android - Crashlytics 报告 TextView.makeSingleLayout 的多个问题

Question

我收到了多个关于同一错误的崩溃报告，但我不知道是什么原因导致的。

抛出的异常是 android.widget.TextView.makeSingleLayout 中的 ArrayIndexOutOfBoundsException。

我知道这与 Android 版本和设备类型无关，因为它从多个版本和设备获取报告。

这是我从 Crashlytics 获得的信息:

有什么解决办法吗？

我没有为 TextView.makeSingleLayout 编写明确的实现。

Answer 1

已经快一年了，所以我对这件事的内存有点模糊，但是......

我怀疑在我自己的应用程序中遇到了同样的问题。对我来说，这是因为我使用了 android:ellipsize="start" 而没有 也使用了 android:singleLine="true"。

我们已将所有 android:singleLine="true" 属性切换为推荐的 android:maxLines="1"，但事实证明存在错误如果 singleLine 不存在，系统如何计算触发的省略号。

所以我相信您可以通过简单地将 android:singleLine="true" 添加到使用 ellipsize 的 TextView 来解决这个问题属性。
