how add together new elements array? 12 answers

is there way add together new items array?

rowmsg rowmsg_data[] = new rowmsg[] { new rowmsg(r.drawable.ic_launcher, "message 1"), new rowmsg(r.drawable.ic_launcher, "message 2"), new rowmsg(r.drawable.ic_launcher, "message 3"), new rowmsg(r.drawable.ic_launcher, "message 4") }; // here want add together next 1 element, example: rowmsg(r.drawable.ic_launcher, "message 5")

no. can't add together elements arrays - 1 time you've created array, size can't change.

you'd improve off list:

list<rowmsg> messages = new arraylist<rowmsg>(); messages.add(new rowmsg(r.drawable.ic_launcher, "message 1")); // etc

as aside, it's more conventional maintain type info in 1 place, , java variables conventionally camel-cased - if did stick array, improve declare as:

rowmsg[] rowmsgdata = new rowmsg[] { ... };

(i'd suggest avoiding abbreviations, there go.)
