Here I am writing code to load url on WebView.
We need to create WebView client where we get the event of page finished.

    WebView myWebView ; 
myWebView = (WebView)findViewbyId(R.id.my_web_view);

    myWebView.setWebViewClient(new WebViewClient() {       
        ProgressDialog  mProgressDialog; 

            public boolean shouldOverrideUrlLoading(WebView view, String url) {               
            view.loadUrl(url); 
            return true; 
        } 

        //Show loader on url load 
        public void onLoadResource (WebView view, String url) { 
            if (mProgressDialog == null) { 
                          mProgressDialog = new ProgressDialog(MyActivity.this); 
                mProgressDialog.setMessage("Loading..."); 
                mProgressDialog.show(); 
            } 
        } 
        public void onPageFinished(WebView view, String url) { 

try{ 
                if (mProgressDialog.isShowing()) { 
                    mProgressDialog.dismiss(); 
                    mProgressDialog = null; 
                } 
                }catch(Exception e){ 
                    e.printStackTrace(); 
                } 
            } 

    });  

     // Javascript inabled on webview   
    webView.getSettings().setJavaScriptEnabled(true);  


    //Load url in webview 
    webView.loadUrl(url); 


}
