Public Constructors

public ResultReceiver (Handler handler)

Create a new ResultReceive to receive results. Your onReceiveResult(int, Bundle) method will be called from the thread running handler if given, or from an arbitrary thread if null.

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 void send (int resultCode, Bundle resultData)

Deliver a result to this receiver. Will call onReceiveResult(int, Bundle), always asynchronously if the receiver has supplied a Handler in which to dispatch the result.

Parameters
resultCode Arbitrary result code to deliver, as defined by you.
resultData Any additional data provided by you.

public void writeToParcel (Parcel out, int flags)

Flatten this object in to a Parcel.

Parameters
out 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.

Protected Methods

protected void onReceiveResult (int resultCode, Bundle resultData)

Override to receive results delivered to this object.

Parameters
resultCode Arbitrary result code delivered by the sender, as defined by the sender.
resultData Any additional data provided by the sender.
