Question

我有问题从数据库中的数据中选择。我使用SQLite Browser创建了我的表，然后将数据库导入了工作室。我想从数据库中读取数据。这是数据库的初始化：

public static String DB_PATH            = "data/data/com.psm.app.hadis40_07/databases/";
public static String DB_NAME            = "hadis40_db";
public static String TABLE_LOCATION     = "hadis";

logcat提示符：

Caused by: android.database.sqlite.SQLiteException: no such table: hadis (code 1): , while compiling: SELECT  hadis_id,no_hadis,tajuk_hadis,hadis,terjemahan,tajuk_audio_hadis,audio_hadis,pengajaran_hadis,sebab_wurud_hadis FROM hadis

这是我称之为数据库的方法：

 public ArrayList<HashMap<String, String>> getHadisList() {
    //Open connection to read only
    //SQLiteDatabase db = dbHelperHadis.getReadableDatabase();
    String selectQuery =  "SELECT  " +
            Hadis.KEY_hadisID + "," +
            Hadis.KEY_noHadis + "," +
            Hadis.KEY_tajukHadis + "," +
            Hadis.KEY_hadis + "," +
            Hadis.KEY_terjemahan + "," +
            Hadis.KEY_tajukAudio + "," +
            Hadis.KEY_audioHadis + "," +
            Hadis.KEY_pengajaranHadis + "," +
            Hadis.KEY_sebabWurud +
            " FROM " + TABLE_LOCATION;

    SQLiteDatabase  db = SQLiteDatabase.openDatabase( DB_PATH + DB_NAME , null, SQLiteDatabase.OPEN_READWRITE);

    //Student student = new Student();
    ArrayList<HashMap<String, String>> hadisList = new ArrayList<HashMap<String, String>>();

    Cursor cursor = db.rawQuery(selectQuery, null);
    // looping through all rows and adding to list

    if (cursor.moveToFirst()) {
        do {
            HashMap<String, String> hadis = new HashMap<String, String>();
            hadis.put("id", cursor.getString(cursor.getColumnIndex(Hadis.KEY_hadisID)));
            hadis.put("name", cursor.getString(cursor.getColumnIndex(Hadis.KEY_noHadis)));
            hadisList.add(hadis);

        } while (cursor.moveToNext());
    }

    cursor.close();
    db.close();
    return hadisList;

}

任何人都可以帮助我吗？感谢

没有这样的表：hadis（代码1）
