Android: Get chars to fit in a textview width

int totalCharstoFit= textView.getPaint().breakText(fullString,  0, fullString.length(), 
 true, textView.getWidth(), null);

Now totalCharstoFit contains the exact characters that can be fit into one line. And now you can make a sub string of your full string and append it to the TextView like this,

String subString=fullString.substring(0,totalCharstoFit);
textView.append(substring);

And to calculate the remaining string, you can do this,

fullString=fullString.substring(subString.length(),fullString.length());

Now the full code,

Do this in a while loop,

while(fullstirng.length>0)
{
int totalCharstoFit= textView.getPaint().breakText(fullString,  0, fullString.length(), 
     true, textView.getWidth(), null);
 String subString=fullString.substring(0,totalCharstoFit);
    textView.append(substring);
 fullString=fullString.substring(subString.length(),fullString.length());

}
