在Fragment中初始化的代码
View youtubeView = LayoutInflater.from(journalActivity).inflate(R.layout.layout_youtube_player, null);
YoutubePlayerView youtubePlayerView = (YoutubePlayerView) youtubeView.findViewById(R.id.youtubePlayerView);
youtubePlayerView.setAutoPlayerHeight(journalActivity);
youtubePlayerView.initialize(videoID, new YoutubePlayerCallBack(youtubePlayerView), mWebChromeClient);
ll_journal.addView(youtubeView,ll_journal.getChildCount()-1);
上面提到的布局文件R.layout.layout_youtube_player如下
android:layout_
android:layout_
android:orientation="vertical">
android:id="@+id/youtubePlayerView"
android:layout_
android:layout_
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="10dp"/>
android:layout_
android:layout_
android:layout_gravity="top"
android:clickable="true"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_marginTop="10dp">
上面提到的WebChromeClient定义如下，用于控制全屏播放的
private WebChromeClient mWebChromeClient = new WebChromeClient(){
@Override
public View getVideoLoadingProgressView() {
LayoutInflater inflater = LayoutInflater.from(activity);
mVideoProgressView = inflater.inflate(R.layout.video_layout_loading, null);
return mVideoProgressView;
}
@Override
public void onShowCustomView(View view,
WebChromeClient.CustomViewCallback callback) {
// if a view already exists then immediately terminate the new one
if(journalActivity==null){
return;
}
if (mCustomView != null) {
onHideCustomView();
return;
}
// 1. Stash the current state
mCustomView = view;
mOriginalSystemUiVisibility = journalActivity.getWindow().getDecorView().getSystemUiVisibility();
mOriginalOrientation = journalActivity.getRequestedOrientation();
// 2. Stash the custom view callback
mCustomViewCallback = callback;
// 3. Add the custom view to the view hierarchy
FrameLayout decor = (FrameLayout) journalActivity.getWindow().getDecorView();
decor.addView(mCustomView, new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
if(mVideoFullScreenBack!=null){
mVideoFullScreenBack.setVisibility(View.VISIBLE);
}
// 4. Change the state of the window
activity.getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE |
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN |
View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
View.SYSTEM_UI_FLAG_FULLSCREEN |
View.SYSTEM_UI_FLAG_IMMERSIVE);
activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
@Override
public void onHideCustomView() {
if (journalActivity == null) {
return;
}
// 1. Remove the custom view
FrameLayout decor = (FrameLayout) journalActivity.getWindow().getDecorView();
decor.removeView(mCustomView);
mCustomView = null;
if(mVideoFullScreenBack!=null){
mVideoFullScreenBack.setVisibility(View.GONE);
}
// 2. Restore the state to it's original form
journalActivity.getWindow().getDecorView()
.setSystemUiVisibility(mOriginalSystemUiVisibility);
journalActivity.setRequestedOrientation(mOriginalOrientation);
// 3. Call the custom view callback
if(mCustomViewCallback!=null){
mCustomViewCallback.onCustomViewHidden();
mCustomViewCallback = null;
}
}
};
上面提到的R.layout.view_layout_loading布局文件如下,仅仅是一个progressBar当占位符用的
android:layout_
android:layout_
android:gravity="center"
android:orientation="vertical">
android:id="@android:id/progress"
style="?android:attr/progressBarStyleLarge"
android:layout_
android:layout_
android:layout_gravity="center"/>
从url中抽取VideoId的方法如下
private String parseIDfromVideoUrl(String videoUrl){
int startIndex = videoUrl.indexOf(VIDEO_ID_START);
if(startIndex != -1){
startIndex = startIndex + VIDEO_ID_START.length();
int endIndex = videoUrl.indexOf("?");
if(endIndex == -1){
endIndex = videoUrl.length();
}
if(startIndex < endIndex){
return videoUrl.substring(startIndex,endIndex);
}
}
return "";
}
因为本项目在同一个fragment中放了好多的这样的视频播放控件，所以为了统一他们暂停，销毁操作，这里使用了一个ArrayList进行维护
当切换到其他fragment或者有新的Activity压到上面的时候暂停WebView的播放，fragment总的onPause方法这么写：
@Override
public void onPause() {
if(playerViewList!=null){
for(YoutubePlayerView v : playerViewList){
if(v.getPlayerState() == YoutubePlayerView.STATE.PLAYING ){
v.pause();
}else if(v.getPlayerState() == YoutubePlayerView.STATE.BUFFERING){
v.stop();
}
}
}
super.onPause();
}还需要让fragment在销毁的时候释放WebView的资源如下：
@Override
public void onDestroy() {
super.onDestroy();
if(playerViewList!=null){
for(YoutubePlayerView v : playerViewList){
if(v!=null){
v.onDestroy();
}
}
}
}
在按下返回按钮时关闭全屏显示的代码
@Override
public void onBackPressed() {
boolean isClose = currentJournalFragment.closeFullScreen();
if(isClose){
&nbs
