问题描述
我看过很多关于这个的帖子，看起来下面的代码应该可以工作.我已经创建了一个 SD 卡映像并将其添加到模拟器(并且工作正常).
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
//intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1);
它确实启动并允许选择图像，但是当我单击图像时，一切都会退出并且模拟器返回到主屏幕，而不是返回到我的应用程序.我的 onActivityResult 也从未被调用.
我错过了什么?
推荐答案
我发现了我的问题.我正在从一个子活动启动图库，而该子活动 Intent 具有标志 FLAG_ACTIVITY_NO_HISTORY，这阻止了回调返回到该活动.
谢谢.

使用以下意图:
Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
intent.setType("image/*");
intent.putExtra("return-data", true);
startActivityForResult(intent, 1);
问题描述
I have seen a lot of posts about this, and it seems like the code below should work. I have created an SD Card image and added it to the emulator (and that works fine).
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
//intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1);
It does launch and allow selection of images, but when I click on an image, everything exits and the emulator returns to the home screen, not the back to my app. My onActivityResult is never called either.
What am I missing?
推荐答案
I found my issue. I was launching the gallery from a sub-activity and that sub activity Intent had the flag FLAG_ACTIVITY_NO_HISTORY which prevented the call back from going to that activity.
thanks.
