Android - 更改 READ_PHONE_STATE 权限请求消息
Android - Change READ_PHONE_STATE permission request message
我正在使用 Android Marshmallow READ_PHONE_STATE 权限，我想更改权限请求中显示的文本。
默认显示：
Allow [App name] to make and manage phone calls?
但我正在使用它来获取 device id 和 sim serial number，所以我认为最好更改请求消息。有谁知道怎么做（一些特殊功能什么的）？
或者我只需要为此实现一个独立的 Dialog？
非常感谢。
不，您不能更改对话框中的文本。它在系统中默认实现。在请求许可之前，您可以提供有关许可的简要说明。这样用户就会确切地知道你要用它做什么。
Request Permissions
If your app needs a dangerous permission that was listed in the app
manifest, it must ask the user to grant the permission. Android
provides several methods you can use to request a permission. Calling
these methods brings up a standard Android dialog, which you cannot
customize.
Explain why the app needs permissions
In some circumstances, you might want to help the user understand why
your app needs a permission. For example, if a user launches a
photography app, the user probably won't be surprised that the app
asks for permission to use the camera, but the user might not
understand why the app wants access to the user's location or
contacts. Before you request a permission, you should consider
providing an explanation to the user. Keep in mind that you don't want
to overwhelm the user with explanations; if you provide too many
explanations, the user might find the app frustrating and remove it.
One approach you might use is to provide an explanation only if the
user has already turned down that permission request. If a user keeps
trying to use functionality that requires a permission, but keeps
turning down the permission request, that probably shows that the user
doesn't understand why the app needs the permission to provide that
functionality. In a situation like that, it's probably a good idea to
show an explanation.
To help find situations where the user might need an explanation,
Android provides a utiltity method,
shouldShowRequestPermissionRationale(). This method returns true if
the app has requested this permission previously and the user denied
the request.
