}
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="vertical"
>
<com.github.florent37.expansionpanel.ExpansionHeader
android:layout_height="wrap_content"
android:layout_width="match_parent"
app:expansion_headerIndicator="@id/headerIndicator"
app:expansion_layout="@id/expansionLayout"
app:expansion_toggleOnClick="true">
<!-- HEADER -->
...
<!-- HEADER INDICATOR -->
<android.support.v7.widget.AppCompatImageView
android:adjustViewBounds="true"
android:id="@+id/headerIndicator"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_height="wrap_content"
android:layout_marginLeft="16dp"
android:layout_width="wrap_content"
app:srcCompat="@drawable/ic_expansion_header_indicator_grey_24dp" />
</com.github.florent37.expansionpanel.ExpansionHeader>
<com.github.florent37.expansionpanel.ExpansionLayout

- Connect with his Expansion Layout :
expansion_layout
(they must have the same parent) - Define the indicator view with
expansion_headerIndicator
(the id of a view inside the header) - If you want to expand/close when the header is clicked, setup
expansion_toggleOnClick
- You can modify the indicator rotation with
expansion_headerIndicatorRotationExpanded
andexpansion_headerIndicatorRotationCollapsed
You can modify the default expansion of the label with `app:expansion_expanded="false"
Layout can be toggled programmatically with .toggle()
Use .setEnable(true/false)
to enable/disable the expansion
You can setup multiple expansions layout to enable only 1 opened at time
final ExpansionLayoutCollection expansionLayoutCollection = new ExpansionLayoutCollection();
expansionLayoutCollection.add(ex1);
expansionLayoutCollection.add(ex2);
expansionLayoutCollection.openOnlyOne(true);
or direcly in xml with
- ExpansionsViewGroupLinearLayout
- ExpansionsViewGroupFrameLayout
- ExpansionsViewGroupRelativeLayout
- ExpansionsViewGroupConstraintLayout
<com.github.florent37.expansionpanel.viewgroup.ExpansionsViewGroupLinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:expansion_openOnlyOne="true"
android:orientation="vertical">
<!-- Expansions Header & Layouts -->
</com.github.florent37.expansionpanel.viewgroup.ExpansionsViewGroupLinearLayout>
Simply use HorizontalExpansionLayout
instead of ExpansionLayout
<com.github.florent37.expansionpanel.HorizontalExpansionLayout
android:id="@+id/expansionLayout"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<!-- CONTENT -->
</com.github.florent37.expansionpanel.HorizontalExpansionLayout>
