android - getCount() of baseAdapter called many times -


i have class extends baseadapter use insert icon , textview each row of listview inside drawer

public class navrightdrawerlistadapter extends baseadapter {  private context context; linkedlist<string> usernameusedforlistview; map<string, bitmap> urluserimage;  public navrightdrawerlistadapter(context context, linkedlist<string> usernameusedforlistview, map<string, bitmap> returnbitmapfromurl) {     this.context = context;     this.usernameusedforlistview = usernameusedforlistview;     this.urluserimage = returnbitmapfromurl; }  @override public view getview(int position, view convertview, viewgroup parent) {     int count = 0;     if (convertview == null) {         layoutinflater minflater = (layoutinflater) context.getsystemservice(activity.layout_inflater_service);         convertview = minflater.inflate(r.layout.drawer_list_of_action, null);     }      imageview imgicon = (imageview) convertview.findviewbyid(r.id.icon);     textview txttitle = (textview) convertview.findviewbyid(r.id.title);      imgicon.setimagebitmap(urluserimage.get(usernameusedforlistview.get(count)));     txttitle.settext(usernameusedforlistview.get(count));     count++;     return convertview; }  @override public int getcount() {     return usernameusedforlistview.size(); }  @override public object getitem(int position) {     // todo auto-generated method stub     return null; }  @override public long getitemid(int position) {     // todo auto-generated method stub     return 0; }

my list size 1, , getview called 1 time,normally, getcount called 6 times? why? normal behaviour?

i didn't implement method,getitem() , getitemid(),because don't need them, have implement them anyway?

thanks lot.

adapter methods may called arbitrary number of times while adapterview readying , laying out child views. so, yes, it's normal.

i'm unable find source explicitly states case getcount(), this answer romain guy notes how there no guarantee how many times getview() called. 1 can see how method interplay getcount(), would, therefore, need called uncertain number of times.

ruby - How do I merge two hashes into a hash of arrays? -

http://codepad.org/wmyzqlis i'd merge these 2 arrays: a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } into hash looks this: {:a => ["a", "1"], :b => ["b", "b"], :c => [nil, "c"], :d => ["d", nil] } this doesn't work: p a.merge(b) { |k, v1, v2| [v1, v2] } # {:c=>"c", :a=>["a", "1"], :b=>["b", "b"], :d=>"d"} it's because hash#merge call block duplicate keys. a = { :a => 'a', :b => 'b', :d => 'd' } b = { :a => '1', :b => 'b', :c => 'c' } hash[(a.keys|b.keys).map { |key| [key, [a.fetch(key, nil), b.fetch(key, nil)]] }] # => {:a=>["a", "1"], :b=>["b", "b"], :d=>["d", nil], :c=>...
