为什么当使用WindowCompat.setDecorFitsSystemWindows(window，false时滚动不能正常工作)？

看上去就像当我加上
WindowCompat.setDecorFitsSystemWindows(window, false)对于我的Android应用程序来说，当键盘打开时，滚动屏幕上的内容就会被破坏。它不允许您滚动到屏幕上的最后一项。这是我正在使用的代码。
package com.example.myapplication
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.core.view.WindowCompat
import com.example.myapplication.databinding.ActivityMainBinding
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
WindowCompat.setDecorFitsSystemWindows(window, false)
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
}

</manifest>正确(当键盘打开时，我可以一直滚动到6)
错误(我只能在打开键盘时滚动到4)
是什么导致了这一切？这似乎是一个非常简单的用例。

弄明白了。我需要在它们改变的时候更新它们。见代码。
package com.example.myapplication
import android.os.Bundle
import android.view.View
import android.view.ViewGroup
import android.view.WindowInsets
import androidx.appcompat.app.AppCompatActivity
import androidx.core.view.WindowCompat
import androidx.core.view.updateLayoutParams
import androidx.core.view.updateMargins
import com.example.myapplication.databinding.ActivityMainBinding
class MainActivity : AppCompatActivity() {
private lateinit var binding: ActivityMainBinding
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
WindowCompat.setDecorFitsSystemWindows(window, false)
binding = ActivityMainBinding.inflate(layoutInflater)
setContentView(binding.root)
binding.root.setOnApplyWindowInsetsListener { _, _ ->
applyKeyboardInsets(binding.root)
}
}
private fun applyKeyboardInsets(root: View): WindowInsets {
val insets = root.rootWindowInsets.getInsets(WindowInsets.Type.ime())
root.updateLayoutParams<ViewGroup.MarginLayoutParams> {
updateMargins(insets.left, insets.top, insets.right, insets.bottom)
}
return WindowInsets.Builder()
.setInsets(WindowInsets.Type.ime(), insets)
.build()
}
