当我从导航抽屉中选择任何选项时，什么都没有发生。一旦我点击导航抽屉，抽屉就会关闭。如果您想从那里进行更正，我也会添加我的Github repo链接。https://github.com/tanmay380/andorid-studio-
这是我的AlphabetBaseShow类，它显示导航抽屉（我将删除一些行，以便使用更少的空间）

P.S。：-请不要删除此问题。我的最后一个问题已删除，因为它没有太多信息。如果是这种情况，也请给我发邮件：-tanmaysinghal @ 380 @ gmail.com或发表评论否则，我必须等待1周才能重新发布问题。

为您的仓库创建了一个拉取请求。签出。
ps.s。-您应该使用相同版本的支持和设计库-不要使用System.gs（！）-您的导航项Click侦听器不起作用的主要原因是-您未分配接口实现
navigationView.setNavigationItemSelectedListener(this);
代替
navigationView.setNavigationItemSelectedListener(new OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
//some stuff here
}
});
已经实现了接口NavigationView.OnNavigationItemSelectedListener
我只需要将NAVIGATIONDRAWER部分放在最后
