I know there is a lot of solutions suggested and most of them i got understand them clear use AutoCompleteTextView and i want usesearch view as small developer i try to find the solution to fit my goal , i have php script that bring these json data
[
{"fish_id":"1","fish_name":"Indian Mackerel","fish_weight":"2kg","price":"$10"},
{"fish_id":"2","fish_name":"Manthal Repti","fish_weight":"0.5kg","price":"$3"},
{"fish_id":"3","fish_name":"Baby Sole Fish","fish_weight":"5kg","price":"$12"},
{"fish_id":"4","fish_name":"Clam Meat","fish_weight":"1kg","price":"$7"},
{"fish_id":"5","fish_name":"Indian Prawn","fish_weight":"0.2kg","price":"$5"}
]
After long search i found this which bring data "fish_name" on auto suggestion and it works fine.The main goal is when i click item from auto suggestion list it has to display all related contents as brough by json, So i got this concept which bring data from sqlite database, the problem with it is it has to send request to the server based on selected item and bring results, so it kind annoying and time wasting.
So how can i bring all this data to the app and display "fish_name"on auto suggest and when item clicked it has to display all disired contents i mean "fish_name","price" and "fish_weight", so that i can increase app efficiency.
