The bind value显然是指插入到query()中的所选内容的selectionArgs。如果这样的selectionArgs值为null，则会得到以下结果。

@Gray和@pjv响应是了解导致此错误的问题的关键所在。你必须小心选择和selectionArgs匹配，如果你传递selection = null和selectionArgs = something，你也会得到这个错误！:)谢谢！

这与问题并不完全相关，但我在argument containted a dash (-) at the beginning上遇到了类似的问题。这是导致问题的原因。
所以我就像这样避开了争论
return mDatabase.query(table_name,
null,
column_name + "=?",
new String[]{"\\" + argument},
null,
null,
null);这为我解决了问题。
