Crashlytics报告TextView.makeSingleLayout的倍数问题

Question

我收到有关同一错误的多次崩溃报告,但我不知道可能导致它的原因.

是抛出的异常是ArrayIndexOutOfBoundsException在android.widget.TextView.makeSingleLayout.

我知道它不是关于Android版本和设备类型,因为它从多个版本和设备获取报告.

以下是我从Crashlytics获得的内容:

那有什么解决方案吗？

我没有为TextView.makeSingleLayout编写显式实现.

Answer 1

已经差不多一年了,所以我对此的记忆有点模糊,但......

我遇到了我怀疑在自己的应用程序中遇到的问题.对我来说,它发生了,因为我在android:ellipsize="start" 没有使用的情况下使用android:singleLine="true".

我们已将所有android:singleLine="true"属性都切换为推荐值android:maxLines="1",但事实证明系统如何计算如果singleLine不存在则触发的省略号存在错误.

所以我相信你可以通过简单地添加android:singleLine="true"到TextView使用ellipsizeattrs的s 来解决这个问题.
