问题
I am using a navigation drawer plus a tablayout. I have a video in my tab which was not visible at first, but I can hear the sound. Once I set
video_view.setZOrderOnTop(true);
and I can also see the video, but this causes an issue with navigation drawer.
When I slide it, the video doesn't hide behind the navigation drawer as do all other elements.
If I don't use
video_view.setZOrderOnTop(true);
then my drawer is works fine.

TabFragment.java
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View view = inflater.inflate(R.layout.tab_fragment, container, false);
VideoView video_player_view = (VideoView) view.findViewById(R.id.video_player_view);
video_player_view.setVideoURI("videourl");
video_player_view.setZOrderOnTop(true);
video_player_view.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mp) {
video_player_view.start();
}
});
return view;
}
So can Anyone guide me with an alternative for that.
回答1:
@Atula I suggest you a simple solution for this....This is work Perfect
I attach the screenshot working properly....
Try this
Used this
video_player_view.setZOrderMediaOverlay(true);
Instead Of
video_view.setZOrderOnTop(true);
回答2:
When you setZOrderOnTop(true) it will be on top of other Layout. In fact it Control whether the surface view's surface is placed on top of it window [see more].
I have a video in my tab which was not visible at first but I can hear sound.
Based on your comment you put other Layout on VideoView so you can't see VideoView But you hear the sound.
By turning Layout bound in phone:
Setting-> developer option -> show Layout bound
You can see what's going on in your Layouts. I guess you can't see VideoView because of those match_parents in your layout_height double check them ( e.g: put 50dp for each of them) and your problem will be fixed.
Also make root Layout match_parent instead of wrap_content. it's not solve the problem but its much better.

After a few comments, the OP wanted to see some code.
Ok, let's try something like this:
private DrawerLayout drawer;
private ActionBarDrawerToggle toggle;
protected void onResume() {
drawer.addDrawerListener(toggle);
toggle.syncState();
}
protected void onPause() {
drawer.removeDrawerListener(toggle);
toggle.syncState();
}
protected void onCreate(Bundle saveInstanceState) {
toggle = new ActionBarDrawerToggle(this, drawer,
toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) {
public void onDrawerClosed(View view) {
Log.d(TAG, "--> ActionBarDrawerToggle::onDrawerClosed
(view=" + view + ")");
syncActionBarArrowState();
//call videoView.setZOrderOnTop(true) so it's over everything
}
public void onDrawerOpened(View drawerView) {
Log.d(TAG, "--> ActionBarDrawerToggle::onDrawerOpened
(drawerView=" + drawerView + ")");
toggle.setDrawerIndicatorEnabled(true);
//call videoView.setZOrderOnTop(false) so it's NOT over the drawer
}
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, 0);
//call videoView.setZOrderOnTop(false)
//so it's not over the drawer being pulled out
}
};
}
回答4:
Did you try to use TextureView instead VideoView?
ViedoView is well known as bug prone view.
I wrote frame-video-view which (among other things) simplifies using TextureView as a video player.
