Usage

ExpandableLayout

Declare an ExpandableLayout inside your XML layout file. You also need to other layouts for header and content:

  <com.andexert.expandablelayout.library.ExpandableLayout
         android:id="@+id/expandableLayout"
         xmlns:expandable="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         expandable:headerLayout="@layout/view_header"
         expandable:contentLayout="@layout/view_content"/>

ExpandableLayoutItem && ExpandableLayoutItem

You can use ExapandableLayout in an ExpandableLayoutListView with ExpandableLayoutItem as row :

ExpandableLayoutItem

  <com.andexert.expandablelayout.library.ExpandableLayoutItem
         android:id="@+id/expandableLayout"
         xmlns:expandable="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         expandable:headerLayout="@layout/view_header"
         expandable:contentLayout="@layout/view_content"/>

ExpandableLayoutListView

  <com.andexert.expandablelayout.library.ExpandableLayoutListView
         android:id="@+id/expandableLayout"
         xmlns:expandable="http://schemas.android.com/apk/res-auto"
         android:layout_width="match_parent"
         android:layout_height="match_parent"/>

If you want to manage the OnScroll, you have to use OnExpandableLayoutScrollListener and don't forget to call super in each method.

You can call dynamically open, close and isOpened from an ExpandableLayout object.

Customization

You can change duration of the animation:

  • app:duration [integer def:200] --> Duration of the animation

Troubleshooting

If you want to use the ExpandableLayoutListView with EditText, you have to set android:windowSoftInputMode="adjustPan" to prevent the ListView to redraw itself and close the ExpandableLayoutItem.
