Android开发之通话记录

本文主要实现类似iPhone通话记录效果，即相邻通话如果通话号码相同、通话类型（呼入、呼出、未接）相同、间隔时间（某一阈值范围内），则将其归为一条记录，否则，将其分别显示。首先获取通话记录必须添加一下权限：

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

然后通过一下代码获取通话记录：

Cursor cursor = context.getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null);
           

然后须通过遍历通话记录，按照显示规则进行显示，在此需了解Cursor的相关知识：cursor.moveToFirst表示移动至当前记录的第一条，cursor.moveToNext表示当前记录的下一条记录，cursor.moveToPrevious表示当前记录的上一条记录，cursor.moveToLast表示当前记录的最后一条记录，一般moveToFirst和moveToNext、moveToPrevious和moveToLast配套使用。随后我们进行通话记录显示：

private void getCallRecord() {
	SimpleDateFormat sfd = new SimpleDateFormat("yyyy-MM-dd"); 
	Cursor cursor = context.getContentResolver().query(CallLog.Calls.CONTENT_URI, null, null, null, null);
	int i=0;
	if(cursor.moveToLast()){
		String prenumber=cursor.getString(cursor.getColumnIndex(Calls.NUMBER));
		int type = TypeDecision(Integer.parseInt(cursor.getString(cursor.getColumnIndex(Calls.TYPE))));                           
		Date date = new Date(Long.parseLong(cursor.getString(cursor.getColumnIndexOrThrow(Calls.DATE))));
		String time = sfd.format(date);                                                                  
		String name = cursor.getString(cursor.getColumnIndexOrThrow(Calls.CACHED_NAME));                 
		String duration = cursor.getString(cursor.getColumnIndexOrThrow(Calls.DURATION));
		callrecords.add(new CallEntity(type, time, "0", prenumber, duration));
		
		while(cursor.moveToPrevious()){
			String numbers = cursor.getString(cursor.getColumnIndex(Calls.NUMBER));
			int temptype = TypeDecision(Integer.parseInt(cursor.getString(cursor.getColumnIndex(Calls.TYPE))));                             
			Date tempdate = new Date(Long.parseLong(cursor.getString(cursor.getColumnIndexOrThrow(Calls.DATE))));
			String temptime = sfd.format(tempdate);                                                                  
			String tempname = cursor.getString(cursor.getColumnIndexOrThrow(Calls.CACHED_NAME));                 
			String tempduration = cursor.getString(cursor.getColumnIndexOrThrow(Calls.DURATION));
			
			if(!prenumber.equals(numbers) || !temptime.equals(time) || (temptype != type)){
				callrecords.add(new CallEntity(temptype, temptime, "0", numbers, tempduration));
				prenumber=numbers;
				time=temptime;
				type=temptype;
			}else{
				time=temptime;
				prenumber=numbers;
				type=temptype;
			}
		}
	}
}
           

随后需要建立一个适配器来显示相应的listview item，相信大家都会，网上也有很多资料可供大家参考，希望此篇文章对大家有所帮助，不对之处欢迎大家指正。
