Nice tutorial to get started…!
naveen March 29, 2013 at 4:52 pm
Hello Sir , these are very good tutorials and are in understandable way..thank u very much for that.
I have a query to ask you. I donot know its a small task or big task .but Suppose i have 20 lines of a text. In that when i click on some word it should popup an alert..
For instance lets take some text
“When I had a financial setback in the early 1990s, I saw it
more as an “ABBERATION ” from the norm than as a final sentence. I
knew what it was like to be whole, and all I had to do was get
back to that place.”
In the text when i click or touched the word ABBERATION (quoted and capitalized ) in above text it should give me a pop-up with my own text ( i’ll write while coding)
I know one way is writing the text in set message method (alert.setMessage (“”)) but i donot want to write for each word in the text..can you please tell me the way to solve this problem..
I have one more que to as but not now..
Thankyou and love to here back with your reply…Have a Great Day :-)
