android - How to pass AttributeSet as a parameter -

i'm trying implement updated solution pedram this answer, don't know create new instance of circleprogressbar. requires attributeset passed parameter, how it?

circleprogressbar circleprogressbar = new circleprogressbar(mainactivity.this, ?); 

the attributeset constructor used when view inflated through layout defined in xml. if you're constructing 1 in code, should use single argument constructor (e.g. new circleprogressbar(mainactivity.this)). if single-argument constructor not defined, need add it. you'll need add getters/setters properties if want able construct entirely within java code.

alternately, define layout xml (example name view_progress_circle.xml) single item:

<com.your.packagename.circleprogressbar     android:layout_width="100dp"     android:layout_height="100dp"     // etc. add other attributes here     /> 

then in code, create with:

circleprogressbar bar = (circleprogressbar) layoutinflater.from(mainactivity.this)         .inflate(r.layout.view_progress_circle, parent, false): 

where parent viewgroup you're going attach view to.
