我的项目中有两个活动ActivityOne，MainActivity. 我开始MainActivity使用意图，ActivityOne然后我在活动中切换暗模式开关MainActivity并调用recreate()活动。但重新创建时在线MainActivity崩溃。super.onCreate(savedInstanceState)
androidx片段版本：1.2.5
生命周期版本：2.2.0
主要活动：
override fun onCreate(savedInstanceState: Bundle?) {
val userInterfaceMode = when (UIMode.currentUIMode) {
is UIMode.DarkMode -> AppCompatDelegate.MODE_NIGHT_YES
is UIMode.LightMode -> AppCompatDelegate.MODE_NIGHT_NO
else -> AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM
}
AppCompatDelegate.setDefaultNightMode(userInterfaceMode)
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
overridePendingTransition(
R.anim.enter_activity_fade_in_anim,
R.anim.enter_activity_fade_out_anim
)
if (savedInstanceState == null){
setupNavigation()
}
}
override fun onRestoreInstanceState(savedInstanceState: Bundle) {
super.onRestoreInstanceState(savedInstanceState)
setupNavigation()
}
private fun setupNavigation(){
if (supportFragmentManager.findFragmentByTag(NAV_HOST_TAG) != null){
val host = supportFragmentManager
.findFragmentByTag(NAV_HOST_TAG) as NavHostFragment
supportFragmentManager
.beginTransaction()
.attach(host)
.setPrimaryNavigationFragment(host)
.commit()
}else{
val host = NavHostFragment.create(R.navigation.navigation_graph)
supportFragmentManager
.beginTransaction()
.add(
R.id.mainActivityRoot, host,
NAV_HOST_TAG
)
.setPrimaryNavigationFragment(host)
.commit()
}
}
