android - Anomailies when an activity calls itself -


i have activty in app uses putextra(int) method pass value 0 first when aactivty started. on pressing next button passes 6,subsequently 12 , on. trouble on pressing next second time found value of index received using getextras method 0.is cause calling activity . code snippet:

package com.movie;   import android.app.activity;  import android.content.intent;  import android.os.bundle;  import android.util.log;  import android.view.view;  import android.view.view.onclicklistener;  import android.view.window;   import android.view.windowmanager;  import android.widget.button;  import android.widget.toast;   public class movielist extends activity implements onclicklistener{  button bm[] = new button[6]; button nxt,prev; string namesdb[]=new string[50]; databaseconnect db; string lang; int start,index,end; public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     requestwindowfeature(window.feature_no_title);     getwindow().setflags(windowmanager.layoutparams.flag_fullscreen,                              windowmanager.layoutparams.flag_fullscreen);     setcontentview(r.layout.mallu_list);     db = new databaseconnect(this);     db.open();      start=this.getintent().getextras().getint("index");      lang =this.getintent().getextras().getstring("lang");       toast.maketext(this, start+"", toast.length_short).show();      log.i("info",start+"");      if(!db.isdata(lang))     {         toast.maketext(this, "no data in database", toast.length_short).show();         finish();         return;     }     end=start+6;     bm[0] = (button) findviewbyid(r.id.bm1);     bm[1] = (button) findviewbyid(r.id.bm2);     bm[2] = (button) findviewbyid(r.id.bm3);     bm[3] = (button) findviewbyid(r.id.bm4);     bm[4] = (button) findviewbyid(r.id.bm5);     bm[5] = (button) findviewbyid(r.id.bm6);      nxt = (button) findviewbyid(r.id.nxt);     prev = (button) findviewbyid(r.id.prev);     if(start==0)     { //      prev.setbackgroundresource(0); //      prev.settext("");     }     else         prev.setonclicklistener(this);       namesdb = db.getmovie("",lang);     (int = 0; start+i < namesdb.length && i<6; i++) {         bm[i].settext(namesdb[start+i]);         bm[i].setonclicklistener(this);     }     int flag=0;     int i=namesdb.length;     log.i("info",i+"");         toast.maketext(this, i+"", toast.length_short).show();         for(int j=5;j>=i-start;j--)         {             bm[j].setbackgroundresource(0);             flag=1;         }     if(flag==1)     { //      nxt.setbackgroundresource(0); //      nxt.settext("");     }     else         nxt.setonclicklistener(this);   }  @override public void onbackpressed() {     // todo auto-generated method stub     super.onbackpressed();     intent myint2 = new intent(this, list.class);      startactivity(myint2); }     @override public void onclick(view v) {     // todo auto-generated method stub     switch (v.getid()) {     case r.id.bm1:         call(namesdb[start],start,lang);         break;     case r.id.bm2:         call(namesdb[start+1],start,lang);         break;     case r.id.bm3:         call(namesdb[start+2],start,lang);         break;     case r.id.bm4:         call(namesdb[start+3],start,lang);         break;     case r.id.bm5:         call(namesdb[start+4],start,lang);         break;     case r.id.bm6:         call(namesdb[start+5],start,lang);         break;      case r.id.nxt:         int i=namesdb.length;         intent myint2 = new intent(this,movielist.class);      myint2.putextra("index",end);     myint2.putextra("lang",lang);     startactivity(myint2);     case r.id.prev:         if(start==0)         {             prev.setbackgroundresource(0);         }         else         {          myint2 = new intent(this,movielist.class);      myint2.putextra("index",start-6);     myint2.putextra("lang",lang);     startactivity(myint2);}         break;      }  }  public void call(string name,int start2,string lang) {      intent myint = new intent(this, detail.class);     myint.putextra("nameid", name);     myint.putextra("index", start2);     myint.putextra("lang", lang);      startactivity(myint); }    }

here's problem. part of switch statement:

case r.id.nxt:     int i=namesdb.length;     intent myint2 = new intent(this,movielist.class);     myint2.putextra("index",end);     myint2.putextra("lang",lang);     startactivity(myint2);

is missing break @ end. falls through next case, starts activity different extras.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
