问题 Hi I'm implementing a custom asynctaskloader to load data in the background. The problem is when the user goes back to the activity after he minimizes the app(or pick photo from gallary), all the asynctaskloaders associated with the activity and asynctaskloaders associated with the fragments in the activity start all over again. How can I prevent the loader to restart the loading process when the activity restarts? My baseAsynctaskLoader class: import android.content.Context; import android

问题 I have a problem with AsyncTaskLoader . When app is starting, it works fine. Then I call onRefreshStarted , and again all is good. But if change orientation, AsyncTaskLoader start processing loadInBackground , but onLoadFinished is never called. What is wrong? Here's simplified SherlockFragment: public class MyFragment extends SherlockFragment implements LoaderCallbacks<Object> { PullToRefreshLayout Rl; public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle

RejectedExecutionException 128 Active Threads AsyncTaskLoader

问题 I've searched around for solutions to RejectedExecutionException using AsyncTaskLoader but none have worked. Most of them are for AsyncTask like https://github.com/commonsguy/cwac-task/blob/master/src/com/commonsware/cwac/task/AsyncTaskEx.java but AsyncTaskLoader is kind of different. The first thing I tried was in onCreateLoader() doing this before returning a CursorLoader. if (loaderCount >= 100) { cursorLoader.setUpdateThrottle(1000000000); } All that really does is stop the loaders after

问题 I have a ViewPager with a FragmentStatePagerAdapter. In the onViewCreated method of the ViewPager fragments I call the initLoader method of the LoadManager to start an AsyncTaskLoader like this public void onViewCreated(final View view, Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); list = (ListView) view.findViewById(R.id.list); list.setEmptyView(view.findViewById(R.id.empty)); getLoaderManager().initLoader(0, null, this).forceLoad(); } The fragment of course

问题 Is there some way to interrupt AsyncTaskLoader 's loadInBackground() thread when I call cancelLoad() ? I believe that AsyncTask.cancel() does this but the task variables are private and cannot be accessed. 回答1: Use stopLoading() or abandon() or reset() for that Article: https://plus.google.com/117981280628062796190/posts/8b9RmQvxudb 回答2: It's relatively simple to add that functionality, this is the Gist of it: public abstract class InterruptibleAsyncTaskLoader<D> extends AsyncTaskLoader<D> {

I tried toying around with different values but it seemed like a waste of

AsyncTaskLoader onLoadFinished with a pending task and config change

混江龙づ霸主 提交于 2019-12-03 06:45:55
问题 I'm trying to use an AsyncTaskLoader to load data in the background to populate a detail view in response to a list item being chosen. I've gotten it mostly working but I'm still having one issue. If I choose a second item in the list and then rotate the device before the load for the first selected item has completed , then the onLoadFinished() call is reporting to the activity being stopped rather than the new activity. This works fine when choosing just a single item and then rotating.

Update progressbar from AsyncTaskLoader?

戏子无情 提交于 2019-12-03 04:22:30
问题 When using a AsyncTaskLoader how would you update a progressbar showing the status as it is being updated? Normally you wait for the callback to remove when done, but how to do running updates? Would you let the main thread (ui) poll the data as it is being set or something? Edit: I'm talking about AsyncTaskLoader , look at the loader part. Here is link to class: http://developer.android.com/reference/android/content/AsyncTaskLoader.html I want to use it because its the future :), I know how
