我有两个字段和按钮的表格。当用户单击按钮时，我将隐藏所有视图的Errors（如果有的话），我将再次开始验证。以下是我的 Sub B_PDFs()
Dim PDFarray As String, PDFName as String, sht As String
Sheets("Control").Select
PLFile = ActiveWorkbook.Name
PDFLoc = Application.ActiveWorkbook.Path & "\"
PDFName = Range("A20")
PDFSheetCount = Range("J1").Offset(Rows.Count - 1, 0).End(xlUp).Row
'Loop through column J and create a string with each tab name to be exported
For x = 2 To PDFSheetCount Step 1
If x = PDFSheetCount Then
sht = """ " & "" & Cells(x, 10) & """ "
Else
sht = """" & "" & Cells(x, 10) & """" & ", "
End If
PDFarray = PDFarray & sht
Next x
'Create PDF from the array above
Worksheets(Array(PDFarray)).Select - this is where I get the error Subscript Out Of Range
Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:=PFDLoc & PDFName, Quality:= _
xlQualityStandard, IncludeDocProperties:=True, IgnorePrintAreas:=False,
OpenAfterPublish:=False
Workbooks(PLFile).Activate
End Sub
按钮点击代码
viewmodel _resetErrors.value = true
if (_bankAccount.value?.accountNumber.isNullOrBlank()) {
accountNumberError.value = "Please enter account number"
fieldLevelError.value = accountNumberError.value
return false
}
if (TextUtils.isEmpty(_bankAccount.value?.routNumber?.trim())) {
routingNumberError.value = "Please enter rout number"
fieldLevelError.value = routNumberError.value
return false
}
代码如下
XML android:id="@+id/layout_add_manual_account_account_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/dimen_16dp"
android:imeOptions="actionNext"
android:inputType="number|textNoSuggestions"
android:maxLines="1"
android:text="@={bankAccountViewModel.bankAccount.accountNumber}"
android:textAllCaps="true"
app:errorText="@{bankAccountViewModel.accountNumberError}"
app:resetError="@{bankAccountViewModel._resetErrors}" />
<com.transfast.transfast.v4.customviews.TFTextControlView
android:id="@+id/layout_add_manual_account_routing_number"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/dimen_16dp"
android:imeOptions="actionNext"
android:inputType="number|textNoSuggestions"
android:maxLines="1"
android:text="@={bankAccountViewModel.bankAccount.routingNumber}"
android:textAllCaps="true"
app:errorText="@{bankAccountViewModel.routNumberError}"
app:resetError="@{bankAccountViewModel._resetErrors}" />
代码如下
Binding Adapter由于我想隐藏所有字段的错误，因此我在两个字段之间共享@BindingAdapter("errorText")
fun setError(tfTextControlView: TFTextControlView, errorText: String) {
if(!errorText.isNullOrBlank()) {
tfTextControlView.error = errorText
}
}
@BindingAdapter("resetError")
fun resetError(tfTextControlView: TFTextControlView, isReset: Boolean) {
if (isReset) {
tfTextControlView.hideError()
}
。但是在绑定适配器中，_resetErrors在setError之前被调用，并且错误在错误场景中从未显示。如果有多个字段，重置错误的最佳方法是什么？（我有2个，但如果有20个，创建20个错误变量是不可行的。）还是如何使用实时数据重置多个字段的错误？
