我在我的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？如何做到这一点？

我正试图获得这样的JSON字符串，但收到错误

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();
}

您可以简单地使用以下代码。

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;
}
