我需要在Jetpack Compose中为TextField实现redo/undo。对于EditText，我使用了这个one，它运行得很好。但是，对于Jetpack Compose，没有这样的侦听器。我将基于EditText的侦听器实现一个自己的侦听器，但是我缺少这两个侦听器方法，它们对TextField不可用：

doOnTextChanged { text, start, before, count -> }
doBeforeTextChanged { text, start, count, after -> }

在TextField中只能使用一个侦听器

onValuesChange = { }

仅返回没有start和count****字符串**
我找了找，什么也没找到。
如何在Jetpack Compose中为TextField实现重做/撤消？

• 谢谢-谢谢

  顺便说一句，这就是我到目前为止所做的。如果能让它发挥作用就太好了。

class EditTextDo {

    private var mIsUndoOrRedo = false
    private val editHistory: EditHistory? = null

    fun redo() {
        val edit = editHistory?.getNext() ?: return

        // Do Redo
    }

    fun undo() {
        val edit = editHistory?.getPrevious() ?: return

        // Do Undo
    }

    fun canUndo(): Boolean {
        editHistory?.let {
            return it.position > 0
        }
        return false
    }

    fun canRedo(): Boolean {
        editHistory?.let {
            return it.position < it.history.size
        }
        return false
    }

}

class EditHistory {

    var position = 0

    private var maxHistorySize = -1

    val history = LinkedList<EditItem>()

    private fun clear() {
        position = 0
        history.clear()
    }

    fun add(item: EditItem) {
        while (history.size > position) {
            history.removeLast()
        }
        history.add(item)
        position++
        if (maxHistorySize >= 0)
            trimHistory()
    }

    fun getNext(): EditItem? {
        if (position >= history.size) {
            return null
        }
        val item = history[position]
        position++
        return item
    }

    fun getPrevious(): EditItem? {
        if (position == 0) {
            return null
        }
        position--
        return history[position]
    }

    private fun setMaxHistorySize(maxHistorySize: Int) {
        this.maxHistorySize = maxHistorySize
        if (maxHistorySize >= 0)
            trimHistory()
    }

    private fun trimHistory() {
        while (history.size > maxHistorySize) {
            history.removeFirst()
            position--
        }
        if (position < 0)
            position = 0
    }
}

data class EditItem(val start: Int, val before: CharSequence, val after: CharSequence)
