所选画廊图像未显示在第三个活动中
[英]Selected gallery image does not show in the third activity
问题描述
我正在创建一个应用程序，该应用程序授予用户对 select 的权限，这是第一个活动中来自画廊的图像，然后我想将其发送到“第三个和第四个活动”等等..，现在问题是我有一个加载活动是“第二个活动”，我用来将所选图像发送到多个活动的方法是绕过它们的 URI。 问题是，用户选择的图片正在第二个活动中显示，但是当我将URI's从第二个活动传递到第三个、第四个等等时，图片没有显示。 首先我认为我在传递 URI 时犯了一个错误，所以我在第三个活动中发送了一条 Toast 消息来测试我是否收到了 Uri，我收到了 Uri 地址，但我不知道为什么我不能拥有 Uri转换为 bitmap 和图像。 我已经被这个问题困扰了将近 2 周，我的一个朋友建议创建多个片段而不是多个活动，但我对制作片段并使其工作有点菜鸟。
我的问题是：
1-除了制作多个片段还有其他方法吗？ 如果没有那么如何通过我的代码使其工作，请阻止将我发送到 android.developer 网站链接。
2-如何通过 URI 或发送 bitmap 使图片显示在第三个和第四个活动中，如果是，那么如何修改我的代码？ 因为我在谷歌上找到的方法既没有帮助我，也没有为我的代码工作。
我的代码：
