android 通话列表

在android通话列表中，如果单纯的显示出来，会将很多同名通话记录也展示出来。像这种情况我们一般是将同名的通话记录group起来；既确保了速度也美观人性化。

要实现这个功能很简单，默认的android Cursor.query方法没有group这个参数；我们只能在原有基础上进行修改。

如下：cursor = cr.query(CallLog.Calls.CONTENT_URI,
new String[]{CallLog.Calls.NUMBER,CallLog.Calls.CACHED_NAME,CallLog.Calls.TYPE,CallLog.Calls.DATE},
"1=1) group by "+CallLog.Calls.NUMBER+" order by " +CallLog.Calls.DATE+ " DESC"+" -- (",
null,
CallLog.Calls.DATE);

在这里采用了一个投机取巧的方法，不过功能可以实现。

具体不多说了，直接粘代码：

AppCallMessage.java

listview.setAdapter(adapter);

}
