Android TextView使用SpannableString设置复合文本的方法

1、BackgroundColorSpan 背景色 SpannableString spanText = new SpannableString( "脚本之家 -- http://www.jb51.net" ); 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( "脚本之家 -- http://www.jb51.net" ); 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://www.jb51.net" ); 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、ScaleXSpan 基于x轴缩放 spanText = new SpannableString( "ScaleXSpan -- 脚本之家" ); //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); 5、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);
