Android CoordinatorLayout + AppBarLayout(向上滚动隐藏指定的View)

由 ⅰ亾dé卋堺 提交于 2020-03-22 03:58:51
在新的Android Support Library里面,新增了CoordinatorLayout, AppBarLayout等. 实现的效果: 向下滚动RecylerView,Tab会被隐藏,向上滚动RecylerView,Tab恢复出现. 这么做的好处在于,用户能有更多的空间位置去看列表里面的内容. 实现步骤: <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation=

D3 mousewheel zoom direction

由 最后都变了- 提交于 2020-03-21 07:04:30
问题 I'm trying to create some custom zoom functionality in d3.js. Currently the zoom is triggered on a single click and zooms in to focus only on the area that was clicked on. Currently my code has a function zoom(d) that does exactly what it needs to. There is also a var zoomTransition which resides inside zoom() and is responsible for much of the functionality. I'm unfortunately unable to share much of my code. The zoom needs to also occur on a mouse scroll. The difficulty I'm having is that

How to scroll DataGridView in pixel increments

由 橙三吉。 提交于 2020-03-14 15:43:45
问题 My original approach was to enclose my DataGridView inside a panel, set its height outside the boundary of the panel and then change control panel's scroll bar position. However, I just found out that the number of rows inside my DataGridView would reach 2000, which forces me to size the DataGridView to at least: 65px (row height) x 2,000 = 130,000px. The maximum allowed size for a DataGridView control on my 64bit machine is 65,535. Anyone can think of a way around this issue? 回答1: Hmm, no,

Is there an event that fires on changes to scrollHeight or scrollWidth in jQuery?

由 白昼怎懂夜的黑 提交于 2020-03-13 07:12:10
问题 I'm using JQuery to design an application where the user can drag elements inside of a div that automatically adds scrollbars and expands the scrollHeight/scrollWidth as needed. I need to fire off an even when the scrollHeight and scrollWidth of the container div are changed. No, don't want to use the scroll event because 1) scroll doesn't get fired when you just start dragging an element to the edge and the scrollHeight/scrollWidth change. 2) scroll fires when the scrollHeight/scrollWidth

Selenium / Python - How to access / count all elements inside a container that has virtual scrolling

由 徘徊边缘 提交于 2020-03-05 06:07:05
问题 I have a cdk-virtual-scroll-viewport container with many elements in it which means not all of its elements are rendered at once. If I scroll, I get more elements and 'lose' the previous ones. What I want to do is to count the children of this container and process its data. I have already done the part for counting and processing and it is working as I had checked with elements that fit in this container without needing to scroll. The problem I have is that because this container doesn't

Scrollable Panel snap to elements on Scroll

问题 Is there a way inside a scrollable div to snap to elements as the user scrolls. For example if we have CSS such as .container { height: 300px; width: 200px; overflow: auto } li { height: 40px; width: 100 % ; } and HTML as <div class="container"> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> <li> test </li> </div> So from that the container should
