Sqliteデータベーステーブルからデータを取得したいAndroidアプリケーションに取り組んでいます。
テーブルにデータが存在する場合でも、エラーが発生します。
コード:
public List<Mikats> getAllMikats() {
List<Mikats> contactList = new ArrayList<Mikats>();
// Select All Query
String selectQuery = "SELECT * FROM " + TABLE_NAME_2;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
//cursor.moveToFirst()
int rows=cursor.getCount();
if (rows>0) {
do {
Mikats mikat = new Mikats();
int mid=cursor.getInt(1);
String sqlectEventTitle="select * from "+ TABLE_NAME_1 +" where "+ KEY_MID+" = "+mid;
SQLiteDatabase db2 = this.getWritableDatabase();
Cursor cursor1=db2.rawQuery(sqlectEventTitle, null);
if(cursor1.moveToNext())
{
String Title=cursor1.getString(cursor1.getColumnIndex("EventTitle"));
mikat.setEventTitle(Title);
}
mikat.setEjamatID(Integer.parseInt(cursor.getString(0)));
mikat.setMikatID(Integer.parseInt(cursor.getString(1)));
mikat.setStartDate(cursor.getString(2));
mikat.setEndDate(cursor.getString(3));
mikat.setBlock(cursor.getString(4));
mikat.setFloor(cursor.getString(5));
mikat.setGate(cursor.getString(6));
String masjid=cursor.getString(7);
mikat.setMasjid(masjid);
mikat.setAutoID(Integer.parseInt(cursor.getString(8)));
mikat.setSeatNo(cursor.getString(9));
// Adding contact to list
contactList.add(mikat);
} while (cursor.moveToNext());
}
// return contact list
return contactList;
}
エラー行:
int mid=cursor.getInt(1);
