重写onNavigationItemSelected停止导航到片段的项目点击在drawerLayout

Question

重写onNavigationItemSelected会停止导航组件在项目点击时打开片段的功能，取而代之的是调用onNavigationItemSelected，其他什么都不发生

导航视图设置调用在创建

private fun setupNavigationDrawer(){
NavigationUI.setupWithNavController(binding.navigationView,navHostFragment.findNavController())
binding.navigationView.setNavigationItemSelectedListener(this)

}

活动

class MainActivity : AppCompatActivity(),NavigationView.OnNavigationItemSelectedListener

onNavigationItemSelected

override fun onNavigationItemSelected(item: MenuItem): Boolean {
if(binding.mainActivityRootView.isDrawerOpen(GravityCompat.END)){
binding.mainActivityRootView.closeDrawer(GravityCompat.END)
}
else if(binding.mainActivityRootView.isDrawerOpen(GravityCompat.START)){
binding.mainActivityRootView.closeDrawer(GravityCompat.START)
}
return true
}

导航视图xml

<com.google.android.material.navigation.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:menu="@menu/menu_home_navigation_drawer"
android:paddingStart="15dp"
android:paddingEnd="15dp"
app:headerLayout="@layout/layout_navigation_drawer_header"
app:itemIconTint="@color/lipstick"
android:layout_gravity="end"
app:drawerLayoutCornerSize="10dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" >
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="bottom"
android:layout_marginBottom="40dp"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_main_blue"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:tint="@color/lipstick" />
<TextView
android:id="@+id/textView41"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="@font/montserratmedium"
android:text="Version IMPLEMENT"
android:textColor="@color/pinkish_grey"
android:textSize="10sp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>
</com.google.android.material.navigation.NavigationView>

我已经将菜单项id设置为导航片段id，它可以在没有onNavigationItemSelected的情况下工作，我也有导航视图下面的片段容器在xml

i tried to

-change返回值onNavigationItemSelected-在setupWithNavController之前设置onNavigationItemSelected监听器，这会导致监听器根本不会被调用

Answer 1

最后我通过手动打开fragments解决了这个问题

从

override fun onNavigationItemSelected(item: MenuItem): Boolean {
if(binding.mainActivityRootView.isDrawerOpen(GravityCompat.END)){
binding.mainActivityRootView.closeDrawer(GravityCompat.END)
}
else if(binding.mainActivityRootView.isDrawerOpen(GravityCompat.START)){
binding.mainActivityRootView.closeDrawer(GravityCompat.START)
}
return true
}

override fun onNavigationItemSelected(item: MenuItem): Boolean {
if(binding.mainActivityRootView.isDrawerOpen(GravityCompat.END)){
binding.mainActivityRootView.closeDrawer(GravityCompat.END)
}
else if(binding.mainActivityRootView.isDrawerOpen(GravityCompat.START)){
binding.mainActivityRootView.closeDrawer(GravityCompat.START)
}
when(item.itemId){
else ->{
NavigationUI.onNavDestinationSelected(item,navHostFragment.findNavController())
}
}
return true
}
