Java 退出应用程序时出现启动屏幕活动

每当我尝试按两次后退按钮退出我的应用程序时，启动屏幕就会出现，并且它会冻结，直到我再次按后退按钮。所以我需要按下后退按钮三次才能退出我的应用程序。请帮助我退出应用程序，只需按两次后退按钮

项目中的java代码如下所示：

public void onBackPressed()
{
    if (doubleBackToExitPressedOnce)
    {
        super.onBackPressed();
        MapsActivity.this.finish();
    }

    this.doubleBackToExitPressedOnce = true;
    Toast.makeText(this, "Please click Back again to exit", Toast.LENGTH_SHORT).show();

    new Handler().postDelayed(new Runnable()
    {
        @Override
        public void run()
        {
            doubleBackToExitPressedOnce = false;
        }
    }, 2000);
}

public class SplashScreen extends AppCompatActivity {
    ImageView logoView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);
        Animation anim1 = AnimationUtils.loadAnimation(this,R.anim.anim_down);
        logoView = findViewById(R.id.logoview);
        logoView.setAnimation(anim1);


        Handler handler = new Handler();

        handler.postDelayed(new Runnable()
        {
            @Override
            public void run()
            {
                Intent next_scrn = new Intent(SplashScreen.this,MapsActivity.class);
                startActivity(next_scrn);
                overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
            }
        },2500);
    }
}

我的启动屏幕代码如下：

public void onBackPressed()
{
    if (doubleBackToExitPressedOnce)
    {
        super.onBackPressed();
        MapsActivity.this.finish();
    }

    this.doubleBackToExitPressedOnce = true;
    Toast.makeText(this, "Please click Back again to exit", Toast.LENGTH_SHORT).show();

    new Handler().postDelayed(new Runnable()
    {
        @Override
        public void run()
        {
            doubleBackToExitPressedOnce = false;
        }
    }, 2000);
}

public class SplashScreen extends AppCompatActivity {
    ImageView logoView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);
        Animation anim1 = AnimationUtils.loadAnimation(this,R.anim.anim_down);
        logoView = findViewById(R.id.logoview);
        logoView.setAnimation(anim1);


        Handler handler = new Handler();

        handler.postDelayed(new Runnable()
        {
            @Override
            public void run()
            {
                Intent next_scrn = new Intent(SplashScreen.this,MapsActivity.class);
                startActivity(next_scrn);
                overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
            }
        },2500);
    }
}

您应该在开始新活动后完成Splash活动，因此请使用：

handler.postDelayed(new Runnable()
    {
        @Override
        public void run()
        {
            Intent next_scrn = new Intent(SplashScreen.this,MapsActivity.class);
            startActivity(next_scrn);
            overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
            SplashScreen.this.finish();
        }
    },2500);

            SplashScreen.this.finish();
        }
    },2500);

添加

finish（）在下面的代码之后

  Intent next_scrn = new Intent(SplashScreen.this,MapsActivity.class);
  startActivity(next_scrn);

添加
finish（）在下面的代码之后

  Intent next_scrn = new Intent(SplashScreen.this,MapsActivity.class);
  startActivity(next_scrn);

您必须完成（）启动屏幕，如下所示，而不是按您的条件进行反压操作

  Intent next_scrn = new Intent(SplashScreen.this,MapsActivity.class);
            startActivity(next_scrn);
            overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
            finish();

            finish();

MapsActivity.this.finish（）并从
SplashScreen
活动中添加
finish（）
