Uri uri = Uri.parse("https://pic4.zhimg.com/03b2d57be62b30f158f48f388c8f3f33_b.png");
        SimpleDraweeView commonImageView = (SimpleDraweeView) findViewById(R.id.commonImageView);
        commonImageView.setImageURI(uri);

        SimpleDraweeView circleImageView = (SimpleDraweeView) findViewById(R.id.circleImageView);
        circleImageView.setImageURI(uri);

        SimpleDraweeView roundedImageView = (SimpleDraweeView) findViewById(R.id.roundedImageView);
        roundedImageView.setImageURI(uri);
