Xml code if you copy directly from the Internet, but no local com.szectech.videoplayer.VideoPlayerActivity.view.MyGrid this class, definitely the wrong one.

I suggest you first achieve a detection method is correct, and then transplanted into the right inner class with the outer class.

That MyGrid originally written outside class, you can, and what methods are right. Now use the data in an activity, turning it into an internal class, now I just do not know how to use the xml inside an inner class.

Element type "com.szectech.videoplayer.VideoPlayerActivity.view" must be followed by either attribute specifications, ">" or "/>".
But behind MyGrid plus />, still prompt.

Only static class or method can be referenced externally.

Since the need is static class, and you say you want to use this class to Activity data also needs to be called a static object, if this object is defined in the Activity inside, that you give it, not because Activity defined as Static's.

That should be the wording of the controls, get hold of a separate document it, but also to other people to use. Transplantation is also convenient
