        android:layout_height="match_parent"
        android:orientation="horizontal" >

        <WebView
            android:id="@+id/webView1"
            android:layout_width="350dp"
            android:layout_height="match_parent"

            android:layout_alignParentLeft="true" />


        <WebView
            android:id="@+id/webView22"
            android:layout_width="350dp"
            android:layout_height="match_parent"

</HorizontalScrollView>

and this is a part of my main.java

webView = (WebView) findViewById(R.id.webView1);
    String url = "http://google.com";
    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl(url);
    webView.setWebChromeClient(new WebChromeClient()); 
    webView.setWebViewClient(new WebViewClient());





    WebView webView22 = (WebView)findViewById(R.id.webView22);
    webView22.getSettings().setJavaScriptEnabled(true);
    webView22.loadUrl("google.com);
    webView22.setWebChromeClient(new WebChromeClient()); 
    webView22.setWebViewClient(new WebViewClient());
