} 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 ();

ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));

The method for extracting videoid from a URL is as follows
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 "";
}
Because this project in the same fragment put a lot of such video playback control, so in order to unify their pause, destroy operations, here using a ArrayList for maintenance
When switching to other fragment or when new activity is pressed to the top, pause WebView playback, fragment the total OnPause method:
@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 ();
There is also a need to allow fragment to release WebView resources at the time of destruction as follows:
@Override
public void OnDestroy () {
Super.ondestroy ();
if (playerviewlist!=null) {
for (Youtubeplayerview v:playerviewlist) {
if (v!=null) {
V.ondestroy ();
}
}
}
}
Turn off full screen code when the return button is pressed
@Override
public void onbackpressed () {
Boolean isclose = Currentjournalfragment.closefullscreen ();
if (isclose) {
Return
}
} This fragment Closefullscreen method is as follows
public Boolean closefullscreen () {
if (mcustomview!=null && mcustomviewcallback!=null) {
Mwebchromeclient.onhidecustomview ();
return true;
}
return false;
}
