Android Code Snippet RotatingImage - a short sample

I like moving things on i.e. the InfoScreen of an App.

So, rotating existing images is a nice & simple way to reach that goal.
It isn't hard to solve, just some simple lines of Code.

1. Declare a variable for the timer and the rotating angle:

Code: Copy

Sub Class_globals
    Private Timer1 as Timer
    Private rotawinkel As Int
End Sub

2. set it to 0 (Zero) - or any othe angle you want

Code: Copy

Public Sub Initialize
    rotawinkel = 0
End Sub

3. include it in Timer1_Tick

Code: Copy

Private Sub Timer1_Tick
    rotawinkel = rotawinkel + 1
    YourImageView.As(B4XView).Rotation = rotawinkel
    If rotawinkel = 360 Then
        rotawinkel = 0
    End If
End sub

4. Initialize (start) the Timer1:

Code: Copy

Private Sub B4XPage_Created (Root1 As B4XView)
    Timer1.Initialize("Timer1",1000)
    ...
    ...
    ...
    Timer1_Tick
    Timer1.Enabled = True
End Sub

YOUR DONE !

Here is a sample Video of it:
YT: RotatingImageView

btw: this timer is linked to the clock, so only 1 tick per Second.
Of course you can create an additional timer and set it to.

Code: Copy

    Timer2.Initialize("Timer2",200)

to speed things up

Don't forget to create, initalize and start the 2nd timer
