listview - Android: Removing a List Item on CheckBox-Click checks next Item -


i have weird behavior. have to-do-list-like function remove listview item when checkbox clicked. however, causes next checkbox checked instantly. idea?

@override public void oncheckboxclick(int position) {      mtasklist.remove(position);     adapter.notifydatasetchanged();  }

it click gets carried on next item, because item removed fast.

edit:

this customadapters getview() method. rpg themed task list.

 @nonnull @override public view getview(final int position, @nullable view convertview, @nonnull viewgroup parent) {     view taskitemview = convertview;     if (taskitemview == null) {         taskitemview = layoutinflater.from(getcontext()).inflate(r.layout.task_item, parent, false);     }      taskitem currenttaskitem = getitem(position);      //set item texts accordingly     textview taskname = (textview) taskitemview.findviewbyid(r.id.task_name_xml);     taskname.settext(currenttaskitem.getname());     textview difficultytext = (textview) taskitemview.findviewbyid(r.id.task_difficulty_xml);     difficultytext.settext(currenttaskitem.getdifficultytext());     textview expgaintext = (textview) taskitemview.findviewbyid(r.id.exp_win_xml);     expgaintext.settext("" + currenttaskitem.getexpamountgained() + " exp");     textview goldgaintext = (textview) taskitemview.findviewbyid(r.id.currency_win_xml);     goldgaintext.settext("" + currenttaskitem.getgoldamountgained());     checkbox checkbox = (checkbox) taskitemview.findviewbyid(r.id.task_checkbox_xml);     checkbox.setchecked(false);     //set checkbox listener      checkbox.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view view) {             mlistener.oncheckboxclick(position);         }     });      return taskitemview;  }

there few things need change.

  1. always use recycled view pattern listviews. faster , lot more memory efficient

add view holder class task:

class taskviewholder {     textview taskname;     textview difficultytext;      taskviewholder(view root)     {         taskname = (textview) taskitemview.findviewbyid(r.id.task_name_xml);         difficultytext = (textview) taskitemview.findviewbyid(r.id.task_difficulty_xml);     } }

then change getview() this:

taskviewholder holder;     if(convertview == null)     {         convertview = layoutinflater.from(getcontext()).inflate(r.layout.task_item, parent, false);         holder = new taskviewholder(convertview);         convertview.settag(holder);     }     else         holder = (taskviewholder)convertview.gettag();      taskitem currenttaskitem = getitem(position);      holder.taskname.settext(currenttaskitem.getdifficultytext());     holder.difficultytext.settext(currenttaskitem.getdifficultytext()); return convertview;

i have included 2 of views idea.

  1. when set oncheckchanged listener set this:

    holder.checkbox.settag(position); holder.setonclicklistener(this);

then inside onclick(view v) callback this:

//check if correct view int position = (int)v.gettag(); taskitem t = getitem(position); //do here

again, haven't included views in holder, should add them. should fix issue.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
