抽屉导航菜单点击监听器不工作如何解决这个问题

Question

抽屉导航工作正常，但当单击某个项目时，不会生成任何事件，导航也会终止。我应该使用哪个事件侦听器？我想通过单击图像视图来使用抽屉导航。抽屉导航打开成功，但打开后单击菜单时，不会生成单击事件，导航将终止。我们如何解决这个问题？

R.id.menu2 -> {
Toast.makeText(this@test,"dddddd", Toast.LENGTH_SHORT).show()

Answer 1

您必须在onCreate方法中使用此行

binding.navview.setNavigationItemSelectedListener(this)

所以你的onCreate函数看起来像这个

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.layout_test)
binding = LayoutTestBinding.inflate(layoutInflater)
setContentView(binding.root)
binding.navview.setNavigationItemSelectedListener(this)
binding.menu.setOnClickListener {
binding.drawerLayout.openDrawer(GravityCompat.END)
}
}

它会起作用的。
