I have a webview that's playing a video, and I want it to appear behind some other views, but I can't seem to make it happen. I've tried simply just sending the foreground views to the front with bringChildToFront(View v), but no cigar. Any thoughts?
Edit: Some more details: The webview plays a video using flash, and the webview is the size of the entire screen. I have some stuff I want to pop up in front of the video, but they only stay behind the video. They're definitely there, as they receive touch events and stuff, but just hidden away from view by the video.
Since the Flash player will essentially pre-empt any other views in the window, you'll just have to do one better over Flash: use another window on top of the main window.
Android allows you to do this by using the PopupWindow class.

I'm using YouTubePlayerView of YouTube Android Player API. I just want to get the center view of the video like this:
Is there anyway to do that ?
You can't crop a video while playing via the android youtube-player-api. You also can't hide any part of the video by overlaying another view on top of it or the player will throw UNAUTHORIZED_OVERLAY Error.
So if you ever try to hide the player by putting a View or two on either side then you can't. However there is one way to cover the YouTubePlayerView: Dialog and DialogFragment, you can put up either a Dialog or DialogFragment add some views and cover the video partially to give that special crop effect. From these two IMO DialogFragment is the better choice (you may feel differently).
Another way to crop the video would require complete change of player on your part. You'd have to switch to a WebView based player i.e. play your videos in a literal browser (there are lots of WebView-based players available on github). A WebView unlike YoutubePlayerView or YoutubePlayerFragment will not throw the nasty UNAUTHORIZED_OVERLAY Error. However you will see ads and the default player controls while the video is being loaded. I guess you might be able to hide the WebView or overlay another view on top of it while the video is loading and use the YouTube Data API to put a thumbnail on top, but I've never tried it.
I am using a YoutubeAndroidPlayerAPI in my Android App.
In my YouTubePlayerSupportFragment I am setting youtubePlayer.addFullscreenControlFlag(YouTubePlayer.FULLSCREEN_FLAG_CUSTOM_LAYOUT); so that I can change between Fullscreen without having to rebuffer each time I do so.
For that I removed the navigation bar please see my previous SO question about it. So now the player is playing fine. But somehow the touch events are passing down behind the player (i.e. to views behind youtube player) but Only when touch events are below the player's SeekBar (In FullScreen Mode).
Is there any workarounds to this problem?
Any one knows of any open issues regarding this issue?
Try adding android:clickable="true" to the top ViewGroup of your fragment's layout file.
I have an app that I'm working where in one activity I'm using a VideoView while setting the theme for that activity translucent (transparent) : android:theme="#android:style/Theme.Translucent.NoTitleBar.Fullscreen"
However I'm noticing odd behavior from the videoView - for a split second before the video starts playing (it's auto play) the frame where the videoView is itself transparent and you can see the activity behind it. For reference the activity in question has other elements to it and the video is framed.
Is there anyway to make this black or even a custom image that covers the frame before the video starts?
videoView.setBackgroundColor is buggy and actually changes the foreground color and keeps the frame that color while playing...
thanks for your time!
videoView.setZOrderOnTop(true);
SurfaceView (and VideoView as subclass) is placed behind the window by default. So you should call: videoView.setZOrderOnTop(true) if you want to place it on top (to make it non transparent).
You can cover the ViewView with another View and then as soon as video playing starts you can animate this View out, let's say quickly changing its alpha to 0.0.
Please read this response in other SO thread, i think it's the solution for this problem, at least it worked for me
Phone only with Android 4.0+ and no other third party libraries.
Application uses Navigation Tab of the ActionBar. One of the tab contains the stock VideoView control from ICS streaming live video from a source. I want to have the VideoView keep playing when user switch tabs to view information (call it InformationView).
On a tablet, I don't have this issue because the screen size is bigger and I make VideoView always on screen.
On a phone, screen is smaller therefore tab must be used.
I understand that VideoView probably depends on a visible surface in order to draw the video frame. When user switch tabs, the surface isn't available to VideoView therefore it automatically stops.
I can probably work around this by using a big scrollview that contains both InformationView and VideoView.
Is there any way to force it keep playing (maybe by drawing to an invisible surface) or is there a third party library that mimic the 'tab' behavior by using a giant scrollview so I don't have to write more code?
Note this isn't the same as multiple VideoViews problem which described here: One videoview blocked by another videoview
OK the solution is to hide the fragment that contains the VideoView when switching tabs, hence there is always a 'surface' video view can draw to.
You can custom VideoView same default but that's different you should control holder surface, oncreatSurface, onchangeSurface().
A better implementation of this concept would be not to use the stock VideoView widget, which is really just a marrying together of a SurfaceView and a MediaPlayer, but to divorce these two and use them individually. If your application controls the MediaPlayer directly, is can continue to play the audio track even after the surface disappears.
Making your Activity or Fragment one of the SurfaceHolder.Callback instances attached to the SurfaceView will allow you to know when the surface is or is not available for drawing. The MediaPlayer methods setDisplay() and setSurface() would be then used in your application to attach and detach the video surface when it becomes available in the view hierarchy per that callback.
You may also find the source of VideoView helpful (link) in coming up with your own implementation that accomplishes a similar goal.
My application has several pages of book. In some of page I am playing video using video view. I am checking if I have any video for that page. If yes, than I am making videoview visible and passing Uri. If not, I am making it gone.
Now the problem is, once i reached to that screen and then if I swipe left/right it's creating black window in every subsequent screen. Why?
I found solution. When you want to show video make videoView.setZOrderOnTop(false); and when you want to hide video view jusr make videoView.setZOrderOnTop(true);
