Android：在标准图库中查看远程图像

Question

我正在使用应显示使用标准android画廊通过HTTP定位的图像的应用程序，但gallery不会显示该图像。

当前代码：

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(model.get_media_URL()), "image/jpeg");
startActivity(intent);

错误：

如果我改用以下代码：

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(Uri.parse(model.get_media_URL()));
startActivity(intent);

它可以工作，但是会打开Internet浏览器而不是标准画廊，

谢谢！

Answer 1

Intent intentBrowseFiles = new Intent(Intent.ACTION_GET_CONTENT);
intentBrowseFiles.setDataAndType(Uri.parse(model.get_media_URL()), "image/*");
intentBrowseFiles.setFlag(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intentBrowseFiles);
