本文整理了Java中android.database.Cursor.getColumnIndexOrThrow()方法的一些代码示例，展示了Cursor.getColumnIndexOrThrow()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Cursor.getColumnIndexOrThrow()方法的具体详情如下：
包路径：android.database.Cursor
类名称：Cursor
方法名：getColumnIndexOrThrow

Cursor.getColumnIndexOrThrow介绍

[英]Returns the zero-based index for the given column name, or throws IllegalArgumentException if the column doesn't exist. If you're not sure if a column will exist or not use #getColumnIndex(String) and check for -1, which is more efficient than catching the exceptions.
[中]返回给定列名的从零开始的索引，如果该列不存在，则抛出IllegalArgumentException。如果不确定列是否存在，请使用#getColumnIndex（String）并检查-1，这比捕获异常更有效。
