如何解决Blackberry PIM为什么联系人创建如此缓慢？
| 以下代码是我从blackberry论坛上获取的，花费了将近26分钟的时间，才能在8500系列设备上使用BB PIM API创建2000个随机联系人。有谁知道为什么要花这么长时间或如何提高通讯录中联系人创建的性能？public static void testContactCreation() {
ContactList contacts = null;
try {
contacts = (ContactList) PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_WRITE);
} catch (PIMException e) {
// An error occurred
return;

解决方法
Hm .. 2000分钟接触26分钟意味着每1个接触780毫秒。
1）。您能检查一下ѭ1不是最耗时的电话吗？您可以使用smth这样比较准确地做到这一点：
long timeSpentOnCommits; // defined somewhere at a top level
...
long start = System.currentTimeMillis();
contact.commit();
long taken = System.currentTimeMillis() - start;
timeSpentOnCommits += taken;
...
// then after the all contacts have been added you can get
// an average commit time:
long timePerOneCommit = timeSpentOnCommits / 2000;
// view the got value in a `Dialog` or some logging
StringBuffer
addr[Contact.ADDR_POSTALCODE] =
arrSzAlphas[generator.nextInt(arrSzAlphas.length)]
+ arrSzAlphas[generator.nextInt(arrSzAlphas.length)]

+ Integer.toString(generator.nextInt(9))
+ \" \"
