@Override

public void handleMessage(Message msg) {

AsyncTaskResult result = (AsyncTaskResult) msg.obj;

switch (msg.what) {

case MESSAGE_POST_RESULT:

// There is only one result

result.mTask.finish(result.mData[0]);

break;

case MESSAGE_POST_PROGRESS:

result.mTask.onProgressUpdate(result.mData);

break;

case MESSAGE_POST_CANCEL:

result.mTask.onCancelled();

break;

}

}

}

private void finish(Result result) {

if (isCancelled()) result = null;

onPostExecute(result);

mStatus = Status.FINISHED;

}

再看

protected final void publishProgress(Progress... values) {

sHandler.obtainMessage(MESSAGE_POST_PROGRESS,

new AsyncTaskResult(this, values)).sendToTarget();

}
