Before you try to use this library

This library is forked and modified for the app Cometin I tried making the library as functional for others but there might be some elements you don't like.

ExpandableCardView

An Android library that lets you create in a simple, fast and hassle-free way a CardView in which you can insert your custom layout and just expand and collapse without even writing a single Java/Kotlin line of code.

This component follows the Material Design Guidelines.

Demo

Get it on the Google Play Store.

Setup

First of all, include the dependency in your app build.gradle:

Stable

implementation 'com.github.Stjinchan:ExpandableCardView:1.2.2'

Or get the aar in the Releases section.

Declaring the view

After you have the Library correctly setup, just declare the ExpandableCardView in your xml:

<host.stjin.expandablecardview.ExpandableCardView
    android:id="@+id/profile"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:title="Passengers"
    app:icon="@drawable/ic_person"
    app:inner_view="@layout/mycustomview"
    app:expandOnClick="true"
    app:animationDuration="300"
    app:cardStrokeWidth="2dp"
    app:startExpanded="false"/>

The only required attributes are inner_view and title. The other attributes are optional.

You can specify a custom title and icon on the header on the card by setting the attribute app:title and app:icon respectively.

After you created the base xml, just create your custom layout and place it inside your layout folder.

Now just pass your newly created layout resource to the app:inner_view attribute. By setting the attribute app:expandOnClick="true" the card will have a default behaviour (expand/collapse on click); By setting the animationDuration attribute you can set a custom animation time, and by setting the startExpanded attribute the card will be automatically expanded when inflated.

Done! Now your ExpandableCardView is ready to roll.

Usage

If you want some basic Expandable Card without any custom behaviour, setting the view in the XML is enough. Otherwise just declare your ExpandableCardView in your Activity/Fragment and you're ready to use its methods.

Styling

app:expandOnClick="true"
app:expandableCardRipple="true"
app:expandableCardRadius="6dp"
app:expandableCardStrokeWidth="2dp"
app:expandableCardElevation="4dp"
app:expandableCardStrokeColor="@color/colorAccent"
app:expandableCardArrowColor="@color/colorAccent"
app:expandableCardTitleColor="@color/colorAccent"
app:expandableCardColor ="@color/colorAccent"
app:expandableCardTitleBold="true"
app:expandableCardTitleSize="14sp"
app:animationDuration="900"
app:startExpanded="true"
app:showSwitch="true"

Java

ExpandableCardView card = findViewById(R.id.profile);

 //Do stuff here

Kotlin

val card : ExpandableCardView = findViewById(R.id.profile)

 //Do stuff here

You can use expand() and collapse() to respectively expand and collapse the card, and use isExpanded() to check if the card is expanded or not. You can change the title and icon of the card dynamically by using setTitle() and setIcon() methods.

You can also set an OnExpandedListener to the card:

Java

card.setOnExpandedListener(new OnExpandedListener() {
    @Override
    public void onExpandChanged(View v, boolean isExpanded) {
        Toast.makeText(applicationContext, isExpanded ? "Expanded!" : "Collapsed!", Toast.LENGTH_SHORT).show();
    }
});

card.setOnSwitchChangeListener(new OnSwitchChangeListene() {
    @Override
    public void OnSwitchChangeListener(View v, boolean isChecked) {
        Toast.makeText(applicationContext, isChecked ? "Checked!" : "Not checked!", Toast.LENGTH_SHORT).show();
    }
});

Kotlin

card.setOnExpandedListener { view, isExpanded ->
    Toast.makeText(applicationContext, if(isExpanded) "Expanded!" else "Collapsed!", Toast.LENGTH_SHORT).show()
 }

 card.setOnSwitchChangeListener { view, isChecked ->
    Toast.makeText(applicationContext, if(isChecked) "Checked!" else "Not checked!", Toast.LENGTH_SHORT).show()
 }
