- 语法:
<permission-tree android:icon="drawable resource" android:label="string resource" android:name="string" />
- 包含于:
<manifest>
- 说明:
- 声明权限树的基名。应用拥有树中所有名称的所有权。它可以通过调用
PackageManager.addPermission()
动态地向树中添加新权限。 树中的名称由句点(“.
”)分隔。例如,如果基名为com.example.project.taxes
,则可能会添加如下权限:com.example.project.taxes.CALCULATE
com.example.project.taxes.deductions.STORE_RECEIPTS
com.example.project.taxes.deductions.ACCESS_RECORDS
此元素并不声明权限本身,而只声明可以放置权限的命名空间。如需详细了解如何声明权限,请参阅

The application takes\n ownership of all names within the tree. It can dynamically add new permissions\n to the tree by calling [PackageManager.addPermission()](/reference/android/content/pm/PackageManager#addPermission(android.content.pm.PermissionInfo)).\n Names within the tree are separated by\n periods ('`.`'). For example, if the base name is\n `com.example.project.taxes`, permissions like the following might be\n added:\n\n `com.example.project.taxes.CALCULATE`\n\n `com.example.project.taxes.deductions.STORE_RECEIPTS`\n\n `com.example.project.taxes.deductions.ACCESS_RECORDS`\n\n\n This element doesn't declare a permission itself, only a\n namespace in which permissions can be placed. For more information about declaring permissions, see the\n [\u003cpermission\u003e](/guide/topics/manifest/permission-element)\n element.\n\nattributes:\n:\n\n `android:icon`\n : An icon representing all the permissions in the tree. This attribute\n must be set as a reference to a drawable resource containing the image\n definition.\n\n `android:label`\n : A user-readable name for the group. As a convenience, the label\n can be directly set as a raw string during development. However,\n when the application is ready to be published, set it as a\n reference to a string resource, so that it can be localized like other\n strings in the user interface.\n\n `android:name`\n : The name at the base of the permission tree. It serves as\n a prefix to all permission names in the tree. Use Java-style scoping\n so that the name is unique. The name must have more than\n two period-separated segments in its path. For example,\n `com.example.base` is OK, but `com.example` isn't.\n\nintroduced in:\n: API level 1\n\nsee also:\n: [\u003cpermission\u003e](/guide/topics/manifest/permission-element)\n\n [\u003cpermission-group\u003e](/guide/topics/manifest/permission-group-element)\n\n [\u003cuses-permission\u003e](/guide/topics/manifest/uses-permission-element)"]]
