I described the adapter for ListView inherited from ArrayAdapter, however the getView method is called 12 times instead of 4x. The only solution that was found was to set the match_parent parameter in the layout_width and layout_height, but this did not help. How else can you get repeat calls to getView?

Adapter code

public ExecuteAdapter( int resId, ArrayList textPack, ArrayList imagePack, int mainLayout, Data summaryPack, int summaryLayout, Data summaryCommandPack){ super(GlobalActivity.getActivity(), resId, new String[textPack.size()]); this.textPack = textPack; this.imagePack = imagePack; this.mainLayout = mainLayout; this.summaryLayout = summaryLayout; this.summaryPack = summaryPack; this.summaryCommandPack = summaryCommandPack; new LogExt("list size - "+textPack.size()); } public View getView (int pos, View view, ViewGroup parent){ LayoutInflater inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); currentView = inflater.inflate(mainLayout, parent, false); linearLayout = (LinearLayout) currentView.findViewById(R.id.linear_layout); loadText(pos); loadImage(pos); createSummaryField(pos); new LogExt("call getView"); return currentView; }

Log output

  • Yes, ViewHolder helped, thanks. - Kota1921
  • Yes, here not only the ViewHolder is needed, but also the additional condition that the View is already created, which is actually described in any normal guide. But in general, getView can twitch quite often, and this is a personal matter of ListView. There is no need to lay in the fact that getView will twitch for a certain number of times or in some particular order. - KoVadim

in order for each new item of the list to re-create it again, use ViewHolder in the adapter
