当前数据库中有可用数据,我无法提取它们。例如;我想获取具有会员ID号的数据,但是我无法添加
package com.example.app.test_network;
import java.util.List;
import com.example.app.test_network.af_model.Contact;
import io.reactivex.Single;
import retrofit2.http.GET;
import retrofit2.http.Query;
public interface ApiService {
private com.example.app.membership.helper.SQLiteHandler db;
private com.example.app.membership.helper.SessionManager session;
db = new com.example.app.membership.helper.SQLiteHandler(getApplicationContext());
session = new com.example.app.membership.helper.SessionManager(getApplicationContext());
// Fetching user details from SQLite
HashMap<String, String> user = db.getUserDetails();
@GET("members?memberID="+user.get("memberIDno"))
Single<List<Contact>> getContacts(@Query("source") String source, @Query("search") String query);
}
这是怎么回事?
