Java android onCreate 总是调用

Question

当我锁定手机并在一个 Activity 中解锁时始终调用 onCreate 时，我遇到了问题。也许有人可以帮助我？这是我的onCreate，也许我做错了什么，调用了onCreate。当我第一次使用应用程序以及解锁手机时，创建时会在我的应用程序中调用，但是当我最小化我的应用程序并打开应用程序时，我的应用程序会调用 onResume

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

        MainActivity.logOut = true;
//        i = new Intent(getApplicationContext(), Sync.class);
//        startService(i);
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
        columns.add("nazwa");

Answer 1

我更改了我的 list :我添加了以下内容:android:configChanges="orientation|keyboardHidden|screenSize" 因为:

要声明您的 Activity 处理配置更改，请编辑 list 文件中的相应元素，以包含 android:configChanges 属性，该属性的值表示您要处理的配置。 android:configChanges 属性的文档中列出了可能的值(最常用的值是“orientation”，以防止在屏幕方向更改时重新启动，以及“keyboardHidden”以防止在键盘可用性更改时重新启动)。您可以在属性中声明多个配置值，用管道 | 分隔它们。性格。
