我已经使用 youtube player api
成功播放了 youtube 视频。但是我需要在按下后退按钮时在后台运行它。我用谷歌搜索了很多但什么也没找到请帮助我实现这一点。提前致谢
这是我的代码-
public class FullscreenDemoActivity extends YouTubeFailureRecoveryActivity
implements View.OnClickListener,
YouTubePlayer.OnFullscreenListener {
// private MyPlaybackEventListener myPlaybackEventListener;
private static final int PORTRAIT_ORIENTATION = Build.VERSION.SDK_INT < 9 ? ActivityInfo.SCREEN_ORIENTATION_PORTRAIT
: ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT;
private LinearLayout baseLayout;
private YouTubePlayerView playerView;
public YouTubePlayer player;
private Button fullscreenButton;
private CompoundButton checkbox;
private View otherViews;
private boolean fullscreen;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fullscreen_demo);
baseLayout = (LinearLayout) findViewById(R.id.layout);
playerView = (YouTubePlayerView) findViewById(R.id.player);
fullscreenButton = (Button) findViewById(R.id.fullscreen_button);
checkbox = (CompoundButton) findViewById(R.id.landscape_fullscreen_checkbox);
otherViews = findViewById(R.id.other_views);
playerView.initialize(DeveloperKey.DEVELOPER_KEY, this);
}
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,
YouTubePlayer player, boolean wasRestored) {
this.player = player;
setControlsEnabled();
// Specify that we want to handle fullscreen behavior ourselves.
player.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CUSTOM_LAYOUT);
player.setOnFullscreenListener(this);
if (!wasRestored) {
player.cueVideo("avP5d16wEp0");
}
int controlFlags = player.getFullscreenControlFlags();
setRequestedOrientation(PORTRAIT_ORIENTATION);
controlFlags |= YouTubePlayer.FULLSCREEN_FLAG_ALWAYS_FULLSCREEN_IN_LANDSCAPE;
player.setFullscreenControlFlags(controlFlags);
player.play();
}
@Override
protected YouTubePlayer.Provider getYouTubePlayerProvider() {
return playerView;
}
@Override
public void onClick(View v) {
player.setFullscreen(!fullscreen);
}
private void doLayout() {
LinearLayout.LayoutParams playerParams = (LinearLayout.LayoutParams) playerView
.getLayoutParams();
if (fullscreen) {
// When in fullscreen, the visibility of all other views than the
// player should be set to
// GONE and the player should be laid out across the whole screen.
playerParams.width = LayoutParams.MATCH_PARENT;
playerParams.height = LayoutParams.MATCH_PARENT;
otherViews.setVisibility(View.GONE);
} else {
otherViews.setVisibility(View.VISIBLE);
ViewGroup.LayoutParams otherViewsParams = otherViews
.getLayoutParams();
if (getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
playerParams.width = otherViewsParams.width = 0;
playerParams.height = WRAP_CONTENT;
otherViewsParams.height = MATCH_PARENT;
playerParams.weight = 1;
baseLayout.setOrientation(LinearLayout.HORIZONTAL);
} else {
playerParams.width = otherViewsParams.width = MATCH_PARENT;
playerParams.height = WRAP_CONTENT;
playerParams.weight = 0;
otherViewsParams.height = 0;
baseLayout.setOrientation(LinearLayout.VERTICAL);
}
setControlsEnabled();
}
}
private void setControlsEnabled() {
checkbox.setEnabled(player != null
&& getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT);
fullscreenButton.setEnabled(player != null);
}
@Override
public void onFullscreen(boolean isFullscreen) {
fullscreen = isFullscreen;
doLayout();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// System.out.println(getScreenOrientation());
doLayout();
}
private final class MyPlaybackEventListener implements PlaybackEventListener {
private void updateLog(String prompt){
System.out.println(prompt);
};
@Override
public void onBuffering(boolean arg0) {
updateLog("onBuffering(): " + String.valueOf(arg0));
}
@Override
public void onPaused() {
updateLog("onPaused()");
}
@Override
public void onPlaying() {
updateLog("onPlaying()");
}
@Override
public void onSeekTo(int arg0) {
updateLog("onSeekTo(): " + String.valueOf(arg0));
}
@Override
public void onStopped() {
player.loadVideo("avP5d16wEp0");
player.cueVideo("avP5d16wEp0");
player.play();
updateLog("onStopped()");
}
}
}
最佳答案
我搜索了那个主题,我发现没有正式的方式,也不会根据this page在谷歌代码上。
在其中他们建议您创建一个播放器。
隐藏播放器。
使播放器静音。
使用您的视频 ID 和可选的偏移量调用 seekTo()。
等待状态变为“正在播放”。
按暂停。
调用 seekTo(originalOffset, false)。
取消播放器静音。
显示播放器。 (或其他)。
它可能无法满足您的需要,但也许您可以使用此方法更改实现目标所需的内容。
