解决RecycleView 中Item包含Edittext时，滑动view复用导致数据错乱的问题

解决RecycleView 中Item包含Edittext时，滑动导致数据错乱的问题

一言不合就上代码：

override fun onBindViewHolder(p0: InnerHolder, position: Int) {
        var item :AppOnShelfDetail = mStringSparseArray[position]
        p0.tv_content_code.text = item.itemCode //商品编码
        p0.tv_ready_up_number.text = StringUtil.intToString(item.reqQty)
        if (p0.editText.tag is TextWatcher) {
            p0.editText.removeTextChangedListener(p0.editText.tag as TextWatcher?)
        }

        if (p0.editTextCode.tag is TextWatcher) {
            p0.editTextCode.removeTextChangedListener(p0.editTextCode.tag as TextWatcher?)
        }

        val editWatcher = EditWatcher(position, item,p0)
        val editWatcherCode = EditWatcherCode(position,item, p0)

        p0.editText.addTextChangedListener(editWatcher)
        p0.editTextCode.addTextChangedListener(editWatcherCode)

        p0.editText.tag = editWatcher
        p0.editTextCode.tag = editWatcher
        if (mStringSparseArray[position].onshelfQty == 0)  p0.editText.setText("")
        else p0.editText.setText(StringUtil.intToString(mStringSparseArray[position].onshelfQty))//实际上架数量
        p0.editTextCode.setText(mStringSparseArray[position].locationCode)//上架库位

    }

    inner class EditWatcher(val position: Int,var item :AppOnShelfDetail, val hoilder: GoodsUpDetailAdapter.InnerHolder) : TextWatcher {

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

        override fun afterTextChanged(content: Editable?) {

            if (!content.isNullOrEmpty()) {
                val readyUpCount: Int =  hoilder.tv_ready_up_number.text.toString().toInt()
                    val signCount: Int = content.toString().toInt()//实上架数量
                    if (signCount <= readyUpCount) {
                        item.onshelfQty = signCount
                    }else{
                        ToastUtils.show("实上架数量大于待上架数量,请重新输入")
                    }

                mStringSparseArray.put(position, item)
            }

        }


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

        }

    }


 inner class EditWatcherCode(val position: Int,var item :AppOnShelfDetail, val hoilder: GoodsUpDetailAdapter.InnerHolder) : TextWatcher {

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

        override fun afterTextChanged(content: Editable?) {

            if (!content.isNullOrEmpty()) {
                var locationCode: String = content.toString()//唯一码
                item.locationCode = locationCode
                mStringSparseArray.put(position, item)
            }
//            else {
//                mStringSparseArray.delete(position)
//            }
        }


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

        }

    }

核心代码就这么多，接下来再加上 局部刷新，就可以解决滑动复用导致的数据错乱问题

   fun setData(stringSparseArray: SparseArray<Object>, count: Int,index:Int) {
        mStringSparseArray = stringSparseArray
        mCount = count
//        notifyDataSetChanged()
        notifyItemChanged(index)
    }
