在Android中获取未接来电，短信和邮件

Question

我想知道如何检索未接来电，短信和电子邮件。

假设我们为每个示例获得了3个文本视图：

private TextView mMissedCallsCount;
private TextView mLastMissedCallContactName;
private TextView mLastMissedCallContactNumber;

private TextView mUnreadedSMSCount;
private TextView mLastUnreadedSMSContactName; //or number
private TextView mLastUnreadedSMSContent;

private TextView mUnreadedEmailsCount;
private TextView mLastUnreadedEmailFrom; //contact
private TextView mLastUnreadedEmailContent; 

有人会表现出一种获取所需内容的简单方法吗？
