如何在同一Webview应用程序中打开两个不同的URL

Question

我正在开发一款Android电子商务应用程序，使用Webview将响应式网站调用到移动应用程序中，每个功能都可以正常工作，但是当我点击PAYONLINE时，它会在浏览器中打开支付网关页面。如何隐藏该浏览器并在同一应用程序中打开支付网关页面？

假设您在印度。我已经使用了您的代码来复现问题。它在外部浏览器中加载google.co.in。 - Ganesh Kanna

是的，我来自印度。 - Prashant Das

String host = Uri.parse(url).getHost(); 如果(host.contains("www.google.co.in")) { return false; } - Ganesh Kanna

使用 contains 代替 ends with - Ganesh Kanna

请检查这个

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 {
