Android动态布局实现

来源：互联网发布：Linux设置启动程序字体编辑：程序博客网时间：2024/05/20 05:08

最近在开发项目时需要用到动态布局，在这里把动态布局实现方式给大家做一下分享，可能有些同学会问什么是动态布局？动态布局比较适合用到应用的首页，可以灵活的展示各种海报，具体来说就是海报的大小，每页的布局都是随意修改的，具体实现方法：

1. 服务端做好对应的布局映射后，把页面的信息通过Json形式存储到db

2. 客户端需要展示时，去服务端请求布局信息，从缓存中拿到对应的Json数据

3. 拿到数据后客户端使用addView方法，根据参数不断的添加每个view，其实只是逻辑稍微复杂些，实现起来并没什么大难度，生成view后再为每个view绑定点击事件就好了，下面分享一下后台的Json数据给大家参考
