Используйте эти строки кода ... `

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); 

     } 
    });
