这是抛出我的函数 ArrayIndexOutOfBoundsException：rowIndex＆gt;可用行。在第if (!name.equalsIgnoreCase(realmResults.get(0).getName()) || !phoneNo.equalsIgnoreCase(realmResults.get(0).getPhone()) )行

代码在HTC 620g上正常运行，但在Moto G2和其他设备上崩溃。

RealmResults自动更新，因此当您编辑数据时，查询将被刷新。在你的情况下，它看起来像你在做：

RealmResults<R_LocalContactDB> realmResults = realmFresh.where(R_LocalContactDB.class).equalTo("phone", formattedPhoneNumber).findAll();


if (!name.equalsIgnoreCase(realmResults.get(0).getName()) || !phoneNo.equalsIgnoreCase(realmResults.get(0).getPhone()) ) {
  realmResults.get(0).setName(name);
  realmResults.get(0).setPhone(phoneNo); // This will make get(0) no longer part of the resultSet
}

realmResults.get(0).setMatchedWithRecent(true);

不要在任何地方使用.get(0)而只是缓存它：

R_LocalContactDB item = realmResults.get(0);
//...
item.setMatchedWithRecent(true);
