Android Studio 中的入职屏幕

Question

我正在尝试构建一个 OnboardingActivity 并且我也已经实现了它，但现在我希望它应该对新用户可见或每个用户一次可见，我尝试了共享首选项，但没有效果。 我使用 Splash Screen 作为 Launcher Activity 和 MainActivty & onboardingActivity 作为下一个意图。

SplashActivity

import android.content.Intent;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Bundle;

import android.content.Intent;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.WindowManager;

public class SplashActivity extends AppCompatActivity {


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);
    getSupportActionBar().hide();


    Thread myThread = new Thread() {
        @Override
        public void run() {
            try {
                sleep(3000);
                Intent intent = new Intent(getApplicationContext(), OnBoardActivity.class);
                startActivity(intent);
                finish();

            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    };
    myThread.start();
}
}

OnBoardActivity

import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.Color;
import android.os.Bundle;


import com.hololo.tutorial.library.Step;
import com.hololo.tutorial.library.TutorialActivity;


public class OnBoardActivity  extends TutorialActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
 SharedPreferences preferences =  getSharedPreferences("my_preferences", 
 MODE_PRIVATE);

 // Check if onboarding_complete is false 
 if(!preferences.getBoolean("onboarding_complete",false)) {
// Start the onboarding Activity
Intent onboarding = new Intent(this, OnBoardActivity.class);
startActivity(onboarding);

// Close the main Activity
finish();
return;
}

//slide1
    addFragment(new Step.Builder().setTitle("WELCOME.NAMASTE!!")
            .setSummary("It seems like you are a New User!!\nWe welcome you 
to GFeed.")
            .setBackgroundColor(Color.parseColor("#FFA600")) // int 
background color
            .setDrawable(R.drawable.gh) // int top drawable

            .build());
    //slide2
    addFragment(new Step.Builder().setTitle("CAREER ORIENTED")
            .setSummary("This app includes some awesome career oriented 
    elements such as Internship,different courses related to CS/IT,career 
   tips by experts.")
            .setBackgroundColor(Color.parseColor("#FFA600")) // int 
   background color
            .setDrawable(R.drawable.human) // int top drawable

            .build());
    //slide3
    addFragment(new Step.Builder().setTitle("COLLEGE ORIENTED")
            .setSummary("This app includes some awesome college oriented 
    elements such as college club news,aktu feed,H.O.D'corner and Gsim")
            .setBackgroundColor(Color.parseColor("#FFA600")) // int 
    background color
            .setDrawable(R.drawable.college) // int top drawable

            .build());
   }

  @Override
 public void finishTutorial() {

  SharedPreferences preferences =
        getSharedPreferences("my_preferences", MODE_PRIVATE);

 // Set onboarding_complete to true
 preferences.edit()
        .putBoolean("onboarding_complete",true).apply();

 // Launch the main Activity, called MainActivity
 Intent main = new Intent(this, MainActivity.class);
 startActivity(main);

 // Close the OnboardingActivity
 finish();
   }
 }

Answer 1

在OnboardActivity 中，您正在检查入职是否未完成以开始相同的活动。
逻辑应该是相反的，检查入职是否完成并开始MainActivity：

if(preferences.getBoolean("onboarding_complete",false)) {
    // Start Main Activity
    Intent intent = new Intent(this, MainActivity.class);
    startActivity(intent);

    // Close Onboarding
    finish();
    return;
}

因此，如果入职未完成，您可以继续进行相同的活动。
还要检查是否正在调用方法finishTutorial。

Answer 2

我添加了我的 mainactivity，它对我有用。

  SharedPreferences sharedPreferences = getSharedPreferences("prefs", MODE_PRIVATE);
                Boolean firstStart = sharedPreferences.getBoolean("firstStartBoarding", true);
                if (firstStart) {
                    firstRun();
                }

public void firstRun() {
            Intent intent = new Intent(AddWordActivity.this, OnBoardingActivity.class);
            startActivity(intent);
        
                SharedPreferences sharedPreferences = getSharedPreferences("prefs", MODE_PRIVATE);
                SharedPreferences.Editor editor = sharedPreferences.edit();
        
                editor.putBoolean("firstStartBoarding", false);
                editor.apply();
            }
