出门在外也不愁使用 arrayadapter 来 filter 一个 listview
我使用 arrayadapter 来 filter 一个 listview。Arraydapter 的参数是一个String[][]。但是没有成功，必须要重写 Filter interface吗？要是这样的话，如何重写呢？
filter 数组的每一个位置：
galleryValues[0][0] -& "tiulo" [0][1] -& "desc" [0][2] -& "etc"
lstContinente = (ListView)findViewById(R.id.list);
lstContinente.setTextFilterEnabled(true);
adapter = new PortaitArrayAdapter(cx,galleryValues);
lstContinente.setAdapter(adapter);
ed_busqueda.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
// TODO Auto-generated method stub
public void onTextChanged(CharSequence s, int start, int before, int count) {
adapter.getFilter().filter(s.toString());
adapter.notifyDataSetChanged();
The adapter code:
public class PortaitArrayAdapter extends ArrayAdapter&String& {
private final C
private final String[][]
private List&Imagen& imagenes =
private LayoutInflater mI
public ImageLoader imageL
public PortaitArrayAdapter(Context context, String[][] values) {
super(context, R.layout.gallery_row);
this.context =
this.values =
mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imagenes = new ArrayList&Imagen&();
for (int i = 0; i & 20; i++) imagenes.add(new Imagen());
Bitmap def = BitmapFactory.decodeResource(this.context.getResources(),R.drawable.ic_launcher);
imageLoader=new ImageLoader(this.context,def, imagenes);
public int getCount (){
return this.values.
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
holder = new ViewHolder();
convertView =
mInflater.inflate(R.layout.gallery_row, parent, false);
holder.txtTitulo = (TextView) convertView.findViewById(R.id.txt_gallery_titulo);
holder.txtDesc = (TextView) convertView.findViewById(R.id.txt_gallery_desc);
holder.txtFecha = (TextView) convertView.findViewById(R.id.txt_gallery_fecha);
holder.txtEst = (TextView) convertView.findViewById(R.id.txt_gallery_est);
holder.imageView
= (ImageView)convertView.findViewById(R.id.lst_img_gallery);
convertView.setTag(holder);
holder = (ViewHolder) convertView.getTag();
/*LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.gallery_row, parent, false);*/
//ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);
Log.v("Position --& ",String.valueOf(position));
byte b[] = imagenes.get(position).getImageData();
if (b != null) {
bmp = BitmapFactory.decodeByteArray(b, 0, b.length);
if (bmp != null) holder.imageView.setImageBitmap(bmp);
String urlBase = galleryValues[position][0].substring(0, galleryValues[position][0].lastIndexOf("/")+1);
String urlToEncode = galleryValues[position][0].substring(galleryValues[position][0].lastIndexOf("/")+1, galleryValues[position][0].length());
urlToEncode = URLEncoder.encode(urlToEncode,"UTF-8");
String url = urlBase.concat(urlToEncode);
url = url.replace("+", "%20");
Log.v("UrlFinal --& ",url);
imageLoader.DisplayImage(String.valueOf(position),url,act,holder.imageView, position,null);
} catch (Exception e) {
Log.e(this.getClass().getName(),"Exception en pos = " + position + " error:" + e.getMessage());
e.printStackTrace();
holder.txtTitulo.setText(galleryValues[position][1] + ", " + galleryValues[position][2]);
String[] dates = galleryValues[position][4].split("/");
String date = dates [1] + "/" + dates[0] + "/" + dates[2];
Date d1 = new Date(date);
DateFormat df = DateFormat.getDateInstance(DateFormat.LONG);
holder.txtDesc.setText(galleryValues[position][3]);
holder.txtFecha.setText(df.format(d1));
holder.txtEst.setText(getText(R.string.num_fotos_gallery) + galleryValues[position][5] + " - " + getText(R.string.num_videos_gallery) + galleryValues[position][6] + " - " + getText(R.string.num_exp_gallery) + galleryValues[position][7]);
return convertV
private static class ViewHolder {
TextView txtT
TextView txtD
TextView txtF
TextView txtE
ImageView imageV

把字符串数组放在 ArrayList 中，然后把它传递到 Adapter。使用下面的代码或者用 String[]更改下面的代码。
需要在 Adapter 类中实现 Filterable ，重写 getFilter()。
参考下面的代码关于 Filtering custom Adapter.
public class ListFilterActivity extends ListActivity {
private List&String& list = new ArrayList&String&();
List&String& mOriginalV
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final MyAdapter adapter = new MyAdapter(this, getModel());
setListAdapter(adapter);
EditText filterEditText = (EditText) findViewById(R.id.filterText);
// Add Text Change Listener to EditText
filterEditText.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
// Call back the Adapter with current character to Filter
adapter.getFilter().filter(s.toString());
public void beforeTextChanged(CharSequence s, int start, int count,int after) {
public void afterTextChanged(Editable s) {
private List&String& getModel() {
list.add("Linux");
list.add("Windows7");
list.add("Suse");
list.add("Eclipse");
list.add("Ubuntu");
list.add("Solaris");
list.add("Android");
list.add("iPhone");
list.add("Windows XP");
// Adapter Class
public class MyAdapter extends BaseAdapter implements Filterable {
List&String& arrayL
List&String& mOriginalV // Original Values
public MyAdapter(Context context, List&String& arrayList) {
this.arrayList = arrayL
inflater = LayoutInflater.from(context);
public int getCount() {
return arrayList.size();
public Object getItem(int position) {
public long getItemId(int position) {
private class ViewHolder {
TextView textV
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder =
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.row, null);
holder.textView = (TextView) convertView
.findViewById(R.id.textview);
convertView.setTag(holder);
holder = (ViewHolder) convertView.getTag();
holder.textView.setText(arrayList.get(position));
return convertV
public Filter getFilter() {
Filter filter = new Filter() {
@SuppressWarnings("unchecked")
protected void publishResults(CharSequence constraint,FilterResults results) {
arrayList = (List&String&) results. // has the filtered values
notifyDataSetChanged();
// notifies the data with new filtered values
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
// Holds the results of a filtering operation in values
List&String& FilteredArrList = new ArrayList&String&();
if (mOriginalValues == null) {
mOriginalValues = new ArrayList&String&(arrayList); // saves the original data in mOriginalValues
If constraint(CharSequence that is received) is null returns the mOriginalValues(Original) values
else does the Filtering and returns FilteredArrList(Filtered)
if (constraint == null || constraint.length() == 0) {
// set the Original result to return
results.count = mOriginalValues.size();
results.values = mOriginalV
constraint = constraint.toString().toLowerCase();
for (int i = 0; i & mOriginalValues.size(); i++) {
String data = mOriginalValues.get(i);
if (data.toLowerCase().startsWith(constraint.toString())) {
FilteredArrList.add(data);
// set the Filtered result to return
results.count = FilteredArrList.size();
results.values = FilteredArrL
