同じWebviewアプリケーションで2つの異なるURLを開く方法

Question

私はwebviewを使用してモバイルアプリケーションに応答するWebアプリケーションを呼び出すためのアンドロイド電子商取引アプリケーションを開発していますが、PAYONLINEをクリックすると支払いゲートウェイページブラウザに表示されます。そのブラウザを非表示にして、同じアプリケーションの支払いゲートウェイページを開く方法は？

MainActivity.java

package com.prashantlaldas; 

     import android.app.Activity; 
     import android.os.Bundle; 
     import android.view.View;

     mWebView = (WebView) findViewById(R.id.webView); 
     WebSettings webSettings = mWebView.getSettings(); 
     mWebView.getSettings().setUseWideViewPort(false); 
     webSettings.setJavaScriptEnabled(true); 
     mWebView.loadUrl("http://www.google.com/"); 



     mWebView.setWebViewClient(new MyAppWebViewClient() { 
             public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
              // mWebView.loadUrl("file:///android_asset/error.html"); 
              String data = "\n" +

ちょうどこの

public class MainActivity extends AppCompatActivity { 

    private WebView mWebView = null; 

    @Override 
    protected void onCreate(@Nullable Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 


     setContentView(R.layout.activity_main); 

     mWebView = (WebView) findViewById(R.id.webView); 
     mWebView.setVerticalScrollBarEnabled(true); 
     mWebView.setHorizontalScrollBarEnabled(true); 
     mWebView.setWebViewClient(new myWebClient()); 
     WebSettings webSettings = mWebView.getSettings(); 
     webSettings.setDomStorageEnabled(true); 
     webSettings.setJavaScriptEnabled(true); 
     webSettings.setJavaScriptCanOpenWindowsAutomatically(true); 

     // load URL here 
     mWebView.loadUrl("http://www.google.com/"); 
    } 


    /** 
    * The type My web client. 
    */ 
    public class myWebClient extends WebViewClient { 
     @Override 
     public void onPageStarted(WebView view, String url, Bitmap favicon) { 
      super.onPageStarted(view, url, favicon); 
      // page started event 
     } 

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

     @Override 
     public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) { 
      super.onReceivedError(view, errorCode, description, failingUrl); 
     } 

     @Override 
     public void onPageFinished(final WebView view, final String url) { 
      super.onPageFinished(view, url); 
      new Thread(new Runnable() { 
       @Override 
       public void run() { 
        // hide progress bar 
       } 
      }).start(); 
     } 
    } 
}
