Cómo buscar en la vista de lista personalizada

Realice cambios en su clase adaptadora de acuerdo con este código de ejemplo y concéntrese en el método getFilter aunque he pegado la clase completa del adaptador para su referencia.

 public class CustomListAdapter extends BaseAdapter { private Activity activity; private LayoutInflater inflater; private List<Movie> movieItems; private List<Movie> movieItemSearched = null; private List<Movie> originalMovieList; ImageLoader imageLoader = AppController.getInstance().getImageLoader(); public CustomListAdapter(Activity activity, List<Movie> movieItems) { this.activity = activity; this.movieItems = movieItems; this.originalMovieList = new ArrayList<Movie>(movieItems); this.movieItemSearched = new ArrayList<Movie>(); this.movieItemSearched.addAll(movieItems); } //Add Below Method public void reloadData(){ this.originalMovieList = new ArrayList<Movie>(movieItems); notifyDataSetChanged(); } @Override public int getCount() { return movieItems.size(); } @Override public Object getItem(int location) { return movieItems.get(location); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { if (inflater == null) inflater = (LayoutInflater) activity .getSystemService(Context.LAYOUT_INFLATER_SERVICE); if (convertView == null) convertView = inflater.inflate(R.layout.list_row, null); if (imageLoader == null) imageLoader = AppController.getInstance().getImageLoader(); NetworkImageView thumbNail = (NetworkImageView) convertView .findViewById(R.id.thumbnail); TextView title = (TextView) convertView.findViewById(R.id.title); TextView rating = (TextView) convertView.findViewById(R.id.rating); TextView genre = (TextView) convertView.findViewById(R.id.genre); TextView year = (TextView) convertView.findViewById(R.id.releaseYear); TextView appuser = (TextView) convertView.findViewById(R.id.appuser); TextView reg = (TextView) convertView.findViewById(R.id.reg); // LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(100, 100); // iv.setLayoutParams(layoutParams); // getting movie data for the row Movie m = movieItems.get(position); // thumbnail image thumbNail.setImageUrl(m.getThumbnailUrl(), imageLoader); // title title.setText(m.getTitle()); // rating rating.setText(m.getRating()); // genre genre.setText(m.getGenre()); appuser.setText(m.getApp_user()); reg.setText(m.getReg()); year.setText(String.valueOf(m.getYear())); return convertView; } public Filter getFilter(ComponentName cn) { return new Filter() { @Override protected FilterResults performFiltering(CharSequence constraint) { String filterString = constraint.toString().toLowerCase(); FilterResults results = new FilterResults(); final List<Movie> list = originalMovieList; int count = list.size(); final ArrayList<Movie> nlist = new ArrayList<Movie>(count); String filterableString1,filterableString2; /* for (int i = 0; i < count; i++) { filterableString = list.get(i).getTitle(); if (filterableString.toLowerCase().contains(filterString)) { // nlist.add(filterableString); nlist.add(list.get(i)); } } */ for (Movie movie: originalMovieList) { filterableString1 = movie.getTitle(); filterableString2 = movie.getRating(); if (filterableString1.toLowerCase().contains(filterString)||filterableString2.toLowerCase().contains(filterString)) { // nlist.add(filterableString); nlist.add(movie); } } results.values = nlist; results.count = nlist.size(); return results; } @SuppressWarnings("unchecked") @Override protected void publishResults(CharSequence constraint, FilterResults results) { movieItems.clear(); movieItems.addAll((ArrayList<Movie>) results.values); notifyDataSetChanged(); } }; } } 

Y utilizar este método como este en su búsqueda Ver:

  @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); // Inflate menu to add items to action bar if it is present. inflater.inflate(R.menu.main, menu); SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); SearchView search = (SearchView) menu.findItem(R.id.action_search).getActionView(); search.setSearchableInfo(manager.getSearchableInfo(getComponentName())); search.setOnQueryTextListener(new SearchView.OnQueryTextListener() { @Override public boolean onQueryTextSubmit(String query) { return true; } @Override public boolean onQueryTextChange(String newText) { adapter.getFilter(getComponentName()).filter(newText); adapter.notifyDataSetChanged(); return false; } }); return true; } 

Por favor use este código:

  array111.add(new AshTable(test1, test2, test3, test4, test5, test6, test7, test8, test9, test10, test11, test12, test13, test14, test15, test16, test17, test18, test19, test20, test21, test22, test23, test24, test25, test26, test27, test28, test29, test30, test31, test32, test33, test34, test35, test36, test37, test38, test39, test40, test41, test42)); } } catch (JSONException e) { e.printStackTrace(); } final CustomListViewAdapter adapter = new CustomListViewAdapter(getActivity(), R.layout.home_list_view, array111); lstv11.setAdapter(adapter); inputSearch.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable arg0) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { if (YourClassName.this.adapter != null) ((YourAdapterClassName) YourClassName.this.adapter).getFilter().filter(arg0); } }); mSwipeRefreshLayout.setRefreshing(false); } } 

Y su clase de adaptador

Básicamente lo que tienes que hacer es comprobar cada valor en la lista para ver si cumple con los requisitos de filtro y, a continuación, agrega que a una lista temporal. Una vez que tenga una lista completa, intercambie la lista de temp en la lista de adaptadores de array, en su caso prod . Usted también tiene que dar cuenta de ningún filtro, o la recuperación de la lista completa, por lo que desea mantener una referencia a esa lista también. Todo lo que tienes que hacer es crear otra matriz y asignar una copia de la lista original a la lista de referencias. Todo esto podría parecer algo así:

 //Create reference list to keep track of complete list. ArrayList<AshTable> refList = new ArrayList<AshTable>(); public CustomListViewAdapter(Context context, int resource, ArrayList<AshTable> prod) { super(context, resource, prod); this.context=context; this.resource=resource; this.prod=prod; this.refList = prod; } //Filter method public void filter(String charText) { charText = charText.toLowerCase(Locale.getDefault()); if (charText.length() == 0) { //if there is no data to filter, replace complete list prod.clear(); prod.addAll(refList); } else { //Temp array to store values that meet filter requirements ArrayList<AshTable> tempTable = new ArrayList<AshTable>(); for(AshTable pro : prod){ //here you can add any other filter requirements //just iterate through each item and check it. if(pro.getPersonname().contains(charText)){ tempTable.add(pro); } } //put filtered data into arraylist prod.clear(); prod.addAll(tempTable); } notifyDataSetChanged(); }
