Toggle button visibility in android activity
I have an activity with two play and pause buttons (currently invisible) and a seekbar. When I press the play button, the pause button should become visible, and when I press the pause button it should turn invisible. How would I do that? import android.media.MediaPlayer; import android.os.Bundle; import android.app.Activity; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.SeekBar; import android.widget.SeekBar.OnSeekBarChangeListener; public class MainActivity extends Activity implements Runnable, OnClickListener,
Error when I use SpecialCells of AutoFilter to get visible cells in VBA
My main goal is to copy the visible cells of an autofilter and later copy the dimensions of the visible cells to the new sheet. I am using this code: Sheets(1).AutoFilterMode = False Sheets(1).Range("A1:A1").AutoFilter Field:=columnaNumeroIntervalo, criteria1:=CDec(paramCantidadCriterio) Sheets(1).Range("A1:A1").AutoFilter Field:=columnaNumeroIntervaloUnidades, Criteria1:=paramUnidadesCriterio MsgBox AutoFilter.Range.SpecialCells(xlCellTypeVisible)(2, 11).Value With the last line I want to check the value o a cell. If I use Cells(2,11) instead of SpecialCells I can see that cells have all the
Always show FooterTemplate, even no data
Is there a short way to make a FooterTemplate (in a GridView) always visible, even when DataSource is empty? If you want it to always display, regardless of content, can't you just put the footer html outside the GridView , instead of in the FooterTemplate ? If that's not an option for some reason, then you can either add an null row to your data source if it's empty , or subclass the GridView & override the default behaviour . Those are the only options I'm aware of (although its been a while since the last time I used a GridView ). Aximili I was having trouble with this as well. The link
JQuery: fire action when element is in view
问题 In the footer of my site I'm using counUp.js (Link: http://inorganik.github.io/countUp.js/ ) to count up three numbers. I added this code at the bottom of the site: <script type="text/javascript"> var c1 = new countUp("upnum1", 1, 27, 0, 4); var c2 = new countUp("upnum2", 1, 10, 0, 4); var c3 = new countUp("upnum3", 1, 27, 0, 4); var c4 = new countUp("upnum4", 1, 1000, 0, 4); window.onload = function() { c1.start(); c2.start(); c3.start(); c4.start(); } </script> This works well, but starts
jQuery detect visible but hidden elements
问题 This seems like it should be fairly easy - but I can't find the right selector for it According to the docs (http://api.jquery.com/hidden-selector/ and http://api.jquery.com/visible-selector/)... Elements can be considered hidden for several reasons: An ancestor element is hidden, so the element is not shown on the page. What I want to detect is "this element is visible, but is contained in a hidden parent". Ie, if I made the parent visible, this element would also be visible. 回答1: If this is
How can you tell if a View is visible on screen in Android?
问题 I want to check if a View within a ScrollView is currently visible in Android. I am not checking if it is focused on yet but if it is currently being displayed on screen. Is there a method in View that can tell me if the view is currently visible? 回答1: This code works for me: public static boolean isVisible(final View view) { if (view == null) { return false; } if (!view.isShown()) { return false; } final Rect actualPosition = new Rect(); view.getGlobalVisibleRect(actualPosition); final Rect
Scroll if element is not visible
how to determine, using jquery, if the element is visible on the current page view. I'd like to add a comment functionality, which works like in facebook, where you only scroll to element if it's not currently visible. By visible, I mean that it is not in the current page view, but you can scroll to the element. Live Demo Basically you just check the position of the element to see if its within the windows viewport. function checkIfInView(element){ var offset = element.offset().top - $(window).scrollTop(); if(offset > window.innerHeight){ // Not in view so scroll to it $('html,body').animate(
Android: Getting a count of the visible children in a listview
Is there are way to get a count of the number of visible listview children? I have a listview with info linked to a database that can change at any time. When the database is changed, I send out a broadcast notifying the ui class handling the list view. The child element relating to the changed data is then updated. I am achieving this by giving each listview item a tag, and then iterating over the listviews to find the row matching the tag from the broadcast. I want to only iterate over the visible children. There is no need for me to manually update views that are not visible, as they will
