Gson解析TypeToken指定泛型

今天碰到一组数据解析报错，特此记录…

[
    {
        "downloadPath": "9887b.apk",
        "equip": [
            "00000",
            "dcs",
            "0000"
        ],
        "upgrade": 3,
        "version": "3",
        "versionState": 1
    },
    {
        "downloadPath": "73e9c57.apk",
        "equip": [
            "64fe7ae",
            "dcs",
            "fe5dae397"
        ],
        "upgrade": 2,
        "version": "3",
        "versionState": 2
    }
]

需要用集合去接收，解析的时候总是报错，发现用Gson解析的时候没法确定返回数据的类型。所以用到
TypeToken去指定返回类型。

		List versionList
		String jsonStr = "返回的json数据";
		Gson gson = new Gson();
        List versionList;
        Type type = new TypeToken>() {
        }.getType();
        versionList = gson.fromJson(jsonStr , type);

通过指定解析返回的泛型，就OK了。
