Android:IllegalStateException:无法从 CursorWindow 读取第 24929 行，第 0 列

Question

我需要有关此错误的帮助:

Fatal Exception: java.lang.IllegalStateException: Couldn't read row 24929, col 0 from CursorWindow. 
Make sure the Cursor is initialized correctly before accessing data from it

在这段代码中:

SQLiteDatabase db = getReadableDatabase();
Cursor res = db.rawQuery("select id from " + pTable, null);

if (res != null) {
    if (res.getCount() != 0) {
        res.moveToFirst();
        int id;
        while (!res.isAfterLast()) {
            id = res.getInt(res.getColumnIndex("id")); // <-- Error was here
            // ...
            res.moveToNext();
        }
    }
    res.close();
}

此代码有时有效，但当我有很多行(如 25k 行)时，我会收到此异常。是 Android 限制吗？

你能帮我吗？谢谢!

 public ArrayList<Model> Name(){
    ArrayList<Model> ModelList = new ArrayList<>();
    db = getWritableDatabase();
    Cursor c = db.rawQuery(" SELECT * FROM " + pTable,null );
    while (c.moveToNext()){
        String id = c.getString(0);
 return ModelList;
}
