    Hello friend's
    If you are looking to created WebView function in android below example will help you. WebView is used for display web pages inside your application and it turns application to a web application.
    Here I have added <webview> element to xml layout file and using loadUrl(String url) method of the webView class, specifying the required url. See the below example code it will clearly described you how to create WebView function.</webview>

    Step(1)-MainActivity Class-

    public class MainActivity extends Activity  {
       Button b1;
       EditText ed1;
    
       private WebView wv1;
       @Override
       protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
    
          b1=(Button)findViewById(R.id.button);
          ed1=(EditText)findViewById(R.id.editText);
    
          wv1=(WebView)findViewById(R.id.webView);
          wv1.setWebViewClient(new MyBrowser());
    
          b1.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                String url = ed1.getText().toString();
    
                wv1.getSettings().setLoadsImagesAutomatically(true);
                wv1.getSettings().setJavaScriptEnabled(true);
                wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
                wv1.loadUrl(url);
             }
          });
       }
    
       private class MyBrowser extends WebViewClient {
          @Override
          public boolean shouldOverrideUrlLoading(WebView view, String url) {
             view.loadUrl(url);
             return true;
          }
       }
    
       @Override
       public boolean onCreateOptionsMenu(Menu menu) {
          getMenuInflater().inflate(R.menu.menu_main, menu);
          return true;
       }
    
       @Override
       public boolean onOptionsItemSelected(MenuItem item) {
          int id = item.getItemId();
    
          if (id == R.id.action_settings) {
             return true;
          }
          return super.onOptionsItemSelected(item);
       }
    }
    

    Step(2)-main.xml layout-

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
        android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">
    
        <TextView 
             android:text="WebView"
           android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/textview"
            android:textSize="35dp"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true" />
    
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Web View Evon-tech"
            android:id="@+id/textView"
            android:layout_below="@+id/textview"
            android:layout_centerHorizontal="true"
            android:textColor="#ff7aff24"
            android:textSize="35dp" />
    
        <EditText
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/editText"
            android:hint="Enter Text"
            android:focusable="true"
            android:textColorHighlight="#ff7eff15"
            android:textColorHint="#ffff25e6"
            android:layout_marginTop="46dp"
            android:layout_below="@+id/imageView"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_alignRight="@+id/imageView"
            android:layout_alignEnd="@+id/imageView" />
    
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/imageView"
            android:src="@drawable/img"
            android:layout_below="@+id/textView"
            android:layout_centerHorizontal="true" />
    
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Enter"
            android:id="@+id/button"
            android:layout_alignTop="@+id/editText"
            android:layout_toRightOf="@+id/imageView"
            android:layout_toEndOf="@+id/imageView" />
    
        <WebView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/webView"
            android:layout_below="@+id/button"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_alignParentRight="true"
            android:layout_alignParentEnd="true"
            android:layout_alignParentBottom="true" />
    
    </RelativeLayout>
