我想调用运行时权限以在单击某些视图时读取联系人。所以我检查应用程序是否有权限，如果没有请求权限。但是，当请求对话框出现时，如果单击对话框上的允许或拒绝，活动将变黑并完成。当我调试应用程序时，单击允许或拒绝后它不会转到 onRequestPermissionsResult 方法。
如果权限被接受，我也会打电话给联系人 Intent。我想在与选定联系人列表相同的活动中显示这些。因此，为此我有一个列表并将联系人添加到列表 onActivitResult 方法中。
但是为此，如果我从联系人中选择一些联系人，活动就会完成。它不会转到 onActivityResult 方法。

奇怪的是，相同的代码以前可以正常工作。对于旧版本。我也尝试将旧版本的相同活动复制到新版本，但它仍然不起作用。
不明白怎么回事。
有人可以帮忙吗？谢谢..
