android - More than one contentDescription for a button -

in activity have method reads contentdescription of button , phone number , calls it.

i have list of departments in company. if same department have more 1 number should do. how add more 1 contentdescription button pop dialog allows user choose between number should call.

public class contactus extends appcompatactivity {  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_contact_us);      imageview = (imageview) findviewbyid(r.id.back);     back.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             intent = new intent(contactus.this , introduction.class);             startactivity(i);             overridependingtransition(r.animator.slide_in, r.animator.slide_out);          }     }); }  public void onclickcall(view view) {      final string phonenumber = view.getcontentdescription().tostring().trim();      dialoginterface.onclicklistener dialogclicklistener = new dialoginterface.onclicklistener() {         @override         public void onclick(dialoginterface dialog, int which) {             switch (which){                 case dialoginterface.button_positive:                     //yes button clicked                     intent intent = new intent(intent.action_dial, uri.parse("tel://" + phonenumber));                     startactivity(intent);                     break;                  case dialoginterface.button_negative:                     //no button clicked                     break;             }         }     };     alertdialog.builder builder = new alertdialog.builder(this);     builder.setmessage("test alert").setpositivebutton("yes", dialogclicklistener)             .setnegativebutton("no", dialogclicklistener).show();  }  public void onclickmail(view view) {       string mailaddress = view.getcontentdescription().tostring().trim();     intent intent = new intent(intent.action_send);     intent.settype("plain/text");     intent.putextra(intent.extra_email, new string[] { mailaddress});     intent.putextra(intent.extra_subject, "subject");     intent.putextra(intent.extra_text, "mail body");     startactivity(intent.createchooser(intent, ""));  } } 

when setting content description button append them commas separated.

after appending phone numbers content description //phonenumber1,phonenumber2,phonenumber3

now read content description view

final string allphonenumbers = view.getcontentdescription().tostring().trim();  //say phonenumber1,phonenumber2,phonenumber3  string[] arrphonenumbers = allphonenumbers .split(","); 

now have phone numbers in array.
