listview - Swipe right display button in android custom list view -

-

i trying implement, show button on swipe right in custom list view. problem facing right is, implemented onswipetouchlistener found online. able see swipe button. not consistent, mean if swipe right on 1 row, button displaying in other row. tried.

i created adapter holding view 

//transactionadddropviewholder           public static final class transactionadddropviewholder {      public view moveupbutton = null;     public view movedownbutton = null;     public view withdrawbutton = null;     public view reviewbutton = null;      public view approvebutton = null;     public view rejectbutton = null;      public linearlayout addcontainer = null;     public linearlayout dropcontainer = null;        public void swipebuttons() {         adddroplistview.setontouchlistener(new onswipetouchlistener() {              public void onswiperight() {                 withdrawbutton.setvisibility(view.visible);             }              public void onswipeleft() {                 withdrawbutton.setvisibility(view.invisible);             }         });     }      public void showuserbuttons() {         this.moveupbutton.setvisibility(view.visible);         this.movedownbutton.setvisibility(view.visible);         // this.withdrawbutton.setvisibility(view.visible);     }      public void hideuserbuttons() {         this.moveupbutton.setvisibility(view.gone);         this.movedownbutton.setvisibility(view.gone);         // this.withdrawbutton.setvisibility(view.gone);     }   }

and custom view displaying onswipebutton

@override     public view getview(final int position, view convertview,             viewgroup parent) {          final transactionadddrop adddropdata = this.adddroplist.get(position);          transactionadddropviewholder holder = null;          if (convertview == null) {             convertview = inflater.inflate(r.layout.fragment_pending_transaction_list_item, null);             holder = new transactionadddropviewholder();  holder.withdrawbutton = convertview.findviewbyid(r.id.pendingtransactionitem_withdrawbutton);             holder.addcontainer = (linearlayout) convertview.findviewbyid(r.id.pendingtransactionitem_addcontainer);             **holder.swipebuttons();**              convertview.settag(holder);         } else {             holder = (transactionadddropviewholder) convertview.gettag();             holder.swipebuttons();          }

and onswipetouchlistener class

    private final class gesturelistener extends simpleongesturelistener {      private static final int swipe_threshold = 100;     private static final int swipe_velocity_threshold = 100;      @override     public boolean ondown(motionevent e) {         return true;     }      @override     public boolean onfling(motionevent e1, motionevent e2, float velocityx, float velocityy) {         boolean result = false;         try {             float diffy = e2.gety() - e1.gety();             float diffx = e2.getx() - e1.getx();             if (math.abs(diffx) > math.abs(diffy)) {                 if (math.abs(diffx) > swipe_threshold && math.abs(velocityx) > swipe_velocity_threshold) {                     if (diffx > 0) {                         onswiperight();                     } else {                         onswipeleft();                     }                 }             } else {                 if (math.abs(diffy) > swipe_threshold && math.abs(velocityy) > swipe_velocity_threshold) {                     if (diffy > 0) {                         onswipebottom();                     } else {                         onswipetop();                     }                 }             }         } catch (exception exception) {             exception.printstacktrace();         }         return result;     } }

adding 1 more question. getting total count of view. want display in different layout. here oncreatedview

public view oncreateview(layoutinflater inflater, viewgroup container,         bundle savedinstancestate) {      fragmentpendingtrades = inflater.inflate(r.layout.fragment_transactions_pending, container, false);     pendingtradesview = inflater;      return fragmentpendingtrades; }      public void onviewcreated(final view view, final bundle savedinstancestate) {      this.adddroplistview = (listview) view.findviewbyid(r.id.transactions_pending_transactionslistview);     this.adddropadapter = new transactionadddropadapter(pendingtradesview);     this.adddroplistview.setadapter(this.adddropadapter);     this.emptytransationscontainer = view.findviewbyid(r.id.transactions_pending_transactions_emptycontainer);        textview gettotalcount = (textview) view.findviewbyid(r.id.transactions_pending_transactionsadddropcount);      gettotalcount.settext(""+adddroplistview.getcount());    }

so, can done 2 ways see it:

  1. listen swipes on entire list, figure out row swiped occurred on, , show/hide button correct row.
  2. listen swipes on each row, , show/hide button row.

right setting listener on list, trying apply show/hide button attached in adapter. in way, doing half of each solution. have, suggest go option #2.

in transactionadddropviewholder, need reference root view in row layout, can set onswipetouchlistener it.

public static final class transactionadddropviewholder {      public view rootview = null;      // other code      public void swipebuttons() {         rootview.setontouchlistener(new onswipetouchlistener() {              public void onswiperight() {                 withdrawbutton.setvisibility(view.visible);             }              public void onswipeleft() {                 withdrawbutton.setvisibility(view.invisible);             }         });     }      // other code  }

next, in getview method, update transactionadddropviewholder gets reference root view in layout.

@override public view getview(final int position, view convertview, viewgroup parent) {      final transactionadddrop adddropdata = this.adddroplist.get(position);      transactionadddropviewholder holder = null;      if (convertview == null) {         convertview = inflater.inflate(r.layout.fragment_pending_transaction_list_item, null);         holder = new transactionadddropviewholder();          // reference root of row layout         holder.rootview = convertview.findviewbyid(r.id.swiperight);           holder.withdrawbutton = convertview.findviewbyid(r.id.pendingtransactionitem_withdrawbutton);         holder.addcontainer = (linearlayout) convertview.findviewbyid(r.id.pendingtransactionitem_addcontainer);          holder.swipebuttons();         convertview.settag(holder);     } else {         holder = (transactionadddropviewholder) convertview.gettag();         holder.swipebuttons();      } }

there 1 more issue have, button correctly show when swiped, if user continues scroll, appear on other rows. because listview recycles row's views. suggest either 2 things:

  1. when user starts scrolling again after button present, hide again. ios "swipe delete" in lists.
  2. use boolean store in data object if row in mode button visible, isdeleteshowing example. in onswipe callbacks, set isdeleteshowing true/false. lastly, in getview, show/hide of button there depending on isdeleteshowing data row.

hope helps.

How to calculate SNR of signals in MATLAB? -

i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
