[SOLVED] How to use an android accessibility service to detect which view the user touched?

How to use an android accessibility service to detect which view the user touched?

There's something that android TalkBack does that I want to do too. Specifically it's to identify the view that the user touched. I made this so far:

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
    if (event.getEventType() == AccessibilityEvent.TYPE_VIEW_CLICKED) {

        //This only shows the package of the activity that the view is in, I want to identify the view itself
        Toast.makeText(this, "" + event.getSource().getPackageName(), Toast.LENGTH_LONG).show();
    }
}

Solution

You can get the view's id, but I think you can only access the AccessibilityNodeInfo associated with the view - I don't think you have access to the view itself. You can check the docs for more information on this.

    // kotlin code
    event.source.viewIdResourceName
    // or
    findFocusedViewInfo().viewIdResourceName

According to the docs:

Gets the fully qualified resource name of the source view's id.

Note: The primary usage of this API is for UI test automation and in order to report the source view id of an AccessibilityNodeInfo the client has to set the AccessibilityServiceInfo#FLAG_REPORT_VIEW_IDS flag when configuring the AccessibilityService.
