I have a list of tokens and the user needs to create a list of a subset of these quickly. I now have keyboard entry and a display of the list but the keyboard covers up the list. My user wants to click on the tokens rather than type them in. There might be 500 tokens so a listview seems unworkable. They can be different lengths from one character to 20 so a gridview doesn't seem like a good idea. All I can think of is to keep the list in a textview and have the user click on one and pop up a alert asking if he wants to enter that token. The list is scrollable.
Basically, I want the user to click on a word in a textview and have the java know what word that was. All words are separated by commas.
For example, here is one set that might be displayed
7W, 4F, 2R, 5K, 73, 3J, 6F, 2F, 7M, 21, 5D, 1H, 5C, 24, 7Y, 4D, 70, 1E, 3P, 2C, 4B, 3E, 5A, 4G, 5E, 6H, 6N, 7J, 7S, 2B, 41, 4H, 3H, 2A, 3B, 3F, 40, 4N, 2J, 3C, 22, 5M, 44, 7Z, 3U, 3L, 3Q, 7A, 72, 4V, 7X, 26, 1D, 4M, 6D, 5R, 6B, 6K, 7U, 7V, 7T, 7P, 7L, 4R, 7G, 7E, 7B, 3X, 7F, 5J, 5L, 3T, 7R, 3K, 2T, 43, 71, 5N, 1C, 7H, 5B, 3M, 6J, 6M, 6R, 5H, 1F, 1L, 7Q, 6P, 7C, 6A, 4T, 3R, 46, 1N, 1K, 4Y, 5F, 7K, 6S, 5Q, 2H, 42, 4X, 1A, 1B, 33, 3N, 2K, 3G, 4A, 5G, 30, 4E, 7N, 4S, 3S, 5S, 3D, 20, 4K, 1J, 32, 2X, 31, 4Q, 45, 4Z, 1G, 74, 6G, 4C, 4U, 3Z, 4W, 5P, 25, 1M, 6C, 3V, 3Y, 3A, 6E, 4P, 7D, 4J, 4L, 3W, 6L, 6Q, Thorn Knoll, North Thorn, Hook, Black Jack, Castle Point, Calshot Spit, Bourne Gap,
The user needs to be able to select the desired 10 items in under 30 seconds (he gets the list just a few minutes before the start of a race).
The text entry that he needs to enter might look like this:
Route Name, 30,24,4R, 3E, 6Q, 3N, Thorn Knoll, 5G
What is the best way to do this?
Here is what I have now
What he wants is to just click on the tokens.
Here is some text code to prove the concept. Thanks to Vaghela M.R - Mobile Devloper for the link.
