Just modify the code to

String pattern = "";
for (int j = 0; j < getText().toString().length(); j++) {
    pattern += "*"; //Any Character that you want to display 
}
for (int i = 0; i < mNumChars; i++) {
    canvas.drawLine(startX, bottom, startX + mCharSize, bottom, mLinesPaint);
    if (getText().length() > i) {
         float middle = startX + mCharSize / 2;
         canvas.drawText(pattern, i, i + 1, middle - textWidths[0] / 2, bottom - mLineSpacing, getPaint());
    }
    if (mSpace < 0) {
        startX += mCharSize * 2;
    } else {
        startX += mCharSize + mSpace;
    }
}
