     * Creates a {@link ViewStructure} for a "standard" view.

     *

     * @hide

     * <p>This method should be called after a visible view is laid out; the view then must populate

     * the structure and pass it to {@link #notifyViewAppeared(ViewStructure)}.

     *

     * <b>Note: </b>views that manage a virtual structure under this view must populate just the

     * node representing this view and return right away, then asynchronously report (not

     * necessarily in the UI thread) when the children nodes appear, disappear or have their text

     * changed by calling {@link ContentCaptureSession#notifyViewAppeared(ViewStructure)},

     * {@link ContentCaptureSession#notifyViewDisappeared(AutofillId)}, and

     * {@link ContentCaptureSession#notifyViewTextChanged(AutofillId, CharSequence)} respectively.

     * The structure for the a child must be created using

     * {@link ContentCaptureSession#newVirtualViewStructure(AutofillId, long)}, and the

     * {@code autofillId} for a child can be obtained either through

     * {@code childStructure.getAutofillId()} or

     * {@link ContentCaptureSession#newAutofillId(AutofillId, long)}.

     *

     * <p>When the virtual view hierarchy represents a web page, you should also:

     *

     * <ul>

     * <li>Call {@link ContentCaptureManager#getContentCaptureConditions()} to infer content capture

     * events should be generate for that URL.

     * <li>Create a new {@link ContentCaptureSession} child for every HTML element that renders a

     * new URL (like an {@code IFRAME}) and use that session to notify events from that subtree.

     * </ul>

     *

     * <p><b>Note: </b>the following methods of the {@code structure} will be ignored:

     * <ul>

     * <li>{@link ViewStructure#setChildCount(int)}

     * <li>{@link ViewStructure#addChildCount(int)}

     * <li>{@link ViewStructure#getChildCount()}

     * <li>{@link ViewStructure#newChild(int)}

     * <li>{@link ViewStructure#asyncNewChild(int)}

     * <li>{@link ViewStructure#asyncCommit()}

     * <li>{@link ViewStructure#setWebDomain(String)}

     * <li>{@link ViewStructure#newHtmlInfoBuilder(String)}

     * <li>{@link ViewStructure#setHtmlInfo(android.view.ViewStructure.HtmlInfo)}

     * <li>{@link ViewStructure#setDataIsSensitive(boolean)}

     * <li>{@link ViewStructure#setAlpha(float)}

     * <li>{@link ViewStructure#setElevation(float)}

     * <li>{@link ViewStructure#setTransformation(android.graphics.Matrix)}

     * </ul>
