推荐答案

这可以通过在活动overrwriting的onSaveInstanceState（捆绑outState）和web视图调用saveState和处理：

This can be handled by overrwriting onSaveInstanceState(Bundle outState) in your activity and calling saveState from the webview:

@Override
protected void onSaveInstanceState(Bundle outState) {
    webView.saveState(outState);
}

然后恢复这在你的onCreate后的WebView已经重新充气课程：

Then recover this in your onCreate after the webview has been re-inflated of course:

@Override
public void onCreate(final Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.blah);
   WebView webview = (WebView)findViewById(R.id.webview);
   if (savedInstanceState != null)
      webview.restoreState(savedInstanceState);
   else
      webview.loadUrl(URLData)
}
