我的申请流程:
stockerFragment:
使用条形码扫描仪输入条形码
如果之前已经扫描过条形码,则滚动平滑到现有条形码并显示对话框模式以编辑数量。
用户在对话框模式中编辑数量后按Enter键,关闭对话框并滚动平滑到最后位置。 < - 此步骤中发生错误。它只是关闭对话框而不是自动滚动到最后一个位置。
这是Qty edittext上的代码:
class ModalQtyOnKeyListener(
private val dialog: Dialog,
private val QtyTextToEdit: EditText,
private val QtyModal: EditText,
private var oldQty: Any,
private val currentBarcodeText: EditText,
val recyclerView: RecyclerView,
private val mContacts: MutableList<BarcodeList>) : View.OnKeyListener {
init{
oldQty = try {
oldQty.toString().toInt()
} catch (e: NumberFormatException) {
1
}
}
override fun onKey(v: View, keyCode: Int, event: KeyEvent): Boolean {
if (event.action == KeyEvent.ACTION_UP) {
return if (keyCode == 66) {
var newQty = 0
var barcode = ""
if(QtyModal.text.length >= 12)
{
val pattern = Pattern.compile("([0-9]+)?([a-zA-Z]{3}[0-9]+)")
val matcher = pattern.matcher(QtyModal.text.toString())
if (matcher.find()) {
val qty = if (matcher.group(1)!= null) matcher.group(1) else QtyModal.text.toString()
barcode = if (matcher.group(2)!= null) matcher.group(2) else ""
newQty = QtyTextToEdit.text.toString().toInt() + qty.toString().toInt()
}
} else
{
newQty = QtyModal.text.toString().toInt() + QtyTextToEdit.text.toString().toInt()
barcode = QtyModal.text.toString()
}
QtyTextToEdit.setText(newQty.toString())
// from this line where the code is not working
recyclerView.postDelayed({
// Call smooth scroll
// FYI: I already debug mContacts.size return correct position
recyclerView.layoutManager.scrollToPosition(mContacts.size)
}, 100)
// FYI: current barcode and recyclerview not in modal dialog but in the fragment.
currentBarcodeText.postDelayed({
currentBarcodeText.requestFocus()
currentBarcodeText.setText("")
if(barcode.length==12)
{
currentBarcodeText.setText(barcode)
currentBarcodeText.setSelection(barcode.length)
currentBarcodeText.dispatchKeyEvent(KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER))
currentBarcodeText.dispatchKeyEvent(KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_ENTER))
}
}, 130)
// until this line where the code is not working
dialog.hide()
dialog.dismiss()
true
} else false
}
return false
}
}
答案 0 :(得分:0)
首先,请允许我说这个答案基于您的问题中的不充分信息(甚至不是形成一个问题 - 请参阅How to ask a good question)。
您使用延迟帖子来更新回收站,并使用延迟帖子来更新视图。如果视图(currentbarcode
)由延迟发布到您的回收站设置或更新,则延迟发布到当前视图的结果将是未定义的。但是,根据你原来的问题,我们无法判断。
您的第一步应该是将延迟的帖子移除到currentbarcode
并自动滚动工作。
当它工作时,您应该移动您的呼叫以将currentbarcode
更新为传递给回收者延迟帖子的lambda。
