## Fields

### CREATOR

Added in [API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

<br />

<br />

## Public methods

### describeContents

Added in [API level 9](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` |

### getDevice

Added in [API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public final InputDevice getDevice ()
```

Gets the device that this event came from.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/view/InputDevice` | The device, or null if unknown. <br /> |

### getDeviceId

Added in [API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public abstract int getDeviceId ()
```

Gets the id for the device that this event came from. An id of zero indicates that the event didn't come from a physical device and maps to the default keymap. The other numbers are arbitrary and you shouldn't depend on the values.

<br />

| Returns ||
|---|---|
| `int` | The device id. <br /> |

**See also:**

### getEventTime

Added in [API level 16](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public abstract long getEventTime ()
```

<br />

| Returns ||
|---|---|
| `long` | Returns the time this event occurred, in the `https://developer.android.com/reference/android/os/SystemClock#uptimeMillis()` time base. <br /> |

### getSource

Added in [API level 9](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public abstract int getSource ()
```

Gets the source of the event.

<br />

| Returns ||
|---|---|
| `int` | The event source or `https://developer.android.com/reference/android/view/InputDevice#SOURCE_UNKNOWN` if unknown. <br /> |

**See also:**

### isFromSource

Added in [API level 18](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean isFromSource (int source)
```

Determines whether the event is from the given source.

<br />

| Parameters ||
|---|---|
| `source` | `int`: The input source to check against. This can be a specific device type, such as `https://developer.android.com/reference/android/view/InputDevice#SOURCE_TOUCH_NAVIGATION`, or a more generic device class, such as `https://developer.android.com/reference/android/view/InputDevice#SOURCE_CLASS_POINTER`. <br /> |

| Returns ||
|---|---|
| `boolean` | Whether the event is from the given source. <br /> |
