Question

我正在尝试使用此代码获取通话记录，但我收到的错误是managedQuery未定义服务：

        private void getCallDetails() {
        StringBuffer sb = new StringBuffer();
        Cursor managedCursor = managedQuery( CallLog.Calls.CONTENT_URI,null, null,null, null);
        int number = managedCursor.getColumnIndex( CallLog.Calls.NUMBER ); 
        int type = managedCursor.getColumnIndex( CallLog.Calls.TYPE );
        int date = managedCursor.getColumnIndex( CallLog.Calls.DATE);
        int duration = managedCursor.getColumnIndex( CallLog.Calls.DURATION);
        sb.append( "Call Details :");
        while ( managedCursor.moveToNext() ) {
        String phNumber = managedCursor.getString( number );
        String callType = managedCursor.getString( type );
        String callDate = managedCursor.getString( date );
        Date callDayTime = new Date(Long.valueOf(callDate));
        String callDuration = managedCursor.getString( duration );
        String dir = null;
        int dircode = Integer.parseInt( callType );
        switch( dircode ) {
        case CallLog.Calls.OUTGOING_TYPE:
        dir = "OUTGOING";
        break;

        case CallLog.Calls.INCOMING_TYPE:
        dir = "INCOMING";
        break;

        case CallLog.Calls.MISSED_TYPE:
        dir = "MISSED";
        break;
        }
        sb.append( "\nPhone Number:--- "+phNumber +" \nCall Type:--- "+dir+" \nCall Date:--- "+callDayTime+" \nCall duration in sec :--- "+callDuration );
        sb.append("\n----------------------------------");
        }
        managedCursor.close();
        }
}

有没有办法在服务类中进行，因为我想让它在服务类中工作？

我收到的错误是没有为Service定义managedQuery

managedQuery()是Activity上弃用的方法。

有没有办法在服务类中进行，因为我想让它在服务类中工作。

在query()上致电ContentResolver。您可以通过ContentResolver致电getContentResolver()来获得Service。并且，请在后台线程上调用query()，因为它将涉及磁盘I / O和IPC。

托管查询没有为服务定义？
