I am using my own html code to show a html page in WebView.

  • 0

I am using my own html code to show a html page in WebView. I want to close the current activity on click of Cancel Button.
My Code is like:

public class WebHtml extends Activity
{
        String historyUrl, baseUrl;
        URL url = null;
        WebView mWebView;

String html = "<html>" + 
                "<body>" +
                "<form id='form1' name='form1' method='post' action='get.html'>" +
                "User <input type='text' name='user'>   <br />" +
                "Password <input type='password' name='user'>   <br />" +
                "<input type='submit' name='Submit' value='Login' />" +
                "<input type='button' value='Cancel' name='Cancel' onClick='javascript:window.close();'' />" +
                "</form>" +
                "</body>" +
                "</html>";

public void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
           // setContentView(R.layout.webview);
            mWebView = new WebView(this);
            mWebView.getSettings().setJavaScriptEnabled(true);  
            mWebView.loadDataWithBaseURL(baseUrl, html, "text/html", "utf-8", historyUrl);
            mWebView.setWebViewClient(new HelloWebViewClient());
            setContentView(mWebView);
        }

        @Override 
        public boolean onKeyDown(int keyCode, KeyEvent event) 
        { 
            if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) 
            { 
                mWebView.goBack();
                return true; 
            } 
            return super.onKeyDown(keyCode, event); 

        }

        private class HelloWebViewClient extends WebViewClient 
        { 
            public void onPageStarted(WebView view, String url, Bitmap bitmap)
            {
                Log.i("ShowForm", "onPageStarted()" + System.currentTimeMillis());
                historyUrl = url.toString();
            }
            public void onPageFinished(WebView view, String url)
            {
                Log.i("ShowForm", "onPageFinisheded()" + System.currentTimeMillis());
                baseUrl = url.toString();
            }

            @Override 
            public boolean shouldOverrideUrlLoading(WebView view, String url)
            { 

                view.loadUrl(url);
                return true; 
            } 
        }
}

The thing is I am not able to make it close the current form activity. I had used (window.close(), form.close(), javascript:window.close() on onClick but they showed no effect) & (I tried window.unload() which made exception) Moreover System.exit() shuts the app off at the time activity first starts.

Please suggest me what should I do.

Thanks,

Haps.

    Can you change the onClick of that cancel button to a URL? Something like onClick="document.location.href='http://exitActivity';".

    Then in your shouldOverrideUrlLoading method, you can intercept that URL and exit the app.

    @Override 
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
    if (url.contains("http://exitActivity")
        finish();  // close activity
    else
        view.loadUrl(url);

    return true; 
}
