我正在尝试使用http连接到该页面
帖子.我做一个用于创建的http帖子
一个webvIEw.我需要从webvIEw重定向到另一个页面.但是当单击“继续”按钮时会抛出异常.

我的代码是

public class ZhttpPostProjActivity extends Activity {    /** Called when the activity is first created. */    private WebVIEw mWebVIEw;    private ProgressDialog progressbar;    private static final String TAG = "ZhttpPostProjActivity";    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.web_vIEw);    mWebVIEw = (WebVIEw) findVIEwByID(R.ID.webvIEw);    WebSettings webSettings = mWebVIEw.getSettings();    webSettings.setJavaScriptEnabled(true);    webSettings.setDomStorageEnabled(true);    progressbar = ProgressDialog.show(ZhttpPostProjActivity.this, "",        "Loading...");    postData();    }    private final String URL_REGISTER = "https://www.paypal.com/checkout";    public voID postData() {    BufferedReader bufferedReader = null;    try {        List<nameValuePair> nameValuePairs = new ArrayList<nameValuePair>();        nameValuePairs.add(new BasicnameValuePair("username", "username"));        nameValuePairs.add(new BasicnameValuePair("password", "password"));        httpClIEnt httpclIEnt = new DefaulthttpClIEnt();        httpPost httppost = new httpPost(URL_REGISTER);        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs,            http.UTF_8));        httpResponse response = httpclIEnt.execute(httppost);        bufferedReader = new BufferedReader(new inputStreamReader(response            .getEntity().getContent()));        StringBuffer stringBuffer = new StringBuffer("");        String line = "";        String lineseparator = System.getProperty("line.separator");        while ((line = bufferedReader.readline()) != null) {        stringBuffer.append(line + lineseparator);        }        bufferedReader.close();        String webData = stringBuffer.toString();        Log.i(TAG + "web data : ", webData);        // String webData = new        // BasicResponseHandler().handleResponse(response);        Log.i(TAG, "httppost.getURI().toString(): "            + httppost.getURI().toString());        mWebVIEw.setWebVIEwClIEnt(new WebVIEwClIEnt() {        public boolean shouldOverrIDeUrlLoading(WebVIEw vIEw, String url) {            Log.i(TAG, "Processing webvIEw url click...");            vIEw.loadUrl(url);            return true;        }        public voID onPageFinished(WebVIEw vIEw, String url) {            Log.i(TAG, "Finished loading URL: " + url);            if (progressbar.isShowing()) {            progressbar.dismiss();            }        }        public voID onReceivedError(WebVIEw vIEw, int errorCode,            String description, String failingUrl) {            Log.e(TAG, "Error: " + description + " \n errorCode: "                + errorCode + "\n  failingUrl: " + failingUrl);        }        });        // mWebVIEw.loadUrl(httppost.getURI().toString());        mWebVIEw.loadData(webData, "text/HTML", "UTF-8");        mWebVIEw.loadDataWithBaseURL(httppost.getURI().toString(), webData,            "text/HTML", http.UTF_8, null);    } catch (Exception ex) {        ex.printstacktrace();    }    }

在WebvIEw中单击“继续”按钮时会抛出异常

解决方法:

像这样使用

WebVIEw webvIEw = new WebVIEw(this);setContentVIEw(webvIEw);byte[] post = EnCodingUtils.getBytes("postvariable=value&nextvar=value2", "BASE64");webvIEw.postUrl("http://www.geenIE.nl/AnHeli/mobile/ranking/demo/index.PHP", post);
