在 android 中觸摸 EditText 時應用程序崩潰

Question

當EditText視圖為空時，我可以觸摸它並開始輸入數據。 但是當我在輸入一些數據時觸摸它時，應用程序崩潰，並給出以下堆棧跟蹤：

我不確定我應該提供哪些代碼，因為我有幾個類和已經很復雜的邏輯，所以我認為我應該首先了解問題的真正含義。

這是EditText的 xml 代碼：

<EditText
    android:id="@+id/input"
    android:importantForAutofill="no"
    android:textSelectHandle="@null"
    android:visibility="visible"
    android:layout_width="180dp"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentTop="true"
    android:background="@drawable/rounded_field"
    android:inputType="number"
    android:textCursorDrawable="@null"
    android:padding="8dp"
    android:layout_marginTop="12dp"
    android:layout_marginBottom="16dp"
    android:textSize="22sp"
    tools:ignore="LabelFor" />

Answer 1

我知道了。 當我更改了這些行時：

android:textSelectHandle="@null"

和

android:textCursorDrawable="@null"

一切都恢復了正常。 我應該使用透明預設或其他東西而不是@nulls。

Answer 2

android:textSelectHandle="@null"的原因是，當您單擊可編輯文本中的某個點時，會出現一個指針。 將其設置為@null將阻止它出現，因為沒有與該參數對應的此類資源，這會導致程序崩潰。 將其設置為"@android:color/transparent" 。
