Exoplayer
    player = ExoPlayerFactory.newSimpleInstance(this);
    PlayerView playerView = findViewById(R.id.playerView);
    playerView.setPlayer(player);

    // 初始化ImageButton
    playButton = findViewById(R.id.playButton);
    playButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (player.getPlayWhenReady()) {
                player.setPlayWhenReady(false);
                playButton.setImageResource(R.drawable.play_button);
            } else {
                player.setPlayWhenReady(true);
                playButton.setImageResource(R.drawable.pause_button);
            }
        }
    });

    // 准备音频资源
    Uri audioUri = Uri.parse("https://example.com/audio.mp3");
    MediaSource mediaSource = new ExtractorMediaSource.Factory(
            new DefaultHttpDataSourceFactory("ExoplayerDemo"))
            .createMediaSource(audioUri);

    // 播放音频
    player.prepare(mediaSource);
}

@Override
protected void onDestroy() {
    super.onDestroy();
    player.release();
}
