Android Question 3 Progressbar questions

[grafsoft]

Hi,

1. I have a pgrogressbar, not created with the designer.

I get a crash with "java.lang.NullPointerException: Attempt to write to field 'int anywheresoftware.b4a.BALayout$LayoutParams.left' on a null object reference"

Sub Globals
  
    Dim PB As ProgressBar
End Sub


Sub Activity_Create(FirstTime As Boolean)
    PB.initialize ("Progress")
    PB.Visible=False
    PB.SetLayout (10%x,45%y,80%x,10%y) ' crashes here
    PB.color=Main.a400color

2. I want to intercept the event when the progressbar has reached 100%, like "Sub Progress_Jobdone"

I know the trick with sub + blank + tab, but I don't get any help pn progressbar. When I try to use the designer (Generate members) - same result.

3. It must be my fault, but I do not find any documentation on this object.

1) You must add the ProgressBar onto the Activity or a Panel liky any other view added in the code !
Activity.AddView(PB, 10%x,45%y,80%x,10%y)
instead of
PB.SetLayout (10%x,45%y,80%x,10%y)

2) What do expect ?
There is nothing 'automatic' in this view it only shows a progress but it's up to you to change the progress value depending on the function you execute, so you should know when it's finished.

3) This is from the Help.
