無法制作EditText多行

我正在製作一個用於存儲筆記的Android應用程序。在點擊按鈕之前，我使editText的行爲與textView類似。點擊編輯按鈕可以使editText獲得價值。現在問題出現時，我保存該值，當它顯示。 EditText不會像我想的那樣進入多行，而是排成一行。無法制作EditText多行

我將editText的inputType屬性聲明爲xml文件中的多行，但是在初始化editText時的代碼中，我將它的inputType屬性設置爲null，以嘗試使其成爲null和多行但可嘆！它不會發生。

下面是我的XML和Java代碼：

This image is when I click edit button. This works just fine, text goes to another line.

This image is when i click the save button. The text goes back to single line instead of multi-line.

我向你保證，它不是：/ 我試過這個解決方案，它不適用於我的案例 –

如果你遇到了editTextContent問題：你可以在onCreate中將inputType設置爲「InputType.TYPE_NULL」（），稍後將其設置爲「InputType.TYPE_CLASS_TEXT |」 InputType.TYPE_TEXT_FLAG_MULTI_LINE'。如果您不是以「InputType.TYPE_NULL」開頭，而是使用其他輸入類型，那麼文本如何顯示？ – 0X0nosugar

如果我刪除了'InputType.TYPE_NULL'，雖然文本變成多行，但功能會中斷。刪除此行後，ediTextContent已準備好接受值。我的目標是隻有當我點擊編輯按鈕後才能使editTextContent取值。 –

好了，所以，我知道，當我點擊編輯按鈕，問題就出現了。即使我已經非常清楚地提到了XML中的多行輸入類型，單擊該按鈕會使editText單行內容自動排列。

我在點擊按鈕之後做了editText多行的操作是我在onClick按鈕代碼中的java文件中寫了editTextContent.setSingleLine(false);。就是這樣。 :)

是的，網站說我必須等48小時才能接受我的回答，我可以在6個小時內「檢查」商標。謝謝:) –
