}

當我LiveActivity單擊硬件後退按鈕，回MainActivity但我的幻燈片菜單也打開了，我怎麼能隱藏他們，當我點擊硬件後退按鈕？

如果您碰巧使用https://github.com/jfeinstein10/SlidingMenu，我建議您改用NavigationDrawer代替，因爲該SlidingMenu不再維護並且存在尚未解決的錯誤。如果您堅持使用該庫，我建議你通過調用

if (menu.isMenuShowing()) { 
    menu.showContent(); 
}

感謝您的回答，但我仍然從這個錯誤，我不知道爲什麼它不工作，它太壞 –

請確保滑動菜單實例是正確的。把'private SlidingMenu menu'放在方法外部作爲一個全局變量，然後將其正確地實例化爲'menu = new SlidingMenu（this）;'在Menu（）方法內部。確保你刪除了'final'關鍵字 – HendraWD

它對我的工作！非常感謝你我只是忘了刪除「最終」!!!!! –

關閉菜單前轉到LiveActivity您可以通過方式解決此問題：

移動SlidingMenu menu全局變量
覆蓋活動方法onBackPressed你想單擊後退硬鍵來關閉幻燈片菜單如下代碼波紋管： @Override public void onBackPressed() { super.onBackPressed(); if (menu.isMenuShowing()) { menu.toggle(); } }

感謝您的回答，但是當我移動SlidingMenu菜單中的全局變量，它給了我展示了java.lang.RuntimeException的錯誤：無法實例活動ComponentInfo {bravoideas.ishowlife/bravoideas.ishowlife.LiveActivity}：java.lang中。 NullPointerException異常：嘗試調用虛擬方法android.content.res.Resources android.content.Context.getResources（）'空對象 –

在你的init''菜單=新SlidingMenu（本）;對''''OnCreate' '方法？ rememer刪除最後的關鍵字 –

哦是的！我忘了刪除「最終」！非常感謝 –
