Answer 1

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 lineList = Arrays.asList(message.split("\n"));
            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 wordList = Arrays.asList(lineList.get(i).split(" "));
