Q:Trying to put a search functionality in my application

Q:试图在我的应用程序中设置搜索功能

Hi, guys! First of all, I'm newbie! I'm trying to create a search functionality (Search BY CITY) in my application. But something is wrong! It don't work!

The error message is: 'The method filter(String) is undefined for the type BinderData'

                adapter.filter(text);

Could someone help me in details? I included the "TextWatcher" function in my main activity (WeatherActivity).

This is my code:

WeatherActivity

public class WeatherActivity extends Activity {

// XML node keys
static final String KEY_TAG = "weatherdata"; // parent node
static final String KEY_ID = "id";
static final String KEY_CITY = "city";
static final String KEY_TEMP_C = "tempc";
static final String KEY_TEMP_F = "tempf";
static final String KEY_CONDN = "condition";
static final String KEY_SPEED = "windspeed";
static final String KEY_ICON = "icon";
EditText editsearch;
// List items 
ListView list;
BinderData adapter = null;
List<HashMap<String,String>> weatherDataCollection;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

        Document doc = docBuilder.parse (getAssets().open("weatherdata.xml"));










        weatherDataCollection = new ArrayList<HashMap<String,String>>();

        // normalize text representation
        doc.getDocumentElement ().normalize ();

        NodeList weatherList = doc.getElementsByTagName("weatherdata");

        HashMap<String,String> map = null;

        for (int i = 0; i < weatherList.getLength(); i++) {

               map = new HashMap<String,String>(); 

               Node firstWeatherNode = weatherList.item(i);

                if(firstWeatherNode.getNodeType() == Node.ELEMENT_NODE){

嗨,伙计们!首先,我是新手!我试图在我的应用程序中创建一个搜索功能(按城市搜索)。但有些事是错的!它不工作!

错误信息:“该方法滤波(字符串)是未定义的类型的binderdata”

                adapter.filter(text);

有人能帮我详细吗?我在我的主要活动包括“textwatcher”功能(weatheractivity)。
