Question

我需要帮助。当我想打开 DrawableLayout 时，我第一次按下切换按钮时它没有响应。在我通过滑动打开 DrawableLayout 并将其关闭后，切换开始正常工作。这是问题的 Youtube link 和一些代码段。

kotlin 的片段class

//region Drawable layout
    private fun initDrawableLayout() {
        setUpNavigationView()
        setToolbar()
        setToggleActionBar()
    }

    private fun setUpNavigationView() {
        binding.mainNavView.bringToFront()
        binding.mainNavView.setNavigationItemSelectedListener(this)
    }

    private fun setToggleActionBar() {
        var toggle = ActionBarDrawerToggle(
            this,
            binding.mainDrawerLayout,
            binding.mainToolbar,
            R.string.navigation_drawer_open,
            R.string.navigation_drawer_close
        )
        binding.mainDrawerLayout.addDrawerListener(toggle)
        toggle.syncState()
    }

    private fun setToolbar() {
        binding.toolbarTitleTv.text = getString(R.string.home)
    }

在我的例子中，我需要从 xml 文件中的 NavigationView 中删除 visibility = gone。也许它会对某人有所帮助。

<com.google.android.material.navigation.NavigationView
        android:id="@+id/main_nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:visibility="gone"
        app:headerLayout="@layout/header"
        app:menu="@menu/drawable_menu" />
