是否可以在一项活动中附加超过 2 个 SlidingMenu 对象？由不同的按钮触发？
我的计划是有一个底部操作栏，所以我在屏幕的所有 4 个角落都有按钮。我希望它们中的每一个都能触发或切换具有不同内容的不同 SlidingMenu。
我已经有了前 2 个，但是我缺少后 2 个，因为当我尝试实例化它们时我没有错误，错误是当我.setMenu()在最后 2 个（底部）中调用方法时。
我打算做什么，可能吗？如果是，我该如何实现？
sMenuLeft = new SlidingMenu(this);
sMenuLeft.setMode(SlidingMenu.LEFT_RIGHT);
sMenuLeft.setTouchModeAbove(SlidingMenu.TOUCHMODE_NONE);
sMenuLeft.setShadowWidthRes(R.dimen.shadow_width);
sMenuLeft.setShadowDrawable(R.drawable.shadow);
sMenuLeft.setBehindOffsetRes(R.dimen.slidingmenu_100_offset);
sMenuLeft.setFadeEnabled(false);
sMenuLeft.setBehindScrollScale(0.0f);
sMenuLeft.attachToActivity(this, SlidingMenu.SLIDING_WINDOW);
sMenuLeft.setMenu(foo);
sMenuLeft.setSecondaryMenu(foo2);
sMenuRight = new SlidingMenu(this);
sMenuRight.setMode(SlidingMenu.LEFT_RIGHT);
sMenuRight.setTouchModeAbove(SlidingMenu.TOUCHMODE_NONE);
sMenuRight.setShadowWidthRes(R.dimen.shadow_width);
sMenuRight.setShadowDrawable(R.drawable.shadow_right);
sMenuRight.setBehindOffsetRes(R.dimen.slidingmenu_50_offset);
sMenuRight.setFadeEnabled(false);
sMenuRight.setBehindScrollScale(0.0f);
sMenuRight.attachToActivity(this, SlidingMenu.SLIDING_WINDOW);
sMenuRight.setMenu(foo3); // Error is here
sMenuRight.setSecondaryMenu(foo4); // And I suppose here as well
