是不是感觉Material风格的webView加载过程中head下面有一条线跟着网页的加载很酷对不，周末休息2天也随便撸一把，这里拿自己csdn的博客主页献丑了，哈哈。
不多说先来看下效果图：
1. 颜色渐变加载进度条（夜神模拟器）

这里写图片描述

绿色加载进度条（魅蓝note2）
看图说话：
上图是不是加载网页的时候会有一个进度条在横向加载，比以前网速不好的时候是一片空白给人的感觉友好多了是不，然后效果还不错。

实现思路

就是自己画一条进度线（大家应该都会吧）然后加载到WebView的上面，开始进度条是隐藏的，进度线初始值为1，然后为了效果好一点，初始少于10的进度都让它加载到10的位置，等进度到100的时候0.2秒后隐藏。

请记得添加网络权限：

说多了都是泪，快吃晚饭了，直接代码说话：

上面代码的功能就是画一条线（颜色可渐变也可不变色），暴露设置进度的方法给使用者，然后调用 invalidate()刷新进度。

注意：使用渐变时数组的长度和透明度数组长度必须一致，否则会报错的

步骤二：自定义封装webView

上面的代码就是把进度线加到webView里面，然后自定义WebChromeClient通过重写onProgressChanged（）方法调用 progressBar.setProgress(newProgress)来更新进度，进度到100时再隐藏，是不是思路很清晰，其他的就是一些webView的设置和封装这里都有清楚的注释，自己去看。

使用ProgressWebView加载网页

布局使用：

布局看起来是不是很清爽，对了，要的就是之效果：
实际使用也很简单：

总结：

自定义webView的加载虽然代码不是很难，但是思想还是得有的，好歹也算个自定义控件嘛。记住“只要思想不滑坡，方法总比困难多”。觉得说的不错的，写的也还过得去的给宝宝点个赞，顶一下也是对宝宝的支持给宝宝的动力。
