有没有办法检查状态栏的可见性？

Question

我有一项服务应定期检查状态栏的可见性,当全屏模式下某些顶级活动是(或不是)时.可能吗？

最后,我发现了如何检查状态栏是否可见.它有点像黑客,但它对我有用.我在我的服务中创建了该方法:

private void createHelperWnd() {
        WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
        final WindowManager.LayoutParams p = new WindowManager.LayoutParams();
        p.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;
        p.gravity = Gravity.RIGHT | Gravity.TOP;
        p.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
        p.width = 1;
        p.height = LayoutParams.MATCH_PARENT;
        p.format = PixelFormat.TRANSPARENT;
        helperWnd = new View(this); //View helperWnd;

        wm.addView(helperWnd, p);
        final ViewTreeObserver vto = helperWnd.getViewTreeObserver();
        vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

            @Override
            public void onGlobalLayout() {

                if (heightS == helperWnd.getHeight()) {
                    isFullScreen = true;
                } else {
                    isFullScreen = false;
                }
            }
        });

    }

其中widthS和heightS是我们的全局屏幕尺寸; 在这里,我只是将隐形辅助窗口高度与屏幕高度进行比较,并确定状态栏是否可见.并且不要忘记在服务的onDestroy中删除helperWnd.
