Your TextView should support multines and when writting text into it use \n for a new line. — David Kasabji, Apr 06 '17 at 07:27
set the android:maxLines = 2 and adjust the size of your textview — Ezio, Apr 06 '17 at 07:27
you can use \n after completing your 23 characters in textview , so it will automatically start from the new line. — Rajshree Tiwari, Apr 06 '17 at 07:30

@user7144720

get EditText text inside one String variable

String finalString = "";
String textToShow = sampleEditText.getText().toString();
if (textToShow.length > 23) {
    finalString = textToShow.substring(0,23) + "\n" + textToShow.substring(23);
}
else {
    finalString = textToShow;
}
//then set finalString for your textview

textViewDisplay.setText(finalString);

Try this:

String your_data="abcdef......";
String value=setText(your_data);
textView.setText(value);

setText method:

public String setText(String text){

    String lineString = "";
    while (text.length() > 23) {

        String buffer = text.substring(0, 23);
        lineString = lineString + buffer + "/n";
        text = text.substring(23);
    }

    lineString = lineString + text.substring(0);
    return lineString;
}
