如何选择要用作“个人资料图片”的图像？

Question

您好，我有一个时间表应用程序，它有一个主菜单。我想要一个按钮，上面写着“选择图像”或类似的东西，所以当用户点击它时，他会进入他的画廊并选择照片，然后它会保存在我创建的时间表应用程序中。我希望有人可以帮助我，因为我在互联网上找到的唯一信息是我应该使用 android.intent.action.PICK？提前致谢

更新： 我这样做了，然后现在单击按钮加载图库（效果很好）。一旦我选择了一张图片，它就会显示“不幸的是，时间表已停止”。怎么了。这是代码。

假设它是一个社交应用程序，那么我建议使用this 教程或this SO question 来导入图片，然后将其保存在远程数据库中。
