Programmatically create ShapeDrawable

Question

I'm trying to programmatically create a ShapeDrawable but the following code doesn't show anything.

ImageView image = new ImageView (context);
image.setLayoutParams (new LayoutParams (200, 200));
ShapeDrawable badge = new ShapeDrawable (new OvalShape());
badge.setBounds (0, 0, 200, 200);
badge.getPaint().setColor(Color.RED);
ImageView image = new ImageView (context);
image.setImageDrawable (badge);
addView (image);

I can get it working with xml.

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <size
        android:width="200px"
        android:height="200px" />
    <solid
        android:color="#F00" />
</shape>

ImageView image = new ImageView (context);
image.setLayoutParams (new LayoutParams (200, 200));
image.setImageResource (R.drawable.badge);
addView (image);

But I would like to create it programmatically. The xml works perfectly so the problem can't be with the ImageView, it must be in creating the ShapeDrawable.

Did you try setting layout bounds to your imageview? PLease add the information about the layout where you add the imageview to — David Medenjak, Jan 06 '16 at 20:43
What is the point of this? ImageView image = new ImageView (context); for the second time? — The_Martian, Jan 07 '16 at 01:29

Use setIntrinsicWidth and setIntrinsicHeight instead of setBounds to set the width and height.

ImageView image = new ImageView (context);
image.setLayoutParams (new LayoutParams (200, 200));
ShapeDrawable badge = new ShapeDrawable (new OvalShape());
badge.setIntrinsicWidth (200);
badge.setIntrinsicHeight (200);
badge.getPaint().setColor(Color.RED);
image.setImageDrawable (badge);
addView (image);

You might need to create a Class extending ShapeDrawable to override onDraw and then create an instance of your class.

Example: (Source - check link for full example)

private static class MyShapeDrawable extends ShapeDrawable {
            private Paint mStrokePaint = new Paint(Paint.ANTI_ALIAS_FLAG);

            public MyShapeDrawable(Shape s) {
                super(s);
                mStrokePaint.setStyle(Paint.Style.STROKE);
            }

            public Paint getStrokePaint() {
                return mStrokePaint;
            }

            @Override protected void onDraw(Shape s, Canvas c, Paint p) {
                s.draw(c, p);
                s.draw(c, mStrokePaint);
            }
        }
