在Android Studio中的NavigationDrawer中单击项

Question

我知道这个问题很常见，但我真的很困惑如何将onClickListener应用到我的navigationDrawer项目中，我有两个项目，即编辑配置文件和注销。如果选择了其中一个项目，我只想进行Toast或打印。是否有人可以帮助我，我已经在互联网上搜索过了，但还没有找到onClickListener，需要帮助

我想我的主活动中缺少了一个

OnCreate（）主活动

    setContentView(R.layout.dashboard_main);
    DrawerLayout drawerLayout = findViewById(R.id.drawerlayout);
    NavigationView navigationView = (NavigationView) findViewById(R.id.navigationview);

侧菜单。xml

Answer 1

首先，您需要实现NavigationView。活动上的OnNavigationItemSelectedListener界面
然后在onCreate（）方法上键入navigationView。setNavigationItemSelectedListener（此）；在此之后，重写onNavigationItemSelected方法
在这里，您可以使用此示例代码。

 @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        if (item.getItemId() == R.id.editProfile)
        {
         //edit your profile
        }
        else if (item.getItemId() == R.id.logout)
        {
              //log out
        }
        return false;
    }
