If you have created multiple images dynamically than try this one:

// initialize your images array

private ImageView myImages[] = new ImageView[your_array_length];

// create programatically and add to parent view

 for (int i = 0; i < your_array_length; i++) {
                myImages[i] = new ImageView(this);
                myImages[i].setId(i + 1);
                myImages[i].setBackgroundResource(your_array[i]);
                RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
                        frontWidth[i], frontHeight[i]);
                ((MarginLayoutParams) params).setMargins(frontX_axis[i],
                        frontY_axis[i], 0, 0);
                myImages[i].setAdjustViewBounds(true);
                myImages[i].setLayoutParams(params);

                if (getIntent() != null && i != your_array,length) {
                    final int j = i;
                    myImages[j].getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener() {
                        public boolean onPreDraw() {
                            myImages[j].getViewTreeObserver().removeOnPreDrawListener(this);
                    finalHeight = myImages[j].getMeasuredHeight();
                        finalWidth = myImages[j].getMeasuredWidth();
                    your_textview.setText("Height: " + finalHeight + " Width: " + finalWidth);
                            return true;
                        }
                    });
                }
                your_parent_layout.addView(myImages[i], params);
            }

// That's it. Happy Coding.
