ObservableInt

public class ObservableInt
extends BaseObservable implements Parcelable, Serializable

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


An observable class that holds a primitive int.

Observable field classes may be used instead of creating an Observable object. It can also create a calculated field, depending on other fields:

public class MyDataObject {
     public final ObservableField<String> name = new ObservableField<String>();
     public final ObservableInt age = new ObservableInt();
     public final ObservableInt birthdayCount = new ObservableInt(age) {
         @Override
         public int get() { return age.get() + 1; }
     };
 }
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. An parceled ObservableInt will lose its dependencies.

Public constructors

ObservableInt

ObservableInt (int value)

Creates an ObservableInt with the given initial value.

Parameters
value int: the initial value for the ObservableInt

ObservableInt

ObservableInt ()

Creates an ObservableInt with the initial value of 0.

ObservableInt

ObservableInt (Observable... dependencies)

Creates an ObservableInt that depends on dependencies. Typically, ObservableFields are passed as dependencies. When any dependency notifies changes, this ObservableInt also notifies a change.

Parameters
dependencies Observable: The Observables that this ObservableInt depends on.

Public methods

describeContents

int describeContents ()

Returns
int

get

int get ()

Returns
int the stored value.

set

void set (int value)

Set the stored value.

Parameters
value int: The new value

writeToParcel

void writeToParcel (Parcel dest, 
                int flags)

Parameters
dest Parcel

flags int
