The same text on all items during keyboard input on Android.

Description of functionality of my project:
I have AddButton on screen. When I click on it there new item appear on screen. I click again - one more item.
I should be able to change text on each of those items by clicking on it: software keyboard opens and I enter text.

Problem:
If I click on first item - it's ok. But when I click on second one I notice that text on previously clicked item being changed too. As if they would share one text. But text on items should be independent.

There 2 classes in script file.
One controls AddButton and another class gonna be attached to newly created item on button click.

I would very appreciate if someone would take a look. Thanks.

This is script:

Code (CSharp):

1. public class AddItem : MonoBehaviour {
2.     ...
3.     void Start () {
4.         buttons = new ArrayList();
5.          coordY = 400;
6.         addButton = this.GetComponent<Button>();
7.         addButton.onClick.AddListener(AddButtonClicked);
8.     }
9.     void AddButtonClicked () {
10.         ...
11.         buttons.Add(newButton);
12.     }
13. ...
14. }
15.  
16. public class ItemController : MonoBehaviour {
17. ...
18.     void Start () {
19.         thisItem = this.GetComponent<Button>();
20.         thisItem.onClick.AddListener(OpenKeyboard);
21.     }
22.  
23.     void Update() {
24.         if (keyboard != null && keyboard.active)
25.             thisItem.GetComponentInChildren<Text>().text = keyboard.text;
26.     }
27.  
28.     void OpenKeyboard() {
29.         keyboard = TouchScreenKeyboard.Open("", TouchScreenKeyboardType.ASCIICapable, false, false, false, false);  
30.         thisItem.GetComponentInChildren<Text>().text = keyboard.text;
31.     }
32. }

 

Eww....Arraylist...ok, I'll save judgement

The issue is your Update. How does Update know which Text is suppose to change?

Right now, all your buttons run Update and check if keyboard != null && keyboard.active.

So as soon as those two values are true, the button will update it's text.

You'll need a way to designate if it's not the target button that you clicked on last, to not update it's text. However, it wouldn't surprise me if there is a better way to do this where update isn't required.

 

Thank you very much Brathnann ! What about Arraylist ?

 

Arraylist are a catch all type of collection where it doesn't care what you put in it and requires casting to get out of it. Generally you could stick a GameObject, a string, an int, a sprite, etc into it and it wouldn't care.

Honestly, it's much better to just use a Generic list.

Code (csharp):

1. List<GameObject> buttons = new List<GameObject>();

Would be better for your example.

 

Thanks.
