Android的轉換列表<String[]>爲String []

Question

的Android如何轉換List<String[]>到String[] .....

Answer 1

static String[] convert(List<String[]> from) { 
     ArrayList<String> list = new ArrayList<String>(); 
     for (String[] strings : from) { 
      Collections.addAll(list, strings); 
     } 
     return list.toArray(new String[list.size()]); 
    } 

使用例：

public static void main(String[] args) { 
     List<String[]> list = new ArrayList<String[]>(); 
     list.add(new String[] { "one", "two" }); 
     list.add(new String[] { "three", "four", "five" }); 
     list.add(new String[] { "six", "seven" }); 
     String[] converted = convert(list); 
     System.out.print(converted.toString()); 
    }
