当我在TextView中多次尝试选择文本时,应用程序会崩溃并显示错误。
有人知道可能的问题是什么吗?

以下是TextView的标记代码:
原始回答
<TextView
android:id="@+id/list_item_message_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="6dp"
android:layout_marginBottom="6dp"
android:gravity="center_vertical"
android:inputType="none"
android:linksClickable="true"
android:singleLine="false"
android:text="TextView"
android:lineSpacingExtra="3dp"
android:textIsSelectable="true"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintTop_toTopOf="parent" />
在代码中我设置了属性:messageView.setMovementMethod(LinkMovementMethod.getInstance());,它的作用是使文本可以响应点击事件。
