从 FirebaseMessagingService 重新加载 Web 视图

Question

我想重新加载我的Web视图，当收到通知并点击通知时，它会在我的MainActivity中从FirebaseMessagingService。

这是我到目前为止的代码。

FirebaseMessagingService.javainonMessageReceived方法我有

if(MainActivity.isAppRunning){
Delegate.theMainActivity.onNotificationRefresh();
}

委托.java

package ###@@##@@;
public class Delegate {
static MainActivity theMainActivity;
}

在我的主活动中，有我试图调用的这种方法

public void onNotificationRefresh() {
webView.loadUrl("www.google.com");
}

现在，当每个我收到通知而不是调用重新加载应用程序崩溃时。

试试这样，你可以使用BroadcastReceiver

示例代码

public class MyFirebaseMessagingService extends FirebaseMessagingService {

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Log.e("NOTIFICATION_DATA", remoteMessage.getData() + "");
Intent new_intent = new Intent();
Bundle bundle = new Bundle();// use bundle if you want to pass data
bundle.putString("msgBody", remoteMessage.getData().toString());
new_intent.putExtra("msg", bundle);
new_intent.setAction("ACTION_ACTIVITY");
sendBroadcast(new_intent);      

}
}

比像这样在您的活动中使用

public class MyActivity extends AppCompatActivity {
WebView webView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);

}
@Override
protected void onResume() {
super.onResume();
// registering BroadcastReceiver
if (activityReceiver != null) {
IntentFilter intentFilter = new IntentFilter("ACTION_ACTIVITY");
registerReceiver(activityReceiver, intentFilter);
}
}
@Override
protected void onPause() {
super.onPause();
LocalBroadcastManager.getInstance(this).unregisterReceiver(activityReceiver);
}
private BroadcastReceiver activityReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// reload your webview here
webView.loadUrl("https://stackoverflow.com/users/7666442/nilesh-rathod?tab=profile");
}
};
}
