Mybotton.java

    /*Defining Interfaces*/       Public Interfacemyclick{ Public voidOnmyclick (String str); }      /*Initializing interface Variables*/Myclick Myclick=NULL; /*Custom Events*/       Public voidSetonmyclicklistener (Myclick myclick) { This. myclick=Myclick; }  

Mainactivity.java

Xxx.setonmyclicklistener (Mybotton. Myclick () {                            @Override                The abstract method in the public void Onmyclick (String str) {  //replication interface.                Textview1.settext (str);              }          );

Class Ongesturelistener

Gesturedetector.ontouchevent (event);

Onlongpress

Layoutinflater.from (context). Inflater (R.layout.xxx.xml,this,true);
