如何关闭应用程序？
我有一个启动屏幕，其中有一些代码我只想调用一次，因此在显示启动屏幕后，它会转到我的主游戏，并且我不希望它再次返回启动屏幕，直到游戏再次启动。但是当我返回主屏幕时，它又回到初始屏幕。当从主屏幕按下后退按钮而不是返回到初始屏幕时，如何使游戏关闭？
这是我现在在主游戏中所拥有的内容，但它仍然可以追溯到飞溅......
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
Toast.makeText(getApplicationContext(),"back was pressed",Toast.LENGTH_LONG).show();
finish();
return true;
}
return super.onKeyDown(keyCode, event);
}
i have a splash screen that has some code that i only want called once so after showing the splash screen it goes to my main game, and i don't want it going back to the splash screen again until the game is launched again. but when i hit back on my main screen, it goes back to the splash screen. how do i make the game close when the back button is pressed from the main screen instead of going back to the splash screen?
here is what i have right now on my main game, but it still goes back to the splash...
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
Toast.makeText(getApplicationContext(),"back was pressed",Toast.LENGTH_LONG).show();
finish();
return true;
}
return super.onKeyDown(keyCode, event);
}

在执行
startActivity()后立即在启动活动中调用finish():)Call
finish()in the splash activity right after you dostartActivity():)如果您要启动活动，则可以使用 FLAG_ACTIVITY_NO_HISTORY。请参阅此以获取参考。我相信如果这是您的初始活动，您也可以以某种方式做同样的事情。
If you are starting the Activity you can use FLAG_ACTIVITY_NO_HISTORY. See this for a reference. I'm sure you can do the same somehow if it is your initial activity.
您可以在 Splash 活动的 onResume 方法中调用
finish()。杰克的解决方案可能是最好的。You could put a call to
finish()in your onResume method for the Splash activity. Jack's solution is probably best though.
