Can I set viewpager's item width?

I hope I can show 3 items in a page of viewpager, but now I only could set viewpager's padding value and margin value, so it only show one item in a page of viewpager. How can I set the item width? I think if I can set more little width of item, the viewpager will show more items in a page.

Can anyone help me with this logic test?

I was given the following question in an interview, and I came up with the code below to compute the sum the code works and is correct, but I was told that this was a logic question and they weren't looking for the source code, can anyone shed a light on this? did they want me to write the pseudo code perhaps?

Compute the following sum:
1/2 + 1/4 + 1/8 + ... + 1/1048576

private static double computeSum()
 
 {
     double x = 0.0;
 
     for(double i=2; i<=1048576; i*=2)
     {
 
             x += (1 / i);
 
     }
 
     return x;         
 }

Ajax doesn't trigger server action

I am trying to trigger action via ajax but it doesn't call from some reason. Is my js code fine?

@Html.ActionLink("LIKE", "LikeComment", "Comments", new { id = 1985 }, new{@class = "likeButton"})
 
 $(document).ready(function () {
         $(".likeButton").click(function () {            
             $.ajax({
                 url: $(this).data("action-url"),
                 cache: false,
                 success: function (html) {
                     alert('ss');
                 }
             });
             return false;
         });
     });

Execute functions in order

I want to execute 3 functions in a certain order and I do this:

function nextPage() {
     var loading_temp = $('#loading_temp');
 
     loading_temp.show()
         .queue(function() {
             nextPage980()
                 .queue(function() {
                     loading_temp.hide();
                     $(this).dequeue();
                 });
             $(this).dequeue();
         });         
 }

The '#loading_temp' shows up and then the function executes, but the last function (hide the loading gif) does not execute!

Chrome gives this error: Uncaught TypeError: Cannot call method 'queue' of undefined

The nextPage980() function is this:

function nextPage980() {
         var ajax_heading = $('#ajax_heading');          
         var cur_heading = $('#cur_heading');            
         var temp_heading = $('.temp_heading');
             var temp_heading_first = temp_heading.filter(':first');         
         var loading_temp = $('#loading_temp');
 
         var htmlHeader = "?????????????";           
 
         ajax_heading.attr('class', 'next_temp');        
         cur_heading.css({'margin-right' : '20px'}).after('<div id="cur_heading" class="temp_heading" data-tempPos="2"><h1 class="page_heading"><span class="heading_span">' + htmlHeader + '</span></h1></div>')        
             .queue(function() {
                 ajax_heading.animate({'margin-left' : '-1000px'}, 1000, 'easeInExpo')               
                     .queue(function() {
                         temp_heading_first.remove();                        
                         cur_heading.removeAttr('style');                        
                         ajax_heading.attr('class', 'cur_temp').removeAttr('style');                                                     
                         $(this).dequeue();
                     });
                 $(this).dequeue();
             });     
     }

Thanks in advance!
