我想在 webview android 上部分查看网页并从网页中删除一些 div 元素。我有一个这样的网页
<!DOCTYPE html>
<body>
<div id="a"><p>Remove aa</p></div>
<div id="b"><p>bb</p></div>
</body></html>
现在我想从网页中删除 id 为“a”的 div。
我尝试用 Jsoup 对其进行编码,但我还不够好,无法完成。请看我的完整代码:
import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import android.os.Bundle;
import android.app.Activity;
import android.graphics.Bitmap;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class CustomWebsite extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom_website);
Document doc;
String htmlcode = "";
try {
doc = Jsoup.connect("http://skyasim.info/ab.html").get();
doc.head().getElementsByTag("DIV#a").remove();
htmlcode = doc.html();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
webView = (WebView) findViewById(R.id.webView_test);
webView.setWebViewClient(new myWebClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("htmlcode");
}
public class myWebClient extends WebViewClient
{
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
}
