推荐答案

好了，这是code我用做这样的事情。也许你可以尝试一下：

Well, this is the code I'm using to do such thing. Maybe you can try it :

final Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");

intent.putExtra("crop", "true");

intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);

intent.putExtra("outputX", 400);
intent.putExtra("outputY", 400);
// Scale the image down to 400 x 400
intent.putExtra("scale", true);

intent.putExtra("windowTitle", "My_title");
    // You need to use a temporary file for cropping to work
    File tempFile = File.createTempFile("crop", "png",
              myActivity.getCacheDir());
mSavedUri = Uri.fromFile(tempFile);
intent.putExtra("output", mSavedUri);
intent.putExtra("outputFormat", "PNG");

profileActivity.startActivityForResult(intent, INTENT_PICK_PICTURE);

我想你必须 intent.setType（...）更改为 intent.setDataAndType（Uri.parse（机器人。资源：// ......），图像/ *）
