Json 数据解析

Type 1:

通过 JsonArray 和 JsonObject 解析

String str= String.format("[{"id":"5","version":"5.5","name":"Name1"}," +
        "{"id":"6","version":"6.6","name":"Name2"}]");
try {
    JSONArray jsonArray=new JSONArray(str);
    for (int i=0;i<jsonArray.length();i++){
        JSONObject obj=jsonArray.getJSONObject(i);
        Log.e(TAG, "onCreate: "+obj.getString("id"));
        Log.e(TAG, "onCreate: "+obj.getString("version"));
        Log.e(TAG, "onCreate: "+obj.getString("name"));
    }
} catch (JSONException e) {
    e.printStackTrace();
}

Type2：

compile 'com.google.code.gson:gson:2.7'

        Gson gson = new Gson();
        listNew = gson.fromJson(result, new TypeToken<List<RankData>>() {}.getType());
