Как получить HTML -контент из WebView? ⇐ Android

[Anonymous]

Какой самый простой метод получения HTML -кода из WebView? Пожалуйста, упомяните точный способ. < /P>

public class htmldecoder extends Activity implements OnClickListener,TextWatcher
{
TextView txturl;
Button btgo;
WebView wvbrowser;
TextView txtcode;
ImageButton btcode;
LinearLayout llayout;
int flagbtcode;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.htmldecoder);

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

btgo=(Button)findViewById(R.id.btgo);
btgo.setOnClickListener(this);

wvbrowser=(WebView)findViewById(R.id.wvbrowser);
wvbrowser.setWebViewClient(new HelloWebViewClient());
wvbrowser.getSettings().setJavaScriptEnabled(true);
wvbrowser.getSettings().setPluginsEnabled(true);
wvbrowser.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
wvbrowser.addJavascriptInterface(new MyJavaScriptInterface(),"HTMLOUT");
//wvbrowser.loadUrl("http://www.google.com");
wvbrowser.loadUrl("javascript:window.HTMLOUT.showHTML(''+document.getElementsByTagName('html')[0].innerHTML+'');");

txtcode=(TextView)findViewById(R.id.txtcode);
txtcode.addTextChangedListener(this);

btcode=(ImageButton)findViewById(R.id.btcode);
btcode.setOnClickListener(this);

}

public void onClick(View v)
{
if(btgo==v)
{
String url=txturl.getText().toString();
if(!txturl.getText().toString().contains("http://"))
{
url="http://"+url;
}
wvbrowser.loadUrl(url);
//wvbrowser.loadData("","text/html","utf-8");
}
else if(btcode==v)
{
ViewGroup.LayoutParams params1=wvbrowser.getLayoutParams();
ViewGroup.LayoutParams params2=txtcode.getLayoutParams();
if(flagbtcode==1)
{
params1.height=200;
params2.height=220;
flagbtcode=0;
//txtcode.setText(wvbrowser.getContentDescription());
}
else
{
params1.height=420;
params2.height=0;
flagbtcode=1;
}
wvbrowser.setLayoutParams(params1);
txtcode.setLayoutParams(params2);

}
}

public class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url);
return true;
}
/*@Override
public void onPageFinished(WebView view, String url)
{
// This call inject JavaScript into the page which just finished loading.
wvbrowser.loadUrl("javascript:window.HTMLOUT.processHTML(''+document.getElementsByTagName('html')[0].innerHTML+'');");
}*/

}
class MyJavaScriptInterface
{
@SuppressWarnings("unused")
public void showHTML(String html)
{

txtcode.setText(html);
}
}

public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub

}

public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub

}

public void onTextChanged(CharSequence s, int start, int before, int count) {
wvbrowser.loadData("","text/html","utf-8");

}

}
