Android EditText的问题'；关于文本更改侦听器

在我的Recyclerview的适配器类中，我做了如下工作：

holder.mEdtDescription.addTextChangedListener(object : TextWatcher {
    override fun afterTextChanged(p0: Editable?) {
    }

    override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
    }

    override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
        listener.onDeleteOrDescribe(position, "" + holder.mEdtDescription.text.toString(), "describe")
    }
})

holder.mIvDelete.setOnClickListener {
    listener.onDeleteOrDescribe(position, "", "delete")
}

mEdtDescription

是编辑文本

从回收器中删除某些值时，我的适配器调用方法

ondeleterdescripe

。 不幸的是，与此同时，ontextchange也在调用

删除soemthing时，如何避免调用

onTextChanged

希望你明白了

根据解决方案，我已尝试禁用textWatcher，如下所示：

val textWatcher: TextWatcher = object : TextWatcher {
        override fun afterTextChanged(p0: Editable?) {
        }

        override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
        }

        override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
            ToastUtil.displayShortDurationToast(mContext,"called")
            listener.onDeleteOrDescribe(
                position,
                "" + holder.mEdtDescription.text.toString(),
                "describe"
            )
        }
    }
    holder.mEdtDescription.addTextChangedListener(textWatcher)

    holder.mIvDelete.setOnClickListener {
        //listener.onDeleteStep(position)
        holder.mEdtDescription.removeTextChangedListener(textWatcher)
        listener.onDeleteOrDescribe(position, "", "delete")
        holder.mEdtDescription.addTextChangedListener(textWatcher)
    }

但是，仍在调用onTextChange（）：（

您可以尝试暂时禁用TextWatcher：

val textWatcher :  TextWatcher = object : TextWatcher {
    override fun afterTextChanged(p0: Editable?) {
    }

    override fun beforeTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
    }

    override fun onTextChanged(p0: CharSequence?, p1: Int, p2: Int, p3: Int) {
        listener.onDeleteOrDescribe(position, holder.mEdtDescription.text.toString(), "describe")
    }
}

holder.mEdtDescription.addTextChangedListener(textWatcher)

holder.mIvDelete.setOnClickListener {
    holder.mEdtDescription.removeTextChangedListener(textWatcher)
    listener.onDeleteOrDescribe(position, "", "delete")
    holder.mEdtDescription.addTextChangedListener(textWatcher)
}

但是，当我更改EditText内容时应该调用它，在这种情况下，当我更改描述时，它将不起作用。它也不起作用。我已在内部禁用并启用了它。当触发mIvDelete onClickListener时，onTextChanged（）将方法被调用？即使TextChangedListener之前已被删除？是的，先生，我已通过在内部制作toast进行了检查。
