Android Interface Interface Transfer value

Now assume that there are two classes Aclass.class and Bactivity.class, passing the value in a to the B call

1, the code in Aclass.class is as follows

public class AClass implements {  //Get interface Object     private Onaclasslistener Aclasslistener;  //Construction Method  Private AClass () {  }  //Send data public     void sends () {if (aclasslistener!= null) {  
   aclasslistener.onaclass ("Pass the value Here");               }  }      For B-bound interface public      void Setonaclass (Onaclasslistener mlistener) {          this.aclasslistener = Mlistener;}      Define interface Public      interface Onaclasslistener {          void Onaclass (String str);      }　　　　　        

　　

　　

2, the code in Bactivity.class is as follows

public class Bactivity extends Appcompatactivity implements A.onaclasslistener {             @Override    protected void OnCreate (Bundle savedinstancestate) {        super.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main); AClass a = new AClass ();        Binding interface        A.setonaclass (this); A.sends (); Call data Send}             @Override public    void Onplayercache (String str) {        log.e ("bactivity", "Incoming string:" + str);   }
