TextView使用SpannableString设置复合文本


1、BackgroundColorSpan 背景色

SpannableString spanText = new SpannableString("萝卜白菜的博客 -- http://orgcent.com");spanText.setSpan(new BackgroundColorSpan(Color.GREEN), 0, spanText.length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

2.ForegroundColorSpan 文本颜色（前景色）

spanText = new SpannableString("萝卜白菜的博客 -- http://orgcent.com");spanText.setSpan(new ForegroundColorSpan(Color.BLUE), 6, spanText.length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

3.MaskFilterSpan 修饰效果，如模糊(BlurMaskFilter)、浮雕(EmbossMaskFilter)

spanText = new SpannableString("MaskFilterSpan -- http://orgcent.com");int length = spanText.length();//模糊(BlurMaskFilter)MaskFilterSpan maskFilterSpan = new MaskFilterSpan(new BlurMaskFilter(3, Blur.OUTER));spanText.setSpan(maskFilterSpan, 0, length - 10, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);//浮雕(EmbossMaskFilter)maskFilterSpan = new MaskFilterSpan(new EmbossMaskFilter(new float[]{1,1,3}, 1.5f, 8, 3));spanText.setSpan(maskFilterSpan, length - 10, length, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

4.RasterizerSpan 光栅效果

spanText = new SpannableString("StrikethroughSpan");spanText.setSpan(new StrikethroughSpan(), 0, 7, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

5.StrikethroughSpan 删除线（中划线）

spanText = new SpannableString("StrikethroughSpan");spanText.setSpan(new StrikethroughSpan(), 0, 7, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

6.UnderlineSpan 下划线

spanText = new SpannableString("UnderlineSpan");spanText.setSpan(new UnderlineSpan(), 0, spanText.length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

7.DynamicDrawableSpan 设置图片，基于文本基线或底部对齐。

DynamicDrawableSpan drawableSpan = new DynamicDrawableSpan(DynamicDrawableSpan.ALIGN_BASELINE) {    @Override    public Drawable getDrawable() {        Drawable d = getResources().getDrawable(R.drawable.ic_launcher);        d.setBounds(0, 0, 50, 50);        return d;    }};DynamicDrawableSpan drawableSpan2 = new DynamicDrawableSpan(DynamicDrawableSpan.ALIGN_BOTTOM) {    @Override    public Drawable getDrawable() {          Drawable d = getResources().getDrawable(R.drawable.ic_launcher);          d.setBounds(0, 0, 50, 50);                return d;            }        };spanText.setSpan(drawableSpan, 3, 4, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);spanText.setSpan(drawableSpan2, 7, 8, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

8.左边图片基于基线对齐，右边图片基于底部对齐

spanText = new SpannableString("ImageSpan");Drawable d = getResources().getDrawable(R.drawable.ic_launcher);</strong>d.setBounds(0, 0, 50, 50);spanText.setSpan(new ImageSpan(d), 3, 4, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

9.ScaleXSpan 基于x轴缩放

spanText = new SpannableString("ScaleXSpan -- 萝卜白菜的博客");//参数proportion:比例大小spanText.setSpan(new ScaleXSpan(3.8f), 3, 7, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

10.SubscriptSpan 下标（数学公式会用到）

spanText = new SpannableString("SubscriptSpan -- 萝卜白菜的博客");spanText.setSpan(new SubscriptSpan(), 6, 7, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

11.SuperscriptSpan 上标（数学公式会用到）

spanText = new SpannableString("SuperscriptSpan -- 萝卜白菜的博客");spanText.setSpan(new SuperscriptSpan(), 6, 7, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);

12.URLSpan 文本超链接

spanText = new SpannableString("URLSpan -- 萝卜白菜的博客");spanText.setSpan(new URLSpan("http://orgcent.com"), 10, spanText.length(), Spannable.SPAN_INCLUSIVE_EXCLUSIVE);mTVText.append("\n");mTVText.append(spanText);//让URLSpan可以点击mTVText.setMovementMethod(new LinkMovementMethod());
