我在应用中添加了导航视图和抽屉布局。当我打开和关闭抽屉时，它会滞后。慢慢打开和关闭。我也在6.0版本中突出显示了这个问题，但不像4.4那样突出。导航抽屉需要时间打开和关闭
当我4.4设备上运行，我打开我注意到日志消息太多的工作可以在主线程上做抽屉。
所以，我想评论的所有代码，除了导航抽屉和选项菜单代码。所以之后我发现它工作得很好。
这是问题吗？或者一些内存问题可以在那里？但在更大的存储设备上，我也发现了这个问题。
我需要为其他代码另一个活动？这样抽屉工作会更快吗？
我也试图创建一个片段并且在主活性的FrameLayout代替它以分离的代码。但它仍然滞后。
如果我创建新的活动我仍然需要在该活动的所有导航代码，这将是再次同样的事情。
我不明白可能是什么问题。任何人都可以请帮助..谢谢..

你必须把你的'FrameLayout'里面的'LinearLayout'和下面的' ToolBar'。因为'DrawerLayout'只包含两个主布局。 – Ironman
