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：

[java]

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:

[java]

public class PortaitArrayAdapter extends ArrayAdapter {

private final Context context;

private final String[][] values;

private List imagenes = null;

private LayoutInflater mInflater;

public ImageLoader imageLoader;

public PortaitArrayAdapter(Context context, String[][] values) {

super(context, R.layout.gallery_row);

this.context = context;

this.values = values;

mInflater = (LayoutInflater) context

.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

imagenes = new ArrayList();

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);

}

@Override

public int getCount (){

return this.values.length;

}

@Override

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

ViewHolder holder;

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);

} else {

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);

Bitmap bmp;

Log.v("Position --> ",String.valueOf(position));

try {

byte b[] = imagenes.get(position).getImageData();

if (b != null) {

bmp = BitmapFactory.decodeByteArray(b, 0, b.length);

if (bmp != null) holder.imageView.setImageBitmap(bmp);

} else {
