Answer 1

use webview in different layout in  our application like this::---->


webview.xml

<?xml version="1.0" encoding="utf-8"?>
<WebView  xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/webView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
/>

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/buttonUrl"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Go to http://www.google.com" />

</LinearLayout>


mainactivity.java 

public class MainActivity extends Activity {

    private Button button;

    public void onCreate(Bundle savedInstanceState) {
        final Context context = this;

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        button = (Button) findViewById(R.id.buttonUrl);

        button.setOnClickListener(new OnClickListener() {

          @Override
          public void onClick(View arg0) {
            Intent intent = new Intent(context, WebViewActivity.class);
                    intent.putExtra("url","www.google.com")
            startActivity(intent);
          }

        });

    }

}


webviewactivity.java

public class WebViewActivity extends Activity {

    private WebView webView;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);

        webView = (WebView) findViewById(R.id.webView1);
        webView.getSettings().setJavaScriptEnabled(true);
                if (getIntent().hasExtra("url")) {
                    webView.loadUrl("http://www.google.com");
                }


    }

}
