Gson gson=new Gson();
List<物件>  vol = gson.fromJson(jsonStr, new TypeToken<List<物件>>(){}.getType());

如果json陣列中 含有比如list 的集合元素  也可以用這種方法

	public class A{
		private int id;
		private String title;
		private String photo;
		private List<B> list;｝

public class B{   這個類中的欄位屬性 是類A中List中存在的屬性欄位
	private int id;
	private String title; 
	private int size; 
	private String photo;
	private String headerImg
 

[
    {
        "id": "5", 
        "title": "強烈推薦", 
        "photo": "", 
        "list": [
            {
                "id": "6", 
                "title": "aaa", 
                "size": "1", 
                "photo": "/files/2014-03-19/489284939.jpg", 
                "headerImg": "/files/2014-03-19/972303602.jpg"
 

            }, 
            {
                "id": "8", 
                "title": "bbb", 
                "size": "0", 
                "photo": "/files/2014-03-19/153049045.jpg", }
