重写onNavigationItemSelected将停止导航组件在单击项时打开片段的功能,而是调用onNavigationItemSelected,而不执行其他操作。
创建时调用了导航视图设置
private fun setupNavigationDrawer(){
NavigationUI.setupWithNavController(binding.navigationView,navHostFragment.findNavController())
binding.navigationView.setNavigationItemSelectedListener(this)
}
活性
class MainActivity : AppCompatActivity(),NavigationView.OnNavigationItemSelectedListener
导航项目选定
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
}

我已将菜单项ID设置为导航片段ID,并且它在未设置onNavigationItemSelected的情况下工作。我还在XML中的片段容器下方具有导航视图
我试过
- 更改onNavigationItemSelected的返回值-在setupWithNavController之前设置onNavigationItemSelected侦听器,这会导致根本不调用侦听器

最后我通过手动打开碎片来解决它
