ObservableBoolean

public class ObservableBoolean
extends BaseObservable implements Parcelable, Serializable

java.lang.Object
   ↳ android.databinding.BaseObservable
     ↳ android.databinding.ObservableBoolean


An observable class that holds a primitive boolean.

Observable field classes may be used instead of creating an Observable object:

public class MyDataObject {
     public final ObservableBoolean isAdult = new ObservableBoolean();
 }
Fields of this type should be declared final because bindings only detect changes in the field's value, not of the field itself.

This class is parcelable and serializable but callbacks are ignored when the object is parcelled / serialized. Unless you add custom callbacks, this will not be an issue because data binding framework always re-registers callbacks when the view is bound.

Public constructors

ObservableBoolean

ObservableBoolean (boolean value)

Creates an ObservableBoolean with the given initial value.

Parameters
value boolean: the initial value for the ObservableBoolean

ObservableBoolean

ObservableBoolean ()

Creates an ObservableBoolean with the initial value of false.

Public methods

describeContents

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.

get

boolean get ()

Returns
boolean the stored value.

set

void set (boolean value)

Set the stored value.

Parameters
value boolean

writeToParcel

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_WRITE_RETURN_VALUE.
