Question

有没有办法可以搜索包含自定义类的列表？另外，如果可能的话，我想添加语音搜索。

声音等级

            private int _id;
        private String _productname;
       private String _extra;
        private int _image;

        public SoundListed() {

        }

        public SoundListed(int id, String productname, String extra, int image) {
            this._id = id;
            this._productname = productname;
            this._extra = extra;
            this._image=image;
        }

        public SoundListed( String productname, String extra, int image) {
            this._productname = productname;
            this._extra = extra;
            this._image=image;
        }
        public void setID(int id) {
            this._id = id;
        }

        public int getID() {
            return this._id;
        }
        public int getImage(){return this._image;}

        public void setProductName(String productname) {
            this._productname = productname;
        }

        public String getProductName() {
            return this._productname;
        }

        public void setExtra(String extra) {
            this._extra = extra;
        }

        public String getExtra() {
            return this._extra;
        }


And the adapter:

    public class soundAdapter extends ArrayAdapter{
    private Context context;
    private List <SoundListed> listSounds;
    public soundAdapter(Context context, List<SoundListed> friends) {
        super(context, R.layout.customrow, friends);
        this.context=context;
        this.listSounds=friends;
    }


    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if(convertView==null){
            LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            convertView=inflater.inflate(R.layout.soundrow,null);
        }
        SoundListed s = listSounds.get(position);
        TextView soundName = (TextView)convertView.findViewById(R.id.nameOfFile);
        TextView soundExtras = (TextView)convertView.findViewById(R.id.extraText);
        soundName.setText(s.getProductName());
        soundExtras.setText(s.getExtra());
        return convertView;
    }
}

简短说明 - 这是一种音板，我想用户能够使用soundExtras和soundName搜索（我使用操作栏搜索小部件来搜索列表）

提前致谢！

是的可能

       searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {

        @Override
        public boolean onQueryTextSubmit(String search) {
            // TODO Auto-generated method stub

            return false;
        }

        @Override
        public boolean onQueryTextChange(String search) {
            // TODO Auto-generated method stub
            //if you use ArrayAdapter
           // MainActivity.this.soundadapter.getFilter().filter(search);    
            //custom adapter you need to add custom filter                
              MainActivity.this.soundadapter.filter(search);
            return true;
        }
    });

你的soundAdapter中的

private Context context;
private List <SoundListed> listSounds;
 //you need temp list of data for your feature use
private List <SoundListed> listSoundsTemp;

public soundAdapter(Context context, List<SoundListed> friends) {
    super(context, R.layout.customrow, friends);
    this.context=context;
    this.listSounds=friends;
    this.listSoundsTemp=friends;
}

void filter(String search)
{       
   if(search=="")
       listSounds = listSoundsTemp;
   else
   {
      List <String> listClone = new ArrayList<String>(); 
        for (SoundListed list: listSoundsTemp) {
            if(s.getProductName().matches("(?i)("+search+").*") || s.getExtra().matches("(?i)("+search+").*")){
               listClone.add(list);
           }
        }
      listSounds= listClone;
   }
   notifyDataSetChanged();
}

EditText inputSearch;//your search box 
     inputSearch.addTextChangedListener(new TextWatcher() {

                @Override
                public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
                    // When user changed the Text
                     adapter.getFilter().filter(cs);    
                     //Use your adapter object name instead adapter
                }

                @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                          
                }
        });
