Android開發之通話記錄

本文主要實作類似iPhone通話記錄效果，即相鄰通話如果通話号碼相同、通話類型（呼入、呼出、未接）相同、間隔時間（某一門檻值範圍内），則将其歸為一條記錄，否則，将其分别顯示。首先擷取通話記錄必須添加一下權限：

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

然後通過一下代碼擷取通話記錄：

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

然後須通過周遊通話記錄，按照顯示規則進行顯示，在此需了解Cursor的相關知識：cursor.moveToFirst表示移動至目前記錄的第一條，cursor.moveToNext表示目前記錄的下一條記錄，cursor.moveToPrevious表示目前記錄的上一條記錄，cursor.moveToLast表示目前記錄的最後一條記錄，一般moveToFirst和moveToNext、moveToPrevious和moveToLast配套使用。随後我們進行通話記錄顯示：

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;
			}
		}
	}
}
           

随後需要建立一個擴充卡來顯示相應的listview item，相信大家都會，網上也有很多資料可供大家參考，希望此篇文章對大家有所幫助，不對之處歡迎大家指正。
