I'm trying to make an app whoes purpose is to show string arrays in a listview.
I have an XML file stored in the res/values folder whitch contains several string arrays, the arrays are named list1, list2, list3 etc.
Now, I want to show the arrays one by one by cliking a "Next" button in my UI.
I want the "Next" button to clear the current array and load the next one.
Can anyone help?

I have an array of objects stored in my main component(to avoid using redux). When I display the tasks, the list comes as a single entity, just like a paragraph. I want to separate each task and add two buttons in front of each task.
this is my code to display the array of objects
this is a image of list
from this list I want to create new array and add only checked items in new array, I don t know exactly data that will be in this list and I want dynamic solution for this problem. Sorry I could not show you the code I have no idea how the code might look.
So here I made a class with two properties named Item. I am appending the item in the array but when I run the app I can only see two items: the first one and the last one. I appended five items. I can checkmark all 5 cells but only two items are displaying and one cell is not having a separating line.
This is the simulator image; as you can see no third item is showing but I can still check it and 3rd cell has no separator.
I have an application in VB.Net where I'm trying to fill a label with some string data that I have in an array. I have a ComboBox which holds some states as the index collection/values. When I select a particular value in the combobox, I want to pull string data from the assigned array, and populate the label with it as a "clickable link a browser window. I'm lost on this, yet here is what I have in my code stub:
Private Sub cboSelectState_SelectedIndexChanged(sender As Object, e As EventArgs) Handles cboSelectState.SelectedIndexChanged
'Create a string array
Dim AlabamaCities() As String = {"http://www.rolltide.com/", "http://www.crimsontidehoops.com/", "http://centralalabamapride.org/"}
Dim strAlabama As String
'Populate label with the array data, on a particular value selection in combo box.
If cboSelectState.SelectedValue("Georgia") Then
strAlabama = CStr(AlabamaCities(3))
lblLinkOutput.Text = strAlabama
End If
End Sub
So when I pick Alabama in my combo box, I want the label to show:
http://www.rolltide.com
http://www.crimsontidehoops.com
http://centralalabamapride.org
The links will be clickable from the label and populate in the same tab whenever clicked. I haven't tried the clickable link part yet, and I will try once I get this down.
I know it's probably bad starting form out the gate. But I'm trying to get the form down to gain the knowledge and plan out a bigger project, and accomplish something better when I think of it. I appreciate your knowledge and assistance.
Firstly, it would make sense to use a Dictionary to store the data. The state names will be the keys and the values would be the arrays of URLs. You would then display the keys in the ComboBox and, when a selection is made, use the selected key to get the corresponding value from the Dictionary.
At that point, you won't be using a Label if you want clickable links. You should use a TableLayoutPanel as a container and then add one LinkLabel to the table for each URL in the array. You can then use a single handler for all the LinkClicked events.
I made a list of arrays using JSON and display it as links. Now, I have textboxes below the lists where the array list item would appear if it was clicked. How would I update the value of the array list item if I changed it on the textbox and clicked on save so that even if the page is refreshed, the new data should appear on the list instead of the old one.
By the way, the codes for the array, displaying the array, the textboxes and buttons are all in the same html page.
To start with, you can use JSON.stringify on the array object and put it in the text box. After manual editing, apply it to the array using JSON.parse.
