Android 如何关闭导航抽屉

*我正在开发一个应用程序，其中我使用了旧的导航抽屉模式。我的问题是，当我按下“后退”按钮时，导航抽屉将出现，而不是以前的活动。我认为我没有关闭导航抽屉，我真的不知道如何关闭导航抽屉。所以，请帮我摆脱这一切。谢谢

您是否为NavDrawer实施了

ActionBarDrawerToggle

？ 您可以将其分配给NavDrawer并将其设置为

syncState（）

后续行动： 以及以下代码，用于在转到其他活动时关闭NavDrawer：

mBaseDrawerLayout.closeDrawer(mBaseDrawerList);
mBaseDrawerToggle.syncState();

请发布您的代码，以便有人可以帮助您。引用此链接“旧”导航抽屉模式是否有打开和关闭方法的侦听器？@anopll我已共享此代码。请检查此项。请发布您的代码，以便有人可以帮助您。引用此链接不是“旧”导航抽屉模式导航抽屉模式是否有打开和关闭方法的侦听器？@anopll我已共享了代码。请检查这一点。我没有使用片段，导航抽屉对每个活动都有单独的代码。很好。这段代码（处理NavDrawer的方法）依赖于片段或任何东西。当用户导航到另一个活动（通过Intent）或触摸ActionBar上的NavDrawer开关时，您只需处理关闭状态。因此，我必须关闭使用Intent调用下一个活动的抽屉next activity。是的。你调用“closeDrawer”并同步DrawerToggle状态。我没有使用片段，导航抽屉对每个活动都有单独的代码。没关系。这段代码（处理NavDrawer的方法）依赖于片段或任何东西。当用户导航到另一个活动（通过Intent）或触摸ActionBar上的NavDrawer开关时，您只需处理关闭状态。因此，我必须关闭使用Intent调用下一个活动的抽屉next activity。是的。调用“closeDrawer”并同步抽屉切换状态。
