我正在使用Android应用程序。我希望只能从网站加载项目并隐藏一些标签(页眉,页脚,搜索面板)。我使用了Webview和Jsoup
。一切正常。但是当我点击某个项目时,在新页面中将再次打开页眉/页脚。如何使用此代码隐藏页眉和页脚?
public class MainActivity extends AppCompatActivity {
WebView webview;
String url="http://hut.az/";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webview= (WebView) findViewById(R.id.webview);
new MyAsynTask().execute();
}
private class MyAsynTask extends AsyncTask<Void, Void, Document> {
@Override
protected Document doInBackground(Void... voids) {
Document document = null;
try {
document= Jsoup.connect(url).get();
document.getElementsByClass("header1").remove();
document.getElementsByClass("topbar clearfix").remove();
document.getElementsByClass("mapandslider").remove();
document.getElementsByClass("footer1").remove();
document.getElementsByClass("copyright").remove();
} catch (IOException e) {
e.printStackTrace();
}
return document ;
}
@Override
protected void onPostExecute(Document document) {
super.onPostExecute(document);
webview.loadDataWithBaseURL(url,document.toString(),"text/html","utf-8","");
webview.getSettings().setCacheMode( WebSettings.LOAD_CACHE_ELSE_NETWORK );
webview.setWebViewClient(new WebViewClient(){
private WebView view;
private WebResourceRequest request;
@Override
public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
this.view = view;
this.request = request;
view.loadUrl(url);
return super.shouldOverrideUrlLoading(view, request);
}
});
}
}
}

这是因为您在/channel
中打开了一个新页面,然后您没有删除该新网页中的标记,您需要做的就是将代码更改为
Webview
