我正在尝试使用 cursorAapter 将两个字符串绑定到 textView。但是，我似乎得到了资源未找到异常。我不明白为什么，因为它们都是 2 种字符串类型，而且我在程序的开头输入了一个条目，所以会有一些东西要显示。

我猜这条线是问题所在：

 text_modulecode.setText(c.getColumnIndex(database.KEY_MODULECODE));

columnIndex 很可能是一个 int，它被解释为一个 resourceId。这就是它搜索资源 ID 1（列索引）的原因。采用

....setText(String.valueOf(c.getColumnIndex(database.KEY_MODULECODE)));

确保您使用采用字符串的方法。
