android - 如何检测通知面板是否展开？

Question

我找到了扩展通知面板的方法

Object sbservice = getSystemService("statusbar");
Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
Method showsb;
if (Build.VERSION.SDK_INT >= 17) {
    showsb = statusbarManager.getMethod("expandNotificationsPanel");
} else {
    showsb = statusbarManager.getMethod("expand");
}
showsb.invoke(sbservice);

查看源代码后，我还发现了collapsePanels方法来折叠通知

但是我找不到任何方法来检测通知面板状态

因为我想检查它是打开还是关闭，然后决定应该打开它还是关闭它

我怎样才能知道这个状态？

虽然很晚了，但可能对某人有帮助

引用this

You can use below method for detecting the notification panel pull,

In your manifest file

<uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>

In your activity override the onWindowFocusChanged() and write the below code.

This uses the permission

@Override public void onWindowFocusChanged(boolean hasFocus) {
try
{
    if(!hasFocus)
    {
        Object service  = getSystemService("statusbar");
        Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
        Method collapse = statusbarManager.getMethod("collapse");
        collapse .setAccessible(true);
        collapse .invoke(service);
    }
}
catch(Exception ex)
{
    if(!hasFocus)
    {
        try {
            Object service  = getSystemService("statusbar");
            Class<?> statusbarManager = Class.forName("android.app.StatusBarManager");
            Method collapse = statusbarManager.getMethod("collapse");
            collapse .setAccessible(true);
            collapse .invoke(service);

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();                
        }
        ex.printStackTrace();
    }
} }
