我的 Android 工作室本地有这个 JSON 文件，我想使用 Gson 库读取它并实现 Room？如何实现？

我正在尝试获取这样的 JSON 字符串，但出现错误

   String json;
    try {
        InputStream is = getResources().openRawResource(R.raw.names);
        if (is != null) {
            InputStreamReader inputStreamReader = new InputStreamReader(is);
            BufferedReader reader = new BufferedReader(inputStreamReader);

            String line = "";
            StringBuilder sb = new StringBuilder();

            while ((line = reader.readLine()) != null) {
                sb.append(line);
            }
            is.close();
            json = sb.toString();

            Log.d(TAG, "readData: data recived" + json);

        }
    } catch (IOException e) {

        e.printStackTrace();
    }

您可以简单地使用下面的代码。

 String jsonOutput; // Your json string
 Type listType = new TypeToken<List<RoomModel>>() {}.getType();
 ArrayList< RoomModel > rooms = new Gson().fromJson(jsonOutput, listType);


public class RoomModel
{
    public int ID,
    public String Gender;
    public String Meaning;
    public String Name;
    public String Origin;
}
