我怎样才能在Android的未读短信的数量？

How can I get the number of unread sms in android?

推荐答案

需要执行一个简单的查询短信的ContentProvider。以下是一个例子：

Need to execute a simple query to SMS ContentProvider. Here is a working example:

final Uri SMS_INBOX = Uri.parse("content://sms/inbox");

Cursor c = getContentResolver().query(SMS_INBOX, null, "read = 0", null, null);
int unreadMessagesCount = c.getCount();
c.deactivate();

您还需要READ_SMS权限：

You will also need the READ_SMS permission:

<uses-permission android:name="android.permission.READ_SMS" />

请记住，短信内容提供者是不实际的SDK的一部分，而这code不能保证在所有的过去，present和未来的设备。

Keep in mind that the SMS content provider isn't actually part of the SDK, and this code is not guaranteed to work on all past, present and future devices.
