Android Question Seekbar

[Arturs]

Hi

How to change Seekbar value from service module (refresh value of seekbar) ?

Use CallSub or CallSubDelayed to call a sub in the Activity that will change the value.

I thought that I should use it.

CallSubDelayed needs the following parameters:Component as Object, Sub As String

My Sub is
Sub Seek_ValueChanged (Value As Int, UserChanged As Boolean)

How to pass parameters: Value and UserChanged ?

something I do not understand

Create a sub in your Activity. for example in MAIN

sub SetSeekbarValue(value As int)
  myseekbarname.value = value
end sub

And then from your Service

CallSubDelayed2(Main,"SetSeekbarValue",Array as int(16))

 

[Arturs]

I have the error : "java.lang.IllegalArgumentException: argument 1 should have type int, got int[]"

in the line myseekbarname.value = value

 

[DonManfred]

try not using an array

CallSubDelayed2(Main,"SetSeekbarValue",16)

 

[Arturs]

It works and simple to use

I thought that I cannot pass int value because CallSubDelayed2 expects Object type.

Could you explain me why we can use Int ?


CallSubDelayed2 (Component As Object, Sub As String, Argument As Object)

int, long, String, double... ALL of them are Objects

As @DonManfred wrote primitive types can be treated as objects (it is called auto-boxing).
