How can I create an image placeholder of an image I am fetching from the web?

I am given the image size, and i want to create a placeholder of that image size's ratio. A simple solid gray color is fine.

You can create one in code like this:

Bitmap b = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(b);
Paint p = new Paint();
p.setColor(Color.GRAY);
p.setStyle(Paint.Style.FILL);
c.drawRect(0, 0, width, height, p);

but I think it's easier to just create an XML drawable:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FFCCCCCC"/>
</shape>

You can set that on the ImageView using its R.drawable ID, and then you don't have to worry about your memory use because Android is handling caching and all that.
