1. This is the stack information. Let's analyze it

2. The reason for the accident code is that it needs to insert an icon into a string

3. The length of the string is inconsistent

English string, 67 characters in length

You are not friends. Sending the video will cost you image %1$s COS

Chinese string, length 28, that is, 28 characters. I don't know why python says 62 characters. Sorry

You are not friends yet. Sending this video will cost you% 1$s COS

if(Float.parseFloat(mUserChatBean.getData().getCoc()) > 0) {
            String alt = String.format(getContext().getString(R.string.share_video_dialog_content), mUserChatBean.getData().getCoc());
            SpannableStringBuilder altBuilder = new SpannableStringBuilder(alt);
            Drawable d = getContext().getResources().getDrawable(R.drawable.no_padding_cos_icon);
            d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
            ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BOTTOM);
            altBuilder.setSpan(span, 53, 58, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
            mCocText.setText(altBuilder);
        } else {
            mCocText.setText(getContext().getString(R.string.share_video_dialog_content_free));
        }

4. The length of the string is inconsistent. The main culprit is here. To start from the 53rd character to the 58th character, you need to insert an icon Drawable, but the total length of the Chinese string is only 28 characters. Can you not crash? brother

altBuilder.setSpan(span, 53, 58, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

5. Look at Spannable's constant explanation

seeing the name of a thing one thinks of its function:

Spannable.SPAN_EXCLUSIVE_EXCLUSIVE //Not before or after

Spannable.SPAN_INCLUSIVE_EXCLUSIVE  //Include before not include after

Spannable.SPAN_EXCLUSIVE_INCLUSIVE  //Before excluding after

Spannable.SPAN_INCLUSIVE_INCLUSIVE  //Both before and after
