私はかなり詳細に調べましたが、同様の問題を見つけることはできません。
簡単に言えば、特定の日付に入力されたデータベース エントリを取得しようとしています。
これは私が持っているものです
Calendar calendar = Calendar.getInstance();
String dateAccessed = (calendar.get(Calendar.DAY_OF_MONTH) + "/" + (calendar.get(Calendar.MONTH)+1) + "/" + calendar.get(Calendar.YEAR));
HashMap<String, String> queryValues = new HashMap<String, String>();
queryValues.put("diaryName", valMealName);
queryValues.put("diaryDate", dateAccessed);
queryValues.put("diaryNumber", Long.toString(carbsValue));
controller.insertDiary(queryValues);
次のようにエントリを保存します
public void insertDiary(HashMap<String, String> queryValues) {
SQLiteDatabase database = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("diaryName", queryValues.get("diaryName"));
values.put("diaryDate", queryValues.get("diaryDate"));
values.put("diaryNumber", queryValues.get("diaryNumber"));
database.insert("diarys", null, values);
database.close();
}
検索/ LIKE クエリなしで通常の ListView にデータを入力できるため、これがうまく保存されていることはわかっています。
これを行うには、DBController クラスで次のことを試みています
public ArrayList<HashMap<String, String>> searchByDate() {
ArrayList<HashMap<String, String>> wordList;
wordList = new ArrayList<HashMap<String, String>>();
SQLiteDatabase database = this.getReadableDatabase();
String selectQuery = "SELECT * FROM diarys";
Cursor cursor = database.query(selectQuery, new String[] { "diaryId",
"diaryName", "diaryDate", "diaryNumber" }, "diaryDate LIKE '"
+ dateAccessed + "%'", null, null, null, null);
if (cursor.moveToFirst()) {
do {
HashMap<String, String> map = new HashMap<String, String>();
map.put("diaryId", cursor.getString(0));
map.put("diaryName", cursor.getString(1));
map.put("diaryDate", cursor.getString(2));
map.put("diaryNumber", cursor.getString(3));
wordList.add(map);
} while (cursor.moveToNext());
}
return wordList;
}
に続く
ArrayList<HashMap<String, String>> diaryList = controller
.searchByDate();
ListAdapter adapter = new SimpleAdapter(FoodDiary.this, diaryList,
R.layout.view_diary_entry, new String[] { "diaryId",
"diaryName", "diaryDate", "diaryNumber" }, new int[] {
R.id.diaryId, R.id.diaryName, R.id.diaryDate,
R.id.diaryNumber });
setListAdapter(adapter);
私のアクティビティクラスでは
そして、これは私のエラーログです

私はポイントを得るためにいくつかのチュートリアルに従ったので、私が私の深さから外れていると言ってもかなり安全です.
どんな助けでも大歓迎です
