1，通过Html.fromHtml（..）来实现[mw_shl_code=java,true]eText.append(Html.fromHtml("<img src='" + R.drawable.ohoh + "'/>",imageGetter, null));[/mw_shl_code]
2，通过ImageSpan与SpannableString/SpannableStringBuilder.
[mw_shl_code=java,true]SpannableString ss = new SpannableString(imgStr);Drawable drawable = getResources().getDrawable(R.drawable.bad_smelly);drawable.setBounds(0, 0, drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight());ImageSpan imageSpan = new ImageSpan(drawable,ImageSpan.ALIGN_BASELINE);ss.setSpan(imageSpan, 0, imgStr.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);eText.append(ss);
