TextView使用Paint设置下划线删除线效果

TextView tv1 = findViewById(R.id.tv1);
tv1.getPaint().setFlags(Paint.UNDERLINE_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG);//设置下划线

TextView tv2 = findViewById(R.id.tv2);
tv2.getPaint().setFlags(Paint.STRIKE_THRU_TEXT_FLAG | Paint.ANTI_ALIAS_FLAG);//设置删除线

TextView tv3 = findViewById(R.id.tv3);
tv3.getPaint().setFakeBoldText(true); //加粗
