ImageSpan的使用

编辑框中加图片,以前一直以为很复杂,后来发现android有些类已经很好的实现了这些功能.

代码如下:

        mSubjectDetailView = (TextView) findViewById(R.id.subject_detail);
        
        CharSequence text = "如图所示★，dsfdsfdddd，如果fdsfs★东东";
        SpannableStringBuilder builder = new SpannableStringBuilder(text);
        String rexgString = "★";
        Pattern pattern = Pattern.compile(rexgString);
        Matcher matcher = pattern.matcher(text);

        while (matcher.find()) {
            builder.setSpan(
                    new ImageSpan(this, R.drawable.ic_launcher), matcher.start(), matcher
                            .end(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        }

        mSubjectDetailView.setText(builder);
