Media3 ExoPlayer
Hello Exoplayer
添加依赖
///media3
implementation "androidx.media3:media3-exoplayer:1.0.2"
implementation "androidx.media3:media3-exoplayer-dash:1.0.2"
implementation "androidx.media3:media3-ui:1.0.2"
网络权限和http
android:usesCleartextTraffic="true"
添加布局PlayerView
加载playerView
package com.example.mediaandroidjava;
import androidx.appcompat.app.AppCompatActivity;
import androidx.media3.common.MediaItem;
import androidx.media3.exoplayer.ExoPlayer;
import androidx.media3.ui.PlayerView;
import android.os.Bundle;
public class MainActivity extends AppCompatActivity {
private PlayerView playerView;
private ExoPlayer exoPlayer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//配置player
playerView = findViewById(R.id.player_view);
exoPlayer = new ExoPlayer.Builder(this).build();
playerView.setPlayer(exoPlayer);
MediaItem mediaItem = MediaItem.fromUri("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4");
exoPlayer.setMediaItem(mediaItem);
exoPlayer.prepare();
exoPlayer.play();
}
@Override
protected void onDestroy() {
super.onDestroy();
//释放资源
exoPlayer.release();
}
}
Player events
监听播放器的状态
///监听播放器的状态
exoPlayer.addListener(new Player.Listener() {
@Override
public void onIsPlayingChanged(boolean isPlaying) {
Player.Listener.super.onIsPlayingChanged(isPlaying);
Log.i(TAG, "isPlaying:" + isPlaying);
}
@Override
public void onPlayerError(@NonNull PlaybackException error) {
Player.Listener.super.onPlayerError(error);
@Nullable Throwable cause = error.getCause();
if (cause instanceof HttpDataSource.HttpDataSourceException) {
// An HTTP error occurred.
HttpDataSource.HttpDataSourceException httpError = (HttpDataSource.HttpDataSourceException) cause;
if (httpError instanceof HttpDataSource.InvalidResponseCodeException) {
Log.i(TAG, "HttpDataSource.InvalidResponseCodeException");
} else {
Log.i(TAG, "not HttpDataSource.InvalidResponseCodeException");
}
}
}
@Override
public void onEvents(Player player, Player.Events events) {
Player.Listener.super.onEvents(player, events);
if (events.contains(Player.EVENT_PLAYBACK_STATE_CHANGED) || events.contains(Player.EVENT_PLAY_WHEN_READY_CHANGED)) {
// uiModule.updateUi(player);
Log.i(TAG, "状态改变");
for (int i = 0; i
// Do something at the specified playback position.
Log.i(TAG, "视频播放至五秒时触发");
}).setLooper(Looper.getMainLooper()).setPosition(/* mediaItemIndex= */ 0, /* positionMs= */ 5_000)
// .setPayload(customPayloadData)
.setDeleteAfterDelivery(false).send();

Playlists
多视频播放列表
MediaItem mediaItemFirst = MediaItem.fromUri("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4");
MediaItem mediaItemSecond = MediaItem.fromUri("http://vjs.zencdn.net/v/oceans.mp4");
exoPlayer = new ExoPlayer.Builder(this).build();
exoPlayer.addMediaItem(mediaItemFirst);
exoPlayer.addMediaItem(mediaItemSecond);
调整播放列表
///调整播放列表
// 在位置1处添加一个媒体
exoPlayer.addMediaItem(/* index= */ 1, MediaItem.fromUri("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"));
// 将位置2处的媒体移到首位
exoPlayer.moveMediaItem(/* currentIndex= */ 2, /* newIndex= */ 0);
// 将位置0处的媒体移除
exoPlayer.removeMediaItem(/* index= */ 0);
替代播放列表和清除播放列表
///替代播放列表和清除播放列表
List newItems = ImmutableList.of(MediaItem.fromUri("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"), MediaItem.fromUri("http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"));
exoPlayer.setMediaItems(newItems, true);
exoPlayer.clearMediaItems();
查询播放列表
///查询播放列表
exoPlayer.getMediaItemAt(0);
exoPlayer.getMediaItemCount();
exoPlayer.getCurrentMediaItem();
exoPlayer.hasNextMediaItem();
exoPlayer.getNextMediaItemIndex();
重复模式(REPEAT_MODE_OFF关闭循环播放、REPEAT_MODE_ALL循环整个列表、REPEAT_MODE_ONE循环单个)
///重复模式(REPEAT_MODE_OFF关闭循环播放、REPEAT_MODE_ALL循环整个列表、REPEAT_MODE_ONE循环单个)
exoPlayer.setRepeatMode(Player.REPEAT_MODE_OFF);
exoPlayer.setRepeatMode(Player.REPEAT_MODE_ALL);
exoPlayer.setRepeatMode(Player.REPEAT_MODE_ONE);
随机播放
exoPlayer.setShuffleOrder(new ShuffleOrder.DefaultShuffleOrder(new int[]{2, 1, 0}, 1));
exoPlayer.setShuffleModeEnabled(true);
MediaItem设置Id
MediaItem mediaItem = new MediaItem.Builder().setUri(uri).setMediaId(mediaId).build();
MediaItem mediaItem = new MediaItem.Builder().setUri(uri).setTag(metadata).build();
监听媒体列表变化
exoPlayer.addListener(new Player.Listener() {
//监听播放过渡到另一个媒体
@Override
public void onMediaItemTransition(@Nullable MediaItem mediaItem, int reason) {
Player.Listener.super.onMediaItemTransition(mediaItem, reason);
@Nullable String metadata = null;
Log.i(TAG, "过渡");
if (mediaItem != null && mediaItem.localConfiguration != null) {
metadata = (String) mediaItem.localConfiguration.tag;
}
//updateUiForPlayingMediaItem(metadata);
}
//添加、删除或移动媒体项时，将调用 立即与 .此回调是 即使玩家尚未做好准备，也会调用。
@Override
public void onTimelineChanged(@NonNull Timeline timeline, int reason) {
Player.Listener.super.onTimelineChanged(timeline, reason);
if (reason == TIMELINE_CHANGE_REASON_PLAYLIST_CHANGED) {
//updateUiForPlaylist(timeline);
}
}
});
