我像这样使用ImageManager尝试它:

    Uri icon = Games.Players.getCurrentPlayer(googleApiClient).getIconImageUri();

    ImageManager manager = ImageManager.create(this);
    manager.loadImage(photo, icon);

我还没有在LeaderboardScore上尝试过，但是我认为它是相同的.因为Uri格式是content://com.google.android.gms.games.background/blablabla

I haven't tried it yet on LeaderboardScore, but I think it will be same. since the Uri format is same content://com.google.android.gms.games.background/blablabla
