java向安卓项目添加score元素
我说我会展示下面三节课，这样你就能确切地知道我在做什么。我发布的三个类用于我正在开发的一个游戏，它们与应用程序的登录和注册部分有关。我想添加一个分数元素，当用户单击按钮并且满足某些条件时，该元素将增加。我只是想知道是否有人能帮我添加score元素（当用户单击按钮时，它将发布，您可以检索它）
服务器请求。爪哇

本地数据库。爪哇
public class LocalDatabase {
public static final String SP_NAME = "UserDetails";
//Shared Preferences allows us to store data on the phone
SharedPreferences localDatabase;
//A constructor for this class
public LocalDatabase(Context context)
{
localDatabase = context.getSharedPreferences(SP_NAME , 0);
}
//Storing the data
public void storeData(Contact contact)
{
//Allows us to edit the local database
SharedPreferences.Editor spEditor = localDatabase.edit();
spEditor.putString("Name" , contact.name);
spEditor.putString("Email" , contact.email);
spEditor.putString("Username" , contact.username);
spEditor.putString("Password" , contact.password);
//Saves the work
spEditor.commit();
}
//This is for getting the data for which user is current logged in
public Contact getLoggedInUser()
{
String name = localDatabase.getString("Name" , "");
String email = localDatabase.getString("Email" , "");
String username = localDatabase.getString("Username" , "");
String password = localDatabase.getString("Password", "");
//Parse your 4 variables
Contact storedContact = new Contact(name , email , username , password);
return storedContact;
}
//Tell us if the user is currently logged in or not.. THat's why we use a boolean
public void setUserLoggedIn(boolean loggedIn)
{
SharedPreferences.Editor spEditor = localDatabase.edit();
spEditor.putBoolean("loggedIn" , loggedIn);
//Save all the work
spEditor.commit();
}
//
public boolean getUserLoggedIn()
{
if(localDatabase.getBoolean("loggedIn" , false))
return true;
else
return false;
}
//When the user loggs out, it will clear all the temporary data off the phone of the currently logged in user
public void clearData()
{
//Clear all the data and save our work
SharedPreferences.Editor spEditor = localDatabase.edit();
spEditor.clear();
spEditor.commit();
}
}
联系方式。爪哇
public class Contact {
//Since the users id is auto incrementing in our database, we don't need to mention it here
//This name, email, username and password will store the value of the below name, email, username and password
String name , email , username , password;
int score;
//A constructor for signing up
public Contact(String name , String email , String username , String password)
{
this.name = name;
this.email = email ;
this.username = username;
this.password = password;
}
//A constructor for logging in
public Contact(String username , String password)
{
this.username = username;
this.password = password;
}
public Contact(String username , int score)
{
this.username = username;
this.score = score;
}
}
任何帮助都会很感激，也很抱歉发布这么大的代码块，我只是认为这会帮助人们了解代码。几天前我曾问过这个问题，但没有得到答案，所以我说我会对这个问题稍加改进，然后再次发布：）
