代碼中動(dòng)態(tài)設(shè)置
方法1 ：只單純?cè)O(shè)置粗體和正常
//android中為textview動(dòng)態(tài)設(shè)置字體為粗體
TextView textView = (TextView)findViewById(R.id.textView);
textView .setTypeface(Typeface.defaultFromStyle(Typeface.BOLD));
//設(shè)置為不加粗
textView.setTypeface(Typeface.defaultFromStyle(Typeface.NORMAL));
方法2 ：同時(shí)搭配Fontfamily （此方法會(huì)覆蓋方法1）
//android中為textview動(dòng)態(tài)設(shè)置字體為粗體
TextView textView = (TextView)findViewById(R.id.textView);
//其中"sans-serif"為上面介紹的fontfamily的字符串名字交煞，
//這個(gè)最好用一個(gè)string 資源映射，便于使用
textView .setTypeface(Typeface.create("sans-serif",Typeface.BOLD));
//同理 設(shè)置為不加粗
textView.setTypeface(Typeface.create("sans-serif-thin",Typeface.NORMAL));
