I have a time consuming task i don't want to run in the main UI thread, so
i
do the following (pseudo-code):
onClick:
getresults()
public void getresults():
TextView tv;
String result = dolongjob()
tv.setText(result);
public void dolongjob():
new Thread(){
public void run(){
// Some time consuming task
// Which builds a String.
}
}
Now as shown the i want the dolongjob, which builds a string, to return the
calculated string
to the caller (getresults), but since Thread->run() has to be returning void
it can't return the
calculated string.
I know i have to be working with CountDownLatch.await to ensure 'tv' is only
updated when the
results are known, but how can i return a value which is calculated in a
Thread?
