You may use only 1 buildDrawingCache(), the subsequent ones will replace the previous contents.
So, you better group the EditText and the ImageView into a container and shoot that one.

OR...

Instead of using an EditText, just use a TextView.
This one can have one or more compound drawable inside.

So, you may shoot the TextView only.

This is a preferred solution, since it reduces the View and (possibly) the layout count.

[EDIT]

To use compound drawables simply use in xml the android:drawableLeft = "@drawable/your_drawable" (and/or drawableRight, drawableTop, drawableBottom) attribute/s of your TextView.
To set them in Java, use setCompoundDrawablesWithIntrinsicBounds(int left, int top, int right, int bottom), as found in the official docs: http://developer.android.com/reference/android/widget/TextView.html#setCompoundDrawablesWithIntrinsicBounds(int, int, int, int)

Reminder:

If you are capturing the result image+text from screen, the quality of the output image is certainly compromised

If you want to keep the original quality of image, you should use Canvas and Bitmap to help you

Canvas c=new Canvas();
c.setBitmap(bitmap);   // *mutable* copy of bitmap of the image for the ImageView
c.drawText(text,  x,  y,  paint);  // font size and typeface can be set through "Paint" class

bitmap.compress(CompressFormat.PNG, 100, new FileOutputStream(out)); // export output

I don't understand why you need that but as I understand you should create new Bitmap object from drawing cache before set as source of ImageView

You need get drawing cache of Parent of that imageview & EditText.

parentLayout.buildDrawingCache();
Bitmap bitmap1 = parentLayout.getDrawingCache();

Where parentLayout contains imageview & EditText.
