One way to approach this is to add a field to the objects in your dataProvider that tracks whether or not the item has been selected. Then, in your item renderer, you inspect this field and decide whether or not to display the checkmark. Here’s a working example app and renderer: Application: <?xml version=”1.0″ encoding=”utf-8″?> … Read more
Suppose you have to create a program that prints a sum. You can create a file Sum.java with the Sum class inside it. Like this: public class Sum { public int x; public int y; public Sum(int x, int y) { this.x = x; this.y = y; } public int sumMyNumbers() { return x + … Read more
The std::valarray class + std::gslice can be used for administrating 2D, 3D … ND matrices. http://en.cppreference.com/w/cpp/numeric/valarray http://en.cppreference.com/w/cpp/numeric/valarray/gslice See some example in the link. If your intention is the image manipulation refer to the specific specialized libraries (jpeg, png ….). 2 solved No 2D Image container in c++ [closed]
<SCRIPT language=”javascript”> function addRow(tableID) { var table = document.getElementById(tableID); var rowCount = table.rows.length; if(rowCount < 10){ // limit the user from creating fields more than your limits var row = table.insertRow(rowCount); var colCount = table.rows[0].cells.length; for(var i=0; i <colCount; i++) { var newcell = row.insertCell(i); newcell.innerHTML = table.rows[0].cells[i].innerHTML; } }else{ alert(“Maximum Number of Books is … Read more
Check this out. You can iterate through the array and keep on adding the to the result array based on the item index. var object32 = [[“fgd”,”dsg”,”dsgds”],[“dgfs”,”ewrw”,”zsf”],[“mmm”,”ewrw”,”zsf”]]; let results = [] object32.map(obj => { obj.map((o, i) => { results[i] = results[i] ? results[i] + ‘ = ‘+ o : o; }) }) results.forEach(r => console.log(r)); … Read more
Using foreach on a string will produce a sequence of char, so declaring part as a string is not valid. Declare part as char or use var. do { //string test = questions[qCounter] = objReader.ReadLine(); string test = question.Split(‘?’)[qCounter]; qCounter++; foreach (char part in test) { Console.WriteLine(part); Console.ReadLine(); } } while (objReader.Peek() != -1 && … Read more
The correct code for Binary Search would be: while (l < r) { int m = (l + r) / 2; if (A[m] == X) { return m; } if (A[m] > X) { r = m – 1; } else if (A[m] < X) { l = m + 1; } } return -1; … Read more
Openears will support free speech recognition and text-to-speech functionalities in offline mode. They have FliteController Class Reference, which controls speech synthesis (TTS) in OpenEars. They have done an excellent job in speech recognition area. However, please note that it will detect only the words that you mentioned in vocabulary files.It iss good to work as … Read more
You can implement a simple linear SVM with numpy only like below. BTW, please google before you ask question next time. There are lots of resources and tutorial online. import numpy as np def my_svm(dataset, label): rate = 1 # rate for gradient descent epochs = 10000 # no of iterations weights = np.zeros(dataset.shape[1]) # … Read more
Ok here is the rewrite, the original code is better but this one might be easier to understand: #include <stdio.h> #include <string.h> int main() { char cur_char; char string[100]; int index = 0, count[255] = {0}; printf(“Enter a string\n”); gets(string); while (string[index] != ‘\0’) { char cur_char = string[index]; // cur_char is a char but … Read more
you are comparing two completely different things. The purposes of both frameworks are lays on different fields although they are intended for UI. Angular is the framework that allows you to separate model from view and controllers and structure your code in MVC patterns on the client side. So if you choose angular all your … Read more
The function does not make sense. For starters it is unclear why you are using a pointer to the vector instead of a reference to the vector. Nevertheles, this declaration vector<unsigned char> vec(5); does not reseeve a memory for the vector. It initializes the vector with 5 zero-characters which will be appended with other characters … Read more
It is well documented in the manual. An iterator that points to the first of the newly inserted elements. In you case new_foo_it after listOfFoos.insert of a single element, points to the last element of the list, it points newFoo. 1 solved In this C++ code, what element of the list does the iterator refer … Read more

The most important thing to apply this kind of design is properly implement adapter, which will represent every piece of data (one video in your situation). More or less in for situation it will look like: <RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android” android:layout_width=”match_parent” android:layout_height=”wrap_content”> //you main picture <ImageView android:layout_width=”fill_parent” android:layout_height=”fill_parent”> //layout to place other info like number of likes, … Read more
