Header

  1. Connect with his Expansion Layout : expansion_layout (they must have the same parent)
  2. Define the indicator view with expansion_headerIndicator (the id of a view inside the header)
  3. If you want to expand/close when the header is clicked, setup expansion_toggleOnClick
  4. You can modify the indicator rotation with expansion_headerIndicatorRotationExpanded and expansion_headerIndicatorRotationCollapsed

Layout

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

Open only one

screen

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);

<com.github.florent37.expansionpanel.viewgroup.ExpansionsViewGroupLinearLayout
