How to get the content height of each page in android with or without javaScript?

I want to get the content height of each webpage one by one. But I am not getting that. If I am loading page separately then I am able to get the height of each page. But if I tried to get content height of webpage continuously then I failed.

Here is my code-

StringBuffer content;
     String temp;

         for(i=tempstart_index;i<=tempend_index;i++)
                {
                Log.i("value of i",i+1+"");

                content+=decrypted(i);
                temp1=decrypted(i);
                // TODO Auto-generated method stub
                webview.setWebViewClient(new WebClient());
                {

                    @Override
                    public void onPageFinished(WebView view, String url)
                    {
                        webview.loadUrl("javascript:window.HTMLOUT.getContentHeight(document.getElementsByTagName('html')[0].scrollHeight);");
                        int initialpageheight=webview.getContentHeight();

                        if(initialpageheight>0)
                        {
                            webheight=initialpageheight;

                            //Toast.makeText(getApplicationContext(), ""+initialpageheight, Toast.LENGTH_LONG).show();
                            Log.i("page finish","" +webheight);

                            initialpage=webheight;
                            if(pagenumber>0)
                            {
                            webview.scrollTo(0, webheight);
                            }
                                         }
         }});
         webview.loadDataWithBaseURL("file:///android_asset/KH_Brown_Fixed_Layout/",temp1,
     "text/html", "utf-8",null);
                }
         return content;
         }

then I am displaying the all merged page as a one page after merging string-

//here reflowable() reading html and merging them and after merging returning it.

 String ds=reflowable();
                webview.loadDataWithBaseURL("file:///android_asset/KH_Brown_Fixed_Layout/", ds, "text/html", "utf-8", null);

In JavaScript you can get the height of the page on a webkit browser with:

window.innerHeight

As to what else you're attempting in there, I have no clue, but that'll give you the height in your Android browser.
