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(newBackgroundColorSpan(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(newForegroundColorSpan(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(newBlurMaskFilter(3, Blur.OUTER));

spanText.setSpan(maskFilterSpan,0, length - 10, Spannable.

SPAN_INCLUSIVE_EXCLUSIVE);

//浮雕(EmbossMaskFilter)

maskFilterSpan = new MaskFilterSpan(newEmbossMaskFilter(newfloat[]{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(newScaleXSpan(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 =

 newDynamicDrawableSpan(DynamicDrawableSpan.ALIGN_BASELINE) {

 @Override

 publicDrawable getDrawable() {

  Drawable d = getResources().getDrawable(R.drawable.ic_launcher);

  d.setBounds(0,0, 50,50);

  returnd;

 }

};

DynamicDrawableSpan drawableSpan2 =new DynamicDrawableSpan(

DynamicDrawableSpan.ALIGN_BOTTOM) {

 @Override

 publicDrawable getDrawable() {

   Drawable d = getResources().getDrawable(R.drawable.ic_launcher);

   d.setBounds(0,0, 50,50);

    returnd;

   }

  };

spanText.setSpan(drawableSpan,3, 4, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

spanText.setSpan(drawableSpan2,7, 8, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);

mTVText.append("\n");

mTVText.append(spanText);
