Data[] data = {
new Data(-79.400917f,43.661049f,"New New College Res",

new Data(-79.394524f,43.655796f,"Baldwin Street",
"Here be many good restaurants!","R.drawable.mr_kun"),
new Data(-79.402206f,43.657688f,"College St",
"Lots of discount computer stores if you forgot a cable or need to buy hardware.","R.drawable.mr_kun"),
new Data(-79.390381f,43.659878f,"Queens Park Subway",
"Quickest way to the north-south (Yonge-University-Spadina) subway/metro line","R.drawable.mr_kun"),

};

Data[] data2 = {
new Data(-79.403732f,43.666801f,"Spadina Subway",
"Quickest way to the east-west (Bloor-Danforth) subway/metro line","R.drawable.mr_kun"),
new Data(-79.399696f,43.667873f,"St George Subway back door",
"Token-only admittance, else use Spadina or Bedford entrances!","R.drawable.mr_kun"),
new Data(-79.384163f,43.655083f,"Eaton Centre (megamall)",
"One of the largest indoor shopping centres in eastern Canada. Runs from Dundas to Queen.","R.drawable.mr_kun"),
};

首先把你的String array转换成List而不是用addAllmetod来添加List。

ArrayList<String> first;
ArrayList<String> second;
second.addAll(first);
