[ad_1] you are providing null list on adapter adapterData = new AdapterData(getActivity(), listdata); initlize “listdata” with new before sending to adapter, like listdata = new ArrayList<Data>; [ad_2] solved Android login and get json array [duplicate]
[ad_1] The trivial answer is to split the string: String[] fragments = theString.split(” “, 6); Given that the fragments have specific meanings (and presumably you want some of them as non-string types), it might be more readable to use a Scanner: Scanner sc = new Scanner(theString); int x = sc.nextInt(); int y = sc.nextInt(); int … Read more
[ad_1] In Python, indentation is crucial. After each :, you must indent at least at the next line so the interpreter understands the line belongs to the block. if month * day == year: print (‘The date is magic!’) else: print (‘The date is not magic.’) I suggest you to gather more information on how … Read more

It might be better to collect all the ‘dynamic’ definitions into a separate file (eg dynamic-styles.php) and import them … Read more
[ad_1] You can try like following using GROUP BY and UNION ALL. select count(*) CT,Mark from TableName group by Mark union all select Count(*), ‘A+B’ as mark from TableName where mark in(‘A’,’B’) UNION ALL select Count(*), ‘A+C’ as mark from TableName where mark in(‘A’,’C’) union all select Count(*), ‘B+C’ as mark from TableName where mark … Read more
[ad_1] What you’re looking for is a linear regression model. In R, it’s invoked with lm(). You can read more here. You’d want to fit a model predicting the grade, and then run the model on the data with the Age incremented by one, since presumably, that is the only attribute that will be changing … Read more
[ad_1] String.valueOf().length() returns 11 because that is the number of digits/characters in the output (i.e. [@936016386 – an address – has 11 characters) [ad_2] solved How do I properly test the char[ ] fields in my custom object for nulls, blanks, or empty? and Why do char[ ] indicate a length of 11?
[ad_1] Ok, let’s assume we have a dataframe data and list negative_words like this: data = pd.DataFrame({ ‘Tweets’ : [‘This is bad’, ‘This is terrible’, ‘This is good’, ‘This is great’], }) negative_words = [‘bad’, ‘terrible’] We can then do something like: 1) We can use a lambda function with any: # create lambda with … Read more
[ad_1] Right now you generate any word type just once. Just generate the randoms before any phase function makeAPoem() { var nouns = [“cat”, “crow”, “snow”, “home”, “boy”, “raven”, “tree”, “moon”, “night”, “day”, “winter”, “heart”, “angel”, “madam”, “darkness”, “chamber”, “lady”, “bird”, “person”, “eye”, “darkness”, “air”]; var verbs = [“ran”, “felt”, “fell”, “focused”, “looked”, “stared”, “sat”, … Read more
[ad_1] The problem wasn’t the c++ code itself, but the framework it used, in this case ROOT. If you define a pointer in a ROOT class, you have to tell the program what to do with that pointer in the case of the class being written to file. Even though the class might never be … Read more

[ad_1] Selenium treats frames as separated pages (because it has to load it separatelly) and it doesn’t search in frames. And page_source doesn’t return HTML from frame. You have to find <frame> and switch to correct frame switch_to.frame(..) to work with it. frames = driver.find_elements_by_tag_name(‘frame’) driver.switch_to.frame(frames[0]) import urllib from bs4 import BeautifulSoup from selenium import … Read more
[ad_1] I found the solution. You have to add a closure and then use it when calling the function. func getData(symbol: String, completion: @escaping (Stock) -> Void) { let apiURL = “https://cloud.iexapis.com/stable/stock/\(symbol)/quote?token=\(secretToken)” let url = URL(string: apiURL)! URLSession.shared.dataTask(with: url) { (data, response, err) in guard let data = data else { return } do { … Read more
