android textview里链接点击事件，增加图片

Android系统默认给TextView插入图片提供了三种方式：

1、ImageSpan

2、Html.ImageGetter

3、TextView.setCompoundDrawables(left, top, right, bottom)

1、TextView使用ImageSpan显示图片

ImageSpan span = new ImageSpan(this, R.drawable.ic_launcher);

SpannableString spanStr = new SpannableString("http://orgcent.com");

spanStr.setSpan(span, spanStr.length()-1, spanStr.length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

mTVText.setText(spanStr);

PS:关于SpannableString相关的其他span，查看[Android教程]TextView使用SpannableString设置复合文本

2、使用Html.ImageGetter显示网页中的图片

查看文章：[Android教程]TextView显示Html类解析的网页和图片及自定义标签

3、在TextView四周显示图片

mTVText.setText("setCompoundDrawables");

Drawable d = getResources().getDrawable(R.drawable.ic_launcher);

d.setBounds(0, 0, 50, 50); //必须设置图片大小，否则不显示

mTVText.setCompoundDrawables(d , null, null, null);
