Android Example Round Button - FunWithRoundButtons

Lib files are in the /files folder

This is my first attempt at making use of B4A classes. You will need
1. JavaObject library
2. Reflection library
3. AddPermission("android.permission.VIBRATE") to be added to the manifest - the attached project has this permission already added

It uses inline Java code to activate the vibrator when a button is pressed

The buttons all behave differently.

Button animations of the attached project now work properly. Over and above libs mentioned in post #2 above you will also need the StringUtils library.

Replace the code in Sub prepCircleButton10 with this:

Sub prepCircleButton10

    cb10.Initialize(b11, p11, 34%x, 70%y, 10%x, 10%x)
    cb10.setButtonGradientColor(Colors.Green, Colors.Green)
    cb10.setGradientDir = GradDir.RIGHT_LEFT
    cb10.RingColor = Colors.Green
    cb10.Initialize2(Me,"cb10_Click")
    cbm10.Initialize(File.DirAssets, "youtube48.png")
    cb10.setBitMap = cbm10
'    cb10.setButtonText = "CLICK ME!"
    cb10.setButtonReaction = Reaction.GROW_ALPHA_SHADOW_AND_SHRINK
    cb10.setRingSize = 10
    cb10.setButtonAnimationTime = 350
    cb10.setButton
   
End Sub

Replace the code of the last CASE in class circleButton with this:

      Case "GROW_ALPHA_SHADOW_AND_SHRINK"
        mpleft = mb.Left
        mptop = mb.Top
        mpwidth = mb.Width
        mpheight = mb.Height   
        mp.Color = Bit.AND(sclr(0),Colors.ARGB(80,255,255,255))
        mp.SetLayoutAnimated(animtime, mb.Left-rSize, mb.Top - rSize, mb.Width + (2 * rSize), mb.Height + (2 * rSize))
        Wait(animtime)
        mp.Invalidate
        mb.Invalidate
        mp.SetLayoutAnimated(animtime, mpleft, mptop, mpwidth, mpheight)
        mp.invalidate
        mb.Invalidate

This will then make the ring color around the (at present green) YouTube button a reduced alpha color of whatever color you specify with cb10.RingColor = Colors.COLOR
when the button is pressed/clicked.
