我一直在试图实现一个简单的搜索listview，我已经能够使用排序填充，但都没有效果，直到日期。感谢@Dhaval Patel谁一直在迎接帮助。但我现在遇到的问题是，当我搜索时，的ListView拒绝改变内容从而使他们的搜索程序中的使用BaseAdapter的ListView搜索功能不填充搜索列表
下面无用的是我的代码：
public class MainActivity extends Activity {
private ListView mList;
private List<Movie> movieList = new ArrayList<Movie>();
EditText inputSearch;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(R.layout.activity_main);
mList = (ListView) findViewById(R.id.list);
inputSearch = (EditText) findViewById(R.id.inputSearch);
adapter = new CustomListAdapter(this, movieList);
mList.setAdapter(adapter);
//SEARCH TEXTCHANGE
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs.toString());
//FLAGS Cannot resolve method 'getFilter()' here
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable arg0) {
// TODO Auto-generated method stub
}
});
}
}
而且这是代码在我的CustomListAdapter类
public class CustomListAdapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<Movie> movieItems;
private String[] bgColors;
private List<String>originalData = null;
private List<String>filteredData = null;
private ItemFilter mFilter = new ItemFilter();
ImageLoader imageLoader = MyApplication.getInstance().getImageLoader();
public CustomListAdapter(Activity activity, List<Movie> movieItems) {
this.activity = activity;
this.movieItems = movieItems;
bgColors = activity.getApplicationContext().getResources().getStringArray(R.array.movie_serial_bg);
}
@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_image, null);
if (imageLoader == null)
imageLoader = MyApplication.getInstance().getImageLoader();
NetworkImageView thumbNail = (NetworkImageView) convertView.findViewById(R.id.thumbnail);
TextView serial = (TextView) convertView.findViewById(R.id.serial);
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);
// 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("Rating: " + String.valueOf(m.getRating()));
// genre
String genreStr = "";
for (String str : m.getGenre()) {
genreStr += str + ", ";
}
genreStr = genreStr.length() > 0 ? genreStr.substring(0,
genreStr.length() - 2) : genreStr;
genre.setText(genreStr);
// release year
year.setText(String.valueOf(m.getYear()));
String color = bgColors[position % bgColors.length];
serial.setBackgroundColor(Color.parseColor(color));
return convertView;
}
public Filter getFilter() {
return mFilter;
}
private class ItemFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
String filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
final List<String> list = originalData;
int count = list.size();
final ArrayList<String> nlist = new ArrayList<String>(count);
String filterableString ;
for (int i = 0; i < count; i++) {
filterableString = list.get(i);
if (filterableString.toLowerCase().contains(filterString)) {
nlist.add(filterableString);
}
}
results.values = nlist;
results.count = nlist.size();
return results;
}
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredData = (ArrayList<String>) results.values;
notifyDataSetChanged();
}
}
}
所以有人可以告诉我什么我不正确。 在此先感谢
如果你使用Filter类，我确定我可以很容易地解决你的问题，请等待，当我可以找到它更容易使用过滤器比自己做。 – Nanoc
我能解决这个问题，但注意到我在这里发布的另一个问题http://stackoverflow.com/questions/33529720/can-not-reload-listview-content-after-implementing-filterable-interface-on-my -cu –
