Creator CREATOR ```

## Public constructors ### Gesture Added in[API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Gesture () ```

## Public methods ### addStroke Added in[API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public void addStroke (GestureStroke stroke) ``` Adds a stroke to the gesture.
### clone Added in[API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public Object clone () ``` Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object`x`, the expression: > > ``` > x.clone() != x > ``` will be true, and that the expression: > > ``` > x.clone().getClass() == x.getClass() > ``` will be`true`, but these are not absolute requirements. While it is typically the case that: > > ``` > x.clone().equals(x) > ``` will be`true`, this is not an absolute requirement. By convention, the returned object should be obtained by calling`super.clone`. If a class and all of its superclasses (except`Object`) obey this convention, it will be the case that`x.clone().getClass() == x.getClass()`. By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by`super.clone`before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by`super.clone`need to be modified.
| Returns || |--------------------------------------------------------------------|----------------------------------| | [Object](https://developer.android.com/reference/java/lang/Object) | a clone of this instance.
| ### describeContents Added in[API level 4](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[writeToParcel(android.os.Parcel, int)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)bit.
| Returns || |-------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

| ### getStrokesCount Added in[API level 4](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels) ``` public int getStrokesCount () ```
