i have listview has items array i.e string[] stateslist = {"adult 1", "adult 2","adult 3","child 1","child 2","child 1","child 2","child 2"};

now want hide textview if item clicked apart adult.

this function have written populating data in listview 

protected void oncreate(bundle savedinstancestate) {     showpassengerlistview(); }       private void showpassengerlistview() {               string[]  passengerlist ={"adult 1", "adult 2","adult 3","child 1","child 2","child 1","child 2","child 2"};             arrayadapter<string> adapter = new arrayadapter<string>(this,android.r.layout.simple_list_item_1, android.r.id.text1, passengerlist);             listview.setadapter(adapter);             listview.setonitemclicklistener(new onitemclicklistener() {                 @override                 public void onitemclick(adapterview<?> parent, view view,                         int position, long id) { if((passengerlist[position].contains("child"))|| (passengerlist[position].contains("infant"))){                     dateofbirth.setvisibility(view.visible);                 }else{                     dateofbirth.setvisibility(view.gone);                 }                  }         });           **passengerinformationpopup()**     }  public void passengerinformationpopup() {         final dialog dialog= new dialog(iweenbookingpage.this,r.style.dialog_fullscreen);         dialog.setcontentview(r.layout.passenger_details_dialog);          string[] tittlearray ={"mr.","mrs.","ms"};         spinner tittlespinner = (spinner) dialog.findviewbyid(r.id.tittle);          dateofbirth = (textview)dialog.findviewbyid(r.id.dateofbirth);         dateofbirth.setclickable(true);          arrayadapter<string> dataadapter = new arrayadapter<string>(this,                 android.r.layout.simple_spinner_item, tittlearray);           dataadapter.setdropdownviewresource(android.r.layout.simple_spinner_item);         tittlespinner.setadapter(dataadapter);         dialog.show();     }

and getting exception :

08-16 15:51:55.727: e/androidruntime(15553): fatal exception: main 08-16 15:51:55.727: e/androidruntime(15553): java.lang.nullpointerexception 08-16 15:51:55.727: e/androidruntime(15553):    @ com.android.iweentravel.book$5.onitemclick(book.java:184) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.widget.adapterview.performitemclick(adapterview.java:298) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.widget.abslistview.performitemclick(abslistview.java:1114) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.widget.abslistview$performclick.run(abslistview.java:2937) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.widget.abslistview$1.run(abslistview.java:3695) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.os.handler.handlecallback(handler.java:615) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.os.handler.dispatchmessage(handler.java:92) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.os.looper.loop(looper.java:153) 08-16 15:51:55.727: e/androidruntime(15553):    @ android.app.activitythread.main(activitythread.java:4987) 08-16 15:51:55.727: e/androidruntime(15553):    @ java.lang.reflect.method.invokenative(native method) 08-16 15:51:55.727: e/androidruntime(15553):    @ java.lang.reflect.method.invoke(method.java:511) 08-16 15:51:55.727: e/androidruntime(15553):    @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:821) 08-16 15:51:55.727: e/androidruntime(15553):    @ com.android.internal.os.zygoteinit.main(zygoteinit.java:584) 08-16 15:51:55.727: e/androidruntime(15553):    @ dalvik.system.nativestart.main(native method)

how check item has been clicked listview? on basis of item clicked have show/hide textview . main question how identify . items dynamic in listview .but have adult,child ,infant.

you can hide textview that

textview.setvisibility(view.gone)

or 

textview.setvisibility(view.invisible)

depending on want do.

a simple way of identifying item inside onitemclick() method be:

listview.setonitemclicklistener(new onitemclicklistener() {             @override             public void onitemclick(adapterview<?> parent, view view, int position, long id) {                  // example                  if(passengerlist[position].contains("adult)") //                   // or                  textview tv = (textview) view.findviewbyid(r.id.text1);                   if(tv.gettext().tostring().contains("adult)") //             }         });

assembly - 8086 TASM: Illegal Indexing Mode -

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
