B4A Library ProgressPieView

Attached project draws progress pie charts. Library files are in the /files folder of the attached project:

1. ProgressPieView.jar
2. ProgressPieView.xml

Copy both these files to your additional libraries folder. You will also need android-support-v4.jar to be present in your additional libraries folder. You can download it from here. The project makes use of files in the /Objects/res/values folder of the B4A project. Thus, use the attached B4A project as the base to work from.

All methods called by ppv1 to ppv4 (blocked and unblocked in the B4A project) are available for use. Very simple to use/figure out.

Sample code of methods as used in the attached project for ppv1 to ppv4 (CustomViews with CustomTypes set to ProgressPieVew):

    mbm.Initialize(File.DirAssets,"2.png")
    md.Initialize(mbm)

    ppv1.ImageDrawable = md      'load the drawable
    ppv1.ShowStroke = True       'show the outer circle
    ppv1.StrokeWidth = 10dip     'the width of the outer ring
    ppv1.StrokeColor = Colors.Red
    ppv1.ShowText = False

Really nice. Well done, @Johan Schoeman !

How would you add the ProgressPieView to another view in code? There is no "ProgressPieView.initialize".

John, ProgressPieView makes use of a custom type view and the custom view's custom type property needs to be set. I stand to be corrected but as far as I know this can only be done in the IDE. In other words add the customview ins the IDE, set its custometype property to ProgressPieVie and then you can set its position (left, top, width, height) in code.

 

[DonManfred]

. I stand to be corrected but as far as I know this can only be done in the IDE.

No

You need to add an INITIALIZE Method beside the already existent _INITIALIZE...
Additional you need to create a Method to manually add a view to the activity. You then can do all in code too without using the Designer too...

I´ll send you an example later.

 

[DonManfred]

Johan: Can you send me your project of this lib. I´ll edit it and send it back to you this evening. So you then can use the source for the future...

Will do. Thanks Manfred.

 

[thedesolatesoul]

Additional you need to create a Method to manually add a view to the activity.

If you are extending ViewWrapper you dont need to do this.
You should be able to use Activity.AddView(ProgressPieView,x,y,z)

 

[DonManfred]

Surely you are right, @thedesolatesoul
But the 2nd initialize method he need to add to the lib-

 

[thedesolatesoul]

Yes. There is a @BA.Hide infront of it that needs to be removed to expose it.

 

[DonManfred]

i usually do it like this

    public void Initialize(final BA ba, String EventName) {
        _initialize(ba, null, EventName);
    }
   
    @Hide
    public void _initialize(final BA ba, Object activityClass, String EventName) {
        this.eventName = EventName.toLowerCase(BA.cul);
        this.ba = ba;
        this.setObject(new ProgressPieView(ba.context));
   
     }

New project with library files (JAR & XML) in the /files folder. I have only amended the B4A code for ppv1. Other 3 are still via the Designer/IDE. You can change the rest of the B4A code as per ppv1. So you can now add it via code.

Thanks @DonManfred and @thedesolatesoul

        this.ba = ba;
        this.setObject(new ProgressPieView(ba.context));
  
     }

Yes, thats how I would do it too.

Johan, This version works perfectly for creating the view in code!!! Thank you very much for your efforts!
