Set charsequence size after declaration

Question

Ok, so I have something like:

CharSequence[] lines;

and then I want to set its size in an Android Dialog click, like:

lines = new CharSequence[131];

but it will end up empty.

I need to populate a dialog with its values, but if I would do something like:

CharSequence[] lines = new CharSequence[131];

in the beginning and then populating it, then I will get an error when scrolling because of the null options in the dialog (no of options < 131).

I am kind of a beginner in Java. Any help would be appreciated.

if its empty, then you must to insert to it – Randyka Yudhistira Jan 25 '17 at 08:54 — Randyka Yudhistira, Jan 25 '17 at 08:54

can you post your code including data insert to that array? – Randyka Yudhistira Jan 25 '17 at 09:06 — Randyka Yudhistira, Jan 25 '17 at 09:06

Two options:

You check when a cell is empty lines[i] != null
You fill lines with data using Arrays.fill(lines, new CharSequence()) see the doc
