TextView多样式字体实现

先看下图

TextView是可以修改字体大小，颜色等。要想实现自定义的文字，我们需要用到SpannableString。

 public class MainActivity extends Activity {TextView mTextView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mTextView = (TextView) findViewById(R.id.text);//创建SpannableString对象,内容不可修改SpannableString ss=new SpannableString("字体测试字体绝对大小相对大小缩放大小" +"前景颜色背景颜色字体样式下划线删除线上标X2下标Y3链接" +"字体外表图图图图");//使用setSpan()方法设置标记对象//使用removeSpan()解绑标记对象//public void setSpan (Object what, int start, int end, int flags)//绑定特定的标记对象（Object what）到起始为start，终止为end的text对象上(若已绑定标记对象则先移除)//设置字体TypefaceSpan()//设置字体大小(绝对值)AbsoluteSizeSpan()//设置字体大小(相对值)RelativeSizeSpan()//设置字体大小(相对值,默认字体宽度的倍数)ScaleXSpan()//设置字体的前景色ForegroundColorSpan()//设置字体的背景色BackgroundColorSpan()//设置字体的样式StyleSpan()//设置下划线UnderlineSpan()//删除线StrikethroughSpan()//上标SuperscriptSpan()//下标SubscriptSpan()//链接URLSpan()-->需要添加setMovementMethod方法附加响应//字体外观设置（依次包括字体名称，字体大小，字体样式，字体颜色，链接颜色)TextAppearanceSpan()//项目符号BulletSpan()//图片ImageSpan()//设置字体(default,default-bold,monospace,serif,sans-serif)ss.setSpan(new TypefaceSpan("sans-serif"),0,4, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new AbsoluteSizeSpan(30,true),4,10,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new RelativeSizeSpan(0.5f),10,14,Spanned.SPAN_EXCLUSIVE_INCLUSIVE);ss.setSpan(new ScaleXSpan(1.5f),14,18,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new ForegroundColorSpan(Color.BLUE),18,22,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new BackgroundColorSpan(Color.YELLOW),22,26,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new StyleSpan(Typeface.BOLD),26,30,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new UnderlineSpan(),30,33,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new StrikethroughSpan(),33,36,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new SuperscriptSpan(),39,40,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new SubscriptSpan(),43,44,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new URLSpan("http://www.baidu.com"),44,46,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ColorStateList color = null;ColorStateList linkColor = null;XmlResourceParser parser = getResources().getXml(R.drawable.colorselector);try {color = ColorStateList.createFromXml(getResources(),parser);} catch (XmlPullParserException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}try {linkColor = ColorStateList.createFromXml(getResources(),parser);} catch (XmlPullParserException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}ss.setSpan(new TextAppearanceSpan("serif",Typeface.BOLD_ITALIC,40,color,linkColor),46,50,Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);Drawable drawable = getResources().getDrawable(R.mipmap.ic_launcher);drawable.setBounds(0,0,drawable.getIntrinsicWidth(),drawable.getIntrinsicHeight());ss.setSpan(new ImageSpan(drawable), 50, 54, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);ss.setSpan(new BulletSpan(BulletSpan.STANDARD_GAP_WIDTH,Color.RED),0,ss.length(),Spanned.SPAN_COMPOSING);mTextView.setMovementMethod(LinkMovementMethod.getInstance());mTextView.setText(ss);}
}
