    I don’t know if I wrote it correctly, but I need to check) Try hanging this logic on a button.

    editText.post(new Runnable() { @Override public void run() { int lineCount = editText.getLineCount(); String line; StringBuilder stringBuilder = new StringBuilder(); for (int i = 0; i < lineCount; i++) { int startPos = editText.getLayout().getLineStart(i); int endPos = editText.getLayout().getLineEnd(i); line = editText.getText().toString().substring(startPos, endPos); stringBuilder.append("*").append(line); stringBuilder.append("\n"); } editText.setText(stringBuilder.toString()); } });
    • Thanks for the response. But this is not a solution ( - researcher
