This code is working fine on my phone galaxy note 2(custom rom of note 4.. Android 4.4.4).By fine I mean I can type in edittext and popupwidow shows up after 3rd text(because of condition I have put) and I can select an option from the popupwindow. When I try to run the code on any other phone like galaxy grand then callback to ItemsDropdownOnItemClickListener is not registered and I can only scroll the popupwindow and keep on typing in edittext but cannot select any of the options in the popupwindow. If I set popupWindowItems.setFocusable(false) to true i.e popupWindowItems.setFocusable(true), and then as soon as I type 3rd letter in edittext,edittext looses focus and popwindow gains it. Now I can select anything.. But now I cannot continue to type in edittext.I have to manually select edittext and type.
Now I want that after tying 3rd word in edittext a popupwindow should appear(which currently is appearing) and edittext doesn't loose focus(so that i can continue typing).. Further if I select anything from popupwindow ,ItemsDropdownOnItemClickListener should be called which is currently being not called in other phones when popupWindowItems.setFocusable(false);
I am doing this to load data from sqlite database and show in popupwindow once the user types 3rd word. Any suggestion is recommended
Edit: Problem solved. Now using AutoComplete TextView
