I'm currently running on the simulator so for now I'm just going to have it print to

问题 I am building an application to convert Latitude and Longitudes between various formats. My layout is complete but my current challenge is this: For the Degree values, as the user enters a value in EditText1, I want it to replicate in EditText2 as they are typing, real-time, character for character. I have beat myself up trying OnTouchListener, onKeyboardActionListener, etc. Later, I will perform calculations on the Minutes, Seconds, and decimal portions as they are typed in. Since the Degree

问题 Background So I read that often memory leaks within Swing applications originate from the use of various listeners (mouse, key, focus, etc). Essentially, because you register an object as a listener and forget to deregister the object, the notifier ends up holding onto the reference of the object, and leaks a bit of memory. I knew our application wasn't deregistering listeners and did a bit of research on potential solutions: I found one approach in dealing with the problem was the use of a

问题 I am looking for a jmeter graph listener that will output the subresults of a SamplerRequest object. I haven't found one yet and I'm very keen on getting it. 回答1: Old question, I know. Unfortunately, it appears that there are no JMeter graph listeners that will graph the results of sub results attached to a SampleResult.

问题 Is there any way of getting a list of registered listeners for an EventDispatcher ? I know that EventDispatcher has the hasEventListener method to tell you if any listeners are registered, but is there an easy way of interrogating the EventDispatcher to find out what the listeners are? One way I figured to do this was to subclass EventDispatcher to override the addEventListener method and store the listeners in a dictionary, but this feels clunky to me. Any ideas? 回答1: Ok, so it seems that
