com.google.gson.internal.LinkedHashTreeMap无法转换为我的对象

试试这个：

HashMap<String, FeatureDetails> featuresFromJson = new Gson().fromJson(JSONFeatureSet, new TypeToken<Map<String, FeatureDetails>>() {}.getType());

当您遍历哈希图时，请执行以下操作：

for (Map.Entry<String, FeatureDetails> entry : featuresFromJson.entrySet()) {         FeatureDetails featureDetails = entry.getValue();}
