[SOLUTION]
请修改
alps\packages\apps\gallery2\src\com\android\gallery3d\app\MoviePlayer.java中以下方法，
1. private static boolean isMediaKey(int keyCode) {
return keyCode == KeyEvent.KEYCODE_HEADSETHOOK
keyCode == KeyEvent.KEYCODE_MEDIA_FAST_FORWARD || /////// add this line.
keyCode == KeyEvent.KEYCODE_MEDIA_REWIND || ///////add this line.
keyCode == KeyEvent.KEYCODE_MEDIA_PREVIOUS ||
keyCode == KeyEvent.KEYCODE_MEDIA_NEXT ||
keyCode == KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE ||
keyCode == KeyEvent.KEYCODE_MEDIA_PLAY ||
keyCode == KeyEvent.KEYCODE_MEDIA_PAUSE;
}
2. 在onKeyDown() switch语句里增加一个case：
public boolean onKeyDown(int keyCode, KeyEvent event) {
.....
.....
case KeyEvent.KEYCODE_MEDIA_NEXT:
// /M:modify for slidevideo
if (！(mActivityContext instanceof MovieActivity)) {
return false;
}
if (((MovieActivity) mActivityContext).mMovieList == null) {
return false;
}
mPlayerExt.startNextVideo(((MovieActivity) mActivityContext).mMovieList
.getNext(mMovieItem));
return true;
case KEYCODE_MEDIA_FAST_FORWARD: ///////add this case
case KEYCODE_MEDIA_REWIND: ///////add this case
return true;
}
return false;
}
