ActivityForResult 仅获取 JPEG
大家好，
我正在编写一个小型社交网络应用程序，我包含的功能之一是能够将图片上传到服务器以用作您的“个人资料图片”。我通过启动 ActivityForResult 来实现此目的：
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
System.out.println("STARTED IT HERE");
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
这让用户可以选择从接受此 Intent 的任何内容（我的 Gallery 和 Astro）获取图像 URI。我有处理所有事情的代码，并且一切正常（除了当我从图库中选择图像时出现 outOfMemoryException 问题，但那是针对不同的主题:)）。我的问题是，我该怎么说：
intent.setType("image/jpeg");
因为我只希望用户上传 jpeg？
非常感谢！
Hey everybody,
I'm writing a small social networking app, and one of the features I included is the ability to upload a picture to a server to be used as your "profile picture". I did this by starting an ActivityForResult with this intent:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
System.out.println("STARTED IT HERE");
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
This lets the user choose between getting an image URI from whatever accepts this Intent (Gallery and Astro by me). I have code that handles everything, and it all works (other than an issue with an outOfMemoryException when I pick the image from the gallery, but that's for a different topic :) ). My question is, how can I say something like:
intent.setType("image/jpeg");
because I only want users to upload jpegs?
Thanks so much in advance!!!

您只是想限制人们选择 jpg 样式文件？
这个怎么样？
Intent pickPhoto = new Intent(Intent.ACTION_PICK);pickPhoto.setType("image/*.jpg");
抱歉必须编辑，我从应用程序中复制了错误的两行。上升了一行至高位。这就是我的意思。
You just want to limit people to picking jpg style files?
How about this?
Intent pickPhoto = new Intent(Intent.ACTION_PICK);pickPhoto.setType("image/*.jpg");
Sorry had to edit, I copied the wrong two lines from my app. Went one line to high. This is what I meant.
