单击基于 Firebase 的推送通知时，在 WebView 中打开特定 URL 页面？

Question

单击基于 Fire base 的推送通知时在 WebView 中打开特定 URL 页面？

我使用Webview创建了一个Android应用程序并实现了Firebase推送通知，我还在发送推送通知时在firebase消息控制台中的自定义数据字段中传递了URL，但是当我单击通知时，它直接打开我的应用程序的主页。如何让它在点击通知时打开应用程序中的特定页面？

我使用了以下代码，但它仍然打开一个开放页面而不是特定页面。请推荐

这是我的代码

主要活动

`公共类 MainActivity 扩展 AppCompatActivity {

private WebView mywebView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mywebView=(WebView) findViewById(R.id.webview);
    mywebView.setWebViewClient(new WebViewClient());
    mywebView.loadUrl("https://exampe.blogspot.com/");
    WebSettings webSettings=mywebView.getSettings();
    webSettings.setJavaScriptEnabled(true);


}`

MyFirebaseMessagingService 类

公共类 MyFirebaseMessagingService 扩展 FirebaseMessagingService {

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);

    // Extract the URL from the notification data
    String url = remoteMessage.getData().get("url");

    // Create a PendingIntent to open the URL in the webview
    Intent intent = new Intent(this, MainActivity.class);
    intent.putExtra("url", url);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    // Build and show the notification
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, "default_channel")
            .setContentTitle(remoteMessage.getNotification().getTitle())
            .setContentText(remoteMessage.getNotification().getBody())
            .setSmallIcon(R.mipmap.ic_launcher)
            .setContentIntent(pendingIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(0, notificationBuilder.build());
}

}

您需要从

Intent

获取您从

PendingIntent

传递的URL，如下所示

public class MainActivity extends AppCompatActivity {

private WebView mywebView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mywebView=(WebView) findViewById(R.id.webview);

    String url = getIntent.getStringExtra("url");

    mywebView.setWebViewClient(new WebViewClient());
    mywebView.loadUrl(url);

    WebSettings webSettings=mywebView.getSettings();
    webSettings.setJavaScriptEnabled(true);

}
