@Override

if (cursor != null && cursor.getCount() > 0) {

callLogs = new ArrayList();

SimpleDateFormat sfd = new SimpleDateFormat("MM-dd hh:mm");

Date date;

cursor.moveToFirst(); // 游標移動到第一項

for (int i = 0; i < cursor.getCount(); i++) {

cursor.moveToPosition(i);

date = new Date(cursor.getLong(cursor

.getColumnIndex(CallLog.Calls.DATE)));

String number = cursor.getString(cursor

.getColumnIndex(CallLog.Calls.NUMBER));

int type = cursor.getInt(cursor

.getColumnIndex(CallLog.Calls.TYPE));

String cachedName = cursor.getString(cursor

.getColumnIndex(CallLog.Calls.CACHED_NAME));// 緩存的名稱與電話號碼，如果它的存在

int id = cursor.getInt(cursor

.getColumnIndex(CallLog.Calls._ID));

CallLogBean callLogBean = new CallLogBean();

callLogBean.setName(cachedName);

if (null == cachedName || "".equals(cachedName)) {

callLogBean.setName(number);

}

callLogBean.setType(type);

callLogBean.setDate(sfd.format(date));

callLogs.add(callLogBean);

}

if (callLogs.size() > 0) {

}

}

super.onQueryComplete(token, cookie, cursor);

}

}

private void setAdapter(List callLogs) {

adapter = new DialAdapter(this, callLogs);

callLogListView.setAdapter(adapter);

}

}

代碼是最好的解釋了，這里使用的幾個重要的類，一個是Uri(進行查詢的通用資源標志符)，一個是AsyncQueryHandler(Android提供的異步操作數據庫的類)，這里我們調用它的startQuery方法來查詢數據庫，在它onQueryComplete方法中得到數據庫返回的游標cousor，通過curor來取得數據庫對應表中的字段值。
