长按EditText

Question

我有以下EditText：

<EditText
  android:id="@+id/et_username"
  android:layout_width="0dp"
  android:layout_height="match_parent"
  android:layout_weight="0.8"
  android:background="#E6E6E6"
  android:gravity="center_vertical"
  android:hint="USERNAME"
  android:paddingRight="5dp"
  android:singleLine="true"
  android:textAppearance="@null"
  android:textColor="#9C9C9C"
  android:textColorHint="#ADADAD"
  android:textSize="20sp"/>

当我将文本粘贴到其中时，我收到以下错误：

当EditText为空时，它会发生。

此外，textColor属性没有做任何事情，它只适用于textAppearance @null。这种情况发生在所有EditText和TextView中，但不适用于Button。

这与Android Studio或我的项目有关吗？

您的问题是您正在尝试复制比editText的maxValue字符串更长的内容

   Caused by: java.lang.ArrayIndexOutOfBoundsException: length=15; index=389

您可以使用android:maxLength="400"或控制您要在那里设置的字符串长度来解决它
