如果通知消息中有URL,则从FCM中将Android程序中的通知消息作为链接/ URL打开

标签: android android-intent android-activity firebase-cloud-messaging android-notifications

使用FCM的PUSH通知代码在Android中将标题和消息作为通知文本发送,当我单击“文本”时,它将带我到APP首页(在APP中) 我正在通知中发送URL作为消息,以便有人单击通知“应在应用程序中打开并在应用程序中打开相应的页面(如链接中所示)

FCM推送后的通知

前任职称-气候变化影响

消息作为Ex的URL-https://example.com/dsfdsfdsfdsf(与动态URL有关)

我想在APP中打开URL,而不仅仅是在单击URL之后打开APP。请使用更新的代码

我应该做些什么改变以达到相同的目的。

基本上,您不会从接收到您的网址的MainActivity中的Intent中收到消息。

修改onCreate方法的活动

       @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    txtRegId = (TextView) findViewById(R.id.txt_reg_id);
    txtMessage = (TextView) findViewById(R.id.txt_push_message);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); // Make to run your application only in portrait mode
    //setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); // Make to run your application only in LANDSCAPE mode

    progressBar = (ProgressBar) findViewById(R.id.progressBar);
    webView = (WebView) findViewById(R.id.webView);
    textView = (TextView) findViewById(R.id.textView1212);
    webView.setWebViewClient(new MyWebViewClient());
    WebSettings browserSetting = webView.getSettings();
    browserSetting.setJavaScriptEnabled(true);
    browserSetting.setGeolocationEnabled(true);
    webView.setWebChromeClient(new WebChromeClient() {

        public void onProgressChanged(WebView view, int progress) {

            progressBar.setProgress(progress);
            textView.setText(progress + " %");
        }
    });

    mRegistrationBroadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {

            // checking for type intent filter
            if (intent.getAction().equals(Config.REGISTRATION_COMPLETE)) {
                // gcm successfully registered
                // now subscribe to `global` topic to receive app wide notifications
                FirebaseMessaging.getInstance().subscribeToTopic(Config.TOPIC_GLOBAL);
            } else if (intent.getAction().equals(Config.PUSH_NOTIFICATION)) {
                // new push notification is received

                String message = intent.getStringExtra("message");
                if (message != null) {
                    url = message;
                }
                Toast.makeText(getApplicationContext(), "Push notification: " + message, Toast.LENGTH_LONG).show();

                txtMessage.setText(message);
            }
        }
    };

    Intent intent = getIntent();
    final String yourUriThatYouWantToOpen = intent.getStringExtra("message");

    if (yourUriThatYouWantToOpen != null) {
        url = yourUriThatYouWantToOpen;
    }
    webView.loadUrl(url);
}
