android - Android の CustomArrayAdapter でフィルター処理する

Question

私はAndroidが初めてで、ListViewに検索機能を追加することに関するいくつかのチュートリアルに従いましたが、私の場合は機能していません。私のコードで何が間違っているのか誰か教えてください。

これが私のコードです：

アクティビティ.java

public class SendMoney extends Activity {
    private ListView lvContacts;
    private EditText etSearch;
    private ContactListAdapter mAdapter;
    private String[] stockArr, stockArr1, stockArr2;
    private Intent i;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_send_money);

        initObjects();

        ArrayList<String> phoneContactList = new ArrayList<String>();
        ArrayList<String> ContactImage = new ArrayList<String>();
        ArrayList<String> PhoneNumber = new ArrayList<String>();

        ContentResolver cr = getContentResolver();
        Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

        if (cur.getCount() > 0) {
          while (cur.moveToNext()) {
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            String img = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.PHOTO_THUMBNAIL_URI));

            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
              // This inner cursor is for contacts that have multiple numbers.
              Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);
              while (pCur.moveToNext()) {
                String pnumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));

                ContactImage.add(img);
                phoneContactList.add(name);
                PhoneNumber.add(pnumber);

                Log.i("Contact List", pnumber);
              }
              pCur.close();
            }
          }

          Collections.sort(phoneContactList);
          int cnt = phoneContactList.size(); // Count of contacts

          // Convert ArrayList<String> to String[] START

          // Contacts Name
          stockArr = new String[phoneContactList.size()];
          stockArr = phoneContactList.toArray(stockArr);

          // Contacts Photo
          stockArr1 = new String[ContactImage.size()];
          stockArr1 = ContactImage.toArray(stockArr1);

          // Contacts Number
          stockArr2 = new String[PhoneNumber.size()];
          stockArr2 = PhoneNumber.toArray(stockArr2);

          // Convert ArrayList<String> to String[] END

          mAdapter = new ContactListAdapter(getApplicationContext(), R.layout.banks_listview_layout, stockArr, stockArr1);
          lvContacts.setAdapter(mAdapter);

        }
        cur.close();

        lvContacts.setTextFilterEnabled(true);
        lvContacts.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> adapter, View view, int position, long id) {             
                i = new Intent(SendMoney.this, SendMoneyForm.class);
                i.putExtra("contact_name", stockArr[position]);
                i.putExtra("contact_image", stockArr1[position]);
                i.putExtra("contact_number", stockArr2[position]);
                startActivity(i);
            }
        });


        //***************** SEARCH START ***********************

        etSearch.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
                // When user changed the Text
                mAdapter.getFilter().filter(cs.toString());
            }

            @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                          
            }
        });

        //***************** SEARCH END ***********************
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.send_money, menu);
        return true;
    }

    private void initObjects(){
        lvContacts = (ListView)findViewById(R.id.lvContacts);
        etSearch   = (EditText)findViewById(R.id.etSearch);
    }

私のカスタム アレイ アダプター

public class ContactListAdapter extends ArrayAdapter<String> {
    private LayoutInflater mInflater;
    private String[] mStrings;
    private String[] mIcons;
    private int mViewResourceId;

    public ContactListAdapter(Context ctx, int resource,
            String[] option, String[] icons) {
        super(ctx, resource, option);

        mInflater = (LayoutInflater)ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mStrings = option;
        mIcons   = icons;    
        mViewResourceId = resource;

    }

     @Override
        public int getCount() {
            return mStrings.length;
        }

        @Override
        public String getItem(int position) {
            return mStrings[position];
        }

        @Override
        public long getItemId(int position) {
            return position;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            convertView = mInflater.inflate(mViewResourceId, null);

            ImageView iv = (ImageView)convertView.findViewById(R.id.ivBankIcon);
            if(mIcons[position]==null) {
                iv.setImageResource(R.drawable.default_picture);
            } else {
                iv.setImageURI(Uri.parse(mIcons[position]));
                Log.d("LALA", mIcons[position]);
            }

            TextView tv = (TextView)convertView.findViewById(R.id.tvBankName);
            tv.setText(mStrings[position]);

            return convertView;
        }
}

前もって感謝します！
