In my android app, I am retrieving data from mysql database, storing them in arraylist and displaying them in a listview. Now I want to make a perticular String bold, i.e. if in my arraylist, there's data something like, "Me: hello.." then in listview it should display as " **Me:** hello.. " . Here "**Me:**" will be first string in list but don't know in which row. I am not getting idea how to do this. Please someone help me..!!
