ViewStructure

ViewStructure

public ViewStructure ()

addChildCount

public abstract int addChildCount (int num)

Add to this view's child count. This increases the current child count by num children beyond what was last set by setChildCount(int) or addChildCount(int). The index at which the new child starts in the child array is returned.

asyncCommit

public abstract void asyncCommit ()

Call when done populating a ViewStructure returned by asyncNewChild(int).

asyncNewChild

public abstract ViewStructure asyncNewChild (int index)

Like newChild(int), but allows the caller to asynchronously populate the returned child. It can transfer the returned ViewStructure to another thread for it to build its content (and children etc). Once done, some thread must call asyncCommit() to tell the containing ViewStructure that the async population is done.

NOTE: you must pre-allocate space for the child first, by calling either addChildCount(int) or setChildCount(int).

clearCredentialManagerRequest

public void clearCredentialManagerRequest ()

Clears the credential request previously set through ViewStructure.setPendingCredentialRequest(GetCredentialRequest, OutcomeReceiver)

getAutofillId

public abstract AutofillId getAutofillId ()

Gets the AutofillId associated with this node.

getChildCount

public abstract int getChildCount ()

Return the child count as set by setChildCount(int).

getExtras

public abstract Bundle getExtras ()

Get extra data associated with this view structure; the returned Bundle is mutable, allowing you to view and modify its contents. Keys placed in the Bundle should use an appropriate namespace prefix (such as com.google.MY_KEY) to avoid conflicts.

getHint

public abstract CharSequence getHint ()

Retrieve the last hint set by setHint(CharSequence).

getPendingCredentialCallback

public OutcomeReceiver<GetCredentialResponse, GetCredentialException> getPendingCredentialCallback ()

Gets the callback associated with this node.

If null, no callback or request is associated with this node, and hence no CredentialManager request will be fired when this node is focused.

For details on how a request and callback can be set, see ViewStructure.setPendingCredentialRequest(GetCredentialRequest, OutcomeReceiver)

getPendingCredentialRequest

public GetCredentialRequest getPendingCredentialRequest ()

Gets the GetCredentialRequest associated with this node.

If null, no request is associated with this node, and hence no CredentialManager request will be fired when this node is focused.

For details on how a request and callback can be set, see ViewStructure.setPendingCredentialRequest(GetCredentialRequest, OutcomeReceiver)

getText

public abstract CharSequence getText ()

Retrieve the last setText(java.lang.CharSequence).

getTextSelectionEnd

public abstract int getTextSelectionEnd ()

Retrieve the last selection end set by setText(java.lang.CharSequence, int, int).

public abstract boolean hasExtras ()

Returns true if getExtras() has been used to create extra content.

newChild

public abstract ViewStructure newChild (int index)

Create a new child ViewStructure in this view, putting into the list of children at index.

setChildCount

public abstract void setChildCount (int num)

setClickable

public abstract void setClickable (boolean state)

setContextClickable

public abstract void setContextClickable (boolean state)

Set the context clickable state of this view, as per View.isContextClickable().

setDataIsSensitive

public abstract void setDataIsSensitive (boolean sensitive)

Sets whether the data on this node is sensitive; if it is, then its content (text, autofill value, etc..) is striped before calls to AutofillService.onFillRequest(android.service.autofill.FillRequest, android.os.CancellationSignal, android.service.autofill.FillCallback).

By default, all nodes are assumed to be sensitive, and only nodes that does not have PII (Personally Identifiable Information - sensitive data such as email addresses, credit card numbers, passwords, etc...) should be marked as non-sensitive; a good rule of thumb is to mark as non-sensitive nodes whose value were statically set from resources.

Notice that the content of even sensitive nodes are sent to the service (through the AutofillService.onSaveRequest(android.service.autofill.SaveRequest, android.service.autofill.SaveCallback) call) when the user consented to save thedata, so it is important to set the content of sensitive nodes as well, but mark them as sensitive.

Should only be set when the node is used for autofill purposes - it will be ignored when used for Assist.

Set the basic dimensions of this view.

setElevation

public abstract void setElevation (float elevation)
