Can we now copy the icons into a bitmap?

no. If the original lib will be updated i can do an update for the wrap.

How to use in label and button ?

 

[DonManfred]

Use the generated drawable and set it to the label/button is the only you can try

 

[corwin42]

I just tried this library.

The MaterialDrawableBuilder is useless in the current implementation. The main method to set the Icon is missing. Would be even nice if the setAlpha() method will get wrapped.

Btw. the library was updated with many more new icons...

 

[DonManfred]

I´ll check the newest release and update the wrapper

 

[DonManfred]

The main method to set the Icon is missing.

What do you mean exactly? It IS there. And it was there in the "old" implementation. But you cant set the icon with it´s name... You only can set the index of the icon you want to use. See example-code. That´s the way the github project exüect the icon to set.

If you know a easy way to change the enum used by the github project so be a setter with the name of the icon; show me how and i´ll do if not much work.

I´ve updated the lib to use the newest github release. Now 1712 Icons.

The #additionalres is no longer needed. Also not the fontfile in the assets (it is now inside the aar).

Excellent Contribution!

I'm talking about the MaterialDrawableBuilder, not the MaterialIconView. The MaterialDrawableBuilder doesn't have the Icon property. You cannot set an Icon so the object is useless. I tried to use it but get the error that no icon was choosen.

[jayel]

hello,

How can I set the logodrawable with an icon from materialicons?

    Dim mi As MaterialIconView
    mi.Initialize("MaterialIcon")
    mi.Icon = 153
    mi.Color = 0xFF045B32
    ActionBar1.LogoDrawable = mi  <---- ERROR

 

[prajinpraveen]

is it possible to get a drawable object that can be used on a button? thanks

My large project will not work with Materialcon 2.0 using B4A 8.80 and 9.00. Material Icon 1.5 works ok with B4A 8.80 but B4A 9.00 will not work. MaterialIcon 1.5 and 2.0 will not work with B4A 9.00
