如何找回在Android SDK 2.2未接来电 [英] How to retrieve missed calls on Android SDK 2.2

问题描述

在我的应用程序，我应该做一些动作，当有电话打进来，而不是由用户回答。

in my app I should do some action when a call comes but not answered by the user.

我有搜索在 android.telephony 的和的 NotificationManager 的，但我还没有找到一个方法来解决这个问题。

I have searched in the android.telephony and the NotificationManager, but I haven't found a method to solve this problem.

是否有人有一个如何得到一个想法，以了解是否有手机上的一个未接来电或不？

Does someone have an idea of how to get to know if there is a missed call on the phone or not ?

推荐答案

下面是code，可以查询通话记录的未接来电。基本上，你将不得不以某种方式引发这一点，并确保你给通话记录一段时间（几秒钟应该这样做）以其他方式写入信息，如果你太早查看通话记录，你不会找到最近调用。

Here is code that can query the call log for a missed call. Basically, you will have to trigger this somehow and make sure that you give the call log some time ( a few seconds should do it) to write the information otherwise if you check the call log too soon you will not find the most recent call.

final String[] projection = null;
final String selection = null;
final String[] selectionArgs = null;
final String sortOrder = android.provider.CallLog.Calls.DATE + " DESC";
Cursor cursor = null;
try{
    cursor = context.getContentResolver().query(
            Uri.parse("content://call_log/calls"),
            projection,
            selection,
            selectionArgs,
            sortOrder);
    while (cursor.moveToNext()) { 
        String callLogID = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls._ID));
        String callNumber = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.NUMBER));
        String callDate = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.DATE));
        String callType = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.TYPE));
        String isCallNew = cursor.getString(cursor.getColumnIndex(android.provider.CallLog.Calls.NEW));
        if(Integer.parseInt(callType) == MISSED_CALL_TYPE && Integer.parseInt(isCallNew) > 0){
            if (_debug) Log.v("Missed Call Found: " + callNumber);
        }
    }
}catch(Exception ex){
    if (_debug) Log.e("ERROR: " + ex.toString());
}finally{
    cursor.close();
}
