Text format and alignment should be like this:-
Table formatted data should be like this:-
I need some help Please.
Here i include my code which i try:-
String titleStr = "Title" + "\n\n";
StringBuilder contentSb = new StringBuilder();
contentSb.append("Item1 : 1221" + "\n");
contentSb.append("Item2 : test" + "\n");
StringBuilder content2Sb = new StringBuilder();
content2Sb.append("BANK : Us. 1.600" + "\n");
String message = "This is for test." + "\n\n";
long milis = System.currentTimeMillis();
String date = DateUtil.timeMilisToString(milis, "dd-MM-yy / HH:mm") + "\n\n\n\n";
byte[] titleByte = titleStr.getBytes();
byte[] content1Byte = contentSb.toString().getBytes();
byte[] messageByte = message.getBytes();
byte[] content2Byte = content2Sb.toString().getBytes();
byte[] dateByte = date.getBytes();
byte[] totalByte = new byte[titleByte.length + content1Byte.length + messageByte.length +
content2Byte.length + dateByte.length];
int offset = 0;
System.arraycopy(titleByte, 0, totalByte, offset, titleByte.length);
offset += titleByte.length;
System.arraycopy(content1Byte, 0, totalByte, offset, content1Byte.length);
offset += content1Byte.length;
System.arraycopy(messageByte, 0, totalByte, offset, messageByte.length);
offset += messageByte.length;
System.arraycopy(content2Byte, 0, totalByte, offset, content2Byte.length);
offset += content2Byte.length;
System.arraycopy(dateByte, 0, totalByte, offset, dateByte.length);
mmOutputStream.write(totalByte);
