Question

I need to create one textview array, i’d like to show or hide one image depending position.
I’ll try to explain it:
I’ve one layout similar this:

1 2 3 4 5

And depending random value show or hide an image in textview 1 or 2, etc…

I can use:

if (a == 4)

 {

t4.setBackgroundResource(R.drawable.ficha);

t1.setBackgroundDrawable(null);

t2.setBackgroundDrawable(null);

t3.setBackgroundDrawable(null);

t5.setBackgroundDrawable(null);

}

else if (a==5)

...

..

But i’d like to know, if it’s possible to pass the number t(1) using parameters or something similar.

Thanks in advance and sorry about my english.

Answer 1

Or you can use List<TextView> tvList = new ArrayList<TextView>();
add as many textviews as you like

and this will retrieve a textview and set background from a list depending on your a value :

((TextView)tvList.get(a)).setBackgroundResource(R.drawable.ficha+a.....); 

1st 2nd and so on. you can use Arrays too of course for this purpose.
