Question

For my app I have created a QR Code, then took that bitmap and added text to the bitmap, however I need the text not to extend longer then the bitmap is. So what I want to do is create an Array of the text by taking 25 characters then find the last index of (” “) in that 25 character section. at that space I want to be able to replace that space that was located with \n to start a new line.

So the plan is if I have a String that looks like “Hello this is my name and I am longer than 25 charters and I have lots of spaces so that this example will work well.“

I want it to out up this

Hello this is my name and
I am longer than 25 
charters and I have lots 
of spaces so that this 
example will work well.

To make this I counted 25 characters then went back to the most resent space, at that point I hit enter, I want my app to do this for me.

I am not very good at English so if something doesn’t make sense tell me and I will try to explain it. Thanks

I haven’t tested this but you can try it and tweak as necessary

String fullText = "your text here";
String withBreaks = "";
while( fullText.length() > 25 ){
    String line  = fullText.substring(0,24);
    int breakPoint = line.lastIndexOf( " ");
    withBreaks += fullText.substring(0,breakPoint ) + "\n";
    fullText = fullText.substring( breakPoint );
withBreaks += fullText;
