複利計劃將不計算

我一直在試圖讓這個計劃的工作，但由於某種原因，它不會計算複合利息。一點幫助，將不勝感激。注意我沒有完成if語句，無論輸入到compoundInterestEditText字段中的任何值如何。我希望它能與我所擁有的一起工作。 endValueEditText甚至不會更新。複利計劃將不計算

你發佈了很多內容，但忘了清楚地解釋「不工作」。 – kosa

什麼不起作用？你有錯誤嗎？ –

我確實說過什麼不起作用。我說endValueEditText（這是最終複合計算沒有顯示任何值）。 – Dee129

我猜你收到一個堆棧溢出異常，因爲setText()電話onTextChanged()其中調用updateValues()哪些調用setText()這呼籲...（一遍又一遍）。只需一個布爾值添加到您的TextWatcher：

private TextWatcher endValueEditTextWatcher = new TextWatcher() { 
    boolean update = false; 
    public void onTextChanged(CharSequence s, int start, int before, int count) { 
     update = !update; 
     if(!update) 
      return; 

     ... 
    } 
}

但我認爲你已經創建了一個奇怪的用戶界面：只有當用戶鍵入一個值endValueEditText將updateValues()運行。我認爲你應該創建一個標記爲「計算興趣」的按鈕，然後閱讀此Button的OnClickListener中的EditText值。你也應該把endValueEditText改成TextView，因爲用戶調用確實改變了這個值。

是的，我同意，我一直在一本書中遵循一個類似的例子，我一直試圖實現我自己的版本（上圖）。我同意一個計算按鈕要容易得多，但我已經做到了。感謝您的輸入。我非常感激。 – Dee129

如果您認爲任何答案（或問題）有用，您應該點擊向上箭頭讓每個人都知道。如果這個答案解決了你的問題，請點擊對號。如果它不讓我知道我是否可以回答更具體的問題。 – Sam

我試過你的建議，但沒有奏效。 endValueEditText字段仍然沒有顯示任何值，因爲我將值輸入到其他字段中。 – Dee129
