Android Question Field validation status

[ocalle]

Hi
Is there any way to validate an entry in an edittext or spinner?, that is to say when you leave the focus checks its validation and changes color or a tilde?
Useful I think when you have to fill many fields
Thanks in advance

I don't think there's anything built in. For EditTexts in one of my apps I have a utility function that I pass an array of EditTexts to & check if they are empty. It returns False if any of them is empty & True if they all aren't. If one of them is empty it draws a red border around it:

Public Sub checkFields(fields() As EditText) As Boolean
    Private xl As XmlLayoutBuilder
  
    For Each field As EditText In fields
        If field.Text = "" Then
            field.Background = xl.GetDrawable("edittexterror")
            Return False
        End If
    Next
    Return True
End Sub

'edittexterror.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <corners android:radius="0dp" />
    <stroke android:width="1dip" android:color="#FF0000" />
</shape>
