I am creating an application in which I have to check the word typed by user is correct or not using Google dictionary. If the word typed by user is correct, then a toast will be displayed. I am not getting any proper solution on my Google search. So please give me some idea if it is possible.
#Override
public void onGetSuggestions(final SuggestionsInfo[] arg0) {
isSpellCorrect = false;
final StringBuilder sb = new StringBuilder();
for (int i = 0; i < arg0.length; ++i) {
// Returned suggestions are contained in SuggestionsInfo
final int len = arg0[i].getSuggestionsCount();
if(editText1.getText().toString().equalsIgnoreCase(arg0[i].getSuggestionAt(j))
{
isSpellCorrect = true;
break;
}
}
}
You can find the whole project from this link. In above project you can see string is appended. Instead just change the above method onGetSuggestions..

Ok so I want my app to open youtube when a button is clicked. For some reason it does not work!
this is my code:
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val btn_subscribe = findViewById<Button>(R.id.sub_button)
btn_subscribe.setOnClickListener{
btn_subscribe.text = "Subscribed"
val webIntent: Intent = Uri.parse("https://www.youtube.com").let { webpage ->
Intent(Intent.ACTION_VIEW, webpage)
}
}
}
}
I'm Java Developer so I cannot code with Kotlin but I'll show you how to open youtube from your app.
Use this method in your button ClickListner
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.youtube.com/c/AndroidDevelopers")));
Your new code looks like below
btn_subscribe.setOnClickListener{
btn_subscribe.text = "Subscribed"
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.youtube.com/c/AndroidDevelopers")));
}
}
Make sure to change JAVA to Kotlin in my code. If you any problem is causing, Let me know

Trying to select a table called Pregunta with some questions in my azure database to display it in a combobox in my application.
The code is as follow:
Method for Selecting the Pregunta Table:
public static async Task<ObservableCollection<Pregunta>> SelectQuestions()
{
try
{
return await client.GetTable<Pregunta>().ToCollectionAsync();
}
catch (MobileServiceInvalidOperationException msioe)
{
var response = await msioe.Response.Content.ReadAsStringAsync();
return null;
}
catch (Exception ex)
{
return null;
}
}
Displaying items in the Combobox:
protected override async void OnAppearing()
{
base.OnAppearing();
ObservableCollection<Pregunta> questions = await Pregunta.SelectQuestions();
PreguntaEntry.DataSource = questions;
}
I got no errors, but it retrives nothing, the question variable value is null when trying to display it.
I will appreciate any help as I'm new with Azure.
Solution:
Make sure that the string varibale questions in my app table model was named same as the database.
Through the Syncfusion document, I think you should use PreguntaEntry.ComboBoxSource:
protected override async void OnAppearing()
{
base.OnAppearing();
ObservableCollection<Pregunta> questions = await Pregunta.SelectQuestions();
PreguntaEntry.ComboBoxSource= questions;
}

I want to achieve the functionality of Stage.showAndWait() without using the method itself.
I have an application and I need a way of displaying something within the same stage and block the thread displaying the content until a button is pressed.
The thread displaying the content naturally needs to be tha JavaFX application thread - which of course won't handle the buttons as long as it is blocked.
Stage.showAndWait describes its inner workings as "This method temporarily blocks processing of the current event, and starts a nested event loop to handle other events." I see that the method calls "Toolkit.getToolkit().enterNestedEventLoop(this)", which is pretty implementation specific. Are there any other options? Is functionality like this exposed anywhere in the API?
Edit:
Since my question was misleading, I try to rephrase it more to the point from my current perspective:
Is there a public API for Toolkit.getToolkit().enterNestedEventLoop() and Toolkit.getToolkit().exitNestedEventLoop() ?
For my rephrased question:
Is there a public API for Toolkit.getToolkit().enterNestedEventLoop() and Toolkit.getToolkit().exitNestedEventLoop() ?
Since then the API has been made public in:
javafx.application.Platform.enterNestedEventLoop()
It isn't really clear what you are trying to do, but it sounds like you have some long running process that is building up some kind of data, and then you want the user to control how that built up data is delivered to the screen. In that case, then you need to run a background task to build the data, transfer that data to some element that is available to the FXAT, and then use the action event of a button to move the data onto the screen. Something like this:
public class LongTask extends Application {
StringProperty results = new SimpleStringProperty("");
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World!");
TextArea textArea = new TextArea();
BorderPane root = new BorderPane();
root.setCenter(textArea);
Button button = new Button("More Data");
root.setBottom(button);
button.setOnAction(evt -> textArea.setText(results.get()));
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
Task<Void> sleeper = new Task<Void>() {
#Override
protected Void call() throws Exception {
for (int iteration = 0; iteration < 1000; iteration++) {
try {
Thread.sleep(5000);
int i = iteration;
Platform.runLater(() -> results.set(results.get() + "\nIteration " + i));
} catch (InterruptedException e) {
}
}
return null;
}
};
new Thread(sleeper).start();
}
}
Technically, you don't need to make "results" a property, nor do you need to update it through Platform.runlater(). Using Platform.runlater() guarantees that you won't have concurrency issues with results. Also, if you bind "results" to anything, then you'll need to use Platform.runlater() to modify it.
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center.

I need to get a callback with every character typed or deleted in EditField in BlackBerry. I need to get the text of EditField as soon as it is written, without losing focus.
There's multiple ways to do this. For example, if you have an EditField instance like this:
private EditField _editField;
then you can subclass EditField and override the keyChar() method:
_editField = new EditField() {
protected boolean keyChar(char key, int status, int time) {
super.keyChar(key, status, time);
// 'key' is the most recent entered char
}
});
or, you can implement a FieldChangeListener and listen for changes:
_editField.setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
String text = _editField.getText();
// 'text' is the full text contents of the EditField
}
});

How to get the URL of current page in JSF?

How can I get a complete URI address ( http:// .../ ../.) in JSF using FacesContext ?
Should be something like this:
public String getRequestUrl()
{
Object request = FacesContext.getCurrentInstance().getExternalContext().getRequest();
if (request instanceof HttpServletRequest)
{
String requestedUrl = ((HttpServletRequest) request).getRequestURL().toString();
return requestedUrl;
}
return "";
}
