1 | # SwipeBackDemo
2 | 为APP提供一个滑动手势来关闭当前页面,引入该方案对原有项目的改动较小,仅仅两个java文件。
3 |
4 | #特别感谢
5 | 该项目基于 [liuguangqiang's SwipeBack library](https://github.com/liuguangqiang/SwipeBack),在此对原作者表示感谢!
6 |
7 | #效果预览
8 | 
9 |
10 |
11 | 同时你也可以扫描二维码下载apk到手机里面进行体验【推荐】
12 | 
13 |
14 | #我的改动
15 | * 无需设置透明主题。
16 | * 避免因该主题而引起的副作用,例如:Activity切换动画失效、VideoView/SurfaceView变透明而无法显示内容、滑动关闭时部分手机会显示桌面。但是因此也割舍了界面随手势进行滑动的效果,目前的滑动效果类似新浪微博或者QQ的右滑关闭效果,具体可以看预览动态图片效果。
17 |
18 |
19 | * 滑动手势与界面内滑动控件不冲突。
20 | * 滑动的触发为边缘触发,默认是手势的ACTION_DOWN在屏幕边缘50个像素单位内可以触发滑动关闭操作,滑动距离超过一定距离则执行关闭当前Activity操作;如果ACTION_DOWN落点距离屏幕边缘大于50个像素单位,那么将触发操作交给界面View而不进行拦截.
21 |
22 | #如何使用
23 | * 将工程下载到本地,把`SwipeBackAppCompatActivity.java` 和`SwipeBackLayout.java`两个文件以及一些资源属性复制到你自己工程的对应目录或文件中,将你的`BaseActivity`继承至`SwipeBackAppCompatActivity`
24 | * 如果要实现Demo一样的Activity启动、退出动画,那么复制anim目录下的动画文件到自己的工程中,然后给自己的Activity配置动画主题即可
25 |
26 |
27 | `(为啥不支持Gradle dependencies引入,恩?哈哈哈,因为一是所需的文件就几个直接复制完事,二是我还没发布上传到jcenter啥的,也不打算传)`
