切换菜单按钮不会打开滑动菜单并关闭应用程序
Toggle menu Button doesn't open sliding menu and shuts down app
我在我的应用程序中包含了 DrawerLayout。我在其中添加了工具栏和 "home button"。除了工具栏左侧的 "menu button" 之外，滑动菜单工作正常。问题是，当我点击它时，我的应用程序无故关闭。我不知道为什么它会关闭。它应该打开隐藏的滑动菜单。如果我从左向右滑动此菜单会显示，但当单击按钮时它会立即关闭所有应用程序。
下面是我的菜单XML代码：

将您的 setUpActionBarDrawerToggle 替换为以下内容并检查
private void setUpActionBarDrawerToggle()
