AccessibilityNodeInfo

java.lang.Object

public class AccessibilityNodeInfo extends Object implements android.os.Parcelable

This class represents a node of the window content as well as actions that can be requested from its source. From the point of view of an {@link android.accessibilityservice.AccessibilityService} a window content is presented as tree of accessibility node info which may or may not map one-to-one to the view hierarchy. In other words, a custom view is free to report itself as a tree of accessibility node info.

Once an accessibility node info is delivered to an accessibility service it is made immutable and calling a state mutation method generates an error.

Please refer to {@link android.accessibilityservice.AccessibilityService} for details about how to obtain a handle to window content as a tree of accessibility node info as well as familiarizing with the security model.

Methods Summary
public void addAction(android.view.accessibility.AccessibilityNodeInfo$AccessibilityAction action)
Adds an action that can be performed on the node.
To add a standard action use the static constants on {@link AccessibilityAction}. To add a custom action create a new {@link AccessibilityAction} by passing in a resource id from your application as the action id and an optional label that describes the action. To override one of the standard actions use as the action id of a standard action id such as {@link #ACTION_CLICK} and an optional label that describes the action.

Note: Cannot be called from an {@link android.accessibilityservice.AccessibilityService}. This class is made immutable before being delivered to an AccessibilityService.
param
action The action.
throws
IllegalStateException If called from an AccessibilityService.
enforceNotSealed(); if (action == null) { return; } if (mActions == null) { mActions = new ArrayList<AccessibilityAction>(); } mActions.remove(action); mActions.add(action);
public void addAction(int action)
Adds an action that can be performed on the node.
Note: Cannot be called from an {@link android.accessibilityservice.AccessibilityService}. This class is made immutable before being delivered to an AccessibilityService.
param
action The action.
throws
IllegalStateException If called from an AccessibilityService.
throws
IllegalArgumentException If the argument is not one of the standard actions.
deprecated
This has been deprecated for {@link #addAction(AccessibilityAction)}
enforceNotSealed(); if ((action & ACTION_TYPE_MASK) != 0) { throw new IllegalArgumentException("Action is not a combination of the standard " + "actions: " + action); } addLegacyStandardActions(action);
public void addChild(android.view.View child)
Adds a child.
Note: Cannot be called from an {@link android.accessibilityservice.AccessibilityService}. This class is made immutable before being delivered to an AccessibilityService.
param
child The child.
throws
IllegalStateException If called from an AccessibilityService.
addChildInternal(child, UNDEFINED_ITEM_ID, true);
public void addChild(android.view.View root, int virtualDescendantId)
Adds a virtual child which is a descendant of the given root. If virtualDescendantId is {@link View#NO_ID} the root is added as a child.
A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report them selves as a tree of virtual views, thus conveying their logical structure.
param
root The root of the virtual subtree.
param
virtualDescendantId The id of the virtual child.
addChildInternal(root, virtualDescendantId, true);
private void addChildInternal(android.view.View root, int virtualDescendantId, boolean checked)

public void addChildUnchecked(android.view.View child)
Unchecked version of {@link #addChild(View)} that does not verify uniqueness. For framework use only.

For example, if the target application's package is "foo.bar" and the id resource name is "baz", the fully qualified resource id is "foo.bar:id/baz".
Note: It is a client responsibility to recycle the received info by calling {@link AccessibilityNodeInfo#recycle()} to avoid creating of multiple instances.

Note: The primary usage of this API is for UI test automation and in order to report the fully qualified view id if an {@link AccessibilityNodeInfo} the client has to set the {@link AccessibilityServiceInfo#FLAG_REPORT_VIEW_IDS} flag when configuring his {@link android.accessibilityservice.AccessibilityService}.

public void setSource(android.view.View root, int virtualDescendantId)
Sets the source to be a virtual descendant of the given root. If virtualDescendantId is {@link View#NO_ID} the root is set as the source.
A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report themselves as a tree of virtual views, thus conveying their logical structure.

public void setTraversalAfter(android.view.View view)
Sets the view whose node is visited after this one in accessibility traversal. A screen-reader must visit the content of the other node before the content of this one.
Note: Cannot be called from an {@link android.accessibilityservice.AccessibilityService}. This class is made immutable before being delivered to an AccessibilityService.
param
view The previous view.

#getTraversalAfter()
setTraversalAfter(view, UNDEFINED_ITEM_ID);
public void setTraversalAfter(android.view.View root, int virtualDescendantId)
Sets the node after which this one is visited in accessibility traversal. A screen-reader must visit the content of the other node before the content of this one. If virtualDescendantId equals to {@link View#NO_ID} the root is set as the predecessor.
A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report them selves as a tree of virtual views, thus conveying their logical structure.

Note: Cannot be called from an {@link android.accessibilityservice.AccessibilityService}. This class is made immutable before being delivered to an AccessibilityService.

public void setTraversalBefore(android.view.View view)
Sets the view before whose node this one should be visited during traversal. A screen-reader must visit the content of this node before the content of the one it precedes.
Note: Cannot be called from an {@link android.accessibilityservice.AccessibilityService}. This class is made immutable before being delivered to an AccessibilityService.
param
view The view providing the preceding node.
see
#getTraversalBefore()
setTraversalBefore(view, UNDEFINED_ITEM_ID);
public void setTraversalBefore(android.view.View root, int virtualDescendantId)
Sets the node before which this one is visited during traversal. A screen-reader must visit the content of this node before the content of the one it precedes. The successor is a virtual descendant of the given root. If virtualDescendantId equals to {@link View#NO_ID} the root is set as the successor.
A virtual descendant is an imaginary View that is reported as a part of the view hierarchy for accessibility purposes. This enables custom views that draw complex content to report them selves as a tree of virtual views, thus conveying their logical structure.

Note: Cannot be called from an {@link android.accessibilityservice.AccessibilityService}. This class is made immutable before being delivered to an AccessibilityService.
