import android.webkit.WebViewClient;

  

public class MainActivity extends AppCompatActivity {

  

     @Override

     protected void onCreate(Bundle savedInstanceState) {

         super.onCreate(savedInstanceState);

           

         // Binding MainActivity.java with 

         // activity_main.xml file

         setContentView(R.layout.activity_main);

           

         // Find the WebView by its unique ID

         WebView w = (WebView) findViewById(R.id.web);

          

        // loading http://www.google.com url in the the WebView.

         w.loadUrl("http://www.google.com");

           

         // this will enable the javascipt.

         w.getSettings().setJavaScriptEnabled(true);

           

         // WebViewClient allows you to handle 

         // onPageFinished and override Url loading.

         w.setWebViewClient(new WebViewClient());

<RelativeLayout

     xmlns:android="http://schemas.android.com/apk/res/android"

     xmlns:tools="http://schemas.android.com/tools"

     xmlns:app="http://schemas.android.com/apk/res-auto"

     android:layout_width="match_parent"

     android:layout_height="match_parent"

     tools:context="com.example.hp.webview.MainActivity">

  

     <WebView

         <!-- covers 368dp width as required. -->

         android:layout_width="368dp"

          

         <!-- unique ID of WebView -->

         android:id="@+id/web"

          

         <!-- covers 495dp height as required. -->

         android:layout_height="495dp"

          

         tools:layout_editor_absoluteX="8dp"

         tools:layout_editor_absoluteY="8dp" />
