B4A Class [B4X] [XUI] AS Onboarding View V1.12

First, i spend a lot of time in creating views, some views i need by my self, but some views not and to create a high quality view cost a lot of time. If you want to support me, then you can do it here by Paypal. :)
If you want to show the new users the nicest features of your app, then i have the perfect view for you ;)

If you have wishes, bugs or a better design idea, then tell me it in the comments below.
Tested on B4A.

Thanks. It would be great if you add also a setting to keep the ratio of the add picture instead of stretch it to the size of the header. Sure that pic should be centred than.
The Header is not a image, you can put a image in the header, but the header is a B4xView it can also be a panel with parents. So you have the controll over the header, not the Class, the class is only resizing the Header if the width or height of the view is changed.

Please re-check V1.6: The B4J example is displaying only an empty small window

the DrawIndicators don't have the Height parameter in 2x calling lines.

As requested by the 'Private Sub DrawIndicators(Height As Float)'

the class is only resizing the Header
Ok, with a few modifications like:

  • giving back the AS ViewSizes:
B4X:
Public Sub getWidth As Int
   
    Return mBase.Width
   
End Sub
Public Sub getHeight As Int
   
    Return mBase.Height
   
End Sub

  • and changing the two lines in the GenImageViews-Sub:
B4X:
Private Sub GenImageViews(ImageName As String) As ImageView
   
    Private ImageView1 As ImageView
    ImageView1.Initialize("")
    ImageView1.SetLayoutAnimated(0,0,0, Activity.Width, Activity.Height*ASOnboarding1.Header_Size/100)
    ImageView1.Bitmap = xui.LoadBitmapResize(File.DirAssets,ImageName, ASOnboarding1.Width, ImageView1.Height, True)
    Return ImageView1
   
End Sub

The result is like I would like to have it. Thanks again.

change text color
Example:
B4X:
Dim tmp_btn as B4xview = asonboarding.getBackButton
tmp_btn.TextColor = xui.Color_Black

smooth swipe
No, because this is not based on a listview or tabstrip, but maybe i have the motivation in the next days, to make a 2.0 Version based on the xCustomListview, now i have some experience with that, like in my AS ColorChooser, this is based on the xCustomListview.

is it possible change indicator active / passive color by code
B4X:
IndicatorActiveColor
IndicatorInactiveColor

Could you calculate height of text because when i change font label can't show all text.
V1.11
  • Removed a unusded Variable
  • Add AutomaticCalculateDescriptionTextHeight Property, set it to true and the description text height adapts automatically to the text
But i dont have test it, i used the same code as in my B4X AutoTextSizeLabel
