After too much searching and waiting for an answer to this question. I have resolved this issue.
Solution:
I have measured each and every line & words for preserve this as Multiline text, you can use below function for that.
DisplayMetrics metrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(metrics);
float density = metrics.density;
String result = fitString(ipText, ipText.getText().toString());
private String fitString(EditText editText, String message) {
Log.i(TAG, "fitString: Default String : " + message);
StringBuilder finalMessage = new StringBuilder();
if (isTooLarge(editText, message)) {
Log.i(TAG, "fitString: isTooLarge 1 : " + true);
List<String> lineList = Arrays.asList(message.split("
"));
Log.i(TAG, "fitString: stringList" + lineList);
if (lineList != null && lineList.size() > 0) {
for (int i = 0; i < lineList.size(); i++) {
if (lineList.get(i) != null && !lineList.get(i).isEmpty()) {
if (isTooLarge(editText, lineList.get(i))) {
Log.i(TAG, "fitString: isTooLarge 2 : " + lineList.get(i) + " == " + true);
List<String> wordList = Arrays.asList(lineList.get(i).split(" "));
Log.i(TAG, "fitString: wordList" + wordList);
if (wordList != null && wordList.size() > 0) {
Log.i(TAG, "fitString: wordList : " + wordList.size());
StringBuilder temp = new StringBuilder();
String lastWord = "";
for (int j = 0; j < wordList.size(); j++) {
if (wordList.get(j) != null && !wordList.get(j).isEmpty()) {
