检测ui线程在Android上停滞的简单方法？

Question

I have taken over an Android project from a past employee and am wondering if there is an easy tool to use for profiling an Android application. I have a LinearLayout with a ProgressBar spinner inside of it. Now I am running a network call on a different thread while that spinner is showing. I use a translate animation to show the entire LinearLayout and when the network call returns on the other thread I hide the LinearLayout. Now this works great but I see that the spinner kind of stops spinning while it is showing. Now it kind of looks like if I interact with the screen, such as trying to scroll, the spinner will continue to spin. For a standard ProgressBar spinner do I need to set some command on the spinner to keep it spinning? Any information on this would be great.

Thanks

您可以使用StrictMode来检测在UI线程上执行的昂贵调用。

Why not try implementing your network call in an AsyncTask ? In the onPostExecute method implementation you can do whatever is necessary on the UI (ie hide your progressBar, etc.).

Or, if you are using the compatibility / support library , or targeting Honeycomb or later, use a Loader instead.
