Android(安卓)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);

效果

背景色是跟着图片拉长的。只要控制好图片大小就可以了。

总结一下：spannableStringBuilder使用，最后一定要放在一个textview中显示。

网上搜集的方法：

 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
