Question

I want to thumbnail initials with two word for my image view like \"Peter Parker\" but am able to get only one word \"P\"while running code how can get second word after spa

Answer 1

it look's like your using substring to only grab the letters from position 0 to position 1, This is P in Petter

holder.imgName?.text=teamData[position].userImage  

.substring(0,1)

If you'd like to grab the words Petter Parker, you have a few options.
• IndexOf & Substring - find the position of a string and get the subtext after.
• Substring - Subtext of string based on parameters

If you plan to change the text length at any stage, you'll need to find the start of the word ( int start = yourString.indexOf("Petter"));
and end of the word ( int end = yourString.indexOf(" "))

IndexOf will return the position of the first letter in your query - Your case it's P in Petter --- So start+"petter".length()

Here's an example of a barcode price checker app I'm working on

                    // STRING  FORMAT 00000899999:0.99   

                    String currentLine = "00000899999:0.99";
                    int breakPoint = currentLine.indexOf(":");
                    int end = currentLine.length();
                    int start = breakPoint + 1;
                    String Price = currentLine.substring(start,end);

Price will be starting after (:) With +1 or include (:) with no + 1 and end at the lines length.
