android webview goback Skip Method 302

 

very simple , look at the code

 

  

    @Override 
    public boolean onKeyDown(int keyCode, KeyEvent event) { 
        //判断是否可以返回操作 
        if (webView.canGoBack() && event.getKeyCode() == KeyEvent.KEYCODE_BACK) { 
            //获取历史列表 
            WebBackForwardList mWebBackForwardList = webView 
                    .copyBackForwardList(); 
            //判断当前历史列表是否最顶端,其实canGoBack已经判断过 
            if (mWebBackForwardList.getCurrentIndex() > 0) { 
                //获取历史列表 
                String historyUrl = mWebBackForwardList.getItemAtIndex( 
                        mWebBackForwardList.getCurrentIndex() - 1).getUrl(); 
                //按照自己规则检查是否为可跳转地址 
                //注意:这里可以根据自己逻辑循环判断,拿到可以跳转的那一个然后webView.goBackOrForward(steps) 
                if (!historyUrl.contains("s.click.taobao.com")) { 
                    //执行跳转逻辑 
                    webView.goBack(); 
                    //webView.goBackOrForward(-1) 
                    return true; 
                } 
            } 
        } 
        return super.onKeyDown(keyCode, event); 
    }
