首先讀取通話記錄許可權：

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

和上一篇一樣，先判斷許可權是否獲取，然後再進行相關操作。
主要程式碼：

private void initRecord() {
        Uri uri = CallLog.Calls.CONTENT_URI;
        if (ActivityCompat.checkSelfPermission(getActivity(),
                Manifest.permission.READ
 
_CALL_LOG) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(getActivity(),
                    new String[]{Manifest.permission.READ_CALL_LOG}, READ_CONTACTS_PERMISSIONS_REQUEST);
            return;
        }

        Cursor cursor = getActivity().getContentResolver
 
().query(uri, null, null, null, null);
        if (cursor.moveToFirst()) {
            do {

                RecordEntity recordEntity = new RecordEntity();
                //號碼
                recordEntity.setNumber(cursor.getString(cursor.getColumnIndex(CallLog.Calls.NUMBER)));
                //呼叫型別
                recordEntity.setType
 
(Integer.parseInt(cursor.getString(cursor.getColumnIndex(CallLog.Calls.TYPE))));


                SimpleDateFormat sfd = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
                Date date = new Date(Long.parseLong(cursor.getString(cursor.getColumnIndexOrThrow(CallLog.Calls.DATE))));
                //呼叫時間
                recordEntity.setlDate(sfd.format(date));
                //聯絡人
                recordEntity.setName(cursor.getString(cursor.getColumnIndexOrThrow(CallLog.Calls.CACHED_NAME)));

                Log.e("---------->", cursor.getString(cursor.getColumnIndexOrThrow(CallLog.Calls.CACHED_NAME))+"");

                //通話時間,單位:s
                recordEntity.setDuration(cursor.getString(cursor.getColumnIndexOrThrow(CallLog.Calls.DURATION)));

                recordEntityList.add(recordEntity);
            } while (cursor.moveToNext());
        }

        getActivity().startManagingCursor(cursor);//cursor的生命週期託管給activity


        //設定列表資料和浮動header
        final LinearLayoutManager layoutManager = new
                LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false);
        recyclerView.setLayoutManager(layoutManager);

        RecordAdapter recordAdapter = new RecordAdapter();
        recyclerView.setAdapter(recordAdapter);

        // Add decoration for dividers between list items
        recyclerView.addItemDecoration(new DividerDecoration(getActivity()));


    }
