Answer 1

  Bitmap bitmap;
  View v1 = findViewById(R.id.rlid);// get ur root view id
  v1.setDrawingCacheEnabled(true); 
  bitmap = Bitmap.createBitmap(v1.getDrawingCache());
  v1.setDrawingCacheEnabled(false);

This should do the trick.

For saving

  ByteArrayOutputStream bytes = new ByteArrayOutputStream();
  bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
  File f = new File(Environment.getExternalStorageDirectory()
                    + File.separator + "test.jpg")
  f.createNewFile();
  FileOutputStream fo = new FileOutputStream(f);
  fo.write(bytes.toByteArray()); 
  fo.close();
