Public methods

describeContents

added in API level 21
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(Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int a bitmask indicating the set of special object types marshaled by this Parcelable object instance.

getIcon

added in API level 21
public Bitmap getIcon ()

Returns
Bitmap The icon that represents the current state of this task.

getLabel

added in API level 21
public String getLabel ()

Returns
String The label and description of the current state of this task.

getPrimaryColor

added in API level 21
public int getPrimaryColor ()

Returns
int The color override on the theme's primary color.

readFromParcel

added in API level 21
public void readFromParcel (Parcel source)

Parameters
source Parcel

toString

added in API level 21
public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Returns
String a string representation of the object.

writeToParcel

added in API level 21
public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest Parcel: The Parcel in which the object should be written.

flags int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
