android 狀態欄操作

最近太忙了。好長時間沒動博客，把原來的東西拿出來都重新溫習下。

private void collapseStatusBar() {
        int currentApiVersion = android.os.Build.VERSION.SDK_INT;
        try {
            Object service = getSystemService("statusbar");
            Class statusbarManager = Class
                    .forName("android.app.StatusBarManager");
            Method collapse = null;
            if (service != null) {
                if (currentApiVersion <= 16) {
                    collapse = statusbarManager.getMethod("collapse");
                } else {
                    collapse = statusbarManager.getMethod("collapsePanels");
                }
                collapse.setAccessible(true);
                collapse.invoke(service);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
