如何在 Android SDK 2.2 上检索未接来电 [英] How to retrieve missed calls on Android SDK 2.2

问题描述

在我的应用程序中，当来电但用户未接听时，我应该执行一些操作.

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

我在 android.telephony 和 NotificationManager 中搜索过，但没有找到解决此问题的方法.

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

有人知道如何知道电话上是否有未接来电吗?

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

这里是可以在通话记录中查询未接来电的代码.基本上，您必须以某种方式触发它，并确保您给通话记录一些时间(几秒钟应该这样做)来写入信息，否则如果您过早检查通话记录，您将找不到最近的通话.

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();
}

我希望你觉得这很有用.
