Step 6:webView_xml & java

<?xml version="1.0" encoding="utf-8"?>

        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentBottom="true" />


</RelativeLayout>


Step 6:web.java

package demoproject.aalap.com.web;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
import android.widget.EditText;

public class webview extends AppCompatActivity {
  //  Button b1;
    //EditText ed1;
    private WebView wv1;
    String url;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);

        String data = getIntent().getExtras().getString("web");


       // b1=(Button)findViewById(R.id.button);
        //ed1=(EditText)findViewById(R.id.editText);

        wv1=(WebView)findViewById(R.id.webView);
        wv1.setWebViewClient(new MyBrowser());

        wv1.getSettings().setLoadsImagesAutomatically(true);
        wv1.getSettings().setJavaScriptEnabled(true);
        wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
        wv1.loadUrl(data);
    }

    private class MyBrowser extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);
            return true;
        }
    }
