问题描述

我正在制作一个图片库应用程序.我目前有一个底部带有文本视图的图像视图.目前它只是半透明的.我想让它淡入，等待 3 秒，然后淡出 90%.将焦点放在它上面或加载新图片将使其重复循环.我已经阅读了十几页并尝试了一些事情，但没有成功.我得到的只是淡入和即时淡出

I am making a picture gallery app. I current have a imageview with a text view at the bottom. Currently it is just semitransparent. I want to make it fade in, wait 3 second, then fade out 90%. Bringing focus to it or loading a new pic will make it repeat the cycle. I have read thru a dozen pages and have tried a few things, no success. All I get is a fade in and instant fade out

推荐答案

您可以使用额外的动画对象(不修改其 alpha)来防止即时淡出，为您的淡入效果设置 animationListener 并启动在淡入的动画结束时额外的动画对象，然后在额外的动画对象的动画结束时开始淡出，试试下面的链接，它会有所帮助..

You can use an extra animation object (which doesn't modify its alpha) to prevent the instant fade out, set animationListener for your fade-in effect and start the extra animation object in the on animationEnd of the fade-in, then you start fade-out on animation end of the extra animation object, try the link below, it'll help..
