textview实现多个文字着色和增加多个图片

代码如下：

public class StringColor {

            int start=text.indexOf(str);
            int end=start+str.length();
            builder.setSpan(new ForegroundColorSpan(color),start,
                    end, SpannableString.SPAN_EXCLUSIVE_EXCLUSIVE);

        return builder;
    }
    
    public static SpannableStringBuilder setLeftImageText(String text, Drawable... drawables){
        SpannableStringBuilder builder=new SpannableStringBuilder();
        String iconTag = "[icon]";
        if (drawables!=null&&drawables.length>0){
            for (int i = 0; i
