问题 自从升级到Android 8.0以来，我收到了很多崩溃报告，指出我的代码之外发生了IndexOutOfBoundsException。但是与the other question
不同崩溃报告 这似乎是Android本身的错误。但是我猜想，当我在TextView的内容中使用链接时，它就会出现。

在源代码中，AccessibilityNodeInfo.java和setText（）方法可能出了点问题。但是我不知道。我需要帮助。谢谢
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());
}

尝试使用字符串代替字符序列，并确保文本值不为空

如@chenjian chen所述，如果在“设置”->“可访问性”中启用了“对讲”，则可能会发生。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。因此，在构造函数已修复的问题中添加以下行：
setImportantForAccessibility(View.IMPORTANT_FOR_ACCESSIBILITY_NO);：
