什么是跳过活动的最佳方式 [英] What's the best way to skip an Activity

问题描述

我正在开发中，在他的仪表盘上的用户登录，直到他注销（我的意思是，如果应用程序被关闭并重新启动，他仍然保持登录）保持记录在一个应用程序。我使用共享preferences 来检查，如果用户在实际登录。

I'm developing an app in which a user logs in to his dashboard and stays logged in until he logs out (I mean if the app is closed and restarted, he still stays logged in). I'm using SharedPreferences to check if the user is actually logged in.

preference.java

public class Preference {

    Context context;
    SharedPreferences sharedPref;

    public Preference(Context context){
        this.context = context;
        sharedPref = context.getSharedPreferences("LoginState", 0);
    }

    public boolean getIsLoggedIn(){
        return sharedPref.getBoolean("State", false);
    }

    public void setIsLoggedIn(boolean state){
        SharedPreferences.Editor editor = sharedPref.edit();
        editor.putBoolean("State", state);
        editor.commit();
    }

}

我调用该函数的用户 setIsLoggedIn（真）时，在用户登录和 setIsLoggedIn（假）时注销。但如何检查和跳过LoginActivity如果用户已经登录？

I call the function setIsLoggedIn(true) when the user logs in and setIsLoggedIn(false) when the user logs out. But how to check and skip the LoginActivity if the user is already logged in?

推荐答案

将这种情况在闪屏

Preference pre = new Preference(SplashScreen.this);
    if(preference.getIsLoggedIn()){
    // move to Login Screen
    }else{
     // move to your mainscreen
    }
