ObservableFloat

public class ObservableFloat
extends BaseObservable implements Parcelable, Serializable

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


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.

Summary

Inherited constants

From interface android.os.Parcelable

Fields

public static final Creator<ObservableFloat> CREATOR

Public constructors

ObservableFloat(float value)

Creates an ObservableFloat with the given initial value.

ObservableFloat()

Creates an ObservableFloat with the initial value of 0f.

Public methods

int describeContents()

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

float get()
void set(float value)

Fields

CREATOR

Creator<ObservableFloat> CREATOR

Public constructors

ObservableFloat

ObservableFloat (float value)

Creates an ObservableFloat with the given initial value.

Parameters
value float: the initial value for the ObservableFloat

ObservableFloat

ObservableFloat ()

Creates an ObservableFloat with the initial value of 0f.

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

float get ()

Returns
float the stored value.

set

void set (float value)

Set the stored value.

Parameters
value float

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.
