フィルタリング後にリストビューに適切な結果が表示されない

Question

アダプタークラスでフィルターメソッドを使用して行った検索ビューがあるので、フルネームまたは検索番号を入力するたびに、表示されない結果が表示されますListView最初の文字を入力するか番号を表示するとその結果が表示されますので、フルネームまたは数字を入力するたびにデバッグを行い、すべてのコードが正しいことがわかりました。

public class AdmitPatientAdapter extends BaseAdapter { 

    private Activity activity; 
    ArrayList<HashMap<String, String>> data; 
    ArrayList<HashMap<String, String>> TempArrList = new ArrayList<>();

      TempArrList.addAll(data); 

     } else { 
      for (int i = 0; i < data.size(); i++) { 
       HashMap<String, String> tMap; 
       tMap = data.get(i);

使用このコード::

あなたのクラスで

editsearch.addTextChangedListener(new TextWatcher() { 

@Override 
public void afterTextChanged(Editable arg0) { 
// TODO Auto-generated method stub 
String text = editsearch.getText().toString().toLowerCase(Locale.getDefault()); 
adapter.filter(text); 
} 

@Override 
public void beforeTextChanged(CharSequence arg0, int arg1, 
int arg2, int arg3) { 
// TODO Auto-generated method stub 
} 

@Override 
public void onTextChanged(CharSequence arg0, int arg1, int arg2, 
int arg3) { 
// TODO Auto-generated method stub 
} 
});
