我有一个.fxml文件,里面有一些空矩形
<AnchorPane id="AnchorPane" prefHeight="700.0" prefWidth="650.0" styleClass="fondo2" stylesheets="@tablerolote.css" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="juegoloto.CartonController">
<children>
<GridPane gridLinesVisible="true" layoutX="11.0" layoutY="44.0" prefHeight="614.0" prefWidth="474.0" styleClass="fondo">
<columnConstraints>
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
</columnConstraints>
<rowConstraints>
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
</rowConstraints>
<children>
<ImageView id="1" fitHeight="127.0" fitWidth="93.0" pickOnBounds="true" preserveRatio="true" />
<ImageView id="2" fitHeight="127.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="1" />
<ImageView id="3" fitHeight="126.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="2" />
<ImageView id="4" fitHeight="127.0" fitWidth="97.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="3" />
</children>
</GridPane>
</children>
</AnchorPane>
它是使用netbeans(拖放界面)自动创建的,我如何发送和图像显示在ImageView id="2" /ImageView id="3"
等。来自.java文件
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("Carton.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
我也有一个controller.java文件,但我不知道该怎么做
public class CartonController implements Initializable {
@FXML
private Label label;
@FXML
@Override
public void initialize(URL url, ResourceBundle rb) {
// TODO
}
}

您应该在控制器类中执行此操作。 FXML reference中详细描述了如何使用控制器,但简而言之:
在fx:id
上添加ImageView
(您可以在SceneBuilder中执行此操作):
<AnchorPane id="AnchorPane" prefHeight="700.0" prefWidth="650.0" styleClass="fondo2" stylesheets="@tablerolote.css" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1" fx:controller="juegoloto.CartonController">
<children>
<GridPane gridLinesVisible="true" layoutX="11.0" layoutY="44.0" prefHeight="614.0" prefWidth="474.0" styleClass="fondo">
<columnConstraints>
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
<ColumnConstraints hgrow="SOMETIMES" minWidth="10.0" prefWidth="100.0" />
</columnConstraints>
<rowConstraints>
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
<RowConstraints minHeight="10.0" prefHeight="30.0" vgrow="SOMETIMES" />
</rowConstraints>
<children>
<ImageView id="1" fx:id="imageView1" fitHeight="127.0" fitWidth="93.0" pickOnBounds="true" preserveRatio="true" />
<ImageView id="2" fx:id="imageView2" fitHeight="127.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="1" />
<ImageView id="3" fx:id="imageView3" fitHeight="126.0" fitWidth="96.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="2" />
<ImageView id="4" fx:id="imageView4" fitHeight="127.0" fitWidth="97.0" pickOnBounds="true" preserveRatio="true" GridPane.columnIndex="3" />
</children>
</GridPane>
</children>
</AnchorPane>
然后将它们注入您的控制器,您可以根据需要访问它们:
public class CartonController implements Initializable {
@FXML
private ImageView imageView1 ;
@FXML
private ImageView imageView2 ;
@FXML
private ImageView imageView3 ;
@FXML
private ImageView imageView4 ;
@Override
public void initialize(URL url, ResourceBundle rb) {
imageView1.setImage(new Image(...));
// etc...
}
}

您可以定义检索ImageView
的方法:
public ImageView findById(AnchorPane root, String id) {
for (Node child : root.getChildren()) {
if (child instanceof ImageView && child.getId().equals(id)) {
return (ImageView)child;
}
}
return null;
}
此方法将遍历根AnchorPane
的所有直接子节点,并检查ImageView
节点的ID。如果未找到匹配的节点,则返回null。从那里,您可以在返回的setImage
上使用ImageView
方法。
