在Android上的IndexOutOfBoundsException,在SpannableStringBuilder.checkRange上的Code之外

Question

问题

自从升级到Android 8.0以来,我收到许多崩溃报告,说明IndexOutOfBoundsException这些报告发生在我的代码之外.

崩溃报告

没有代码 安卓 应用程序负责崩溃,它似乎是Android本身的一个错误.

可能的原因

因为它发生在TextView我认为它与我使用的这些元素有关:

         <TextView
              android:id="@+id/txtAlso"
              android:layout_width="0dp"
              android:layout_weight="1"
              android:layout_height="wrap_content"
              android:textColor="#0000AA"
              android:padding="5dp"
              android:textIsSelectable="true"
              android:text="" />

试过的解决方案

为了有希望修复这个错误,我已经重写了TextViews下面的代码,删除isSelectable标记并阻止视图聚焦.由于我无法自己重现这个错误,所以希望尽快获得更多信息.如果有人有信息,见解或知道解决方案回复或评论.

         <TextView
              android:id="@+id/txtAlso"
              android:layout_width="0dp"
              android:layout_weight="1"
              android:layout_height="wrap_content"
              android:textColor="#0000AA"
              android:padding="5dp"
              android:focusable="false" android:focusableInTouchMode="false"
              android:text="" />

Answer 1

我的应用程序发生了同样的崩溃。经过大量的研究和测试，我设法重新创建它。崩溃仅发生在 Oreo Android 8.0 设备上，而且几乎只发生在三星设备上。

在我的情况下，当单击 Linkify 创建的链接时触发了 IndexOutOfBounds 异常。

Linkify.addLinks(text, path, null, matchFilter, transforFilter);

我删除了 Linkify，并找到了另一种无需 Linkify 即可完成所需操作的方法。
