2我需要一些有关此代码的帮助。我收到一个 IndexOutOfBoundsException。我知道为什么,但我一直在努力解决它。问题:eMain.getElementsByClass("trA1").size() = 8 和 eMain.getElementsByClass("trA2").size() = 7(尺寸很多,但 trA1 总是大于 trA2)。我需要将每个元素添加到 ArrayList 作为 add(trA1), add(trA2), add(trA1), add(trA2)...... (我正在使用 for 循环)但是当我得到到元素 8,我得到了异常,因为没有 trA2 元素 8。我尝试了一个 If 语句来检查元素是 null 还是“”,但我仍然得到了异常。有任何想法吗。
// game list data
if (!eMain.equals("")) {
for (int i=0; i < eMain.getElementsByClass("trA1").size(); i++) {
// check if AsyncTask was cancelled
if (isCancelled())
break;
if (eMain.getElementsByClass("trA1").select("strong").get(i).text() != null) {
// get string data
String titleA1 = eMain.getElementsByClass("trA1").select("strong").get(i).text();
String achAmountA1 = eMain.getElementsByClass("trA1").select("td[align]").get(mAchAmountCounter).text();
String gsAmountA1 = eMain.getElementsByClass("trA1").select("td[align]").get(mGsAmountCounter).text();
String aPageLinkA1 = eMain.getElementsByClass("trA1").select("td a").get(mPageLinkCounter).attr("abs:href");
String iconSrcA1 = eMain.getElementsByClass("trA1").select("td a img").get(i).attr("abs:src");
// create game object
GameObject gameObjectA1 = new GameObject();
gameObjectA1.setGlTitle(titleA1);
gameObjectA1.setGlAchAmount(achAmountA1 + " achievements");
gameObjectA1.setGlGSAmount(gsAmountA1 + " gamer score");
gameObjectA1.setGlAchPageUrl(aPageLinkA1);
gameObjectA1.setGlIcon(iconSrcA1);
mGameObjectList.add(gameObjectA1);

// counters
mPageLinkCounter += 3;

mGsAmountCounter += 2;
// update progress bar
publishProgress((100 / (Integer) Math.round(eA1.size())));
}
