This method no longer works as stated in the docs

原来的答复：

这可以通过overrwriting处理的onSaveInstanceState（包outState）在你的活动，并呼吁 saveState和从web视图：

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

   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:

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