问题描述

嘿，我正在android studio中设计一个应用程序.在其中我需要相机的许可.我在AndroidManifest.xml文件中包含了<uses-permission android:name="android.permission.CAMERA" /> .除棉花糖外，它在所有版本的android中均可正常运行.默认情况下如何获得相机许可?如果不可能的话，我该如何向用户询问?

Hey I am designing an app in android studio. In which i require permission of camera. I have included <uses-permission android:name="android.permission.CAMERA" /> in the the AndroidManifest.xml file. It is working properly in all versions of android except Marshmallow. How do I get camera permission by default? If not possible how do I ask it from user?

推荐答案

首先检查用户是否已授予权限:

First check if the user has granted the permission:

if (ContextCompat.checkSelfPermission(context, Manifest.permission.CAMERA)
    == PackageManager.PERMISSION_DENIED)

然后，您可以使用此请求用户:

Then, you could use this to request to the user:

ActivityCompat.requestPermissions(activity, new String[] {Manifest.permission.CAMERA}, requestCode);

在棉花糖中，它将出现在对话框中

And in Marshmallow, it will appear in a dialog
