我希望你能幫助我與這些 我想從我的解析數據庫中提取信息爲我的android應用程序（只是一個查看應用程序） 基本上我想要做的是我去選擇第一個條件：當前解析用戶=當前用戶（來自數據庫） 第二個條件：旋轉器上的選定項目（旋轉月）=月（第二個條件）來自數據庫） 第三種情況：微調器上的選定項二（旋轉年）=年（來自數據庫）安卓解析查詢與mutltiple條件
然後它會給我需要每個文本視圖中的數據（我可以只用一個條件要做到這一點，但我需要指定它分爲3個條件）
類名稱：從類工資單 列名：用戶名，一年，一年
我不確定是哪一種或哪一種if語句，開關盒或任何我可以使用的，所以我可以適應這三個條件 感謝一幫人的幫助！
