Question

I have a scenario where i need to have a large number of progress bar drawables. I cant create xml resources for all of them because i want the user to choose a color that will

Answer 1

From the links provided by Rajesh and g00dy, i was able to come up with a solution.

public static Drawable createDrawable(Context context) {

ShapeDrawable shape = new ShapeDrawable();
shape.getPaint().setStyle(Style.FILL);
shape.getPaint().setColor(
    context.getResources().getColor(R.color.transparent));

shape.getPaint().setStyle(Style.STROKE);
shape.getPaint().setStrokeWidth(4);
shape.getPaint().setColor(
    context.getResources().getColor(R.color.category_green_stroke));

ShapeDrawable shapeD = new ShapeDrawable();
shapeD.getPaint().setStyle(Style.FILL);
shapeD.getPaint().setColor(
    context.getResources().getColor(R.color.category_green));
ClipDrawable clipDrawable = new ClipDrawable(shapeD, Gravity.LEFT,
    ClipDrawable.HORIZONTAL);

LayerDrawable layerDrawable = new LayerDrawable(new Drawable[] {
    clipDrawable, shape });
return layerDrawable;
}

This code will create a drawable that is visually similar to what the xml in my question creates.
