      <ImageView fx:id="img1" fitHeight="32.0" fitWidth="32.0" layoutX="109.0" layoutY="126.0" pickOnBounds="true" preserveRatio="true">

         </image>
      </ImageView>
      <ProgressIndicator fx:id="progress" layoutX="197.0" layoutY="120.0" minHeight="0.0" minWidth="0.0" prefHeight="128.0" prefWidth="188.0" progress="0.0" styleClass="progressind" />

</AnchorPane>

Answer 1

The problem is because you are using AnchorPane as your root pane. Though, you can use AnchorPane for scenarios like this, I personally do not prefer it because you need to do a lot of things to get it right. There are easier ways to do and that is what I am gonna show you.

From the Javadocs :

AnchorPane allows the edges of child nodes to be anchored to an offset from the anchor pane's edges.

Solution

Use a different layout. May be a GridPane or VBox. These layouts have child alignment instead of anchors, which allow the children to be aligned to a particular position.

For re-sizing your children, you can set the HGrow / VGrow property on them.

Example

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.geometry.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>


<VBox alignment="CENTER" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" spacing="20.0" style="-fx-background-color: DARKCYAN;" xmlns="http://javafx.com/javafx/8.0.40" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <Label text="Easy Doctor" />
      <TextField promptText="Username" />
      <TextField promptText="Password" />
   </children>
   <padding>
      <Insets bottom="50.0" left="50.0" right="50.0" top="50.0" />
   </padding>
</VBox>

Here is a small gif on how it looks :

Answer 2

Please add

AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0"

to your image ,button , lable etc components speciefic size means when screen resize depend on that it will adjust its like Margin in css.

Or

you can add css to align this component as per screen size like

Scene scene = new Scene(root);
scene.getStylesheets().add(locator.locateAsURL("Css/StudentApp.css").toExternalForm());
scene.getStylesheets().add(("CSS/studentapp.css"));
