Android Question FloatLabeledEditText Editing Label

[kozbot]

So, I have 2 activities one has Labels 3 - 8, and the second is a carbon copy of the first but with the Float Labeled Edit Text 3 - 8. I want to be able to save any edit text labels on activity 2 using a save button so that the activity 1 shows the edited labels.

Any idea how I do this? I'm not really confident with what I've come up with:

Sub FloatLabeledEditText1_TextChanged (Old As String, New As String)
   Activity1.Label3 = FloatLabeledEditText1
End Sub

I'm guessing there's something more to it? TIA

Maybe you can store the texts in a service like "starter" in a field. So you can have a copy of the text in labels to get when the activity starts or resumes.
I don't know if this is what you are looking for...

You cannot access UI elements of a different activity.

You can use CallSubDelayed2 to start the second (or first) activity and pass the required information.

Would you suggest another way of doing this? Preferably quick?

 

[Erel]

CallSubDelayed(Activity2, "ShowData", CreateMap("value1": lblValue1.Text, "value2": lblValue2.Text, ...))

Public ShowData(values As Map)
 floatField.Text = values.Get("value1")

 

[Erel]

It should be CallSubDelayed2.

Hi Erel, I appreciate all your help on this, but as usual, I'm struggling. I am probably wrong in what I have done with your code that you sent me. I feel like I've missed something in the Activity 2 Show Data sub?

I keep getting an error: java.lang.Exception: Sub button2_click signature does not match expected signature.

Activity 1: (Zone)

Sub Button2_Click
    'This call will bring Activity2 to front and will then execute ShowList
    CallSubDelayed2(EditZones, "ShowData", CreateMap("value3": Label3.Text, "value4": Label4.Text, "value5": Label5.Text, "value6": Label6.Text, "value7": Label7.Text, "value8": Label8.Text))
End Sub

Sub GetResult(values As Map)
    Label3.Text = values.Get("value1")
End Sub

Activity 2: (EditZones)

Sub ShowData(values As Map)
    FloatLabeledEditText1.Text = values.Get("value3")
    FloatLabeledEditText2.Text = values.Get("value4")
    FloatLabeledEditText3.Text = values.Get("value5")
    FloatLabeledEditText4.Text = values.Get("value6")
    FloatLabeledEditText5.Text = values.Get("value7")
    FloatLabeledEditText6.Text = values.Get("value8")

End Sub

Sub Button2_Click (Position As Int, Value As Object)
    CallSubDelayed2(Zone, "GetResult", Value)
End Sub

 

[Erel]

The sub signature (in Activity 2) should be:

Sub Button2_Click

Sorry I'm getting the error:
java.lang.Exception: Sub button2_click signature does not match expected signature.

The code you posted in post #7 is incorrect as the signature of the button click event is wrong. If you fix it and you are still getting this error then you should post the updated code. Preferably upload the project (File - Export as zip).
