android - ActionBar.NAVIGATION_MODE_TABS 使用時に SlidingMenu アイテムをクリックしたときにフラグメントを変更する方法

Question

検索しましたが、問題の正確な解決策が見つかりません。メインページャーがスワイプ可能なタブフラグメントをサポートできるようにする ActionBar.NAVIGATION_MODE_TABS を使用して MainActivity を備えたアプリがあります。メニュー（SlidingMenu）を開いてアイテムをクリックすると。メインのページャー レイアウト (タブを含む - フラグメント) を新しいフラグメント (またはレイアウト) に置き換える必要があります。たとえば、アプリを開くと、SMS、通話、スケジュール、ニュースの 4 つのタブが表示されます。SlidingMenu を開くと、Setting、Calendar、About の 3 つの項目があります。[設定] をクリックすると、古いコンテンツが新しいコンテンツに置き換えられます。これで、1 ページだけが表示されます。MainActivity.java の私のコード:
