如何使用网络视图？

Question

  String  fbid = getIntent().getStringExtra("id");//Getting this value from previous screen

     Log.e( "What I am getting : " + fbid);


    final String url = "https://www.fbbexample.com/abc/"+fbid;  //**not working**

Log.e( "url I am getting : " + url); Log value:  https://www.fbbexample.com/abc/59



// final String url2 = "https://www.fbbexample.com/abc/"+59;  //**this is working**

   //  Log.e( "url2 I am getting : " + url2);  Log value:  https://www.fbbexampl.com/abc/59

    webView = (WebView) findViewById(R.id.webView);       



    webView.getSettings().setJavaScriptEnabled(true);

    webView.loadUrl(url);

    webView.getSettings().setBuiltInZoomControls(true);

    webView.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            // webView.getSettings().setBuiltInZoomControls(true);
            return true;
        }
    });
}
}

我面临的是，当我对字符串“fbid”进行硬编码时，它可以工作，当我按照上面提到的方式尝试它时，然后出现空白屏幕.. ....

Intent 意图 = new Intent(getContext(), SingleFbb.class);
intent.putExtra("id",idno);

试试这个

      public class ShowSubjectListItemsInWebView extends ActionBarActivity {
        private WebView webView;       

        private ProgressDialog dialog;
        private String url;


        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_show_subject_list_items_in_web_view);
            this.initViews();
            String  fbid = getIntent().getStringExtra("idmindmaps");
            url= "https://www.fbbexample.com/abc/"+fbid; 
            loadWebView(url);
        }

        //initializes all views
        private void initViews() {
            webView = (WebView) findViewById(R.id.filesWebView);
        }

        //show Url in WebView
        public class myWebClient extends WebViewClient {
            @JavascriptInterface
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                // TODO Auto-generated method stub
                super.onPageStarted(view, url, favicon);
                dialog = new ProgressDialog(ShowSubjectListItemsInWebView.this);
                dialog.setProgressStyle(android.R.style.Widget_ProgressBar_Small);
                dialog.setCancelable(false);
                dialog.setMessage(Constant.KEY_PLEASE_WAIT);
                dialog.show();
            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                // TODO Auto-generated method stub
                view.loadUrl(url);
                return true;
            }

            @Override
            public void onPageFinished(WebView view, String url) {
                // TODO Auto-generated method stub
                super.onPageFinished(view, url);
                if (dialog.isShowing()) {
                    dialog.dismiss();
                }
            }
        }

        public void loadWebView(String url) {
            webView.setWebViewClient(new myWebClient());
            webView.getSettings().setJavaScriptEnabled(true);
            webView.getSettings().setBuiltInZoomControls(true);
            webView.getSettings().setUseWideViewPort(true);
            webView.getSettings().setLoadWithOverviewMode(true);
            webView.getSettings().setDomStorageEnabled(true);
            webView.setVisibility(View.VISIBLE);
            webView.loadUrl(url);
        }

   }

Answer 2

试试这个。这将删除空格，

String url = "https://www.fbbexample.com/abc/"+ URLEncoder.encode(fbid,"UTF-8");

您也使用了错误的键从可渗透的屏幕中获取价值。 代码中的正确键是“idmindmaps”，所以使用它。

String  fbid = getIntent().getStringExtra("idmindmaps");
