使用编辑文本过滤带有文本和图像的自定义列表视图

Question

我使用MyCustom适配器在列表视图中填充文本和图像，它正确填充图像和文本但是 当我使用edittext过滤该列表视图时，它不会过滤。 请给我一些有用的代码和建议来解决这个问题

我的漏洞代码如下。

private ArrayList<String> friends;
private ArrayList<Bitmap> images;
ArrayAdapter<String> adapter;
SimpleCursorAdapter filterAdapter;
MyCustomAdapter dataAdapter = null;

ListView sp_make;
ImageView iv;


EditText etext;

// A good practice is to define database field names as constants
private static final String TABLE_NAME = "BREEDS";
private static final String BIKE_ID = "_id";
private static final String BIKE_MAKE = "Breeds";
private static final String AKCGROUP = "AKCGroup";
private static final String IMAGE = "image";

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

    friends = new ArrayList<String>();
    images = new ArrayList<Bitmap>();

    BikeHelper dbOpenHelper = new BikeHelper(this, DB_NAME);
    database = dbOpenHelper.openDataBase();

    sp_make = (ListView) findViewById(R.id.listView1);
    iv = (ImageView) findViewById(R.id.list_image);

    fillFreinds();
    fillFreindsImage();

    dataAdapter = new MyCustomAdapter(this, R.layout.list_layout, friends);
    dataAdapter.setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
    sp_make.setAdapter(dataAdapter);



    sp_make.setFastScrollEnabled(true);
    sp_make.setTextFilterEnabled(true);


    etext = (EditText) findViewById(R.id.editText1);

    etext.addTextChangedListener(new TextWatcher() {

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


        }

        @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
        }
    });





    sp_make.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> listView, View view,
                int position, long id) {
            // Get the cursor, positioned to the corresponding row in the
            // result set
            Cursor cursor = (Cursor) listView.getItemAtPosition(position);
            // Get the state's capital from this row in the database.
            final String HorseCode = cursor.getString(cursor
                    .getColumnIndexOrThrow("DOG_ID"));

            // Chp.setid(HorseCode);
            // Intent signuplist = new Intent(SignupList.this,
            // CheckProfile.class);
            // startActivity(signuplist);

        }
    });

}

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

private void fillFreinds() {

    Cursor friendCursor = database.query(TABLE_NAME,
            new String[] { BIKE_MAKE }, null, null, null, null, BIKE_MAKE);
    friendCursor.moveToFirst();
    if (!friendCursor.isAfterLast()) {
        do {
            String name = friendCursor.getString(0);
            friends.add(name);
        } while (friendCursor.moveToNext());
    }
    friendCursor.close();
}

private void fillFreindsImage() {

    Cursor friendCursor = database.query(TABLE_NAME,
            new String[] { IMAGE }, null, null, null, null, null);
    friendCursor.moveToFirst();
    if (!friendCursor.isAfterLast()) {
        do {
            String name = friendCursor.getString(0);
            // System.out.println("image name byte value==="+name);

            byte[] decodedString = Base64.decode(name, Base64.DEFAULT);
            Bitmap decodedByte = BitmapFactory.decodeByteArray(
                    decodedString, 0, decodedString.length);

            images.add(decodedByte);

            System.out.println("image name byte value===" + decodedByte);

        } while (friendCursor.moveToNext());
