I have two datasets which are currently in the same folder as my java files AND on my PC. Currently, I am accessing them through my C-drive. Since this is an app, where should I save my .ARFF files and what path should I use instead? I have tried in the raw folder, but nothing seems to work. Here's what I have so far... Create a raw directory in your project, raw is included in the res folder of android project. You can add an assets files in raw folder like music files, database files or text files or some other files which you need to access directly 1) Right click on res folder, select New>

问题 Is it possible to save and restore the state (which items are collapsed and which not) of an ExpandableListView in Android? If it is possible, how can I do that? Can I access the ExpandableListView in onPause() / onResume() and how? 回答1: I iterate through the groups and save the state of them all: int numberOfGroups = MyExpandableListViewAdapter.getGroupCount(); boolean[] groupExpandedArray = new boolean[numberOfGroups]; for (int i=0;i<numberOfGroups;i++) groupExpandedArray[i] =

Loading and Saving vectors to a file

烂漫一生 提交于 2019-12-03 21:32:47
I am using C++ Builder and I have a vector array of Appointment objects. I want to save it to and load it from a file. Currently, I am using ifstream and ofstream with binary files. I have a header that contains the size of the vector that will be saved alongside the data, so as to know its size when loading. Is serilization a better way to do this? If so, do I need to use the boost library, or another way? Here is my current code: class appointment { public: appointment(); appointment(TDateTime aDate, TDateTime aReminderDateTime, string aType, string aLocation, string aComments, bool

Is there a simple way to make and save an animation with Pygame?

I made a very simple fractal generator that prints out each step; I want to put it in a presentation I made. The tool with which I'm making the presentation obviously doesn't support pygame, is there any way to save it as a video? Preferably as an animated .gif or the like. Not directly. But you can save a screencast of your program with one of the many available utilities that do this. I don't know about Windows or OSX, but if you are on Ubuntu or other gnome-based desktop you can either use the gnome-shell built-in functionality (standard keybinding is Control+Shift+Alt+R ) or istanbul (more

Django: accessing ManyToManyField objects after the save

浪子不回头ぞ 提交于 2019-12-03 21:11:22
This is baffling me... When I save my model, the book objects are unchanged. But if I open the invoice and save it again, the changes are made. What am I doing wrong? class Invoice(models.Model): ... books = models.ManyToManyField(Book,blank=True,null=True) ... def save(self, *args, **kwargs): super(Invoice, self).save(*args, **kwargs) for book in self.books.all(): book.quantity -= 1 if book.quantity == 0: book.sold = True; book.save() Edit: I've tried using the post_save signal, but it works the same way. No changes on the first save, changes saved the second time. Update: Seems to be solved

Save recorded audio to file - OpenSL ES - Android

I'm trying to record from the microphone, add some effects, and the save this to a file I've started with the example native-audio included in the Android NDK. I'va managed to add some reverb and play it back but I haven't found any examples or help on how to accomplish this. Any and all help is welcome. OpenSL is not a framework for file formats and access. If you want a raw PCM file, simply open it for writing and put all buffers from OpenSL callback into the file. But if you want encoded audio, you need your own codec and format handler. You can use ffmpeg libraries, or built-in stagefright

Generate some xml in javascript, prompt user to save it

问题 I'd like to make an XML document in JavaScript then have a save dialog appear. It's OK if they have to click before the save can occur. It's *not* OK if I *have* to use IE to achieve this (I don't even need to support it at all). However, Windows is a required platform (so Firefox or Chrome are the preferred browsers if I can only do this in one browser). It's *not* OK if I need a web server. But conversely, I don't want to require the JavaScript to be run on a local file only, i.e. elevated
