Usage

From source file:Main.java

public static int applyNewLineCharacter(TextView textView) {
    Paint paint = textView.getPaint();
    String text = (String) textView.getText();
    int frameWidth = getPixelFromDp(textView, 120f);
    int startIndex = 0;
    int endIndex = paint.breakText(text, true, frameWidth, null);
    String save = text.substring(startIndex, endIndex);
    // Count line of TextView
    int lines = 1;

    while (true) {
        // Set new start index
        startIndex = endIndex;/*from   www  .  j av  a2s .com*/
        // Get substring the remaining of text
        text = text.substring(startIndex);

        if (text.length() == 0) {
            break;
        } else {
            lines++;
        }

        // Calculate end of index that fits
        endIndex = paint.breakText(text, true, frameWidth, null);
        // Append substring that fits into the frame
        save += "\n" + text.substring(0, endIndex);
    }
    // Set text to TextView
    textView.setText(save);
