禁用状态栏下拉菜单-API版本不同？

Question

很长一段时间以来，我一直在努力防止状态栏在我的应用程序中被拉下。

我已经在三星Galaxy S7 Edge上做到了这一点，并且工作正常！即使重新启动电话，它也可以重新工作。

但是，当我在三星Galaxy S6上对其进行测试时，此操作不起作用。状态栏会下拉，并在完全拉下后会保持下来。

我猜这是API版本不同的问题吗？

如果有人对此有任何类似的问题，请告诉我您是否找到了解决方案。

这是我用来防止状态栏下拉的代码。您将能够看到该条拉下然后立即关闭，这使用户无法与其进行交互：

// To keep track of activity's window focus
boolean currentFocus;

// To keep track of activity's foreground/background status
boolean isPaused;

Handler collapseNotificationHandler;

@Override
public void onWindowFocusChanged(boolean hasFocus) {

    currentFocus = hasFocus;

    if (!hasFocus) {

        // Method that handles loss of window focus
        collapseNow();
    }
}

public void collapseNow() {

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

    // If window focus has been lost && activity is not in a paused state
    // Its a valid check because showing of notification panel
    // steals the focus from current activity's window, but does not
    // 'pause' the activity
    if (!currentFocus && !isPaused) {

        // 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();
                }

                // Check if the window focus has been returned
                // If it hasn't been returned, post this Runnable again
                // Currently, the delay is 100 ms. You can change this
                // value to suit your needs.
                if (!currentFocus && !isPaused) {
                    collapseNotificationHandler.postDelayed(this, 1L);
                }

            }
        }, 1L);
    }
}

谢谢。
