Data[] data = { 
     new Data(-79.400917f,43.661049f, "New New College Res", 
       "Residence building (new concrete high-rise)", "R.drawable.mr_kun"), 
     new Data(-79.394524f,43.655796f, "Baldwin Street",

你在這裏。

Data[] mergedArray = new Data[data.length + data2.length]; 
System.arraycopy(data, 0, mergedArray, 0, data.length); 
System.arraycopy(data2, 0, mergedArray, data.length, data2.length);

首先轉換您String array到List不是使用addAll梅託德添加List

例

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

我都試過，但錯誤..我喜歡的類型數組數據不串..請給我幫助.. – 2013-04-26 08:06:08

這就是爲什麼他寫了「FIRST轉換字符串數組到列表:-) – bofredo 2013-04-26 08:08:46

給我任何其他的解決方案..？ – 2013-04-26 08:09:56

您可以輕鬆使用Apache Commons Lang庫。
那麼你的代碼如下：

ArrayUtils.addAll(data, data2);

下面是該方法documetation：
