1设置多种文字大小

String text = "您已经连续走了5963步"
int start = text.indexOf(5);
int end = text.length();
Spannable textSpan = new SpannableStringBuilder(text);
textSpan.setSpan(new AbsoluteSizeSpan(16),0,start,Spannable.SPAN_INCLUSIVE_INCLUSIVE)；
textSpan.setSpan(new AbsoluteSizeSpan(26),0,start,end,-1,Spannable.SPAN_INCLUSIVE_INCLUSIVE);
textSpan.setSpan(new AbsoluteSizeSpan(16),,0,end,-1,end,Spannable.SPAN_INCLUSIVE_INCLUSIVE);
TextView textview = (TextView) findViewById(R.id.text);
textview.setText(textSpan);

2 TextView设置超链接

//将TextView的显示文字设置为SpannableString
testText.setText(getClickableSpan());
//设置该句使文本的超连接起作用
testText.setMovementMethod(LinkMovementMethod.getInstance());
//设置超链接文字
private SpannableString getClickableSpan() {
     SpannableString spanStr = new SpannableString("使用该软件，即表示您同意该软件的使用条款和隐私政策");
//设置下划线文字
spanStr.setSpan(new UnderlineSpan(), 16, 20, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置文字的单击事件
spanStr.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
       startActivity(new Intent(MainActivity.this, UsageActivity.class));
       }
}, 16, 20, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置文字的前景色
spanStr.setSpan(new ForegroundColorSpan(Color.GREEN), 16, 20, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置下划线文字
spanStr.setSpan(new UnderlineSpan(), 21, 25, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置文字的单击事件
spanStr.setSpan(new ClickableSpan() {
@Override
public void onClick(View widget) {
startActivity(new Intent(MainActivity.this, PrivacyActivity.class));
}
}, 21, 25, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
//设置文字的前景色
spanStr.setSpan(new ForegroundColorSpan(Color.GREEN), 21, 25,                Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
   return spanStr;
}
