推荐答案

随着web视图已被破坏并重新创建你将需要重新填充表单。您可以通过注入的JavaScript到Web视图做到这一点。

As the WebView has been destroyed and then recreated you will need to repopulate the form. You can do this by injecting javascript into the web view

例如以更新HTML元素的ID状态显示的文字

for example to update text displayed by HTML element id status

wevView.loadUrl（JavaScript的：document.querySelector（'＃地位）的innerHTML ='一些文本'）;

wevView.loadUrl("javascript:document.querySelector('#status').innerHTML = 'some text'");
