我在我的活动中使用ExoPlayer，我想要的是在纵向和横向模式下顺畅地播放视频。为此我正在做的是onpause我保存currentPlayerPosition并寻找玩家到那个位置onresume但在旋转时面对一个混蛋，视频会暂停一段时间并播放到已保存的位置。
我的代码如下，请帮助我如何顺利切换模式肖像和风景。谢谢
@Override
public void onPause() {
super.onPause();

最后，在浪费了2天之后我找到了它。 简单地将它添加到清单中并将适用于所有Android版本？
android:configChanges="orientation|screenSize|layoutDirection"
喝彩！
答案 1 :(得分：2)
如果您希望视频在方向更改时恢复，可以将其添加到您的代码requests
android:configChanges="keyboardHidden|orientation|screenSize"答案 2 :(得分：0)
无需任何其他编码，只需添加此行
android:configChanges="keyboardHidden|orientation|screenSize"
AndroidManifest.xml活动部分中。
答案 3 :(得分：0)
我在这方面也浪费了很多时间。看看它EXO PLAYER 2.11.2
implementation 'com.google.android.exoplayer:exoplayer:2.11.2'
STEP-1进行一项活动，在该活动中以意图传递字符串url。
public class VideoPlayerActivity extends Activity {
public static final String sURL_KEY = "STREAMING_URL_KEY";
public static final String sTOAST_TEXT = "Unable to stream, no media found";
static final String LOADING = "PLAYER_LOADING";
static final String STOPPED = "PLAYER_STOPPED";
static final String PAUSED = "PLAYER_PAUSED";
static final String PLAYING = "PLAYER_PLAYING";
static final String IDLE = "PLAYER_IDLE";
private static final String TAG = "StreamMediaActivity";
int orientation;
private Uri streamUrl;
private SimpleExoPlayer mPlayer;
private PlayerView playerView;
private ProgressBar progressBar;
private String mPlayerStatus;
private long mPlaybackPosition = 0L;
private boolean mIsPlayWhenReady = true;
private int mCurrentWindow = 0;
private Display display;
private String STATE_RESUME_WINDOW = "resumeWindow";
private String STATE_RESUME_POSITION = "resumePosition";
private String STATE_PLAYER_FULLSCREEN = "playerFullscreen";
private boolean mExoPlayerFullscreen = false;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
fullScreen();
display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
orientation = display.getRotation();
setContentView(R.layout.activity_video_player);
playerView = findViewById(R.id.player_view);
progressBar = findViewById(R.id.progressBar_player);
// Pass a string uri to this class
String urlString = getIntent().getStringExtra(sURL_KEY);
if (urlString != null) {
streamUrl = Uri.parse(urlString);
} else {
Toast.makeText(this, sTOAST_TEXT, Toast.LENGTH_LONG).show();
finish();
}
}
@Override
protected void onStart() {
super.onStart();
initPlayer();
}
@Override
protected void onResume() {
super.onResume();
if (mPlaybackPosition != 0L && mPlayer != null) {
mPlayer.seekTo(mCurrentWindow, mPlaybackPosition);
}
}
@Override
protected void onStop() {
super.onStop();
}
@Override protected void onPause() {
super.onPause();
releasePlayer();
}
private void initPlayer() {
// ESTABLISH THE DATA SOURCE FROM URL
// here i'm playing local video file that's
// why using the DefaultDataSourceFactory but you
//may use DefaultHttpDataSourceFactory to stream
//online videos
DataSource.Factory dataSourceFactory =
new DefaultDataSourceFactory(this, Util.getUserAgent(this, getApplicationInfo().name));
MediaSource mediaSource =
new ProgressiveMediaSource.Factory(dataSourceFactory).createMediaSource(
streamUrl);
// CREATE A NEW INSTANCE OF EXO PLAYER
if (mPlayer == null) {
mPlayer = new SimpleExoPlayer.Builder(this, new DefaultRenderersFactory(this)).build();
playerView.setPlayer(mPlayer);
progressBar.setVisibility(View.VISIBLE);
}
mPlayer.setPlayWhenReady(mIsPlayWhenReady);
mPlayer.seekTo(mCurrentWindow, mPlaybackPosition);
// PREPARE MEDIA PLAYER
mPlayer.prepare(mediaSource, true, false);
mPlayer.addListener(new Player.EventListener() {
@Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
switch (playbackState) {
case Player.STATE_BUFFERING:
mPlayerStatus = LOADING;
runOnUiThread(() -> progressBar.setVisibility(View.VISIBLE));
break;
case Player.STATE_ENDED:
mPlayerStatus = STOPPED;
break;
case Player.STATE_READY:
mPlayerStatus = (playWhenReady) ? PLAYING : PAUSED;
runOnUiThread(() -> progressBar.setVisibility(View.INVISIBLE));
break;
default:
mPlayerStatus = IDLE;
break;
}
}
@Override
public void onPlayerError(ExoPlaybackException error) {
Toast.makeText(VideoPlayerActivity.this, "Something went wrong", Toast.LENGTH_SHORT).show();
finish();
}
});
}
@Override protected void onSaveInstanceState(Bundle outState) {
mExoPlayerFullscreen = !mExoPlayerFullscreen;
super.onSaveInstanceState(outState);
outState.putInt(STATE_RESUME_WINDOW, mCurrentWindow);
outState.putLong(STATE_RESUME_POSITION, mPlaybackPosition);
outState.putBoolean(STATE_PLAYER_FULLSCREEN, mExoPlayerFullscreen);
super.onSaveInstanceState(outState);
}
public void fullScreen() {
View decorView = getWindow().getDecorView();
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
}
private void releasePlayer() {
if (mPlayer != null) {
mPlayer.stop();
mPlaybackPosition = mPlayer.getCurrentPosition();
mCurrentWindow = mPlayer.getCurrentWindowIndex();
mIsPlayWhenReady = mPlayer.getPlayWhenReady();
playerView.setPlayer(null);
mPlayer.release();
mPlayer = null;
}
}
}
第2步：进行XML布局
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:background="@android:color/black">
<FrameLayout
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<com.google.android.exoplayer2.ui.PlayerView
android:id="@+id/player_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintBottom_toBottomOf="parent"
android:keepScreenOn="true"
app:use_controller="true"
app:resize_mode="fit"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ProgressBar
android:id="@+id/progressBar_player"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
</FrameLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
第3步：使用其他活动的意图启动VideoPlayerActivity
Intent streamVideoIntent = new Intent(context, VideoPlayerActivity.class);
streamVideoIntent.putExtra(sURL_KEY, stringUrl);
context.startActivity(streamVideoIntent);
步骤4：最后将活动添加到清单
<activity android:name=".ui.videoplayer.VideoPlayerActivity"
android:configChanges="orientation|screenSize|layoutDirection"
/>
