android - カウントダウンタイマーの問題

Question

私はカウントダウンタイマーを使用しており、ユーザーが設定できるように設定しています。タイマーが 00:00 になると、"done!" と表示されます。なぜか「できた！」タイマーをスタートさせた直後。一時停止して再開すると、カウンターのカウントダウンが表示されますが、顧客がこれで冷静になるかどうかはわかりません. なぜ私がこの問題を抱えているのか誰にもわかりますか? ありがとう。

Answer 1

初期化コードを切り落とすと、ブレースのバランスが取れていないことに気付くのに時間がかかりすぎて混乱しました...

カウンターを作成し、両方の onclick 関数の外で初期化しているようです。この段階で長さはゼロです。

開始ボタンをクリックすると、長さが有効な時間に設定されますが、タイマーは再初期化されないため、以前に設定されたゼロの値から開始され、onFinish がすぐに起動します。

一時停止を押すと、正しい残り時間が計算され、再開時に作成した新しいカウンターに渡され、通常のカウントダウンに進みます。

counter = new MyCount(length, 100);すぐ後ろに移動 dialog.show();}すると、タイマーの設定ボタンがクリックされたときにカウンターが初期化され、問題が修正されます。
