我想使用WebView从MainActivity致电Intent来自string-array.xml，并在List item

中存储5个网址

我想要的内容：点击MainActivity中的WebView，它应该会打开[position]个活动并使用list-item它应该打开与之关联的确切网址string-array.xml: <string-array name="bookmark_urls"> <item>http://www.google.com</item> <item>http://www.android.com/</item> <item>http://www.toi.com/</item> <item>http://www.facebook.com/</item> <item>http://www.makemytrip.com/</item> <item>http://www.yatra.com/</item> </string-array> 。 代码说明： 

MainActivity.java

在String[] urls = getResources().getStringArray(R.array.bookmark_urls); Intent i = new Intent(MainActivity.this, Web_view.class); i.putExtra("urls", urls[position]); startActivity(i); 我称之为意图：

String urls

那么，我如何正确地将Webview拨打到下一个mainWebView.loadUrl("http://www.google.com");？

我想要这样的事情：  for

在你的webActivity中执行此操作

Intent i = getIntent();
String url = i.getStringExtra("urls");

 WebView mywebview = (WebView) findViewById(R.id.webView1);  
 mywebview.loadUrl(url);

请尝试使用我的技巧，它肯定会起作用

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

      WebView mainWebView = (WebView) findViewById(R.id.mainWebView);// pass here your webview id

      WebSettings settings = mainWebView.getSettings();
      settings.setJavaScriptEnabled(true);
      settings.setDomStorageEnabled(true);

      String urlStr = getIntent().getStringExtra("urls");
      mainWebView.loadUrl(urlStr);
}

WebView  ww = (WebView)findViewById(R.id.ww);
WebSettings webSettings = ww.getSettings();     
 webSettings.setJavaScriptEnabled(true);
 String WebURL=getIntent().getStringExtra("urls")
 ww.loadUrl(WebURL);

## Fragment with base Fragment ##

在Fragment的构造函数中创建传递URL，如下所示

mFragment = new Fragment1（）。newInstance（“”+ position，“url”）; 

 - Fragment1.class


package com.mydemo.fragment;

import android.content.Context;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.widget.ProgressBar;

import com.myadhaar.R;
import com.mydemo.Utils.Constants;
import com.mydemo.interfaces.OnFragmentInteractionListener;


public class Fragment1 extends BaseFragment {

    private static final String ARG_PARAM1 = "param1";
    private static final String ARG_PARAM2 = "param2";

    private String Fragmentposition;
    private String param2,URL;
    View rootView;
    private ProgressBar probressbar;
    WebView mWebView;

    private OnFragmentInteractionListener mListener;

    public Fragment1()
    {

    }


    public static Fragment1 newInstance(String Fragmentposition, String param2)
    {
        Fragment1 fragment = new Fragment1();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, Fragmentposition);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (getArguments() != null)
        {
            Fragmentposition = getArguments().getString(ARG_PARAM1);
            param2 = getArguments().getString(ARG_PARAM2);
            URL = param2;// Constants.Url[Integer.parseInt(Fragmentposition)];
        }
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        rootView = inflater.inflate(R.layout.fragment_adrno, container, false);
        initViews();
        setToViews();
        clickToViews();

        return rootView;
    }

    public void onActivityCreated(Bundle savedInstanceState)
    {
        super.onActivityCreated(savedInstanceState);

        setwebView(mWebView,probressbar,URL);
    }

    @Override
    public void initViews() {
        super.initViews();

        mWebView = (WebView) rootView.findViewById(R.id.webview);
        probressbar = (ProgressBar) rootView.findViewById(R.id.progressBar);

    }

    @Override
    public void setToViews() {
        super.setToViews();
    }

    @Override
    public void clickToViews() {
        super.clickToViews();
    }

    @Override
    public void setwebView(WebView webView,ProgressBar probressbar, String URL) {
        super.setwebView(webView,probressbar, URL);

    }


    public void onButtonPressed(Uri uri)
    {
        if (mListener != null)
        {
            mListener.onFragmentInteraction(uri);
        }
    }

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);

        if (context instanceof OnFragmentInteractionListener)
        {
            mListener = (OnFragmentInteractionListener) context;
        } else
        {
            throw new RuntimeException(context.toString()
                    + " must implement OnFragmentInteractionListener");
        }
    }

    @Override
    public void onDetach()
    {
        super.onDetach();
        mListener = null;
    }

        {
            mWebView.getSettings().setDisplayZoomControls(false);
        }

    }



}

 3. Inteface that should implent on BaseFragment.class


public interface FragmentViews {

    public abstract void initViews();
    public abstract void setToViews();
    public abstract void clickToViews();
    public abstract void setwebView(WebView webView, ProgressBar probressbar,String URL);

}
