我正在尝试在其他设备上运行我的应用程序，但它在打开时崩溃但是它完全适用于其他设备我不知道为什么它会给我这个错误

Caused by: java.lang.IllegalStateException: Couldn't read row 0, col 8 from CursorWindow.  Make sure the Cursor is initialized correctly before accessing data from it.

作为此行中的错误

        if (data.getInt(8)== 1) {
            multipleLogIn.setChecked(true);
        }else {
            multipleLogIn.setChecked(false);
        }if (data.getInt(9)== 1) {
            x = 1;
            passCode.setChecked(true);


        }else
            passCode.setChecked(false);

Answer 1

尝试更改以下内容：

public Cursor getListContents(String _ID) {
    SQLiteDatabase db = this.getWritableDatabase(); 
    Cursor data = db.rawQuery("SELECT * FROM " + TABLE_NAME + _ID, null);
    return data;
}

为：

public Cursor getListContents(String _ID) { // Parameter unused, could remove.
    SQLiteDatabase db = this.getWritableDatabase(); 
    Cursor data = db.rawQuery("SELECT * FROM " + TABLE_NAME, null); // REMOVED _ID
    return data;
}

您似乎无意中在选择查询中创建了错误的表名。
