由于 Spannable TextView 导致的 java.lang.IllegalArgumentException

Question

我在我的 Google Play Console 中收到了这个崩溃报告，我自己从未经历过，也无法重现。

java.lang.IllegalArgumentException:

崩溃报告没有提到导致崩溃的类。我最好的猜测是遵循自定义TextView。

private void customTextView(TextView view) {
        SpannableStringBuilder spanTxt = new SpannableStringBuilder(
                Html.fromHtml(definition[0]));
        spanTxt.append("\n\nExample");
        spanTxt.setSpan(new ClickableSpan() {
            @Override
            public void onClick(View view) {
                showAlert();
            }
        }, spanTxt.length() -"Example".length(), spanTxt.length(), 0);
        view.setMovementMethod(LinkMovementMethod.getInstance());
        view.setText(spanTxt, TextView.BufferType.SPANNABLE);
    }

我的习惯有问题TextView吗？

Answer 1

我已删除您的Html.fromHtml(definition[0])和\n\n。然后效果很好。请测试这两件事是否会出现。

private void customTextView(TextView view) {
    SpannableStringBuilder spanTxt = new SpannableStringBuilder("Testing");
    spanTxt.append("Example");
    spanTxt.setSpan(new ClickableSpan() {
        @Override
        public void onClick(View view) {
          Log.e("tag","show click");
        }
    }, spanTxt.length() -"Example".length(), spanTxt.length(), 0);
    view.setMovementMethod(LinkMovementMethod.getInstance());
    view.setText(spanTxt, TextView.BufferType.SPANNABLE);
}

交叉检查你的文本是否没有出现。这一个Html.fromHtml(definition[0])。不知道为什么你使用\n\n它会转到下一行。

检查这两件事。其他人工作得很好。

谢谢。
