Write an Android application

Hi, My name is Amit Saxena. I'm an android developer. i want to make filter for my app which includes different categories like: Brands, Location, price etc. whenever user clicks any of these categories a ListView appears which shows category result with check boxes. suppose user clicks brands and then chooses any number of brands, then if he clicks on location and chooses any number of locations. After clicking filter button a link should be created. link should appear like: [login to view URL]^145^144&location=2&usertype=1&pricerange=bet1000to10000.. here brandname,location, usertype and pricerange are the keywords for different categories and these numbers are key's of different categories.. some of categories numbers are coming from API and some numbers i assign for some categories. for assigning/storing numbers i used ArrayList<String>. if a user clicks any of category result list checkbox, assigned number/text+num with there respective position should append on link. Note: i am also not able to put price range text+num in arraylist or not able to use it. 2nd issue: not able to do facebook, google and linkedin login in android 7 devices. also not able to put all these logins in 3 pages of my app. 3rd issue: load more in recycler view is not happening. I'm attaching screen shot of my filter. Can you help me in these issues? Thank You, Amit Saxena.
