Android horizontal scrollview behave like iPhone (paging)

由 不羁的心 提交于 2019-11-26 15:10:07
问题 I have a LinearLayout inside a HorizontalScrollView. The content is just a image. While scrolling, I need to achieve the same behavior you get when setting the paging option on a the iPhone equivalent of the HSW (scrolling the list should stop at every page on the list, not continue moving). How is this done in Android? Should I implement this features by myself or there is a particular property to set or a subclass of HSV to implement? 回答1: I came across a nice solution here: Horizontal

MongoDB - paging

由 爱⌒轻易说出口 提交于 2019-11-26 15:08:08
When using MongoDB, are there any special patterns for making e.g. a paged view? say a blog that lists the 10 latest posts where you can navigate backwards to older posts. Or do one solve it with an index on e.g. blogpost.publishdate and just skip and limit the result? Using skip+limit is not a good way to do paging when performance is an issue, or with large collections; it will get slower and slower as you increase the page number. Using skip requires the server to walk though all the documents (or index values) from 0 to the offset (skip) value. It is much better to use a range query (+

How to use GWT 2.1 Data Presentation Widgets

由 你离开我真会死。 提交于 2019-11-26 11:55:46
问题 At the 2010 Google IO it was announced that GWT 2.1 would include new Data Presentation Widgets. 2.1M is available for download, and presumably the widgets are included, but no documentation has yet surfaced. Is there a short tutorial or example for how to use them? I\'ve seen a rumor that CellList and CellTable are the classes in question. The Javadoc for them is riddled with lots of TODOs, so quite a bit is still missing in terms of usage. 回答1: Google I/O 2010 - GWT's UI overhaul javadocs

How to do page navigation for many, many pages? Logarithmic page navigation

由 夙愿已清 提交于 2019-11-26 09:07:47
问题 What\'s the best way of displaying page navigation for many, many pages? (Initially this was posted as a how-to tip with my answer included in the question. I\'ve now split my answer off into the \"answers\" section below). To be more specific: Suppose you\'re displaying a set of records to the user, broken up into fixed-size pages (like the results of a Google search, for example). If there are only a few pages, you can display a page navigation area at the end of the results that might look

Paging SQL Server 2005 Results

问题 How do I page results in SQL Server 2005? I tried it in SQL Server 2000, but there was no reliable way to do this. I\'m now wondering if SQL Server 2005 has any built in method? What I mean by paging is, for example, if I list users by their username, I want to be able to only return the first 10 records, then the next 10 records and so on. Any help would be much appreciated. 回答1: You can use the Row_Number() function. Its used as follows: SELECT Row_Number() OVER(ORDER BY UserName) As RowID,

How to get distinct results in hibernate with joins and row-based limiting (paging)?

由 ﹥＞﹥吖頭↗ 提交于 2019-11-26 07:56:24
问题 I\'m trying to implement paging using row-based limiting (for example: setFirstResult(5) and setMaxResults(10) ) on a Hibernate Criteria query that has joins to other tables. Understandably, data is getting cut off randomly; and the reason for that is explained here. As a solution, the page suggests using a \"second sql select\" instead of a join. How can I convert my existing criteria query (which has joins using createAlias() ) to use a nested select instead? 回答1: You can achieve the

sorting and paging with gridview asp.net

由 99封情书 提交于 2019-11-26 06:29:31
问题 I\'m trying to get a gridview to sort and page manually with no success. The problem is that when a user clicks the column they want to sort, it sorts that page, but doesn\'t sort the datasource (dataview) behind the gridview. So when they progress to a different page, their sort is lost. Pretty much I\'m looking for a sort that will actually sort the datasource behind the gridview. Here is what I have so far: protected void GridView_OnSort(object sender, GridViewSortEventArgs e) { String
