Android Question Object should first be initialized (EditText).

[Nickle]

Hi There,

I keep getting this Error. I know I have not done something right but cant figure it out. My Intention is to get the field values from EditText and based on values purpose validation. I am using XmlLayoutBuilder for the first time.

java.lang.RuntimeException: Object should first be initialized (EditText).

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.
    Dim ButtonLogin As Button
    Dim btnLinkToRegisterScreen As Button
    Dim vdsLogo As ImageView
    Dim vMobile As EditText
    Dim vPassword As EditText
    Dim First As String
    Dim Second As String

End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Dim x As XmlLayoutBuilder
    x.LoadXmlLayout(Activity, "activity_login")
    Dim tc As Int = 0xffffffff 'the format is AARRGGBB
    Activity.Color = tc
    vdsLogo = x.GetView("vdsLogo")
    ButtonLogin = x.GetView("button1")
    vMobile.Initialize("")
    vMobile = x.GetView("txtmobile")
    vPassword = x.GetView("txtpassword")
End Sub

Sub ButtonLogin_Click
    First = vMobile.Text
    Msgbox(vMobile.Text, "")
End Sub

Why use XmlLayoutBuilder? B4A is designed to work with the internal designer.

I already have a project in Android Studio and need to import my xml layouts to B4A..

You have vmobile.initialize, but not vpassword.initialize?

I get same error even If I initial both EditText fields

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Dim x As XmlLayoutBuilder
    x.LoadXmlLayout(Activity, "activity_login")
    Dim tc As Int = 0xffffffff 'the format is AARRGGBB
    Activity.Color = tc
    vdsLogo = x.GetView("vdsLogo")
    ButtonLogin = x.GetView("button1")
    vMobile.Initialize("")
    vMobile = x.GetView("txtmobile")
    vPassword.Initialize("")
    vPassword = x.GetView("txtpassword")
End Sub

Sub ButtonLogin_Click
    First = vMobile.Text
    Msgbox(vMobile.Text, "")
    'StartActivity("Test")
End Sub

You shouldn't initialize those views.

Can you post the XML?

It should be mobile and password instead of txtMobile and txtPassword.
