OK so it does not need to be webview but that's the closest I have
gotten to solving my problem. (going on 2 weeks now).
ok so right now I am using a webview to go and see a page. On that
page is a hidden input tag with an id and value.
I need to pull that value and use it in java. Eventually I need to
send something also. I have this all working in a blackberry webworks
app using javascript and ajax.
I think I'm close but I cant seem to modify my code to get the right
result. with this code I can get all the html on the page but not
just the one thing I want. This is put into an alert.
How do I get just the value and then how do I get it so the java will
read it.
client code:
~~~
public class button3 extends Activity{
WebView wb = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.buttons);
wb = new WebView(this);
wb.setWebViewClient(new HelloWebViewClient());
wb.getSettings().setJavaScriptEnabled(true);
wb.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT");
/* WebViewClient must be set BEFORE calling loadUrl! */
wb.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url)
{
/* This call inject JavaScript into the page which just
finished loading. */
wb.loadUrl("javascript:window.HTMLOUT.showHTML(document.getElementsByTagName('html').innerHTML);");
}
});
wb.loadUrl("http://www.whateverurl.com";);
setContentView(wb);
}
private class HelloWebViewClient extends WebViewClient {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
final Context myApp = this;
class MyJavaScriptInterface
{
public void showHTML(String html)
{
new AlertDialog.Builder(myApp)
.setTitle("Value of Hidden ID")
.setMessage(html)
.setPositiveButton(android.R.string.ok, null)
.setCancelable(false)
.create()
.show();
}
}
~~~
html code:
~~~
Lunch<br><img src='http://www.?????/mimages/image002.jpg'
style="width: 300px;" ><br><p><input type='hidden' id='sendtextcoupon'
value='0'>
Do You SEE THIS</p>
~~~
Any help would be great!
