こんにちは、StaleDataException というエラーが発生しています。このエラーは、リストのフィルター処理に使用している編集テキストが空白であるか、「いいね! 条件」に一致する場合に発生し続けます。カーソルを使用して新しい行を取得しようとしていますが、まだ答えが得られていないので、これに対する助けは素晴らしいでしょうか?

 public class CBFilter extends ListActivity {

EditText Filter;
ListView RecipeNames;
Cursor cursor, c;
CBListAdapter adapter;
CBDataBaseHelper data, data2;

String[] from = { CBDataBaseHelper.KEY_NAME};
int[] to = { R.id.rowText};

public static final String TAG = "Error";

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

//FileInputStream in;//= openFileInput("//STEFAN-PC/Users/stefan/Desktop/Uni Work/Image.jpg");
RecipeNames = (ListView) findViewById(android.R.id.list);
RecipeNames.setTextFilterEnabled(true);
RecipeText = (TextView) findViewById(R.id.recipeText);
Filter = (EditText) findViewById(R.id.search_box);

//adapter = new SimpleCursorAdapter (this, 0, cursor, null, null);
//image = (ImageView) findViewById(R.id.RecipeImage);
data = new CBDataBaseHelper(this);
data.open();
cursor = data.query();
startManagingCursor(cursor);
adapter = new CBListAdapter(this, 0, cursor, from, to);
RecipeNames.setAdapter(adapter);
adapter.notifyDataSetChanged();

Filter.addTextChangedListener(new TextWatcher() {
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        try{

    filteradapter.setFilterQueryProvider(filterQueryProvider);

    //RecipeNames.setAdapter(filteradapter);
