推荐答案

下面是完整的解决方案。

here is the complete solution

//firstly when you register the user set the shared preferences in your register class like this
    //declare pref editor 
            SharedPreferences prefs; 
        SharedPreferences.Editor prefsEditor;
            prefs = PreferenceManager.getDefaultSharedPreferences(this);
        prefsEditor = prefs.edit();

    //paste below peace of code when the registration will be success

                     prefsEditor.putString("register", "yes");
                 prefsEditor.commit(); 

//now in your first activity you just check the shared pref value to know the user is register or no 


 SharedPreferences prefs;
String register;
prefs = PreferenceManager.getDefaultSharedPreferences(this);
        register=prefs.getString("register", "");
//now check the value of shared pref and apply the condition like this
Intent intent ;
    if(register.equalsIgnoreCase("yes"))
            {
                intent = new Intent(this, NextAct.class);
                startActivity(intent);
                finish();

            }
            else
            {
             intent = new Intent(this, Register.class);
                startActivity(intent);
                finish();
            }
