java – 如何从android(CallLog.Calls.CONTENT_URI)表中获取联系

我是 Android的新手并且正在开发一个应用程序,我需要所有传出呼叫日志,号码,呼叫持续时间和联系人姓名.所以我的问题是我可以获取android系统的CallLog.Calls.CONTENT_URI表的传出调用的名称和编号,或者我需要从单独的表中读取它并映射它.以下是我的代码.提前致谢.

private String getCallDetails() {

        StringBuffer sb = new StringBuffer();
        // Cursor managedCursor =
        // getContentResolver().query(CallLog.Calls.CONTENT_URI,null,// null,null);

        Cursor managedCursor = getContentResolver().query(CallLog.Calls.CONTENT_URI,CallLog.Calls.DATE + ">?",new String[] { String.valueOf("1451586601000") },CallLog.Calls.NUMBER + " asc");
        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);
        int name = managedCursor.getColumnIndex(CallLog.Calls.CACHED_NAME);
        // int geoCodeColumn =
        // managedCursor.getColumnIndex(CallLog.Calls.GEOCODED_LOCATION);

        // sb.append("Call Details :");
        while (managedCursor.moveToNext()) {
            String phNumber = managedCursor.getString(number);
            String callType = managedCursor.getString(type);
            String callDate = managedCursor.getString(date);
            String callerName = managedCursor.getString(name);
            // long calldate_timeStamp= Long.parseLong(callDate);
            // long temp_time = 1451586601000L;
            // if(calldate_timeStamp>temp_time){
            // String geoCode = managedCursor.getString(geoCodeColumn);
            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";
                int total_call_duration = Integer.parseInt(callDuration);
                total_time = total_time + total_call_duration;
                MyContact dialedContact = new MyContact();
                dialedContact.setPhoneNumber(Long.parseLong(phNumber));
                dialedContact.setCallDuration(Integer.parseInt(callDuration));
                // dialedContact.se
                 sb.append("nPhone Number:--- " + phNumber + " nCallType:--- "
                 + dir + " nCall Date:--- " + callDayTime
                 + " nCall duration in sec :--- " + callDuration+ " nGeocode: " );
                 sb.append("n----------------------------------");

                break;

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

            case CallLog.Calls.MISSED_TYPE:
                dir = "MISSED";
                break;
            }
        }

        // }
        managedCursor.close();
    //  sb.append("" + total_time / 60);// call duration in minute
        return sb.toString();

    }

startActivityForResult(intent,PICK_CONTACT);

@Override
public void onActivityResult(int reqCode,int resultCode,Intent data) {
  super.onActivityResult(reqCode,resultCode,data); 
switch (reqCode) {
case (PICK_CONTACT) :
if (resultCode == Activity.RESULT_OK) {
Uri contactData = data.getData();
Cursor c =  getContentResolver().query(contactData,null);
if (c.moveToFirst()) {
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
// TODO Whatever you want to do with the selected contact name. 
    }
}
break;
    }
