Purpose

This library provides a lightweight List-Grid Switch View that can be used to switch between list and grid modes. In Android projects, we often need to display a list of items in both list and grid modes. It's easy to create a custom view for this purpose but it's even easier to use this library. The switch view is highly customizable and can be used in both Kotlin and Java projects.

Features

• Lightweight
• Highly customizable
• Supports both Kotlin and Java
• Can be used in other cases as well (not just for switching between list and grid modes). Any two icons can be used to switch between two modes.

Demo

Prerequisites

If you're using old gradle versions, add this in your root build.gradle file (not your module build.gradle file):

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

If you're using new gradle versions, add this in your root settings.gradle file (not your module build.gradle file):

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

Dependency

Add this to your module's build.gradle file (latest version ):

dependencies {
    ...
    implementation 'com.github.CuteLibs:ListGridSwitchView:0.1.0'
}

or build.gradle.kts if you're using Kotlin DSL:

dependencies {
    ...
    implementation("com.github.CuteLibs:ListGridSwitchView:0.1.0")
}

Usage

XML

<io.github.cutelibs.listgridswitchview.CustomListGridSwitchView
    android:id="@+id/customListGridSwitchView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

Kotlin

val switchView = binding.customListGridSwitchView
switchView.setListener { mode ->
    when (mode) {
        CustomListGridSwitchView.SwitchMode.LIST -> {
            // Handle list mode
        }

        CustomListGridSwitchView.SwitchMode.GRID -> {
            // Handle grid mode
        }
    }
}
switchView.shouldRememberState(true)

Java

CustomListGridSwitchView switchView = binding.customListGridSwitchView;
switchView.setListener(new Function1<CustomListGridSwitchView.SwitchMode, Unit>() {
    @Override
    public Unit invoke(CustomListGridSwitchView.SwitchMode mode) {
        switch (mode) {
            case LIST:
                // Handle list mode
                break;
            case GRID:
                // Handle grid mode
                break;
        }
        return null;
    }
});
switchView.shouldRememberState(true);

Customization

XML

<io.github.cutelibs.listgridswitchview.CustomListGridSwitchView
    android:id="@+id/customListGridSwitchView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:setMode="list" <!-- Sets the initial mode -->
    app:iconColor="@color/colorAccent" <!-- Color filter for the list and grid icons -->
    app:listIcon="@drawable/ic_list_custom_switch_view" <!-- Custom drawable for the list icon -->
    app:gridIcon="@drawable/ic_grid_custom_switchview" <!-- Custom drawable for the grid icon -->
    />

Kotlin

val switchView = binding.customListGridSwitchView

// returns the current mode
val currentMode = switchView.getCurrentMode()


// set custom list icon
switchView.setListIcon(ContextCompat.getDrawable(context, R.drawable.my_custom_list_icon))

// Set custom grid icon
switchView.setGridIcon(ContextCompat.getDrawable(context, R.drawable.my_custom_grid_icon))

// Set mode programmatically
switchView.setMode(CustomListGridSwitchView.SwitchMode.GRID)


// Set listener to observe mode changes
switchView.setListener { mode ->
    when (mode) {
        CustomListGridSwitchView.SwitchMode.LIST -> {
            // Handle list mode
        }

        CustomListGridSwitchView.SwitchMode.GRID -> {
            // Handle grid mode
        }
    }
}


// Tell the switch view to remember its state across app launches
switchView.shouldRememberState(true)

// Clear the saved state (use this when you want to reset the switch view's memory)
// switchView.clearState()

Java

CustomListGridSwitchView switchView = binding.customListGridSwitchView;

// Returns the current mode
CustomListGridSwitchView.SwitchMode currentMode = switchView.getCurrentMode();

// Set custom list icon
switchView.setListIcon(ContextCompat.getDrawable(this, R.drawable.my_custom_list_icon));

// Set custom grid icon
switchView.setGridIcon(ContextCompat.getDrawable(this, R.drawable.my_custom_grid_icon));

// Set mode programmatically
switchView.setMode(CustomListGridSwitchView.SwitchMode.GRID);

// Set listener to observe mode changes
switchView.setListener(new Function1<CustomListGridSwitchView.SwitchMode, Unit>() {
    @Override
    public Unit invoke(CustomListGridSwitchView.SwitchMode mode) {
        switch (mode) {
            case LIST:
                // Handle list mode
                break;
            case GRID:
                // Handle grid mode
                break;
        }
        return null;
    }
});

// Tell the switch view to remember its state across app launches
switchView.shouldRememberState(true);

// Clear the saved state (use this when you want to reset the switch view's memory)
// switchView.clearState();

Notes

• The switch view's default mode is LIST.
• The switch view's default icon color is #000000 (black).
• The switch view's default list icon is R.drawable.ic_list_custom_switch_view.
• The switch view's default grid icon is R.drawable.ic_grid_custom_switchview.
• The switch view's default state is not remembered across app launches.
• The saved state will override the initial mode set in XML (app:setMode) or programmatically (setMode()).
• If you are using it in Java make sure you've enabled Kotlin support in your project by adding the following to your app's build.gradle file:

implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
