  1. A sample project which provides runnable code examples that demonstrate uses of the classes in this project is available in the demo/ folder.
 
  2. The following core classes and xml are the essential interface to create the expandablelayout:

-    1.For using expandable lib module in sample app,include the below library dependency to generate hap file:
-    Add the dependencies in entry/build.gradle as below :
+    and java function
+    
+    ```java
+    	  private ExpandableLayout expandableLayout0;
