我不希望该应用程序像在WhatsApp上一样在SplashScreen中按下主页时运行MainAct

我在SplashScreen活动中放了onPause来覆盖MainActivity，但是它不起作用。而且我已经搜索了互联网，但仍然找不到该怎么做的方法。即使我按下主页按钮，它也总是启动MainActivity

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

    Thread splashScreenThread = new Thread() {
        @Override
        public void run() {
            try {
                sleep(2000);
                super.run();
            } catch (InterruptedException e) {
                Log.e(this.getClass().getSimpleName(), "showSplashScreen: " + e.getMessage());
            } finally {
                Intent moveToHomeActivityIntent = new Intent(SplashScreenActivity.this, HomeActivity.class);
                startActivity(moveToHomeActivityIntent);
                finish();
            }
        }
    };
    splashScreenThread.start();
}

@Override
protected void onPause(){
    super.onPause();
    finish();
}
