Android 一個Activity中實現多視窗WebView
阿新 • • 發佈：2018-12-30
公司在弄一個類似瀏覽器的框架，主要頁面功能都是用h5，但是領導說要弄成多視窗的，而且還是隻在當前Activity中；
主體功能大概如此：頭部標題欄實現 標題、選單列表、多視窗顯示等
頭部以下就是一個WebView頁面，js互動實現頁面顯示。
聽到這個需求我挺頭疼，因為在一個Activity中實現多視窗還要實時的儲存每個頁面的狀態
查找了很多資料，跟我這個需求差不多的很少，所以只能自己來了。
最後勉勉強強實現了，做法很low，但是好歹也算是實現了，以此記錄一下：
廢話不多。
我的思路大概是這樣：
多視窗一般也不是無限制的，所以我定義了一個WebView[] 沒錯，定義一個WebView陣列，定義多視窗的上限為6 然後定義一個主WebView，將它存進WebView陣列中，而後面新建的也都存進WebView陣列中，顯示的時候將WebView[]陣列中的該項直接賦給主WebView， 是的，可以直接WebView = WebView[0];這樣賦值，同時定義一個總集合儲存每一個WebView的標題、連結等資料 每次切換同時把資料切換就可以了
下面上主程式碼：MainActivity.java —主頁面

還有一些小布局我就不一一貼上來了。
程式碼不難，實現的方式也很low，如果你們有更好的建議不妨互相討論討論
