I insert an image object in my code,the program could run,but the image doesn't show.

Image path is correct? Check this pic.

CodePudding user response：

Your code generally works, so the problem is most likely an issue with the image.

You should inspect the errorProperty and exceptionProperty, for example...

if (image.errorProperty().getValue()) {
    image.exceptionProperty().getValue().printStackTrace();
}

Runnable example...

import java.io.File;
import javafx.application.Application;
import static javafx.application.Application.launch;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Pane;
import javafx.stage.Stage;

public class App extends Application {

    @Override
    public void start(Stage stage) {
        Pane pane = new HBox(10);
        pane.setPadding(new Insets(5, 5, 5, 5));

        Image image = new Image(new File("image/v2-7c37a26d9dd77abf6de2ca9ca3fc7ae0_720w.jpg").toURI().toString());//remember this must be an url address,
        if (image.errorProperty().getValue()) {
            image.exceptionProperty().getValue().printStackTrace();
        }

        pane.getChildren().add(new ImageView(image));

        ImageView imageView2 = new ImageView(image);
        imageView2.setFitHeight(100);
        imageView2.setFitWidth(100);
        pane.getChildren().add(imageView2);

        ImageView imageView3 = new ImageView(image);
        imageView3.setRotate(90);
        pane.getChildren().add(imageView3);

        Scene scene = new Scene(pane);
        stage.setScene(scene);
        stage.sizeToScene();
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }
}
