我在SplashScreen活动中添加了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();
}
