【问题描述】：
当EditText 视图为空时，我可以触摸它并开始输入数据。但是当我在输入一些数据时触摸它时，应用程序崩溃，并给出以下堆栈跟踪：

我不确定我应该提供哪些代码，因为我有几个类和已经很复杂的逻辑，所以我认为我应该首先了解问题的真正原因。
这是EditText的xml代码：
<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" />
