Answer 1

In short, you get the bitmap rom the drawing cache:

v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());

There are several questions here with answers showing full code:

• Android take screenshot via code

• How to programmatically take a screenshot in Android?

These are methods of the View class, so they are applicable to any derived one (including ImageView)

Answer 2

You could hold a Bitmap Object in Background this piece of code:

Matrix matrix = new Matrix();
matrix.postScale(scaledWidth, scaledHeight);

Bitmap resizedBitmap = Bitmap.createBitmap(originalBitmap, 0, 0,
    originalBitmap.width(), originalBitmap.height(), matrix, true); 

And save it later using this code:

OutputStream fOut = null;
File file = new File(strDirectoy,imgname);
fOut = new FileOutputStream(file);

resizedBitmap.compress(Bitmap.CompressFormat.PNG, 0, fOut);
fOut.flush();
fOut.close();
