从网络视图重定向到新 activity

Question

在此应用程序中，我正在尝试创建一个登录页面 "Main activity 1" 以显示 login/registration 网站。然后只有在用户成功登录后我才想显示第二个 activity 。我知道我可以使用解析来创建一个 SQL 数据库，但在这种情况下我想避免这种情况并使用我的网站来处理注册/登录数据库 ("tell me based on your experience if it is a stupid idea ").

public class MainActivity extends AppCompatActivity {
//move to second activity only afther login 
WebView webView;
public class webView() {
    if (webView.loadUrl("login URL")!= webView.loadUrl("login URL")){ //need help here
        Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
        startActivity(intent);
    }
    return ;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // DISPALY WEBSITE FOR LOGIN
    webView = findViewById(R.id.webview);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.setWebViewClient(new WebViewClient());
    webView.loadUrl("login URL");
}

}

您可以添加 webview 侦听器并可以在用户登录时触发新的 activity，您可以通过以下代码。

webview.setWebViewClient(new WebViewClient()
    {
        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);

            //Here check whether the url is after logged in
            if(url.equals("URL after user logged In")){
                //start new activity
          }

        }

        @Override
        public void onPageFinished(WebView view, String url) {
            Log.d("WebView", "your current url when webpage loading.. finish" + url);
            super.onPageFinished(view, url);
        }

        @Override
        public void onLoadResource(WebView view, String url) {
            // TODO Auto-generated method stub
            super.onLoadResource(view, url);
        }
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            System.out.println("when you click on any interlink on webview that time you got url :-" + url);
            return super.shouldOverrideUrlLoading(view, url);
        }
    });

希望对您有所帮助。
