이게 어댑터 뷰 소스이고 

mJsonListView = (ListView) findViewById(R.id.list);

 

mJsonList = new ArrayList<JsonBean>();

mAdapter = new JsonListAdapter(this, R.layout.jong_vetlist, mJsonList);

 

mJsonListView.setTextFilterEnabled(true);

mJsonListView.setAdapter(mAdapter);

searchEdit = (EditText) findViewById(R.id.search_edit);

searchBtn = (Button) findViewById(R.id.search_btn);

searchBtn.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
String text=searchEdit.getText().toString();
Log.i("hey!!!!", text);
mAdapter.getFilter().filter(text);
}
});

이건 액티비티에서 리스트뷰를 갱신하는 형태 입니다.

 

이미 리스트뷰에 항목들이 띄어져있는데

지금 검색한 것을 검색버튼을 누르면 필터를 이용해서 리스트뷰에 갱신을 하고 싶은데 갱신이 되지 않습니다.

어떻게 해야될지 감이안잡히네요 ㅠㅠ
