我正在尝试通过我们的应用程序使用可访问性来单击“允许设置”。我已经查看了AccessibilityNode，但在TextView中看不到任何可交互的内容。这是节点的输出：
Event Type: TYPE_WINDOW_CONTENT_CHANGED com.google.android.permissioncontroller android.widget.FrameLayout
Source:
0 | class name: android.widget.FrameLayout text: null content description: null input type 0 actions: ACTION_SELECT, ACTION_CLEAR_SELECTION, ACTION_ACCESSIBILITY_FOCUS, ACTION_SHOW_ON_SCREEN

TextView只有很少的可用操作。据我所知，我尝试了可用的操作，但没有成功。
我还探讨了直接意图用于“允许设置”部分的想法，但目前还没有。我们的应用要求位置始终保持打开状态。
ClickableSpans从Android O开始传递到可访问性。您可以在文本中找到ClickableSpans并调用onClick。然后，系统将确保在应用程序过程中调用了原始跨度的onClick方法。
如果使用AccessibilityNodeInfoCompat，则将其反向移植，但该应用程序还必须已调用ViewCompat＃enableAccessibleClickableSpanSupport（view）。
