I have a progress bar in viewHolder class inside adapter class. I need to update that bar from another activity UpdateActivity when the method onSavedState in that activity is implemented. I have tried using the interface but it does not update the progress bar, the bar remains as before with no error as well. public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> { public static class MyViewHolder extends RecyclerView.ViewHolder implements MyCallBack{ ProgressBar progressBar; public MyViewHolder(@NonNull View itemView) { super(itemView); progressBar = itemView.findViewById(R.id.progress_bar); } @Override public void updateMyText(int integer) { progressBar.setProgress(integer); } } } interface MyCallBack { public void updateMyText(int integer); } public class UpdateActivity extends AppCompatActivity { MyCallBack myCallBack; @Override public void onSavedState() { myCallBack = new MyCallBack() { @Override public void updateMyText(int integer) { progressBar.setProgress(100); Toast.makeText(PlayerActivity.this, "call back", Toast.LENGTH_SHORT).show(); } }; } } }

I'm not familiar with targeting arrays within arrays such as in the JSON data I'm working with. How do you make a foreach loop using PHP for the [1] [2] [3][and so on....] keys (and ultimately the value for [venue]) that are nested inside of [data] in an example like below? This is the format returned to me after I've used json_decode. <?php $data = file_get_contents ("https://api.example.com/data.json"); $data = json_decode ($data, true); print_r($data); ?>
Array ( [count] => 1 [data] => Array ( [0] => Array ( [location] => Array ( [venue] => Someplace Building ) ) [1] => Array ( [location] => Array ( [venue] => Some Other Building ) ) [2] => Array ( [location] => Array ( [venue] => Some Other Building ) ) ) )

I want to know if a microsecond timestamp is enough to prevent duplicate datetime? If that's not enough I want to know what guarantees a unique timestamp? Is there a case where a Database can insert or update less than 1 microsecond? Why I need a unique timestamp because I am doing data synchronization where rely on DateTime to check if new data available Thank you

When I am using this code to parse a rss xml source(the app using embedded tomcat and running in CentOS 7.x, using Java 11 AdoptJDK): package com.dolphin.soa.post; import com.rometools.rome.feed.synd.SyndFeed; import com.rometools.rome.io.SyndFeedInput; import com.rometools.rome.io.XmlReader; import lombok.extern.slf4j.Slf4j; import java.net.URL; /** * @author dolphin */ @Slf4j public class MiniExample { public static void main(String args) { try { URL url = new URL("https://zpblogs.cn/feed/"); SyndFeed feed = new SyndFeedInput().build(new XmlReader(url)); System.out.print(feed.getCopyright()); }catch (Exception e){ log.error("error",e); } } }
this is the package I am using: api "com.rometools:rome:1.15.0"
but show this error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
why woud this happen? I have read this question, all tell that should using keytool to import the cert, but my rrs url has more than 1000000+, import the cert one by one, seems it hard to implement? what should I do to fix this problem?

[![enter image description here][1]][1]Calculating over time hours for employees against their individual contract hours, the percentage an employee has worked overtimes as well as how many worked more than 10% overtime. Sample data is here: http://sqlfiddle.com/#!9/a2ba19/2/0 Sample data has: ID- Employee ID PROJECT - Project code Employee belongs to SEGMENT - are the projects an employee is working on SEG_DESC- description of the projects CONTRACT HRS- is the individual contract hrs the employee is hired to do HOURS - are the hours an employee has worked in a segment TEAM- Employee belongs to END_OF_WEEK - data is collected weekly I need the the percentage an employee has worked overtime how many employees have worked more than 10% overtime Once these calculations are done, I need to be able to visualise the data in Power BI. I have actually achieved all I needed to do in Power BI - but the dashboard is extremely slow and therefore not viable. Therefore, the overtime calculations need all to already happen in sql. How can I do this? While I would be thankful for the calculations, the main issue I perceive to have is that as soon as I sum all the hours an employee has worked in a one week, I am actually ending up aggregating the data. But I need not aggregated data to be able to visualise other elements, such as which segments cost most hours for employees to work on for example.

I'm new to Kotlin and Spring Boot. I'm trying to call SearchService class with initialized constructors through ServiceClass, everything is fine until it's time to access Autowired env variable in SearchService - it throws Null Pointer Exception. I'm assuming I will have to Autowire SearchService in ServiceClass but then how will I initialize the constructor and name/isAlive variables in the performSearch method. @Service class ServiceClass { @Autowired lateinit var env: Environment fun performSearch(req: String): String { var searchService = SearchService("John", false) result = searchService.searchAsync() ... return result } } @Repository class SearchService(name: String = "", isAlive: Boolean = true) { private var name: String = name private var isAlive: Boolean = isAlive @Autowired lateinit var env: Environment fun searchAsync(): String { var endpoint = env.getProperty("endpoint").toString() + name //Error here // makes call to get endpoint with Name and isAlive as params ... return result } }

I am a newbie to Go. Was starting to write my first code in which I have to download a bunch of CSV's from AWS. I don't understand why it is giving me the below error with O_APPEND mode. If I remove os.O_APPEND, I only get the last file data which is not the objective. The objective is to download all CSV files into one file locally. I'd like to understand what I'm doing incorrectly. package main import ( "fmt" "os" "path/filepath" "github.com/aws/aws-sdk-go/aws" "github.com/aws/aws-sdk-go/aws/credentials" "github.com/aws/aws-sdk-go/aws/session" "github.com/aws/aws-sdk-go/service/s3" "github.com/aws/aws-sdk-go/service/s3/s3manager" ) const ( AccessKeyId = "xxxxxxxxx" SecretAccessKey = "xxxxxxxxxxxxxxxxxxxx" Region = "eu-central-1" Bucket = "dexter-reports" bucketKey = "Jenkins/pluginVersions/" ) func main() { // Load the Shared AWS Configuration os.Setenv("AWS_ACCESS_KEY_ID", AccessKeyId) os.Setenv("AWS_SECRET_ACCESS_KEY", SecretAccessKey) filename := "JenkinsPluginDetais.txt" cred := credentials.NewStaticCredentials(AccessKeyId, SecretAccessKey, "") config := aws.Config{Credentials: cred, Region: aws.String(Region), Endpoint: aws.String("s3.amazonaws.com")} file, err := os.OpenFile(filename, os.O_APPEND|os.O_WRONLY|os.O_CREATE, 0666) if err != nil { panic(err) } defer file.Close() sess, err := session.NewSession(&config) if err != nil { fmt.Println(err) } //list Buckets ObjectList := listBucketObjects(sess) //loop over the obectlist.

I want to read textarea value using JavaScript. Here is my code: I use JavaScript in async way. Hopefully we can use textarea inside the form. This is not a fault. function validate() { let title = document.getElementById("title").value; document.write(title); let textarea = document.querySelector("#textarea1").value; document.write(textarea); let image = document.getElementById("myimage").value; document.write(image) }

I am using getx on my project . I have RxList and buy Obx I shows my data on widget: RxList<VocabularyModel> vocabs = RxList();
and widget: return Scaffold( body: SafeArea( child: Obx( () => ListView.builder( // ignore: invalid_use_of_protected_member itemCount: controller.vocabs.value.length, itemBuilder: (context, index) { return Padding( padding: EdgeInsets.symmetric(vertical: 8.h, horizontal: 8),
In controller I have method to remove on object in vocabs: void changeToRememberState(int index) { final upateItem = vocabs.value[index].copyWith(remember: true); vocabs.value.removeAt(index); // repository.changeToRememberState(index, upateItem); }
But when I remove object from vocabs, Obx builder not triggered? Why? I remove one element from RxList, Why RxList not fire?

Hi I had this code written for me in C++, it splits a given sentence into 4 letter segments and converts those letters into numbers. #include<iostream> #include<string> #include <stdlib.h> using namespace std; void splitString(string input) { char* result = new char[1000]; result[0] = '['; int resultindex = 1; int spaces = 0; for (int i = 0; input != '\0'; i++) { if (input[i] == ' ') spaces++; } spaces++; int k = 0; bool flag = true; for (int i = 0; i < spaces; i++) { char* temp = new char[100]; int j = 0; while (input[k] != ' ') { if (input[k] == '\0') { flag = false; break; } temp[j] = input[k]; k++; j++; } k++; temp[j] = '\0'; int length = 0; for (int i = 0; temp[i] != '\0'; i++) { length++; } bool firstTime = true; if (length <= 4) { for (int i = 0; temp[i] != '\0'; i++) { if (firstTime) { if (int(temp[i]) >= 65 && int(temp[i]) <= 90) { result[resultindex] = temp[i]; resultindex++; firstTime = false; } else { result[resultindex] = temp[i] - 32; resultindex++; firstTime = false; } } else { result[resultindex] = temp[i]; resultindex++; } } if (i != spaces - 1) { result[resultindex] = ','; resultindex++; } } else { int j = 0; while (length > 4) { int quotient = length / 2; for (int i = 0; i < quotient; i++) { if (firstTime) { if (int(temp[j]) >= 65 && int(temp[j]) <= 90) { result[resultindex] = temp[j]; resultindex++; j++; firstTime = false; } else { result[resultindex] = temp[j] - 32; resultindex++; firstTime = false; j++; } } else { result[resultindex] = temp[j]; resultindex++; j++; } } length = length - quotient; result[resultindex] = ','; firstTime = true; resultindex++; } for (int i = 0; i < length; i++) { if (firstTime) { if (int(temp[j]) >= 65 && int(temp[j]) <= 90) { result[resultindex] = temp[j]; resultindex++; j++; firstTime = false; } else { result[resultindex] = temp[j] - 32; resultindex++; firstTime = false; j++; } } else { result[resultindex] = temp[j]; resultindex++; j++; } } if (i != spaces - 1) { result[resultindex] = ','; resultindex++; } } if (!flag) break; } result[resultindex] = ']'; resultindex++; std::cout << endl; std::cout << "String after spliting " << endl<<endl; for (int i = 0; i < resultindex; i++) std::cout << result[i]; std::cout << endl<<endl; std::cout << "Letter Converted in number" << endl << endl; std::cout << "["; for (int i = 0; i < resultindex; i++) { if (result == ',') { std::cout << "]"; std::cout<<","; std::cout << "["; continue; } float ascii = float(result); if (ascii >= 97 && ascii <= 122) { ascii -= 96; ascii *= 51.2; std::cout << ascii; if (result[i + 1] != ',' && result[i + 1] != ']') { std::cout << ","; } } else if (ascii >= 65 && ascii <= 90) { ascii -= 64; ascii *= 51.2; std::cout << ascii; if (result[i + 1] != ',' && result[i + 1] != ']') std::cout << ","; } else std::cout << result[i]; } std::cout << "]"; std::cout << endl<<endl; } int main() { std::cout << "Enter sentence:"; string input; getline(cin, input); splitString(input); system("pause"); }
The only thing is that I now need to iterate through these arrays and have no clue on where to even start. Where is the actual output for the program? How can I iterate through each number in a useable way? I want behavior exactly like this(written in python): for x in output: for number in x: MoveAMotor(number)
But cannot fathom how something like this would be done in C++. I'm not very familiar with the language and it seems much harder than in python. Can someone get me an idea of where the output of the program is, and how I could get started iterating through the nested arrays of the output. I greatly appreciate it

this question builds off of this solution provided at enter link description here as follows. library(ggplot2) library(gtable) library(grid) diamonds$cut = factor(diamonds$cut, levels=c("Fair","Good"," ","Very Good", "Premium","Ideal")) p = ggplot(diamonds, aes(color, fill = cut)) + geom_bar() + scale_fill_manual(values = c(hcl(seq(15, 325, length.out = 5), 100, 65)[1:2], "white", hcl(seq(15, 325, length.out = 5), 100, 65)[3:5]), drop = FALSE) + guides(fill = guide_legend(ncol = 2, title.position = "top")) + theme(legend.position = "bottom", legend.key = element_rect(fill = "white")) # Get the ggplot grob g = ggplotGrob(p) # Get the legend leg = g$grobs[[which(g$layout$name == "guide-box")]]$grobs[] # Set up the two sub-titles as text grobs st = lapply(c("First group", "Second group"), function(x) { textGrob(x, x = 0, just = "left", gp = gpar(cex = 0.8)) } ) # Add a row to the legend gtable to take the legend sub-titles leg = gtable_add_rows(leg, unit(1, "grobheight", st[]) + unit(0.2, "cm"), pos = 3) # Add the sub-titles to the new row leg = gtable_add_grob(leg, st, t = 4, l = c(2, 6), r = c(4, 8), clip = "off") # Add a little more space between the two columns leg$widths[] = unit(.6, "cm") # Move the legend to the right leg$vp = viewport(x = unit(.95, "npc"), width = sum(leg$widths), just = "right") # Put the legend back into the plot g$grobs[[which(g$layout$name == "guide-box")]] = leg # Draw the plot grid.newpage() grid.draw(g)
This provides the figure (from there).
However, I want to do two things. First group: I want to relabel "Fair" and "Good" to "Very Good" and "Premium" respectively. So they are Very Good and Premium of each group (first and second). The second thing I would like to do is to put them in one line (in two columns of First group and second group side by side, everything in one line, to save vertical space. How do I do this? Please let me know if my questions are not clear. I feel like I am quite close here, but this solution does not quite answer my question. Many thanks!
