十三. 远程行为
原标题:Webview Strange behaviour

我正在开发一种roid,这里我很少混淆,首先,在网上浏览中装上了html表格的数据。 之后,与我第一页链接的其他页面相去甚远。 我现在回到第1页,在“应对”方法中使用了以下代码,但在第1页上显示我空洞的网址。 如果情况如下,则避免出现这种情况,但结果仍然相同,

if(webview.canGoBack() == true)
{
    webview.goBack();
    if(!webview.canGoBack())
        webview.loadDataWithBaseURL("http://xyz.com/feed/", data, "text/html", "utf-8", null);
}
// if now on fist page then do the following
else if(activityno==2) {
    Intent fav = new Intent(Views.this, FavroiteShow.class);
    startActivity(fav);
}
//on first page and activity no is not 2 then do the following
else
   finish();
}

如果网上浏览能够回来,那么简言之,别无选择。 否则,如果网络调查不能回头来,那么就没有活动,而是在其中填写。 i 想补充一点,即如果网站概览进入第一页。 之后,无论活动没有什么,都装上我的数据。

where am i wrong. Thanks

提一下。

 if(webview.canGoBack() == true)
           webview.goBack();
   else  //if there is no history available
         webview.loadDataWithBaseURL("http://xyz.com/feed/", data, "text/html", "utf-8", null);
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    // TODO Auto-generated method stub
    if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
        webview.goBack();
        return true;
    } else if (!webview.canGoBack()) {
        webview.loadDataWithBaseURL("http://xyz.com/feed/", data,
                "text/html", "utf-8", null);
        // if now on fist page then do the following
        if (activityno == 2) {
            Intent fav = new Intent(Views.this, FavroiteShow.class);
            startActivity(fav);
        }
        else {
            finish();
        }
    }

    return super.onKeyDown(keyCode, event);
}

I have used overriden Class onKeyDown. and Checkes here the KeyEvent.

Hope this Works for you..
