## Fields

### CREATOR

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final Creator<AutofillId> CREATOR
```

<br />

<br />

## Public methods

### create

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static AutofillId create (View host, 
                int virtualId)
```

Creates an `https://developer.android.com/reference/android/view/autofill/AutofillId` with the virtual id.

This method is used by a `https://developer.android.com/reference/android/view/View` that contains the virtual view hierarchy. Use this
method to create the `https://developer.android.com/reference/android/view/autofill/AutofillId` for each virtual view.

<br />

| Parameters ||
|---|---|
| `host` | `View`: the view hosting the virtual view hierarchy which is used to show autofill suggestions. This value cannot be `null`. <br /> |
| `virtualId` | `int`: id identifying the virtual view inside the host view. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/view/autofill/AutofillId` | an `https://developer.android.com/reference/android/view/autofill/AutofillId` for the virtual view. This value cannot be `null`. <br /> |

### describeContents

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int describeContents ()
```

Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`,
the return value of this method must include the
`https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |

### equals

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object obj)
```

Indicates whether some other object is "equal to" this one.


The `equals` method implements an equivalence relation
on non-null object references:

- It is *reflexive*: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is *symmetric*: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is *transitive*: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is *consistent*: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.


An equivalence relation partitions the elements it operates on
into *equivalence classes*; all the members of an
equivalence class are equal to each other. Members of an
equivalence class are substitutable for each other, at least
for some purposes.

<br />

| Parameters ||
|---|---|
| `obj` | `Object`: This value may be `null`. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getAutofillVirtualId

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getAutofillVirtualId ()
```

Gets the virtual id. This is set if the view is a virtual view, most commonly set if the View
is of `https://developer.android.com/reference/android/webkit/WebView`.

<br />

| Returns ||
|---|---|
| `int` | <br /> |

### getSessionId

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getSessionId ()
```

Used to get the Session identifier associated with this AutofillId.

<br />

| Returns ||
|---|---|
| `int` | a non-zero integer if `https://developer.android.com/reference/android/view/autofill/AutofillId#isInAutofillSession()` returns true <br /> |

### getViewId

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getViewId ()
```

Returns the assigned unique identifier of this AutofillID.

See @link{android.view.View#getAutofillId()} for more information on
how this is generated for native Views.

<br />

| Returns ||
|---|---|
| `int` | <br /> |

### hashCode

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int hashCode ()
```

Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
`https://developer.android.com/reference/java/util/HashMap`.


The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

<br />

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### isInAutofillSession

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean isInAutofillSession ()
```

Checks if this node is generate as part of a `https://developer.android.com/reference/android/app/assist/AssistStructure`. This
will usually return true if it should be used by an autofill service provider, and false
otherwise.

<br />

| Returns ||
|---|---|
| `boolean` | <br /> |

### isVirtual

Added in [API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean isVirtual ()
```

Checks whether this AutofillId represents a virtual view.

<br />

| Returns ||
|---|---|
| `boolean` | <br /> |

### toString

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String toString ()
```

Returns a string representation of the object.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string representation of the object. <br /> |

### writeToParcel

Added in [API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void writeToParcel (Parcel parcel, 
                int flags)
```

Flatten this object in to a Parcel.

<br />

| Parameters ||
|---|---|
| `parcel` | `Parcel`: The Parcel in which the object should be written. This value cannot be `null`. <br /> |
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
