android - java.lang.IllegalArgumentException 由于 Spannable TextView

Question

我在我的 Google Play 控制台中收到了这份崩溃报告，我自己从未遇到过，也无法重现。

java.lang.IllegalArgumentException:

崩溃报告没有提到哪个类导致了崩溃。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);
    }

我自定义的 TextView 有问题吗？

Answer 1

我已经删除了你的 Html.fromHtml(definition[0]) 和 \n\n。然后效果很好。请测试这两个东西是否会出现。

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);
}

交叉检查您的文本是否正常。这一个 Html.fromHtml(definition[0])。不确定你为什么使用 \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。
