I want to display some conditional data in List view when user request or click on button. Each list row has two value one value is name and 2nd its description. When User press button it fire command and fetch information from peripheral and match all value with different condition one by one, as a Conditions are match with value it put one list row value in adapter after all conditions check it will assign adapter to list view, then display all adapter data will be display in list view.
This is my Code
