多应用中EditText中可以插入图片，并且图片可以响应点击事件来进行相关操作。

看到很多应用中EditText中可以插入图片，并且图片可以响应点击事件来进行相关操作。

比如很多MMS应用中可以在EditText中直接编辑彩信，于是通过搜索来看看别人到底是怎么实现的，自己也想试试。

EditText中插入图片基本就是两种方法：

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);[/mw_shl_code]

下面贴上完整代码，

点击事件通过增加ClickableSpan来实现。
