I have created a widget that is an extension of SurfaceView (very similar to [VideoView][1]) and I am working on a feature to stretch the video fully across the device screen when certain action is taken. I've looked at onMeasure function of VideoView and re-wrote it this way:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    if (mStretchVideo) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    } else {
        int width = getDefaultSize(mVideoWidth, widthMeasureSpec);
        int height = getDefaultSize(mVideoHeight, heightMeasureSpec);
        if (mVideoWidth > 0 && mVideoHeight > 0) {
            if (mVideoWidth * height > width * mVideoHeight) {
                height = width * mVideoHeight / mVideoWidth;
            } else if (mVideoWidth * height < width * mVideoHeight) {
                width = height * mVideoWidth / mVideoHeight;
            }
        }
        setMeasuredDimension(width, height);
    }
}

This seems to work fine if I completely stop the video and start playing again. Now I am trying to force the refresh of this SurfaceView after setting the stretch flag so that the video gets stretched while it is playing, but I couldn't figure out how to force a refresh on SurfaceView. I tried android.view.View.invalidate(), android.view.View.refreshDrawableState() and calling android.view.View.measure(int, int) directly with different combinations but did not get any success. Any ideas?
