流式布局FlowLayout的动态添加删除

2017-05-17 17:24 459 查看

前言

flow layout, 流式布局, 这个概念在移动端或者前端开发中很常见,想淘宝,京东都有,之前公司项目有用到一个流布局显示关键词并动态添加的效果,于是科补并实现了一下。

展示

因为软键盘的问题,本来是想上静态图的,但是强迫症上来了,还是搞了个动态图,就是有点失真,抱歉抱歉,另外求推荐一款截屏软件啊!!!



里面写死了是textview、当然有需求的小伙伴们可以自己改一下,比较简单。

分析

我们来看看他需要些什么,不难看出

1. 左右间距,行间距

2. 子view的点击事件,长按事件

3. 点击的同事判断是否是最后一个添加按钮,

4. 计算每个子view的高度,取最高的,

5. 计算每个子view的宽度,叠加超过控件宽度则需要换行

6. 点击事件的回调,1:点击添加按钮的回调,2:点击其他按钮的回调返回当前选中的list字符串集合,便于通知服务器

7. 长按事件点击确定删除标签的回调,便于通知服务器

接下来就只是上代码了,因为你们搬砖我也是个初窥,所以注释比较全,就不多做解释了

注释全在代码中了,提一下,这里区分点击事件用的的是settag的方法。还有就是ShowDialog方法是之前博客里面封装的一个自定义弹出框,

自定义属性

<declare-styleable name="XCFlowLayout">
<!--横纵向的间距-->
<attr name="h_space" format="dimension" />
<attr name="v_space" format="dimension" />
</declare-styleable>


到这里代码段就结束了

忘记activity里面的代码了我去

XCFlowLayoutActivity.java

}

// 监听软键盘弹出收起的
@Override

}

由于今天突发琐事较多,再加上编辑器卡,瞬间把想好咋写的就给我整没了,一股生无可恋的赶脚涌了上来!!!,那就先这些了,另外有个学习讨论的群!大家一起讨论哈哈!一起开车,与君共勉!。群号:188089649!转载请注明出处!谢谢! 本来按照国际惯例是有个Demo的,但是下班了,电脑编辑器卡了,来不及上,等闲暇时间在补,当然也可以加群找我要哦《搬砖小能手》

应一个小伙伴的要求写了个demo,于是顺便上传一下!,让你们久等了,FlowLayoutDemo

修改了下onMeasure的代码,修改后的demo(下载了原来demo小伙伴注意一下):FlowLayoutDemo
