我的抽屉布局中有两个抽屉（左右）（或开始和结束）。
问题是我似乎无法以编程方式关闭右抽屉..我可以打开或关闭左抽屉但只能打开右抽屉。
我正在做一些黑客让抽屉出现在动作栏上，所以我不确定这是不是问题..
在我的活动中，你会看到我正在呼叫一个＆＃34; showLanscapeMethod＆＃34;当设备配置更改为横向..这就是我要确保所有抽屉都关闭的地方..

private void showLandScape(){
actionBar.hide();
drawer.closeDrawer(right_drawer);//Doesn't work
drawer.closeDrawer(left_drawer);//works
drawer.closeDrawers();// only closes right
