Question

我是开发Android应用程序的新手，我正在尝试检查会话是否已登录，如果用户已登录，则不应显示启动画面，但用户未登录，则应显示启动屏幕为3秒。

但是Splash屏幕一直在显示，所以我认为我做错了If / Else的事情，希望有人能帮助我：）

public class SplashScreen extends Activity {

    // Splash screen timer
    private static int SPLASH_TIME_OUT = 3000;
    private SessionManager session;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Session manager
        session = new SessionManager(getApplicationContext());

        // Check if user is already logged in or not
        if (session.isLoggedIn()) {
            // User is already logged in. Take him to main activity
            new Handler().postDelayed(new Runnable() {

            /*
             * Showing splash screen with a timer. This will be useful when you
             * want to show case your app logo / company
             */

                @Override
                public void run() {
                    // This method will be executed once the timer is over
                    // Start your app login activity
                    Intent i = new Intent(SplashScreen.this, LoginActivity.class);
                    startActivity(i);

                    // close this activity
                    finish();
                }
            }, SPLASH_TIME_OUT); } else {
            setContentView(R.layout.splash_screen);
        }

    }
}

我自己修改了这段代码：

public class SplashScreen extends Activity {

// Splash screen timer
private static int SPLASH_TIME_OUT = 3000;
private SessionManager session;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Session manager
    session = new SessionManager(getApplicationContext());

    // Check if user is already logged in or not
    if (session.isLoggedIn()) {
        // User is already logged in. Take him to main activity

        Intent i = new Intent(SplashScreen.this, MainActivity.class);
        startActivity(i);

        // close this activity
        finish();

    } else {

        setContentView(R.layout.splash_screen);
        new Handler().postDelayed(new Runnable() {

        /*
         * Showing splash screen with a timer. This will be useful when you
         * want to show case your app logo / company
         */

            @Override
            public void run() {

                Intent i = new Intent(SplashScreen.this, LoginActivity.class);
                startActivity(i);

                // close this activity
                finish();
            }
        }, SPLASH_TIME_OUT);
    }
}
}
