你需要使用video.layout(左,上,右,下); 为了你的目的.

你能尝试一下吗？

public boolean onOptionsItemSelected(MenuItem item)
{
    switch(item.getItemId())
    {
        case SMALL:
            // YOU CAN CREATE LEFT, TOP, RIGHT, BOTTOM FOR YOUR VIEW AND SET.
            int left = video.getLeft();
            int top = video.getTop();
            int right = left + (width / 2);
            int botton = top + (height / 2);
            video.layout(left, top, right, bottom);
            Toast.makeText(getApplicationContext(), "Small called", Toast.LENGTH_LONG).show();
            break;
        case DEFAULT:
                // YOU CAN CREATE LEFT, TOP, RIGHT, BOTTOM FOR YOUR VIEW AND SET.
            int left = video.getLeft();
            int top = video.getTop();
            int right = left + (width);
            int botton = top + (height);
            video.layout(left, top, right, bottom);
                Toast.makeText(getApplicationContext(), "Default called", Toast.LENGTH_LONG).show();
            break;
    }   
    return super.onOptionsItemSelected(item);
}

我认为它应该有效.
