Android 图文混排spannableStringBuilder简单使用

tvSpan = (TextView) findViewById(R.id.span);
String name = "小明";
String receiverName = "小红";
String expristion = "  b/12";
String receiver = "-回复：";
int len;//记录长度
//初始化对象
SpannableStringBuilder sb = new SpannableStringBuilder();
//发送人
sb.append(name);
sb.setSpan(new BackgroundColorSpan(Color.GREEN),//背景
0, name.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);//自动删除
sb.setSpan(new ForegroundColorSpan(Color.BLUE),//字体颜色
0, name.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
//回复
sb.append(receiver);
sb.setSpan(new ForegroundColorSpan(Color.RED), name.length(), sb.length(), Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
len = sb.length();
//接收人
sb.append(receiverName);
sb.setSpan(new StyleSpan(Typeface.BOLD), len, sb.length(), Spannable.SPAN_POINT_POINT);//加粗
sb.setSpan(new ForegroundColorSpan(Color.DKGRAY), len, sb.length(), Spannable.SPAN_POINT_POINT);//颜色
sb.setSpan(new UnderlineSpan(), len, sb.length(), Spannable.SPAN_POINT_POINT);//下划线
len = sb.length();
//获取图片
Drawable d = getResources().getDrawable(R.drawable.ic_launcher) ;
d.setBounds(0, 0,d.getIntrinsicWidth(), d.getIntrinsicHeight());//设置图片大小
sb.append(expristion);
sb.setSpan(new ImageSpan(d), len, sb.length(), Spannable.SPAN_COMPOSING);
tvSpan.setText(sb);

SpannableString ss = new SpannableString("红色打电话斜体删除线绿色下划线图片:.");
//用颜色标记文本
ss.setSpan(new ForegroundColorSpan(Color.RED), 0, 2,
//setSpan时需要指定的 flag,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE(前后都不包括).
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//用超链接标记文本
ss.setSpan(new URLSpan("tel:4155551212"), 2, 5,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//用样式标记文本（斜体）
ss.setSpan(new StyleSpan(Typeface.BOLD_ITALIC), 5, 7,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//用删除线标记文本
ss.setSpan(new StrikethroughSpan(), 7, 10,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//用下划线标记文本
ss.setSpan(new UnderlineSpan(), 10, 16,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//用颜色标记
ss.setSpan(new ForegroundColorSpan(Color.GREEN), 10, 13,
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//获取Drawable资源
Drawable d = getResources().getDrawable(R.drawable.icon);
d.setBounds(0, 0, d.getIntrinsicWidth(), d.getIntrinsicHeight());
//创建ImageSpan
ImageSpan span = new ImageSpan(d, ImageSpan.ALIGN_BASELINE);
//用ImageSpan替换文本
ss.setSpan(span, 18, 19, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
txtInfo.setText(ss);
txtInfo.setMovementMethod(LinkMovementMethod.getInstance()); //实现文本的滚动
