我有一个应用程序，可以从YouTube播放视频，并在我的MainActivity类中编写了链接。
我按预期在我的应用程序中播放了视频。
我尝试了PictureInPictureParams.Builder，但遇到了多个错误。
public class MainActivity extends YouTubeBaseActivity implements
YouTubePlayer.OnInitializedListener {
private static final int RECOVERY_REQUEST = 1;
private YouTubePlayerView youTubeView;
private MyPlayerStateChangeListener playerStateChangeListener;
private MyPlaybackEventListener playbackEventListener;
private YouTubePlayer player;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
youTubeView.initialize(Config.YOUTUBE_API_KEY, this);
playerStateChangeListener = new MyPlayerStateChangeListener();
playbackEventListener = new MyPlaybackEventListener();
final EditText seekToText = (EditText) findViewById(R.id.seek_to_text);
Button seekToButton = (Button) findViewById(R.id.seek_to_button);
seekToButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int skipToSecs = Integer.valueOf(seekToText.getText().toString());
player.seekToMillis(skipToSecs * 1000);
}
});
}
@Override
public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean wasRestored) {
this.player = player;
player.setPlayerStateChangeListener(playerStateChangeListener);
player.setPlaybackEventListener(playbackEventListener);
if (!wasRestored) {
player.cueVideo("I0D-fkypQQw"); // Plays https://www.youtube.com/watch?v=fhWaJi1Hsfo
}
}
@Override
public void onInitializationFailure(Provider provider, YouTubeInitializationResult errorReason) {
if (errorReason.isUserRecoverableError()) {
errorReason.getErrorDialog(this, RECOVERY_REQUEST).show();
} else {
String error = String.format(getString(R.string.player_error), errorReason.toString());
Toast.makeText(this, error, Toast.LENGTH_LONG).show();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RECOVERY_REQUEST) {
// Retry initialization if user performed a recovery action
getYouTubePlayerProvider().initialize(Config.YOUTUBE_API_KEY, this);
}
}
protected Provider getYouTubePlayerProvider() {
return youTubeView;
}
private void showMessage(String message) {
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
private final class MyPlaybackEventListener implements YouTubePlayer.PlaybackEventListener {
@Override
public void onPlaying() {
// Called when playback starts, either due to user action or call to play().
showMessage("Playing");
}
@Override
public void onPaused() {
// Called when playback is paused, either due to user action or call to pause().
showMessage("Paused");
}
@Override
public void onStopped() {
// Called when playback stops for a reason other than being paused.
showMessage("Stopped");
}
@Override
public void onBuffering(boolean b) {
// Called when buffering starts or ends.
}
@Override
public void onSeekTo(int i) {
// Called when a jump in playback position occurs, either
// due to user scrubbing or call to seekRelativeMillis() or seekToMillis()
}
}
private final class MyPlayerStateChangeListener implements YouTubePlayer.PlayerStateChangeListener {
@Override
public void onLoading() {
// Called when the player is loading a video
// At this point, it's not ready to accept commands affecting playback such as play() or pause()
}
@Override
public void onLoaded(String s) {
// Called when a video is done loading.
// Playback methods such as play(), pause() or seekToMillis(int) may be called after this callback.
}
@Override
public void onAdStarted() {
// Called when playback of an advertisement starts.
}
@Override
public void onVideoStarted() {
// Called when playback of the video starts.
}
@Override
public void onVideoEnded() {
// Called when the video reaches its end.
}
@Override
public void onError(YouTubePlayer.ErrorReason errorReason) {
// Called when an error occurs.
}
}
}
如何在视频中实现画中画模式，使视频缩小到应用程序的右下角。
现在我播放的是YouTube视频，在活动中播放。我希望将视频播放到画中画模式中。
