GSON拋出“預(yù)期的BEGIN_Object但是BEGIN_數(shù)組”？我正試圖解析像這樣的JSON字符串[ { "updated_at":"2012-03-02 21:06:01", "fetched_at":"2012-03-02 21:28:37.728840", "description":null, "language":null, "title":"JOHN", "url":"http://rus.JOHN.JOHN/rss.php", "icon_url":null, "logo_url":null, "id":"4f4791da203d0c2d76000035", "modified":"2012-03-02 23:28:58.840076" }, { "updated_at":"2012-03-02 14:07:44", "fetched_at":"2012-03-02 21:28:37.033108", "description":null, "language":null, "title":"PETER", "url":"http://PETER.PETER.lv/rss.php", "icon_url":null, "logo_url":null, "id":"4f476f61203d0c2d89000253", "modified":"2012-03-02 23:28:57.928001" }]變成一個(gè)對(duì)象列表。List<ChannelSearchEnum> lcs = (List<ChannelSearchEnum>) new Gson().fromJson( jstring , ChannelSearchEnum.class);我該怎么解決呢？

問(wèn)題是，您要求的是一個(gè)類(lèi)型的對(duì)象。ChannelSearchEnum但你真正擁有的是一個(gè)類(lèi)型的對(duì)象List<ChannelSearchEnum>.

您可以通過(guò)以下方式實(shí)現(xiàn)這一點(diǎn)：

Type collectionType = new TypeToken<List<ChannelSearchEnum>>(){}.getType();List<ChannelSearchEnum> lcs = (List<ChannelSearchEnum>) new Gson()
               .fromJson( jstring , collectionType);
