我想實(shí)現(xiàn)getFilter()我的功能ListView，但每次我輸入的東西EditText我ListView就會(huì)消失。我的SetHelpRows檔案：public class SetHelpRows {    String name;    String id;    public String getName () {        return name;    }    public void setName (String name) {        this.name = name;    }    public String getID () {        return id;    }    public void setID (String id) {        this.id = id;    }    public SetHelpRows(String name, String id) {        super();        this.name = name;        this.id = id;    }}我的部分MainActivity文件：inputSearch = (EditText) findViewById(R.id.etSearch);dataList = (ListView) findViewById(R.id.lvFiles);for (int y=0; y<strNames.length;y++) {    name = strNamesOfAllah[y];    meaning = strMeaning[y];    rowsArray.add(new SetRows(R.drawable.icon, name, meaning));}adapter = new SetRowsCustomAdapter(MainActivity.this, R.layout.customlist, rowsArray);dataList.setAdapter(adapter);dataList.setClickable(true);inputSearch.addTextChangedListener(new TextWatcher() {    @Override    public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {        // When user changed the Text        //MainActivity.this.adapter.getFilter().filter(cs);        //String text = inputSearch.getText().toString().toLowerCase();        adapter.getFilter().filter(cs.toString().toLowerCase(Locale.US));    }    @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                             }});在中，LogCat我確實(shí)看到以下內(nèi)容：12-12 12:15:57.077: I/Before Filter(720): Before Filter12-12 12:15:57.106: I/prefix is !null or !0(720): prefix is !null or !012-12 12:15:57.216: I/publish result(720): publish result
