【中文标题】java.lang.IndexOutOfBoundsException: setSpan (-1 ... -1) 在 Android 8.0 的 0 之前开始【英文标题】：java.lang.IndexOutOfBoundsException: setSpan (-1 ... -1) starts before 0 at Android 8.0 【发布时间】：2019-01-10 07:34:02 【问题描述】：问题 自从升级到 android 8.0 后，我收到许多崩溃报告，指出在我的代码之外发生的 IndexOutOfBoundsException。但与 the other question
不同崩溃报告 这似乎是Android本身的一个错误。但我想它是在我使用TextView内容中的链接时出现的。

public void setText(CharSequence text)
enforceNotSealed();
mOriginalText = text;
// Replace any ClickableSpans in mText with placeholders
if (text instanceof Spanned)
ClickableSpan[] spans =
((Spanned) text).getSpans(0, text.length(), ClickableSpan.class);
if (spans.length > 0)
Spannable spannable = new SpannableStringBuilder(text);
for (int i = 0; i < spans.length; i++)
ClickableSpan span = spans[i];
if ((span instanceof AccessibilityClickableSpan)
|| (span instanceof AccessibilityURLSpan))
// We've already done enough
break;
int spanToReplaceStart = spannable.getSpanStart(span);
int spanToReplaceEnd = spannable.getSpanEnd(span);
int spanToReplaceFlags = spannable.getSpanFlags(span);
spannable.removeSpan(span);
ClickableSpan replacementSpan = (span instanceof URLSpan)
? new AccessibilityURLSpan((URLSpan) span)
: new AccessibilityClickableSpan(span.getId());
spannable.setSpan(replacementSpan, spanToReplaceStart, spanToReplaceEnd,
spanToReplaceFlags);
mText = spannable;
return;
mText = (text == null) ? null : text.subSequence(0, text.length());
【问题讨论】：
我找到了原因，当用户在Android 8.0上打开Talkback时，可能会出现这个崩溃 【参考方案1】：尽量用字符串代替字符序列，请确保文本值不为空
【讨论】：
【参考方案2】：正如@chenjian chen 所说，如果在设置->辅助功能中启用了对讲，则可能会发生这种情况。我通过为导致此错误的视图添加 android:importantForAccessibility="no" 来解决此问题。
就我而言，我制作的 customView 是崩溃的原因。所以在构造函数中添加这一行修复问题：
setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_NO);:
