我有一個「countDownTimer」的問題，當我在列表視圖中的兩個不同的行中運行兩個計數器時，「onfinish」功能只進行最後單擊行..listView與countDownTimer的onFinish方法問題
所以，「onfinish」方法會使對話框顯示上次點擊的文本視圖的文本。
但是，我希望「onfinish」方法顯示完成計數的特定點擊行的對話框。
這是代碼

希望每個單擊某一行的時間？你你需要它只有一次的第一單擊項目被彈出被彈出的對話框？ – Techfist
不，有一個計數器countDown，當我點擊原始...計數器達到值（0：0：0）後，對話框出現包含一個textview中存在的文本行.. 我需要當它們的計數器達到（0） –
好，請檢查我的答案 – Techfist
