Android--NavigationView+DrawerLayout实现侧滑（仿QQ）

1、首先导包

首先在主布局文件中使用DrawerLayout作为外包装，里面包含一个主页面和侧滑的菜单页面，而侧滑菜单页面用NavigationView实现，drawerLayout中包含了主页面和侧滑的菜单页面：

思考如何关闭手势滑动？NavigationView的确没有相关关闭侧滑手势的属性，但是别忘了，drawerLayout却可以，通过以下属性可以关闭滑动手势操作：
在android抽屉开发中，需要关闭手势滑动，来滑出弹出框

mDrawer_layout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED)//关闭手势滑动

mDrawer_layout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);//打开手势滑动

NavigationView Item图标不显示原始颜色解决办法：

navigationView.setItemIconTintList(null);
