mWebView.goForward();//前進

mWebView.reload();  //刷新

[java] view plaincopyprint?

1. //點擊後退按鈕,讓WebView後退一頁(也能夠覆寫Activity的onKeyDown方法)    

2.         webview.setOnKeyListener(new View.OnKeyListener() {    

3.             @Override    

4.             public boolean onKey(View v, int keyCode, KeyEvent event) {    

5.                 if (event.getAction() == KeyEvent.ACTION_DOWN) {    

6.                     if (keyCode == KeyEvent.KEYCODE_BACK && webview.canGoBack()) {  //表示按返回鍵  

7.

10.   

11.                         //webview.goForward();//前進  

12.                         return true;    //已處理
