Guten Tag
Ich hoffe ihr könnt mir Helfen

Habe ein Filter für Search ListView erstellt, das Problem ist es funktioniert nicht, komme einfach nicht mehr weiter :-(

Code: 
public class PzCustomAdapter extends BaseAdapter implements Filterable {


    String[] name,einheit;
    private List<String>filteredData = null;
    Context context;
    int [] imageId;
    private static LayoutInflater inflater=null;

    public PzCustomAdapter(MainActivityPz mainActivity, String[] prgmNameList, int[] prgmImages, String[] prgmNameEinheit) {
        // TODO Auto-generated constructor stub
        name=prgmNameList;
        einheit=prgmNameEinheit;
        context=mainActivity;
        imageId=prgmImages;
        inflater = ( LayoutInflater )context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return name.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }
    @Override
    public Filter getFilter() {
        return new Filter() {

            /* (non-Javadoc)
             * @see android.widget.Filter#performFiltering(java.lang.CharSequence)

                // TODO Auto-generated method stub
            /*
             * Here, you take the constraint and let it run against the array
             * You return the result in the object of FilterResults in a form

             */

Hallo,

genauer Angaben wären nicht schlecht, wo genau ist das Problem. Filter er gar nicht, oder Filter er zu viel weg, LogCat ausgaben wenn die App Beendet wird, oder oder oder..

Gruß
 
@123thomas

Hi, der Filtert gar nicht :-(

Die Liste bleibt unverändert

App Stürzt auch nicht ab
 
du verwendest dein filteredData ja gar nicht, wie soll denn da was passieren?
Zumindest nicht im gezeigten Code.
 
@deek

Danke schon mal für deine Antwort , habe jetzt eine DetailsData Class erstellt und den getFilter angepasst, trotzdem kein Erfolg ;-( hast du eine Idee wie ich das zum Laufen bekomme ?

Code: 
public class PzDetailsData {

    String pznamen;
    String pzeinheit;
    int pzpicture;

    public PzDetailsData() {
        super();
        this.pznamen = pznamen;
        this.pzeinheit = pzeinheit;
        this.pzpicture = pzpicture;
    }

    public String getPznamen() {
        return pznamen;
    }
    public void setPznamen(String pznamen) {
        this.pznamen = pznamen;
    }
    public String getPzeinheit(){
        return pzeinheit;
    }
    public  void setPzeinheit(String pzeinheit){
        this.pzeinheit = pzeinheit;
    }
    public int getPzpicture() {
        return pzpicture;
    }
    public void setPzpicture(int pzpicture) {
        this.pzpicture = pzpicture;
    }
}

Code: 
@Override
    public Filter getFilter() {

        if(valueFilter == null){
            valueFilter = new ValueFilter();
        }

        return valueFilter;
    }

    private class ValueFilter extends Filter {


        @Override
        protected FilterResults performFiltering(CharSequence constraint) {

            FilterResults filterResults = new FilterResults();
            ArrayList<PzDetailsData> tempList=new ArrayList<PzDetailsData>();
            //constraint is the result from text you want to filter against.
            //objects is your data set you will filter from
            if(constraint != null && objects!=null) {
                int length=objects.size();
                int i=0;
                while(i<length){
                    PzDetailsData item=objects.get(i);
                    //do whatever you wanna do here
                    //adding result set output array

                    tempList.add(item);

                    i++;
                }
                //following two lines is very important
                //as publish result can only take FilterResults objects
                filterResults.values = tempList;
                filterResults.count = tempList.size();
            }
            return filterResults;
        }

        @SuppressWarnings("unchecked")
        @Override
        protected void publishResults(CharSequence charSequence, FilterResults results) {

            objects = (ArrayList<PzDetailsData>) results.values;
            if (results.count > 0) {
                notifyDataSetChanged();
            } else {
                notifyDataSetInvalidated();
            }

        }

    };
