JavaFX: File Chooser

JavaFx:How to choose single file and multiple files in Java Fx and display in a list view?

For creating a file chooser you should have a structure as provided below in JavaFx project.

We have created this file chooser to select single or multiple files from a specific directory and display the file names in  a list view. You may pass the directory of the file or name of the file to a Java class.

Main.java

package application;

import javafx.application.Application;

import javafx.fxml.FXMLLoader;

import javafx.stage.Stage;

import javafx.scene.Parent;

import javafx.scene.Scene;

public class Main extends Application {

@Override

public void start(Stage primaryStage) {

try {

Parent root=FXMLLoader.load(getClass().getResource("/application/Main.fxml"));

Scene scene = new Scene(root,400,400);

scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());

primaryStage.setScene(scene);

primaryStage.show();

} catch(Exception e) {

e.printStackTrace();

}

}

public static void main(String[] args) {

launch(args);

}

}

MainController.java

package application;

import java.io.File;

import java.util.List;

import javafx.event.ActionEvent;

import javafx.fxml.FXML;

import javafx.scene.control.Button;

import javafx.scene.control.ListView;

import javafx.stage.FileChooser;

import javafx.stage.FileChooser.ExtensionFilter;

public class MainController  {

@FXML

private Button btn1;

@FXML

private Button btn2;

@FXML

private ListView listview;

public void buttonaction1(ActionEvent event){

FileChooser fc =new FileChooser();

//Open files of a default directory

fc.setInitialDirectory(new File("C:\\Users\\sridhar mohanty\\Desktop"));

//Filter out a specific format

fc.getExtensionFilters().addAll(new ExtensionFilter("Microsoft Word Files","*.doc"));

File SelectedFile=fc.showOpenDialog(null);

if(SelectedFile!=null){

listview.getItems().add(SelectedFile.getName());

//Display absolute path

//listview.getItems().add(SelectedFile.getAbsolutePath());

}else{

System.out.println("File is not valid");

}

}

public void buttonaction2(ActionEvent event){

FileChooser fc =new FileChooser();

//Open files of a default directory

fc.setInitialDirectory(new File("C:\\Users\\sridhar mohanty\\Desktop"));

//Filter out a specific format

fc.getExtensionFilters().addAll(new ExtensionFilter("Microsoft Word Files","*.doc"));

List<File> SelectedFiles=fc.showOpenMultipleDialog(null);

if(SelectedFiles!=null){

for(int i=0;i<SelectedFiles.size();i++)

listview.getItems().add(SelectedFiles.get(i).getName());

}else{

System.out.println("File is not valid");

}

}

}

Main.fxml

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

<?import javafx.scene.control.Button?>

<?import javafx.scene.control.ListView?>

<?import javafx.scene.layout.AnchorPane?>

<AnchorPane prefHeight="400.0" prefWidth="400.0" xmlns="http://javafx.com/javafx/8.0.65" xmlns:fx="http://javafx.com/fxml/1" fx:controller="application.MainController">
