overridePendingTransition for sliding activities in and out smoothly

阅读更多关于 overridePendingTransition for sliding activities in and out smoothly

I'm having trouble figuring out how to slide activities in and out with a push of a button. What I want is for the user to push a button and then the screen slides. The way I want it is for the 1st activity (the one with the button) to slide out to the left while the new 2nd activity slides in from the right. With the below code, when the button is clicked, the 1st activity slides out to the right when I want it to slide out to the left. Then when it is done sliding, all that is remaining is a black screen for a split second and then the 2nd activity just appears and does not slide in. So the

Smooth transition from launch image to main view

阅读更多关于 Smooth transition from launch image to main view

Is it possible to implement a smooth transition when the app loads, from the launch image to the first view? The default behavior is on/off, with an immediate change: the launch image appears, then it instantaneously disappears to let the main view controller take place. I'd like to implement some fading or zooming in or out. Is this possible? Thank you! There's no framework support, but you can get that result if you do it yourself, manually. Depending on what your launch image is, and what your UI looks like, you can do it in different ways, but basically: make your first view controller

1.前言css3这个相信大家不陌生了，是个非常有趣，神奇的东西！有了css3，js都可以少写很多！我之前也写过关于css3的文章，也封装过css3的一些小动画。个人觉得css3不难，但是很难用得好，用得顺手，最近我也在过一遍css3的一些新特性（不是全部，是我在工作上常用的，或者觉得有用的），以及一些实例，就写了这一篇总结！希望，这篇文章能帮到大家认识css3。写这篇文章主要是让大家能了解css3的一些新特性，以及基础的用法，感觉css3的魅力！如果想要用好css3，这个得靠大家继续努力学习，寻找一些讲得更深入的文章或者书籍了！如果大家有什么其他特性推荐的，欢迎补充！大家一起学习，进步！看这篇文章，代码可以不用看得过于仔细！这里主要是想让大家了解css3的新特性！代码也是很基础的用法。我给出代码主要是让大家在浏览器运行一下，让大家参考和调试。不要只看代码，只看代码的话，不会知道哪个代码有什么作用的，建议边看效果边看代码。2.过渡过渡，是我在项目里面用得最多的一个特性了！也相信是很多人用得最多的一个例子！我平常使用就是想让一些交互效果（主要是hover动画），变得生动一些，不会显得那么生硬！好了，下面进入正文！引用菜鸟教程的说法：CSS3 过渡是元素从一种样式逐渐改变为另一种的效果。要实现这一点，必须规定两项内容：指定要添加效果的CSS属性指定效果的持续时间。2

阅读更多关于 Is there any useful Android Animation Tutorial for beginners? [closed]

Is there any good android animation tutorials to do in views or the transitions? A complete tutorial or guide may help alot. There are basically two type of animations: View Animation : With View Animation you can perform a series of simple transformations (position, size, rotation, and transparency) on the contents of a View object Drawable Animation : Drawable animation lets you load a series of Drawable resources one after another to create an animation. This is a traditional animation in the sense that it is created with a sequence of different images, played in order, like a roll of film

C: Good Habits re: Transitioning to C++

阅读更多关于 C: Good Habits re: Transitioning to C++

I've been learning C at Varsity for just shy of 2months now, and next year we'll be moving on to C++. Are there any habits I should get into with my C programming which will aid a transition to C++ in the future, or is it best to think of them completely separately ? When you learnt C then C++, did the way you coded in C change in any way ? There are already a lot of good answers. Mine will be more "mindset oriented". Data vs. Action! In C, everything is done to think like "Apply this effect to this data". In C++, this is more like "Data should behave". While the "Data should behave" can be

D3 Real-Time streamgraph (Graph Data Visualization) [closed]

阅读更多关于 D3 Real-Time streamgraph (Graph Data Visualization) [closed]

I would like a stream graph as in this example: http://mbostock.github.com/d3/ex/stream.html but I would like real time data entering from the right and have old data leave from the left, such that I always have a window of 200 samples. How would I do this such that I have the appropriate transitions? I tried changing the data points in the array a and then recreating an area as such data0 = d3.layout.stack()(a); but my transitions do not make it look like the chart is sliding across the screen. Thanks in advance. mbostock Try this tutorial : When implementing realtime displays of time-series

How hard will it be to transfer from my existing expertise in C# to building apps for the iPad/iPhone in Objective C? Remus Rusanu The language jump is OK. Once you get past the initial shock of [ and ] . However, the libraries and Framework shock will be substantial. The Cocoa and Touch frameworks are significantly lighter when compared with .Net Framework, so at least you can look at the bright side, you have less to learn. But their underlying philosophy, layout and historic evolution path is very different from the C#/.Net framework. Whether this will be easy or hard, is difficult to
