图库应用程序不接受图像的URL作为Intent的一部分.您需要先保存图像.然后，您可以使用以下内容启动默认的图像查看器:
Gallery application does not accept URL for an image as part of the Intent. You need to save the image first. Then you can launch the default image viewer with something like this:
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("file://" + "/sdcard/test.jpg"), "image/*");
startActivity(intent);
