Oreo中的Android隐藏和禁用通知（状态）栏

Question

通过禁用状态栏的单击和单击来为应用程序设置信息亭的方法在android 8上不起作用。如上如何在Android中禁用状态栏的单击和下拉菜单所述？ 。

我已经在android 7及更低版本上对其进行了测试，并且可以正常工作，但是在android 8上将其拉出时，状态栏仍然会拉低。

我没有找到相同的任何解决方案。 请让我知道是否有适用于oreo的解决方案。

谢谢！

我在MainActivity使用以下代码。

//Global Declaration
Handler collapseNotificationHandler;

@Override
    public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    Log.d(tag, "window focus changed");

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        collapseNow();
    }
}

收合方法

public void collapseNow() {

    try {
        // Initialize 'collapseNotificationHandler'
        if (collapseNotificationHandler == null) {
            collapseNotificationHandler = new Handler();
        }

        // Post a Runnable with some delay - currently set to 300 ms
        collapseNotificationHandler.postDelayed(new Runnable() {

            @Override
            public void run() {

                // Use reflection to trigger a method from 'StatusBarManager'
                Object statusBarService = getSystemService("statusbar");
                Class<?> statusBarManager = null;

                try {
                    statusBarManager = Class.forName("android.app.StatusBarManager");
                } catch (ClassNotFoundException e) {
                    e.printStackTrace();
                }

                Method collapseStatusBar = null;
                try {
                    // Prior to API 17, the method to call is 'collapse()'
                    // API 17 onwards, the method to call is `collapsePanels()`
                    if (Build.VERSION.SDK_INT > 16) {
                        collapseStatusBar = statusBarManager.getMethod("collapsePanels");
                    } else {
                        collapseStatusBar = statusBarManager.getMethod("collapse");
                    }
                } catch (NoSuchMethodException e) {
                    e.printStackTrace();
                }

                collapseStatusBar.setAccessible(true);

                try {
                    collapseStatusBar.invoke(statusBarService);
                } catch (IllegalArgumentException e) {
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                } catch (InvocationTargetException e) {
                    e.printStackTrace();
                }
                // Currently, the delay is 10 ms. You can change this
                // value to suit your needs.
                collapseNotificationHandler.postDelayed(this, 10L);
            }
        }, 10L);
    } catch (Exception e) {
        e.printStackTrace();
    }
}
