I have a spannnable string and that spannable sting containg images and string and but When i Display that string on textview that images align with base line of textview i want to display ALIGN_TOP with that string I am stuck on this please help me to sort out.
Here is my code
String text2 = " Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. ";
Spannable spannable = new SpannableString(text2);
spannable.setSpan(new ImageSpan(mActivity, R.mipmap.start_quote_green), 0, 1, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
spannable.setSpan(new ImageSpan(mActivity, R.mipmap.end_quote_green), text2.length()-1, text2.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE);
inspirationalActivityInspirationalTextTv.setText(spannable, TextView.BufferType.SPANNABLE);
Here is Answer
