If you want to block a worker thread and wait on something that's done
on the UI thread, you just need a synchronization point. The
java.util.concurrent package offers many tools to do that kind of
stuff. Here's an example using a CountDownLatch:
829 final CountDownLatch latch = new CountDownLatch(1);
830 final long[] duration = new long[1];
831
832 view.post(new Runnable() {
833 public void run() {
834 try {
835 T[] data = operation.pre();
836 long start = Debug.threadCpuTimeNanos();
837 operation.run(data);
838 duration[0] = Debug.threadCpuTimeNanos() - start;
839 operation.post(data);
840 } finally {
841 latch.countDown();
842 }
843 }
844 });
845
846 try {
847 latch.await(CAPTURE_TIMEOUT, TimeUnit.MILLISECONDS);
848 } catch (InterruptedException e) {
849 Log.w("View", "Could not complete the profiling of
the view " + view);
850 Thread.currentThread().interrupt();
851 return -1;
852 }
