I have a JavaFX WebView and want to call the method "hello" of the class "JavaBridge" from "test.html" displayed in the webview.
Why doesn't this work? I making sure that the "bridge" object only be added to the window.object when the page has been fully rendered, so that is probably not the problem. I can't see any problem with the HTML either.
Here is the HTML code ("test.html"):
<html>
<head>
</head>
<body>
call java
</body>
</html>
And here is the Java Code:
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.concurrent.Worker;
import javafx.concurrent.Worker.State;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;
import netscape.javascript.JSObject;
public class HelloWorld extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
java.net.URI uri = java.nio.file.Paths.get("test.html").toAbsolutePath().toUri();
WebView root = new javafx.scene.web.WebView();
root.getEngine().load(uri.toString());
root.getEngine().
getLoadWorker().
stateProperty().
addListener(new ChangeListener < State > () {
#Override public void changed(ObservableValue ov, State oldState, State newState) {
if (newState == Worker.State.SUCCEEDED) {
System.out.println("READY");
JSObject jsobj = (JSObject) root.getEngine().executeScript("window");
jsobj.setMember("bridge", new JavaBridge());
}
}
});
primaryStage.setScene(new javafx.scene.Scene(root, 800, 600));
primaryStage.show();
}
}
class JavaBridge {
public void hello() {
System.out.println("hello");
}
}
When using this bridge feature on Java 10.0.2, I noticed that it was not working consistently. Javascript upcalls wasn't working all the times.
After researching, I found out this OpenJDK bug related to Java Garbage Collector, which seems to happen on regular JDK as well:
https://bugs.openjdk.java.net/browse/JDK-8170085
Indeed, according to https://docs.oracle.com/javase/9/docs/api/javafx/scene/web/WebEngine.html, it's recommended to store the bridge into a variable to avoid Java GC to collect the object.
After adding a private variable to the class, the JS to Java calls started to work all the time in my Application.
Your inner class should be inside the main class. And it should be public. Like this:
import java.net.URL;
import javafx.application.Application;
import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.concurrent.Worker;
import javafx.concurrent.Worker.State;
import javafx.scene.web.WebView;
import javafx.stage.Stage;
import netscape.javascript.JSObject;
public class HelloWorld extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
final URL url = getClass().getResource("test.html");
WebView root = new javafx.scene.web.WebView();
root.getEngine().load(url.toExternalForm());
root.getEngine().getLoadWorker().stateProperty().addListener(new ChangeListener<State>() {
#Override
public void changed(ObservableValue ov, State oldState, State newState) {
if (newState == Worker.State.SUCCEEDED) {
System.out.println("READY");
JSObject jsobj = (JSObject) root.getEngine().executeScript("window");
jsobj.setMember("bridge", new JavaBridge());
}
}
});
primaryStage.setScene(new javafx.scene.Scene(root, 800, 600));
primaryStage.show();
}
public class JavaBridge {
public void hello() {
System.out.println("hello");
}
}
}
I had the same problem and the only way to fix it was storing the Bridge on a static variable.
this is an example to use the javafx FileChooser.
public class Controller implements Initializable {
#FXML private WebView webview;
#FXML private JFXButton btn_insertimg;
#FXML private AnchorPane anchorpane;
private WebEngine webEngine;
public static Bridge bridge; //it's important to be static
#Override
public void initialize(URL location, ResourceBundle resources) {
webEngine = webview.getEngine();
webEngine.getLoadWorker().stateProperty().addListener(
(ov, oldState, newState) -> {
if (newState == Worker.State.SUCCEEDED) {
//todo when the document is fully loaded
FileChooser fileChooser=new FileChooser();
bridge=new Bridge(webview,fileChooser);
JSObject window = (JSObject) webEngine.executeScript("window");
window.setMember("myFileChooser", bridge);
System.out.println("member "+window.getMember("myFileChooser").toString());;
}//end of SUCCEEDED state
});
webEngine.load(getClass().getResource("/patient/texteditor/summernote.html").toExternalForm());
}
public class Bridge{
FileChooser fileChooser;
WebView webView;
Bridge(WebView webView,FileChooser fileChooser){
this.webView=webView;
this.fileChooser=fileChooser;
}
public void display(){
fileChooser.showOpenDialog(webView.getScene().getWindow());
}
}
}

I'm following a guide on coding by Easy Tuto, currently on part 7 at the end where the recycler_note_item.xml would show up on the interface. In the video, he fixed the problem by adding the onStart, onStop, onResume commands and adding `noteAdapter.startListening' in between the lines as shown here: image In the video, it worked and showed the item however nothing showed up for me as can be seen here . I tried scouring the video trying to find what I did wrong. I'm pretty new to coding and I was using his video as a base to learn more about it. I added those lines myself but it diddn't work for me it seems. Can someone please help me? It would be greatly appreciated. Here is my code for MainActivity.Java:
package com.example.myapplication;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ImageButton;
import com.firebase.ui.firestore.FirestoreRecyclerOptions;
import com.google.android.material.floatingactionbutton.FloatingActionButton;
import com.google.firebase.firestore.Query;
public class MainActivity extends AppCompatActivity {
FloatingActionButton addNoteBtn;
RecyclerView recyclerView;
ImageButton menuBtn;
NoteAdapter noteAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addNoteBtn = findViewById(R.id.add_note_btn);
recyclerView = findViewById(R.id.recyler_view);
menuBtn = findViewById(R.id.menu_btn);
addNoteBtn.setOnClickListener((v)-> startActivity(new Intent(MainActivity.this,NoteDetailsActivity.class)) );
menuBtn.setOnClickListener((v)->showMenu());
setupRecyclerView();
}
void showMenu(){
//TODO Display menu
}
void setupRecyclerView(){
Query query = Utility.getCollectionReferenceForNotes().orderBy("timestamp",Query.Direction.DESCENDING);
FirestoreRecyclerOptions<Note> options = new FirestoreRecyclerOptions.Builder<Note>()
.setQuery(query,Note.class).build();
recyclerView.setLayoutManager(new LinearLayoutManager(this));
noteAdapter = new NoteAdapter(options,this);
recyclerView.setAdapter(noteAdapter);
}
#Override
protected void onStart() {
super.onStart();
noteAdapter.startListening();
}
#Override
protected void onStop() {
super.onStop();
noteAdapter.stopListening();
}
#Override
protected void onResume() {
super.onResume();
noteAdapter.notifyDataSetChanged();
}
}
I think the other relevant codes is my NoteAdapter which is this:
package com.example.myapplication;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import com.firebase.ui.firestore.FirestoreRecyclerAdapter;
import com.firebase.ui.firestore.FirestoreRecyclerOptions;
import io.grpc.okhttp.internal.Util;
public class NoteAdapter extends FirestoreRecyclerAdapter<Note, NoteAdapter.NoteViewHolder>{
Context context;
public NoteAdapter(#NonNull FirestoreRecyclerOptions<Note> options, Context context) {
super(options);
this.context = context;
}
#Override
protected void onBindViewHolder(#NonNull NoteViewHolder holder, int position, #NonNull Note note) {
holder.titleTextView.setText(note.title);
holder.contentTextView.setText(note.content);
holder.timestampTextView.setText(Utility.timestamptoString(note.timeStamp));
}
#NonNull
#Override
public NoteViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.recycler_note_item,parent,true);
return new NoteViewHolder(view);
}
class NoteViewHolder extends RecyclerView.ViewHolder{
TextView titleTextView,contentTextView,timestampTextView;
public NoteViewHolder(#NonNull View itemView) {
super(itemView);
titleTextView = itemView.findViewById(R.id.note_title_text_view);
contentTextView = itemView.findViewById(R.id.note_content_text_view);
timestampTextView = itemView.findViewById(R.id.note_timestamp_text_view);
}
}
}
Please tell me if there are any other relevant codes I can give to help give more context on my problem. Thanks for helping me out if anyone!

Please help me in getting an image in the image view. Thank you in advance.
Check
of the UImage is a valid path, normally I would do something like this..
P.S Not a RecyclerView but you get the idea
imageview1 = (ImageView) findViewById(R.id.imageview1);
_path_child_listener = new ChildEventListener() {
#Override
public void onChildAdded(DataSnapshot _param1, String _param2) {
GenericTypeIndicator<HashMap<String, Object>> _ind = new GenericTypeIndicator<HashMap<String, Object>>() {};
final String _childKey = _param1.getKey();
final HashMap<String, Object> _childValue = _param1.getValue(_ind);
Glide.with(getApplicationContext()).load(Uri.parse(_childValue.get("imageUrl").toString())).into(imageview1);
//imageUrl is pushed to Firebase Storage onUploadCompleted
}
#Override
public void onChildChanged(DataSnapshot _param1, String _param2) {
GenericTypeIndicator<HashMap<String, Object>> _ind = new GenericTypeIndicator<HashMap<String, Object>>() {};
final String _childKey = _param1.getKey();
final HashMap<String, Object> _childValue = _param1.getValue(_ind);
}
#Override
public void onChildMoved(DataSnapshot _param1, String _param2) {
}
#Override
public void onChildRemoved(DataSnapshot _param1) {
GenericTypeIndicator<HashMap<String, Object>> _ind = new GenericTypeIndicator<HashMap<String, Object>>() {};
final String _childKey = _param1.getKey();
final HashMap<String, Object> _childValue = _param1.getValue(_ind);
}
#Override
public void onCancelled(DatabaseError _param1) {
final int _errorCode = _param1.getCode();
final String _errorMessage = _param1.getMessage();
}
};
path.addChildEventListener(_path_child_listener);
}
private void initializeLogic() {
}
I got this (https://stackoverflow.com/a/42040344/3789572) solution, which code is below, but it isn't working. When I press the button, nothing is shown.
You can change the file paths and try it for yourself.
Can you help me?

How do I make the white screen not appear? This is happening on Android.
As a solution for the white screen add a splash screen.

super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
Intent intent = getIntent();
hashMap = (HashMap<String,String>) intent.getSerializableExtra("hashMap");
WebView webView = (WebView) findViewById(R.id.webviewe);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl(url,hashMap);
}
}
Is there any way that I can view that webpage without logging in again to the webview?
Haven't tested it, but using CookieManager ahould work.
Usage should be something like this:
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie(); //optional
cookieManager.setAcceptCookie(true);
Then loop over your cookies using the setCookie method.
Note: If useing lollipop and up you should also use setAcceptThirdPartyCookies.
Good luck.
