1. Introduction

The FileTree library offers a comprehensive and modular solution for managing and displaying file trees within IDEs and code editors. It is designed to provide the following key features:

• Hierarchical File Tree Representation: Displays files and folders in an organized hierarchical tree structure.

• Hover-Navigated Directory: Highlights directories as users navigate through them with clicks. This feature enhances user experience by visually indicating the current directory, offering a clear and interactive method for exploring the directory tree.

• Lazy Loading: Improves loading time by loading child nodes only when they are expanded.

• Asynchronous File System: Executes file operations like expanding, collapsing, and loading files in the FileTree on a background thread, preventing the Main UI Thread from being blocked.

• Customizable Icons: Enables the use of custom icons for files and folders.

• Concurrent FileMap: Maintains a record of recently accessed files and directories, facilitating quick access to previously expanded files and directories.

• RecyclerItemView: Utilizes the built-in RecycledViewPool of RecyclerView to reuse old views, reducing memory usage by avoiding the creation of new views.

Overview

2. Integration

2.1. Dependencies

First, add the FileTree library as a dependency to your project using a build system like Maven or Gradle:

dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
mavenCentral()
maven { url 'https://jitpack.io' }
}
}

dependencies {
implementation 'com.github.Zyron-Official:FileTree:Version'
}

The specific instructions for adding a dependency will depend on your IDE and build system.

2.2. Initialization and Loading

1. Initialize: Initialize FileTree, providing the root directory:

fileTreeView.initializeFileTree(this, "/storage/emulated/0")

2.3. UI Integration

This step involves integrating the FileTree Library within your project, here's a basic example using Android Views:

• Android View-Based (Android/Kotlin/Java): Define FileTreeView in your Layout (XML) to display your FileTree data.

2.4. Event Handling

The FileTree library provides events that you can use to react to user actions within the file tree:

Handle these events in your IDE's logic to perform actions like opening files, displaying properties, or refreshing UI elements.

3. File Operations

The FileTree library provides Event Listeners for performing common file system operations by using FileTreeEventListener Interface.

importcom.zyron.filetree.events.FileTreeEventListenerimportjava.io.FileclassFileOperationExecutor(privatevalcontext:Context) : FileTreeEventListener {
overridefunonFileClick(file:File) {
Toast.makeText(context, "File clicked: ${file.name}", Toast.LENGTH_SHORT).show()
}
overridefunonFolderClick(folder:File) {
Toast.makeText(context, "Folder clicked: ${folder.name}", Toast.LENGTH_SHORT).show()
}
overridefunonFileLongClick(file:File): Boolean {
Toast.makeText(context, "File long-clicked: ${file.name}", Toast.LENGTH_SHORT).show()
returntrue
}
overridefunonFolderLongClick(folder:File): Boolean {
Toast.makeText(context, "Folder long-clicked: ${folder.name}", Toast.LENGTH_SHORT).show()
returntrue
}
}

4. Customizing Icons

The FileTree library allows you to specify custom icons for files and folders.

Here's a basic example to customize icons

importcom.zyron.filetree.provider.FileTreeIconProviderimportjava.io.FileclassFileIconProvider : FileTreeIconProvider {
overridefungetChevronIcon(): Int {
returnR.drawable.ic_chevron
}
overridefungetDefaultFolderIcon(): Int {
returnR.drawable.ic_folder
}
overridefungetDefaultFileIcon(): Int {
returnR.drawable.ic_file
}
overridefungetIconForFolder(folder:File): Int {
returnwhen (folder.name) {
"app"->R.drawable.ic_folder_app
"src"->R.drawable.ic_folder_src
"kotlin"->R.drawable.ic_folder_kotlin
"java"->R.drawable.ic_folder_java
"res"->R.drawable.ic_folder_res
else-> getDefaultFolderIcon()
}
}
overridefungetIconForFile(file:File): Int {
returnwhen (file.name) {
"gradlew.bat"->R.drawable.ic_gradlewbat
"gradlew"->R.drawable.ic_gradlew
"settings.gradle"->R.drawable.ic_gradle_settings
"build.gradle"->R.drawable.ic_gradle_build
"gradle.properties"->R.drawable.ic_gradle_properties
else-> getIconForExtension(file.extension)
}
}
overridefungetIconForExtension(extension:String): Int {
returnwhen (extension) {
"xml"->R.drawable.ic_xml
"java"->R.drawable.ic_java
"kt"->R.drawable.ic_kotlin
else-> getDefaultFileIcon()
}
}
}

5. AttributeSet

Attribute Name	Description	Default Value	XML Attribute	Type
recyclerItemViewCount	Defines the maximum number of items the RecyclerView can hold in its recycled view pool.	200	app:recyclerItemViewCount	Integer
recyclerItemViewEnabled	Enables or disables the use of a recycled view pool for the RecyclerView.	true	app:recyclerItemViewEnabled	Boolean
itemViewCacheSize	Sets the maximum size for the view cache in the RecyclerView.	100	app:itemViewCacheSize	Integer
itemViewCachingEnabled	Enables or disables caching of item views in the RecyclerView.	true	app:itemViewCachingEnabled	Boolean
fileMapMaxSize	Specifies the maximum number of entries in the file map, which caches recently accessed files and directories.	150	app:fileMapMaxSize	Integer
fileMapEnabled	Enables or disables the file map functionality.	true	app:fileMapEnabled	Boolean
fileTreeAnimation	Sets the animation style for expanding and collapsing the file tree.	4	app:fileTreeAnimation	Integer
fileTreeAnimationEnabled	Enables or disables animations for the file tree.	true	app:fileTreeAnimationEnabled	Boolean

Usage Example

To configure these attributes in your XML layout file, use the following syntax:

<com.zyron.filetree.widget.FileTreeView
android:layout_width="match_parent"android:layout_height="match_parent"app:recyclerItemViewCount="250"app:recyclerItemViewEnabled="true"app:itemViewCacheSize="120"app:itemViewCachingEnabled="true"app:fileMapMaxSize="180"app:fileMapEnabled="true"app:fileTreeAnimation="FallDown"app:fileTreeAnimationEnabled="false"/>

Adjust these values according to your application's needs to optimize performance and user experience.

6. Asynchronous File System

The FileTree library typically uses a built-in asynchronous system powered by Kotlin Coroutines to perform core file functions such as expanding, collapsing and loading files in FileTree on the background thread. This ensures that the UI thread remains responsive while the functions are executed.

7. Example (Android view-based)

Here's a basic example of using the FileTree library with Android views:

Define FileTreeView in Layout (XML)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical">
<com.zyron.filetree.widget.FileTreeView
android:id="@+id/file_tree_view"android:layout_width="match_parent"android:layout_height="match_parent" />
</LinearLayout>

Setup FileTree in Activity or Fragment (Kotlin)

importandroidx.appcompat.app.AppCompatActivityimportcom.zyron.filetree.widget.FileTreeViewimportcom.zyron.filetree.resources.FileIconProviderimportcom.zyron.filetree.operationexecutor.FileOperationExecutorimportjava.io.FileclassMainActivity : AppCompatActivity() {
val fileTreeView:FileTreeView= findViewById(R.id.file_tree_view)
val fileIconProvider =FileIconProvider()
val fileOperationExecutor =FileOperationExecutor(requireContext())
fileTreeView.initializeFileTree("/storage/emulated/0", fileOperationExecutor, fileIconProvider, this)
}
