我有一个列表视图即可从urpre中提取共享偏好数据，在每个列表视图行中都有一个我要发送到另一个活动的webview中的网址。这是我的网页浏览活动

WebView webView;

String DEFAULT_URL = "https://www.google.co.in/";
ProgressDialog progressBar;
String YourWebName = "Put Here";
ArrayList<String> list;

String  bundle=null;
SharedPreferences prefs;
SharedPreferences.Editor edit;
Set<String> set = new LinkedHashSet<String>();


/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    webView= (WebView)findViewById(R.id.webView);
    webView.getSettings().setLoadsImagesAutomatically(true);
    webView.getSettings().setJavaScriptEnabled(true);
   webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
    Intent i = getIntent();
    String url = i.getStringExtra("link");

    prefs=this.getSharedPreferences("preferences",Context.MODE_PRIVATE);
    edit=prefs.edit();
    list = new ArrayList<String>();

    webView.setWebViewClient(new MyWebViewClient());

    if (getIntent().getExtras()!=null &&getIntent().getExtras().getString("com.parse.Data")!=null){
        bundle=getIntent().getExtras().getString("com.parse.Data");
        parseJson(bundle);
        Log.e("notificationData", ""+bundle);
    }else{
        showProgressBar();
        webView.loadUrl(DEFAULT_URL);
    }


}

private class MyWebViewClient extends WebViewClient{

    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

    public void onPageFinished(WebView view, String url) {
        if (progressBar!=null && progressBar.isShowing()) {
            progressBar.dismiss();
        }
    }

}

，这是我的列表视图活动

super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_notifications);

    no_notifications=(TextView)findViewById(R.id.no_notifications);

    prefs=this.getSharedPreferences("preferences",Context.MODE_PRIVATE);
    //edit=prefs.edit();
    listview=(ListView)findViewById(R.id.listView);

     listview.setOnItemClickListener(new OnItemClickListener() {

       public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
           Object o = listview.getItemAtPosition(position);
           String str=(String)o;
              Toast.makeText(ListOfNotifications.this, "You have chosen: " + " " + str.getLabel(), Toast.LENGTH_LONG).show();
           Intent i = new Intent(ListOfNotifications.this,ParseStarterProjectActivity.class);

            i.putExtra("link", o.getText());

            startActivity(i);
       }
     });
    if (getIntent().getExtras()!=null &&getIntent().getExtras().getStringArrayList("listData")!=null){

    listData=getIntent().getExtras().getStringArrayList("listData");

    if (listData!=null && listData.size()>0){
        listview.setVisibility(View.VISIBLE);
        no_notifications.setVisibility(View.GONE);
        adapter= new ListAdapter(ListOfNotifications.this, R.layout.listview_row,listData);
        listview.setAdapter(adapter);

    }else{
        listview.setVisibility(View.GONE);
        no_notifications.setVisibility(View.VISIBLE);
    }

    }

将url传递给list活动中的intent到webview活动。从webview活动中获取该url的url，并将该url传递到webview的String str = "Here \" is one final \" example"; Pattern regex = Pattern.compile("[^\\s\"']+|\"([^\"]*)\"|'([^']*)'"); Matcher regexMatcher = regex.matcher(str); while (regexMatcher.find()) { System.out.println(regexMatcher.group()); }。

这样可行。
