如何组合两个阵列

Question

我在我的应用程序中有两个数组，在这种情况下，我想在我的应用程序中组合两个数组，但我尝试并失败..这是我的代码..请组合阵列数据和数据2：

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", 
       "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"), 
}; 

Answer 1

你在这里。

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); 

Answer 2

首先转换您String array到List不是使用addAll梅托德添加List

例

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

Answer 3

您可以轻松使用Apache Commons Lang库。
那么你的代码如下：

ArrayUtils.addAll(data, data2); 

下面是该方法documetation：
