Android MediaController intercepts all other touch

问题:

The top half of my app has a VideoView with a MediaController under it. The bottom half is an image with some buttons. While the MediaController is visible, the buttons below are not clickable. It's like while the MediaController is visible, it intercepts all other touch events, even if they are not within the bounds of the MediaController.

Any idea around that?

回答1:

You can check out my answer on overriding dispatchTouchEvent() to pass clicks through MediaController to an underlying Button, but I'm guessing there's something wrong with the way you use MediaController. Can you post your layout?

UPD: Actually, strike that. I've just taken a look at MediaController code and it turns out it creates a new Window for itself. That's why your clicks don't get dispatched — they're dispatched to another window. Also, as far as I can tell from the constructor code, if you inflate the MediaController via xml (i.e. use it in a layout file and then just find it by id from you code) — it won't create the extra Window. That's weird, but I'm sure they had reasons for that.

So, the solution is to either try to use MediaController in a layout file or go with CommonsWare's solution. Please, let me know how it goes in case you give the xml thing a try.

Do not use MediaController. Create your own controller UI that you pop up and display as needed. While this sample project may no longer completely work, as I have not touched in three years, it demonstrates having your own controller panel that pops up on a touch and then goes away.

Could you supply your VideoView instantiation code and the code you use to switch out the MediaPlayers?

In any case, I doubt this will work well because the VideoView instantiates its own MediaPlayer and uses it to play media. (see VideoView.java)

You would probably need to switch out the VideoView itself, or build a replacement for the VideoView using your own subclass of SurfaceView.
