類型TimePicker中的setCurrentMinute（Integer）方法不適用於參數（字符串）

Question

任何人都有一個想法，爲什麼我可能會得到這個錯誤？

我所要做的就是保存timepicker選擇的小時......我確定這是我忽略的一些簡單的東西。

任何幫助非常感謝！

Answer 1

的問題是，setCurrentHour()期望一個整數，但通過調用getString()你傳遞一個字符串，併爲錯誤狀態，對於setCurrentHour(String)沒有方法。

你不會告訴我們Intent的額外設置在哪裏，所以這個解決方案是一個猜測。但嘗試：

timeEt.setCurrentHour(extras.getInt("time")); 

Answer 2

如果額外對象沒有一個getInt()方法，你可以試試：timeEt.setCurrentHour(Integer.valueof(extras.getString("time")));
