当我在寻找一个关键字＆＃34; i＆＃34;来自印度尼西亚，inggris和意大利。当我选择印度尼西亚，进入印度尼西亚活动，但当我选择inggris为什么进入马来西亚活动。如何进入所选活动？点击监听器有什么问题？帮帮我

Answer 1

＆＃39;位置＆＃39;来自lv对象，因此是过滤后的列表，而不是原始字符串列表。因此，当您选择＆＃34; inggris＆＃34;时，重新定位的位置为1并启动马来西亚活动。请尝试：

SELECT "purposes".id FROM "purposes" INNER JOIN "tale_purpose_joins" ON "purposes"."id" = "tale_purpose_joins"."purpose_id" WHERE "tale_purpose_joins"."tale_id" = ?  [["tale_id", 1]]

并更改其他＆＃34;位置＆＃34;到＆＃34; pos＆＃34;。
