菜单项点击不工作我尝试了各种各样的东西，但它没有工作。
以下是我的代码：

当我尝试将activity_home.xml视为设计时，它不会显示左抽屉，但是当我在设备上安装应用程序时，它会在点击时显示左抽屉但是当我点击任何时候它都不会显示检查框而且没有工作。

这是解决此问题的简单解决方案。您可以将HomeActivity方法链接到菜单项（无论您想要哪个）。现在只需创建方法并转到菜单布局。在菜单布局中，只需在item标签内添加android：onClick，并将特定的方法名称放在其中。你完成了。如果这有用，请告诉我。

更新这些代码行对我有用..更新后清理并重建Project。
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.bringToFront();
