使用这些代码行......`

  ALL_CONTACTS_VIEW.setOnClickListener(new View.OnClickListener() {
       @Override
     public void onClick(View v) {

       ALL_CONTACTS_VIEW.setBackgroundResource(R.drawable.ALL_CONTACTS_VIEW_ACTIVE);
       MY_CONTACT_VIEW.setBackgroundResource(R.drawable.MY_CONTACT_VIEW_INACTIVE);

      }
    });

  MY_CONTACT_VIEW.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

       MY_CONTACT_VIEW.setBackgroundResource(R.drawable.MY_CONTACT_VIEW_ACTIVE);
       ALL_CONTACTS_VIEW.setBackgroundResource(R.drawable.ALL_CONTACTS_VIEW_IN_ACTIVE);

      }
    });
