Question

导航Activity

class NavigationActivity : AppCompatActivity(), NavigationView.OnNavigationItemSelectedListener {

private lateinit var appBarConfiguration: AppBarConfiguration

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_navigation)
    val toolbar: Toolbar = findViewById(R.id.toolbar)
    setSupportActionBar(toolbar)

    val fab: FloatingActionButton = findViewById(R.id.fab)
    fab.setOnClickListener { view ->
        Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
            .setAction("Action", null).show()
    }
    val drawerLayout: DrawerLayout = findViewById(R.id.drawer_layout)
    val navView: NavigationView = findViewById(R.id.nav_view)
    val navController = findNavController(R.id.nav_host_fragment)
    // Passing each menu ID as a set of Ids because each
    // menu should be considered as top level destinations.
    appBarConfiguration = AppBarConfiguration(
        setOf(
            R.id.nav_notes, R.id.nav_reminder, R.id.nav_archive,
            R.id.nav_deleted, R.id.nav_share, R.id.nav_send
        ), drawerLayout
    )
    setupActionBarWithNavController(navController, appBarConfiguration)
    navView.setupWithNavController(navController)
}

override fun onCreateOptionsMenu(menu: Menu): Boolean {
    // Inflate the menu; this adds items to the action bar if it is present.
    menuInflater.inflate(R.menu.navigation, menu)
    return true
}

override fun onSupportNavigateUp(): Boolean {
    val navController = findNavController(R.id.nav_host_fragment)
    return navController.navigateUp(appBarConfiguration) || super.onSupportNavigateUp()
}

override fun onNavigationItemSelected(p0: MenuItem): Boolean {

    when(p0.itemId) {
        R.id.nav_notes -> {
            HomeFragment()
        }
        R.id.nav_reminder -> {
            GalleryFragment()
        }
        R.id.nav_archive -> {
            SlideshowFragment()
        }
        R.id.nav_deleted -> {
            ToolsFragment()
        }
        R.id.nav_share -> {
            ShareFragment()
        }
        R.id.nav_send -> {
            SendFragment()
        }
        else -> {
            HomeFragment()
        }
    }

    drawer_layout.closeDrawer(GravityCompat.START)
    return true
}

}

当从一个片段导航到另一个片段时，我收到此错误。但它不会导致程序崩溃，但在创建复杂的布局层次结构时，它不会显示 xml 中的某些布局。那么如何解决这个错误所以这个错误的任何解决方案

Answer 1

这是 androidx.fragment 中的一个已知错误，已在 1.1.0-alpha07 和更新版本：https://issuetracker.google.com/issues/139349998. Ensure that you are on at least that version (instructions can be found here) 中修复。

Answer 2

我遇到了同样的错误，但就我而言，我没有使用 androidx。

我解决了它，将 Button 创建和 setOnClickListener 事件从 onCreate() 到 onCreateView() 方法。

希望对大家有所帮助，此致！
