Question

我在Android市场上报告了一个我无法重新创建的错误。错误是

HOLA是用户输入的表格。我使用的代码是

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getLoc();
    setContentView(R.layout.notepad_list);
    db = new DBase(this);
    db.open();
    fillData();
    db.close();

}

和

private void fillData() {
    // Get all of the notes from the database and create the item list
    Cursor c = db.fetchData(loc);
    startManagingCursor(c);

    String[] from = new String[] { DBase.KEY_ONE, DBase.KEY_TWO };
    int[] to = new int[] { R.id.text1, R.id.text2 };

    // Now create an array adapter and set it to display using our row
    SimpleCursorAdapter notes = new SimpleCursorAdapter(this,
            R.layout.notes_row, c, from, to);
    setListAdapter(notes);

}

最后

public Cursor fetchData(String loc) {
    // TODO Auto-generated method stub

    return ourDatabase.query(loc, new String[] { KEY_ROWID, KEY_ONE, KEY_TWO },
            null, null, null, null, null);
}

loc是指向当前表的变量。任何想法为什么会这样？我尝试输入包括a的数据。和错误中提到的，但我无法获得FC。

编辑添加我的添加表代码

public long addTable(String loc) {
    // TODO Auto-generated method stub
    ourDatabase.execSQL("CREATE TABLE IF NOT EXISTS " + loc + " ("
            + KEY_ROWID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_2TBL
            + " TEXT NOT NULL, " + KEY_TWO + " TEXT NOT NULL, "
            + KEY_ONE + " TEXT NOT NULL);");
    ContentValues cv = new ContentValues();
    cv.put(KEY_2TBL, loc);
    return ourDatabase.insert(loc, null, cv);

}

我认为用户已输入“HOLA。”（带点）而非“HOLA”。这可能是app给FC的原因
