我想使用Gson反序列化JSON数组。我试图这样做,但我不能这样做。
JSON数组:
[
{"ID":1,"Title":"Lion","Description":"bla bla","ImageURL":"http:\/\/localhost\/lion.jpg"},
{"ID":1,"Title":"Tiger","Description":"bla bla","ImageURL":"http:\/\/localhost\/tiger.jpg"}
]
我从PHP脚本中获取JSON数组:
$array = array (
array ( 'ID' => 1 , 'Title' => 'Lion' , 'Description' => 'bla bla' , 'ImageURL' => 'http:\/\/localhost\/lion.jpg' ) ,
array ( 'ID' => 2 , 'Title' => 'Tiger' , 'Description' => 'bla bla' , 'ImageURL' => 'http:\/\/localhost\/tiger.jpg' ) ,
);
echo json_encode ($array);

要反序列化JSONArray,您需要使用TypeToken。您可以从GSON user guide了解更多相关信息。示例代码:
@Test
public void JSON() {
Gson gson = new Gson();
Type listType = new TypeToken<List<MyObject>>(){}.getType();
// In this test code i just shove the JSON here as string.
List<Asd> asd = gson.fromJson("[{'name':\"test1\"}, {'name':\"test2\"}]", listType);
}
如果您有JSONArray,那么您可以使用
...
JSONArray jsonArray = ...
gson.fromJson(jsonArray.toString(), listType);
...
