这可能是一个愚蠢的问题，我是一个有点小白的。我正在读这篇文章：如何访问通话记录Android版

This may be a silly question, I'm a bit of a noob. I was reading this post: How do i access call log for android?

和在的code底部的答案，他们有这样一行：

and in the answer at the bottom of the code they have this line:

int type = Integer.parseInt(c.getString(c.getColumnIndex(CallLog.Calls.TYPE)));// for call type, Incoming or out going

我有点困惑，如何呼叫类型存储，是它作为一个字符串或整数？ 的code所示行让我觉得它保存为一个数字，但在字符串格式。谁能解释这样对我？

I'm a little confused as to how the call type is stored, is it as a string or as an integer? The line of code shown makes me think its saved as a number, but in string format. Can anyone explain this to me?

谢谢， 马特

推荐答案

该类型存储为整数。这是我如何获得新的未接来电列表：

The type is stored as integer. This is how I get a list of new missed calls:

cursor = cr.query(Uri.parse("content://call_log/calls"), null, "type = 3 AND new = 1", null, "date DESC");

当然使用CallLog.Calls.MISSED_TYPE中，INCOMING_TYPE和OUTGOING_TYPE恒效果会更好。

Of course using the CallLog.Calls.MISSED_TYPE, INCOMING_TYPE and OUTGOING_TYPE constant would be better.
