newsreader | newsreader using the HackerNews Api | Frontend Utils library

Hi guy im would like to do a easy newsreader app. in shared preferences the user could choose which news sections he can see. I com until the Point to add MultiSelectListPreference and retrieve th values. But unfortunatly it retrieves all values and not only the checked.

Here is my code:

I'm trying to implement a Newsreader app following Udemy "Complete Android N Developer Course".List view is used.

As per the instruction I have correctly followed but when executing the below main activity though it is required to update the list items with titles, this shows nothing in the list view. No errors even in the Android Monitor.

Any suggestion to find the issue, please.

Thank you!

I have a fragment that is getting data passed by reference from a Utils class. However, when I ran my code I got a null pointer exception

I have a training and testing dataset from the 20NewsGroups dataset available in sklearn. I have imported the data and created a bag of words that I can use to run it through a naive bayes classifier. Current code is below:

I'm building a practice newsreader app. And want to show articles in a tableview.

The articles can be favorited. And in the tabbar i want to have a extra tab for only my favorited articles. I don't want to make another table view because all i have to do is get a differt api call.

Is it possible to check which relationship root -> tableview is used to enter the view?

I have an issue about the plot of a 2D map with color bar. In my application, I have data with a size of map equal to 258x98.

If I plot these data with surf and shading interp, everything is good.

But if I plot them with shading faceted, different rows at the upper horizontal part of map seem to be missing.

The upper border is not initially red like in the shading interp; version.

I found a post which talks about this problem; it may come from shading faceted default behavior.

Could anyone confirm that the rows are missing when plotting? How can I fix it so that all boundaries data are plotted with shading faceted?

I tried to reproduce the issue with a simple example. Here's a simple Matlab script :

I have a menu with two options. One of the options refreshes the content of the app with web content. I want to dim the ListView that's on the screen and then display a progress bar until the content refreshes. I have methods startLoadingAnimation() and endLoadingAnimation() that accomplish this. But when I call refreshArticles() in between them, they stop working. I have print statements in them that show they execute when they should, but when

I've an array with the following structure:

I have a threshold requirement and would like to round values of a vector to 0 or 1. I don't need to save the old values of the vector

I saw, in the link below, that I could use the following to change the all values of 0 in the s vector to -1 with s( s==0 )=-1; or in general vector(if condition) = desiredValue.

This is better than using a for loop and having an enclosed if condition. What if I would like to include another condition: to change all values greater than 0.8 to 1? Would I have to add another line of code:s( s>=0.8 )=1; or is there a way of checking the two conditions by traversing the vector just once? I only know of using a for loop with an enclosed if-else condition but would like a shorter version if one exists.
