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());

调用隐藏api
1，可以使用反射
2，使用全编译的class.jar，
android 编译后，framework层生成的class.jar
目录在
out\target\common\obj\JAVA_LIBRARIES\framework_intermediates
找到后在eclipse中拷到项目根目录，加入包引用。

下面是2.3的class.jar

VI使用使用方法
Command->Edit(i,a,o)

Edit-->Command(Esc)

Command-->Ex(:)

Ex--->Command(Enter)


Edit-->Ex(can not)


Ex--->Edit(can not)
