ExpandableLayout

This ExpandableLayout is like a smooth expand/collapse animation CheckBox, so it can be used anyplace (ListView or RecyclerView).

Usage

Below is an example of a ExpandableLayout, what you need to do is just to set canExpand="true" to a child view/viewgroup.

    <com.kyo.expandablelayout.ExpandableLayout
        android:id="@+id/expandlayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="12dp" >

        <ImageView
            android:id="@+id/imageview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:contentDescription="@null"
            android:scaleType="centerCrop"
            android:src="@drawable/parent" />

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="6dp"
            android:contentDescription="@null"
            android:scaleType="centerCrop"
            android:src="@drawable/child"
            app:canExpand="true" />
    </com.kyo.expandable.ExpandableLayout>

Proguard

Please add the following line in the proguard-rules.pro of your main module. It is because I use ObjectAnimator that maps "height" -> setHeight(ExpandableLayout.LayoutParam.setHeight).

-keep class com.kyo.expandablelayout.** {*;}
