ObservableFloat

extends BaseObservable
implements Parcelable Serializable

Class Overview

An observable class that holds a primitive float.

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

public class MyDataObject {
     public final ObservableFloat temperature = new ObservableFloat();
 }
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.

Fields

public static final Creator<ObservableFloat> CREATOR

Public Constructors

public ObservableFloat (float value)

Creates an ObservableFloat with the given initial value.

Parameters
value the initial value for the ObservableFloat

public ObservableFloat ()

Creates an ObservableFloat with the initial value of 0f.

Public Methods

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns
  • a bitmask indicating the set of special object types marshalled by the Parcelable.

public float get ()

Returns
  • the stored value.

public void set (float value)

Set the stored value.

public void writeToParcel (Parcel dest, int flags)

Flatten this object in to a Parcel.

Parameters
dest The Parcel in which the object should be written.
flags Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE.
