I am doing a google map project where I have to fetch the data (title and snippet description) from Array List (which is retrieved from server) and display it in title and snippet dynamically. Since the description in the snippet is lengthy, the whole description is not displayed. The following is my code.
I am able to get a title and a snippet when I tap the marker. What I need is, the snippet should show the lengthy description which comes from server. At present what happens is, there is one title line and one snippet line. The description is shown half in the snippet. If I am not clear please let me know. Need to solve this.
