[android] AutoCompleteTextView 때문에 Filterable 을 적용한 경우 example.

android, AutoCompleteTextView 때문에 Filterable 을 적용한 경우 example.

AutoCompleteTextView 때문에 Filterable 을 적용한 경우, 어떤 sequence 로 함수들이 불릴까?

1. getFilter ( 1회만 불림 )

2. 글자 하나당 performFiltering, publishResults 가 순차적으로 불림.

3. publishResults 에서 notifyDataSetChanged 가 불리면getCount 를 부르면서 일반적인 list drawing 이 진행됨.

private static class AutoCompleteAdapter extends BaseAdapter implements Filterable{

private List<GeoInfo> mGeoInfos;

public void setGeoInfos( List<GeoInfo> geoInfos ){

mGeoInfos = geoInfos;

notifyDataSetChanged();

}

public void clear() {

if ( !Utils.isEmptyList( mGeoInfos ) ) 

mGeoInfos.clear();

}

@Override

public int getCount() {

if ( Utils.isEmptyList( mGeoInfos ) ) return 0;

return mGeoInfos.size();

}

@Override

public GeoInfo getItem(int position) {

return mGeoInfos.get( position );

}

@Override

public long getItemId(int position) {

return position;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

if ( convertView == null )

convertView = ViewUtils.getInflatedView( parent.getContext(), android.R.layout.simple_list_item_2 );

GeoInfo geoInfo = mGeoInfos.get( position );

((TextView)convertView.findViewById( android.R.id.text1 )).setText( geoInfo.getShortName() );

((TextView)convertView.findViewById( android.R.id.text2 )).setText( geoInfo.getLongName() );

return convertView;

}

@Override

public Filter getFilter() {

return new Filter(){

@Override

protected FilterResults performFiltering(CharSequence constraint) {

if ( !Utils.isAssembledKorean( constraint.toString(), ' ' ) ) return null;

FilterResults filterResults = new FilterResults();

if ( !Utils.isEmptyList( mGeoInfos ) ){

filterResults.values = mGeoInfos;

filterResults.count =  mGeoInfos.size();

}

return filterResults;

}

@Override

protected void publishResults(CharSequence constraint, FilterResults results) {

if ( results == null || results.count == 0 )

notifyDataSetInvalidated();

else

notifyDataSetChanged();

}

};

}

}
