Activity调用运行时间权限变黑
Activity becomes black while calling the run time permissions
我想调用 运行 时间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，如果在对话框上单击允许或拒绝，activity 会变黑并完成。当我调试应用程序时，它不会在单击允许或拒绝后转到 onRequestPermissionsResult 方法。
如果权限被接受，我也会调用联系 Intent。我想在与 selected 联系人列表相同的 activity 中显示这些内容。因此，为此我有一个列表并将联系人添加到列表 onActivitResult 方法中。
但是如果我 select 来自联系人的一些联系人，那么 activity 也会完成。它不会转到 onActivityResult 方法。

奇怪的是，同样的代码以前工作正常。对于旧版本。我也尝试将相同的 activity 旧版本复制到新版本，但仍然不起作用。
没弄错。
有人可以帮忙吗？谢谢..
替换requestPermissions(new String[]{Manifest.permission.READ_CONTACTS}, PERMISSIONS_REQUEST_READ_CONTACTS);
和ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS}, PERMISSIONS_REQUEST_READ_CONTACTS);
确保您没有在 AndroidMenifest.xml 的 activity 声明中输入 android:noHistory=true 属性。
