是否在XML文件中为TextView设置了ID？只有具有ID的视图才会自动还原其状态。此外，如果要重写onSaveInstanceState（...）和/或onRestoreInstanceState（...），请不要忘记从调用超类的方法开始：

super.onSaveInstanceState(...);

super.onRestoreInstanceState(...);

还要记住，在onCreate（...）中，你的视图还没有恢复，它们只是在以后才恢复。

我有点晚了，但这可能是有用的任何人谁想要手动存储和恢复视图的可见性状态。

fun Bundle.saveVisibility(vararg views: View) {
    views.forEach { view ->
        putInt(view.id.toString(), view.visibility)
    }
}

fun Bundle.restoreVisibility(vararg views: View) {
    views.forEach { view ->
        if (containsKey(view.id.toString())) {
            view.visibility = getInt(view.id.toString())
        }
    }
}

片段中的用法

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
     savedInstanceState?.restoreVisibility(*viewDataBinding.inputViews.toTypedArray())
}

override fun onSaveInstanceState(outState: Bundle) {
    super.onSaveInstanceState(outState)
        outState.saveVisibility(*viewDataBinding.inputViews.toTypedArray())
    }

private val FragmentGroupCreateDepositsBinding.inputViews: List<View>
    get() = listOf(tilSharePrice, tilFlatAmount, tilMinAmount, tilMaxAmount, tvRequiredHint, llRangeAmount)
