Android Question array list question

I don't know that lib, but if Chart_High_Data is presenting a list you could try:

B4X:

mlc1.Chart_High_Data.addAll(listhigh)

What type is it expecting?

Is it a float array?

You could try:

B4X:

    Dim LJO As JavaObject = listhigh
    mlc1.Chart_High_Data = LJO.RunMethod("toArray",Null)

If that doesn't work I'll download the library

OK you need to convert the list to a Float Array, it can be done with JavaObject:

B4X:

Dim LJO As JavaObject = listhigh
    Dim AJO As JavaObject
    AJO.InitializeArray("java.lang.Float",LJO.RunMethod("toArray",Null))
    mlc1.Chart_High_Data = AJO

Should work, but there is probably no benefit over doing it directly

B4X:

Dim Farray(listhigh.size) As Float
For i = 0 to listhigh.size - 1
  Farray(i) = listhigh.get(i)
Next
mlc1.Chart_High_Data = Farray
